Background

Boring operations involving rotating tools are applied to machine holes that have been made through methods such as pre-machining, casting, forging, extru-sion, ame-cutting, etc. Roughing opera-tions are performed to open up the exis-iting hole to within large tolerances and usually to prepare for nishing, which makes the hole to within tolerance and surface nish limits.

Typically, boring operations are per-formed in machining centres and vertical boring machines. The rotating tool is fed axially through the hole. Most holes are through-holes, often in prismatic or round components. External boring operations can be accomplished using specially adapted boring tools.

The most common size holes being bored are 30 to 100 mm diameter.The range of Sandvik Coromant boring tools covers 23 to 550 mm for roughing and 3 to 975 mm for nishing.

As regards hole depths, four times the hole diameter is generally the maximum recommended depth. Various tools have individual maximum hole depths. For rough and ne boring of deeper holes - of six times the diameter - damped boring tools with tuned tool bodies should be employed.

As regards hole quality, nish boring can typically achieve holes within tolerances of IT 9 with some achieving IT6. Surface nishes better than Ra 1 micron can be achieved. Finish tools have adjustment possibilities to accurately pre-set cutting edges. In principal, however, a boring tool designed for roughing can also be used to achieve holes with a high sur-face nish and to within close tolerances as only one of the inserts generates the surface.

Boring operation typesBoring operations are divided into:- single-edge cuts- multi-edge cuts- step-boring- reaming

Single-edge boring is usually applied for nishing operations and for roughing and nishing in materials where chip control is demanding. A single-edge boring tool may also be a solution when machine power is a limiting factor.

Multi-edge boring, involving two or three cutting edges, is em-ployed for roughing operations where metal removal rate is the rst priority. High productivity levels can be maintained by allow-ing two or three inserts, set at the same axial height, each to machine at the recommended feed per tooth. This results in a high feed per revolution through the hole.

Step-boring is performed in roughing by a boring tool having the inserts set at different axial heights and diameters. This also improves chip control in demanding materials with the different depths of cut of up to 1.0 or 1.5 times the cutting edge length. Depths of cut of 0.5 times the cutting edge length can be di-vided into smaller cuts, providing smaller chips.

Reaming is a light nishing operation performed with a multi-edge tool giving high-precision holes. Very good surface nish and close dimensional tolerance are achieved at high penetra-tion rates. The pre-machined hole needs to be within close lim-its and the radial depth of cut is small.

Boring toolsA boring tool is usually a modular tool, consisting of a basic holder, adaptor and a cutting unit in the form of a cartridge, slide or ne boring unit. A ne boring head holds a boring bar which is radially adjust-able and a reamer has a tool shank with a close pitch head with brazed blades. The tools are radially adjustable within a spe-cic diameter range.

The smallest diameter holes, from 3 mm upwards are bored with the ne boring heads while largest holes of up to 975 mm are nish-bored with a single-edge tool having an adjustable extension-slide mounted on an eccentric bar.

A dedicated boring tool is the best so-lution for operations on components in small to medium batches, with the key features being good productivity pen-etration rate -and high versatility one tool used for several hole diameters.

Boring tools for roughing with more than one cutting edge have relatively simple ad-justment possibilities and it is preferable

to use a tool pre-setting facility, however, a modern design such as CoroBore 820 can also be set using Vernier calipers.

Boring tools for nishing with one cut-ting edge must be settable to within mi-crons and, for this reason, the Sandvik Coromant range of boring tools are set-table to within 2 microns. Tools should be set in a tool pre-setter. With only one cutting edge, the nishing tool will experi-ence some degree of radial deection during machining. This means that a pre-measuring cut is normally needed, fol-lowed by an adjustment of the tool.

Different insert carriers are employed on boring tools and these are dedicated to the type of tool (slides, cartridges, boring bars and ne-boring units). The ne-bor-ing unit is used in special tool solutions and can be mounted in blind holes with-out the need for locking after setting.

The mechanism of CoroBore 825 can be used for special tool solutions. It is more rigid than the ne boring unit but

does require access from the back of the shank and for the mechanism to be locked when set.

The reamer provides through-holes with high surface nish and dimensional accu-racy at high penetration rates.

