High Performance Turning Center

The PUMA 400 series turning centers are without a doubt the

most powerful machines in their class. High metal removal rates,

along with rapid positioning and fast bi-directional turret indexing,

guarantee unmatched cycle times when real cutting is essential.

Massive yet responsive Turning Centers

without compromise. The most powerful

machines in their class.

The headstock casting is made of Meehanite and ribbed on the outside to increasethe surface area for better heat dissipation. The headstock and main spindle aremanu-factured in a temperature controlled environment then assembled and testedin our clean room. Double row of cylindrical roller bearings and duplex angularcontact ball bearings, P4 class of the spindle ensure the highest rigidity andefficiency to transmit motor power to the end.

The high-torque spindlemotor provides power forheavy stock removal, greatlyreducing the number ofroughing passes required.For 3 axis milling models,the motor is a spindle servotype controlling both thespindle in 2 axis mode andfull contouring C-axis in the3 axis mode. Switchingbetween the two modes isnearly instantaneous.

The large 12 and 10 station heavy duty turret features a large diameter Curviccoupling and hydraulic clamp force. The heavy duty design provides unsurpassedrigidity for heavy stock removal, fine surface finishes, long boring bar overhangratios, and extended tool life. Turret rotation, deceleration and clamp are allcontrolled by a reliable high torque-hydraulic index motor. Unclamp and rotationare virtually simultaneous. Turret indexing is non-stop bi-directional, with a 0.25second next station index time. Turning tools are securely attached to the turret bywedge clamps.

The large 12 station heavy duty turret features alarge Curvic coupling diameter. This heavy dutydesign provides unsurpassed rigidity for heavy stockremoval, fine surface finishes, and extended toollife. Indexing repeatability is ±0.0055 degrees. Turretindexing is non-stop bi-directional. An extremelyreliable high-torque hydraulic motor provides forquick turret indexing. 32mm square tool holders aremounted directly to the turret. The boring barcapacity is 60mm. The turret features a flexibledesign, allowing for left or right handed, ID or ODtool placement.

Operator’s Panel

The operator control panel is mounted on anadjustable pendant for easy viewing and accessibilityduring set-up and operation. The layout and locationof the panel is ergonomically designed to be efficientand convenient for the operator. Comprehensivealarm diag-nostics are provided for the machine,control and programming errors.

The programmable tailstock body is mountedon the same guideway surface as theheadstock. The heavy casting, large 120mmdiameter quill, and precision Morse Taper #6live center provide outstanding rigidity. The120 mm quill stroke is activated by either theprogram or foot switch. Auto lubrication isprovided to the quill and guideways.

Asix Drives

Each axis is powered by a maintenance freedigital AC servo motor. These high torquedrive motors are connected to the ball screwswithout intermediate gears for quiet andresponsive slide movement with virtually nobacklash.

Preci-Flex ready rotary tool holders are available on the milling versions. Preci-Flexis a tooling system utilizes the existing ER collet taper in the rotary holders. Thespindle face is precision ground relative to the taper and there are four drilled andtapped holders in this face. The Preci-Flex adapters locate on both the taper and thespindle face for maximum rigidity. A variety of Preci-Flex adapters are available forspecial applications.

Double Pretensioned Ball Screw

Both the X and Z axes features a doublepretensioned ball screw, supported on eachend by precision class P4 angular contactthrust bearings. Both axes are driven by largediameter, high precision ball screws. Each ballscrew has been carefully selected to achieve acombination of high accuracy, high rapidtraverse rates and high feed thrust. All ballscrews are fully supported on both ends.

The 37 kW spindle motor is directly coupled to Baruffaldi 2-speedelectronic transmission, which provides maximum torque. The 2speed gear box with its precision ground gears provide quietoperation at high speed then transfers its power to the main spindlefor vibration free operation resulting in excellent surface finishes.

The PUMA 400 series is a true 45 degreeslant bed design. The bed is a one piececasting with both the saddle and tailstockguideways in the same plane to eliminatethermal distortion. The heavily ribbed torquetube design prevents twisting and defor-mation. Fine grain Meehanite processed castiron is used because of its excellent

dampening characteristics. This ensures highrigidity with no deformation during heavycutting. The slant angle allows for easyloading, changing and inspection of tools. Allguideways are wide wrap-around rectangulartype for un-surpassed long-term rigidity andaccuracy. The guideways are widely spacedto ensure stability and fully protected. Each

guide-way is induction hardened andprecision ground. A fluroplastic resin, Rulon®

142, is bonded to the mating way surfaces,for its wear and friction characteristics andthen hand scraped for a perfect fit and centerheight. Optional long bed enables extra-longshaft machining.

The coolant is kept clean and its life is extended with bed castingchannels from the Z axis to a separate reservoir. A belt oil skimmerpicks up and removes waste oil from the coolant tank that is easilydrained.

The high pressure flushes chips out of drilled holes, reduces theneed for peck drill cycles, meets the requirements of most insert drillmanufactures and significantly increases tool life.

The temperature of the hydraulic oil is regulated by a coolingsystem.

The separate, large 280[370]L capacity coolant tank and chip pan areseparate from the machine bed to prevent heat trans-fer and easycleaning. [ ] : Long bed

Tool Pre-Setter(Opt.)

Coolant System

The automatic tool setter reduces set-up timeby minimizing the need for skim cuts,measurements and entering tool offsets. Thetool setting arm manually or can be controlledthrough the program.

Each axis ball screw is protected by electric torque limiters tominimize damage in the event of a crash. Upon impact, the limiterimmediately stops the machine.

Electric Torque Limiters

Collection of Waste Lubrication Oil

Less waste lubrication oil extends the life timeof the coolant water and cut down the grimeand offensive smell of the machine inside.

Metered Way Lubrication

Automatic lubrication is provided to allguideways, ball screws and the tailstock quill.A maintenance free piston distributor deliversa precise quantity of oil to each lubricationpoint. The 1.8L reservoir lasts up to 80 hours.A low level alarm prevents the machine fromrestarting without lubricant.

No Coolant Leakage

Rigorously designed, manufactured andtested machine covers do not permit coolantleakage in any condition. The factory alwayskeeps our environment clean.
