Study of MITUTOYO LH 600Study of MITUTOYO LH 600

In PMSE, inspection of jigs, fixtures, gauges, etc. is performed on MITUTOYO LH 600.

It is an autonomous working height measuring instrument including measuring programs controlled by microprocessor.

Basic FunctionsBasic FunctionsSurface to surface measurementsSurface to center lineCenter line dimensions of bore and shaftsInternal and external dimensions etc

All these dimensions are within tolerance of 0.0004mm

Advantages of MITUTOYO LH 600Advantages of MITUTOYO LH 600

1. Easy operation 2. Automatic loading of measurement

positions3. Tolerance judgment and warnings4. Wide range of measurement functions5. Printout and external output of

measurement results6. Selection of output items7. Part programs8. Statistical Processing

Squareness measurement

ConclusionConclusionWe can use this Precision measurement

instrument which will give the exact readings.

This will help us to improve the quality of product.

This machine is simple to use and maintenance is negligible.

Quality of product increases the production and decreases the cost of the product.

DESIGN OF DRILLING FIXTURE FOR DESIGN OF DRILLING FIXTURE FOR MACHINE CENTERMACHINE CENTER

Introduction: ◦A fixture is a work holding device which only

holds and positions the work, but does not in itself guide locate or position the cutting tool.

◦Drilling fixture is sometimes also called as Drilling jig.

◦The setting of the tool is done by machine adjustment and a setting block or by using slip gauges. A fixture is bolted or clamped to the machine table.

NEED OF FIXTURE:NEED OF FIXTURE:1. Quantity is more.2. Same type of settings for housing.3. All housings must be identical.4. To maintain length of 75mm and

controlled diameter of Ø64 is needed. 5. Time required for setting is more.

(20min/job) 6. To reduce idle time to minimum.7. To ensure safety of operation.8. Lack of skilled workers.

JOB DESCRIPTION:JOB DESCRIPTION:A simple Housing required for ‘Line Boring

Fixture’. Material of housing is MS. Maintained length of 75mm is required from one

side. Also hole is of maintained diameter.

Improvement in Cylindrical grinding Improvement in Cylindrical grinding process for precision maintenance process for precision maintenance

Aim : To grind ‘Rotating sleeves’ on cylindrical grinding machine and to control the outer and inner diameter within tolerance level.

Why precision is needed?◦For inner diameter◦For outer diameter

ROTATING SLEEVES:ROTATING SLEEVES:

Traditional method of cylindrical grinding process

Problems faced during processSolutions

◦For outer diameter◦For inner diameter

Design of a mandrel Design of new spindle

ConclusionConclusionThis improvement program plays an

important role in reducing time consumption and increasing production rate.

This new improved method of cylindrical grinding is now accepted by PMS Engineers and implemented.