The choice of tool for single-edge, multi-edge or step-boring operations is very much down to capability and requirement. Roughing tools are primarily multi-edge and nishing are single-edge tools.Roughing tools include CoroBore 820, DuoBore (R391) and heavy duty boring tools (R391.B-R), all tools being capa-ble of all the three operations.Finishing tools include CoroBore 825, ne boring tools (R391.B..-F, ne boring head and the Reamer 830.

RoughingCoroBore 820 is rst choice providing high metal removal capability through boring with three inserts. Power require-ment is higher with several cutting edges engaged. All three inserts are set to the same diameter and height for high-pro-ducitivity boring while for step-boring, the inserts are set at different diameters and heights. This achieved by using different shims placed between the tool adaptor and slide, where the highest insert is set for the smallest diameter and the lowest for the largest.

When single-edge boring with CoroBore particularily for nishing or when ma-terials with demanding chip control is involved - only one insert-slide is used, with the other two slides replaced by cov-ers to maintain the balance of the tool and to be protected.

Duobore has two inserts and needs less power. For high-productive rough step boring, the two inserts are set to the same diameter and height in the tool providing a penetration rate giving dou-ble the recommended feed per tooth. For step-boring the tool setting principle is the same as for CoroBore 820.

The maximum recommended depth of cut is half the cutting edge length. Each insert can be set accordingly making it possible to have depths of cut up to the full cutting edge length. The depth of cut of half the cutting edge length can be divided into two smaller cuts, giving smaller chips advan-tageous in demanding materials.

When single-edge boring is employed, only one of the insert-slides is used, leaving the other seat to be protected by a cover that radially supports the slide.

The heavy duty boring tools, primarily for larger diameters, are also capable of all three operations types. The tool design re-sembles the boring tools for the smaller diameter ranges but with mounting dimen-sions for standard milling arbour. Approxi-mate settings are performed by moving sides across the adaptor or bar followed by ne setting on the cartridge.

With two cartridges, each mounted on an extension slide, which is radially adjustable on an adapter and using shims, the cutting edges can be set in accordance with the operation type to be employed. The tool for the larger diameter range uses a wide bar mounted on the adaptor and on which two extension slides can be set.

FinishingCoroBore 825 is the rst choice for gen-eral nish boring within the diameter range of 23 to 250 mm. This boring tool has a single cartridge, with high stability and easily adjustable radially to within 2 microns, to achieve IT6 tolerances and surface nishes within Ra 1 micron. The CoroBore 825 nsihing tool complements the CoroBore 820 roughing tool for the same hole diameter and depth range to provide a modern solution for boring.

The ne boring tools for larger diameters consists of two different designs : one for single or twin-edge boring of internal diameters 250 to 575 mm and external of 138 to 447 mm and one for internal boring of 250 to 975 mm.

Common for both are adapter, bar, slide and ne boring head. Rough setting is carried out by moving the slide along the bar and then adjusting the ne bor-ing head. To avoid large holes becoming oval at high spindle speeds, recommen-dations for a counterweight can be sup-plied. Selecting the most suitable insert and entering angle and the ability to turn the unit provides a high-performance bor-ing tool for high tolerance and surface nish demands.

Fine boring heads hold dedicated boring bars fo diameters 12 to 25 mm and car-bide bars of 16 mm to provide the capa-bility to produce close tolerances (IT6) at high spindle speeds (7000 rpm). With a diameter range of 3 to 44 mm to depths of 13.5 to 128 respectively, these super-nishing boring tools machine at small depths of cut (0.05 to 0.5 mm) and small feeds (0.01 to 0.1 mm). Generally, the rst choice for the boring bar is a posi-tive knife-edge insert in a cermet grade machining at high cutting speeds.

The Reamer 830 covers the diameter range 10 to 31.75 mm with varying hole depths, hole tolerances of IT 7 are achieved along with high concentricity. Easily exchangeable heads are secured by front clamping. The heads accom-modate 4 to 8 cermet brazed blades depending upon diameter. Effective chip evacuation is secured by cutting uid directed to each cutting edge. There is high concentricity and repeatability with a precision coupling.

The combination of multiple cutting edges capable of high cutting speeds re-sults in very high penetration rates. The heads are equipped with left-hand chip utes which push the chips ahead of the reamer, thus necessitating through-holes for machining, but providing an ad-vantage for machining with interrupted cuts as in crossing holes. This cutting action generates cutting forces directed axially into the spindle, increasing the ri-gidity and providing accurate control of the hole diameter accuracy.

Damped boring tools (Silent Tools) should generally be considered for hole depths of more than four times the diameter. DuoBore damped tools are available for roughing operations in the diamter range 25 to 150 mm and with the ability to per-form single-edge, multi-edge and step-bor-ing. Damped ne-boring tools are available from 25 to 269.5 mm diameters.

The tool coupling is a critical part of the total set-up and interface to the machine spindle. If the tool coupling is unsatis-factory as regards stability, strength, ac-curacy and handling, the chain of factors that ensure performance will be broken. A good modular system Coromant Capto with a large range of tool types for roughing and nishing is an important

part of the machining equipment for bor-ing with rotating tools. The system pro-vides the means for a tool and spindle interface with a self-centering coupling that provides the centre of rotation for minimizing the boring tool run-out and making it possible to adapt each tool as-sembly for the operation in question.

Inserts for boringThe selection of indexable insert for bor-ing has a decisive inuence on the out-come of the boring operation. Productivi-ty, reliability and quality is directly related to the performance of the cutting edge. Chip formation, tool-life and cutting data are determined by the combination of in-sert geometry and grade.

As in all internal machining operations, chip control and evacuation are critical. Inserts for boring are essentially the same as for turning, where chipbreak-

ing areas are dened for each geome-try type. Short, thick chips can lead to excessive cutting forces with deection and vibration as the result. Chips that are too long, often in the form of stringy swarf, can accumulate in the hole and cause surface nish deterioration and then chip stocking, leading to break-down.Chips in the form of commas or determined spirals are the ideal.

The depth of cut is determined by the recommended values for each insert ge-ometry. The sharper a geometry is, and the smaller the nose radius, the smaller the depth of cut possible. It may very well be that an increase in depth of cut may lead to harder chipbreaking, while a reduction may lead to insufcient cut-ting edge engagement, with rubbing as a result.If chips are generated sporadically during machining, the depth of cut may be insufcient or excessive.

Building and setting boring tools Building a tool for boring with modular holders, adaptors, extensions, reduc-tions and cutting units provide a broad range of possibilities to perform opera-tions and for optimization. Long reach tools with the best stability, the inclu-sion of damped tools and exibility for use in other operations are some of the main advantages. This is especially im-portant when building nishing tools as the cutting edge should be moved away from the machined surface in the bore to avoid retraction marks. It is then also vital that the recommended torque val-ues are followed for assembly and that a suitable xture is used and that a good tool pre-setter is used.

Each boring tool is delivered with setting instructions. For nishing cuts, it is often advisable that a measuring cut is made to see what adjustment is needed to compenstae for tool deection. Special boring tools should be considered for opti-mization, especially when large batches or repetitive orders involving the same operation. CoroBore 820 can be combi-ned with CoroBore 825 to accomplish roughing and nishing one hole diameter. Tool combinations for machining differ-ent diameters, chamfers and counter-bores can be made.

The factors for successful boring with tool assemblies are similar to those as-sociated with internal turning.

With all parameters related to accuracy and surface nish generation under con-trol, it is possible to achieve very good tolerance levels and surface nishes in boring. The surface nish in boring opera-tions is inuenced by various parameters component and xturing stability, ma-chine tool condition, tool holding stability, cutting data and the choice of indexable insert. The choice of Wiper inserts will

inuence not only surface nish but also the productivity of the operation.

Surface nish is directly related to the same parameters as for rough boring but with the depth of cut also playing a role. Generally depths of cut are quite shallow but there is a lower limit to depth which relates to insert geometry and feed rate. Most boring tools for nishing have only one insert and are as such prone to de-ection during cut. When the cutting depth is smaller than the lowest depth-limit, the insert will tend to ride on the pre- machi-ned surface, only scratching and rubbing it, leading to unsatisfactory cutting action and and hence the nal result.

Ways of countering vibrations in boring:

- Uset the largest tool-diameter possible.- Use shortest tool over-hang possible.- Use tapered shanks/reductions whenever possible.- Use dedicated tools for longer overhangs - damped tools.- Check machine spindle, run out, wear, clamping force etc- Check that all units in the tool assembly are assembled correctly with the correct torque.

- Reduce speed- Reduce feed/increase feed- increase depth of cut (nishing)- Use smaller nose radius (nishing)- Use insert with sharper cutting edge- Use 90 entering angle (roughing)- Check workpiece clamping

Success factors for boringThe prime factors to be considered for successful boring are:- Tool overhang and diameter of tool- Cutting data and chip control- Insert nose radius and geometry- Cutting uid- Damped tools- Tool coupling- Specially for reaming

Tool overhang and diameterTool overhang is the distance from gauge line, or extending out of boring head, to the cutting edge and related to the dia-meter of shank. This ratio should be a maximum 4 x shank diameter.

For each length equal to the tool diam-eter that the tool is extended, the deec-tion is increased 8 times.Recommendations:- Use largest tool diameter possible.- Use shortest overhang possible.- Use tapered shanks/reductions when-

ever possible.- Use dedicated tools for longer over-

hangs eg. silent tools.

Cutting data and chip control1. RoughingFollow the recommendations for the in-sert geometry and grade in question.

Initially, however, the cutting speed should be reduced to about 50 % of recommen-dations to ensure that proper chip evacu-ation takes place. Rough boring, par-ticularly when using three cutting edges, generates as a lot of chips, that must be transported out of the hole efciently.

Maximum depth of cut should not exceed half the cutting edge length.

2. FinishingFeedThe required surface nish restricts the maximum feed for any given nose radius. The adjustments available to inuence chipform is therefore limited. The chips must have a suitable form to be evacuted without damaging the surface of the hole. Choice of insert, therefore, becomes very important.

By using a Wiper insert, the surface nish can be dramatically improved us-ing the same feed.However, the Wiper inserts do need more stability as they exert about 10% more radial pressure which increases the risk for vibrations.

Depth of cutWhen nish boring the maximum depth of cut is not so much related to the size

of the insert as the design of the ge-ometry. The recommended inserts and geometries for nish boring are design to working at small depth of cuts. When excessive depth of cuts are used, the chips can jam between workpiece and tool, causing the cutting edge to break.

Cutting speedThe maximum cutting speed is not so much limited by tool life as vibration. Starting values, therefore, are recom-mended to be no more than 50% of that recommended for external turning.

Reasons for vibration tendencies can be unsuitable insert geometry, entering an-gle, nose radius, etc. Generally, the cut-ting edge should cut as easily as possi-ble : inserts should have a very positive top rake, sharp cutting edge and small nose radii. The entering angle should be as close to 90 degrees as possible. The T-Max U knife-edge insert meets these requirements and is recommended as rst choice.

Benets

- Sharper cutting edge, less vibrations and

better surface nish

- Higher precision

- Better clearance on secondary cutting edge

The following geometries are recommended for nish boring:

-K 0.07 0.5 0.05 0.7 0.15

-WK 0.07 0.5 0.05 0.4 0.22

-PF 0.1 0.5 0.06 0.7 0.2

Nose radiusRadial cutting forces are related to the size of the nose radius. A large nose ra-dius will, therefore, deect a boring bar more than a smaller nose radius and be more susceptible to vibrations.Recommended nose radius is 0.2 mm. Do not us larger nose radius than 0.4 mm for nish boring.

Cutting uidMust be used when nish boring to close tolerances and to achieve good surface nish which is important:- To transport chips quickly away from the cutting zone and out of the bore.- To limit the heat-expansion of work piece and tool

Damped toolsDamped tool should be used when a tool overhang of more than 4 x D has to be employed.

First choice for roughing in damped tools:- knife-edge insert- entering angle 90 degrees

First choice for nishing in damped tools:- knife-edge insert- entering angle 92 degrees

When using damped tools in assemblies, take care to hold the tool bodies correctly so as not to damage the adaptor, render-ing it ineffective. These are easily de-formed due to the thin wall thicknesses. Correct assembly units should be used.

The tool couplingA good coupling for the tool and machine interface is imperative for a good boring result. The best result is achieved with Coromant Capto coupling both as spindle and tool interface. The coupling is self centering, thereby centre of rotation and centre of tool assembly coincide minimis-ing runout of the tool. The modular sys-tem makes it possible to tailor tool as-semblies to suit each work piece.

Specially for reamingReaming with the 830 reamer is very effective with high operational security. A basic factor for good reaming perfomance generally is the quality of the hole to be reamed. Reaming should not be expected to correct any locational or straighness errors of the pre-machined hole.

There are a few application hints that will help to assure successful results:

- straightness of pre-machined holes should be within 0.01 mm

- radial depth of cut (ap) shoul be 0.1 mm or more

- the feed rate should be above 0.1 mm/tooth

- emulsion as cutting uid is better than oil due to the cooling properties

- a cutting uid pressure of 4 bars is sufcient

- minimal lubrication techniques can be used

- vibrations at hole entry can be reduced by increased feed and/or a slight hon-ing of the cutting edges

- the tool holding should be of good quality, such as the precision chucks CoroGrip and HydroGrip.

Dimensions, mm

Turning the adjusting nut sets the bore diameter. The nut has a scale where each divi-sion is equivalent to 0.01 mm change of radial depth of cut.With the exception of the smallest size, all units have vernier scales on the collar, which facilitates radial adjustments of 0.001 mm.

Please note: When setting a unit, mounted in angular position, the axial position changes

equal to-radial movement/tan 53 8. When designing special tools, please calculate the nominal diameter to be machined

with the unit set to the centre of the adjustment range, e1. This makes it possible to adjust the nominal bore plus and minus.

Never unscrew the cartridge further than indicaed by the tongue of the setting key for the unit concerned.

If the limit is exeeded the unit can not be repaired.The dimensions and tolerances in the table below must be adhered to for the units to be able to function.

Setting the boring unit R/L148CT-Max ne boring units are precision tools for mounting in special tools capable of machining close tolerances.Features: Can be mounted in blind holes Adjustment is made from the front The units are self-locking, i.e. there is no need for unlocking before or locking after

Cartridge replacement in ne boring unit R/L148C

1. Clamp the mounting xture in a vice.2. Place the ne boring unit in the xture (g A) and turn it until the spring loaded

plunger ts into the slot in the pilot at the back of the cartridge. Check that it has located by turning the unit round, making sure the plunger follows with it.

3. Fit the xture nut over the unit.

4. Press the unit in and turn until the xture pin locates in one of the holes in the sleeve. The correct position is when the arrow on the xture body is in line with the cutting edge (g B).

5. Tighten the xture nut so that play can be felt in the thread of the ne boring unit. This occurs when the adjusting nut becomes easier to turn (g C).

6. Remove the cartridge by turning the adjusting sleeve clockwise using the setting-key. When the cartridge starts to rotate with the sleeve unscrew it counter-clock-wise.

Please note. If the xture nut is loosened in this position a cartridge can not be mounted and the ne boring unit is destroyed.

Make sure that all parts are clean before assembly.

7. Screw in the cartridge by hand until the plunger locates in the cartridge slot. The cutting edge should then be in line with the arrow on the xture body. If the cutting edge lies at 180 relative to this arrow, use the follow-ing procedure:

a) Turn the adjusting sleeve half a revolution clockwise with the setting key. b) Turn the cartridge clockwise by hand to the correct position. Hold the cartridge

in this position while turning the adjusting sleeve counter-clockwise with the setting key (g E). When the cartridge pilot reaches the pilot hole of the bottom of the unit a critical point is reached, as the pilot must locate in the pilot hole without being damaged.

Fitting is facilitated by slightly turning the cartridge backwards and forwards, and at the same time gently turning the adjusting sleeve counter-clockwise.

8. Loosen the xture nut and remove the ne boring unit.

When replacing a cartridge, the mounting xture 148A-20 must be used. Failure to do this may result in damage to the unit. The mounting xture takes up the pre-tension when the cartridge is removed. The same xture is used for right and left hand units.

The following procedure should be observed

Non-ferrous materialsChoosing polycrystalline diamond tipped inserts (PCD) or cemented carbide inserts?The PCD grade CD10 and diamond coated grade CD1810 can be a useful alternative to cemented carbide for nishing and semi-nishing in non-ferrous metals and non-metallic materials.

Use diamond for improving: tool-life surface nish

stable conditions machining economy

chip control edge security low cost per edge

CBN in cast-iron, hardened and heat resistant materialsCubic boron nitride grades CB7020, CB20, CB7050 and CB50CBN inserts can increase productivity in many difcult metal cutting operations up to 100 times better than carbide or ceramics in terms of longer tool-life and/or higher metal removal rate.

CBN is recommended primarily for nishing operations: CB7050/CB50 for cast-iron and heat resistant materials. CB7020/CB20 for continuous and light interrupted cuts in hardened parts.
