Heavy Duty Turning Center

The PUMA 500 turning centers are the most powerful machines in their class. Designed for heavy and interrupted cutting, holding long term accuracies, and maintaining superior finishes. High metal removal rates along with rapid positioning and high speed turret indexing, guarantee unmatched cycle times when real performance is essential. Proven manufacturing techniques and ultra rigid construction are combined with advanced technological features to produce superior machine with exceptional values.

The Most Powerful Machines in Their Class

Main Spindle

The 45 kW(PUMA 500) spindle motor provides power for heavy stock removal,greatly reducing the number of roughing passes required. The reliable digital ACspindle motor provides fast acceleration and is maintenance free. The preloadedspindle bearings are specifically calibrated to maintain the perfect balance of rigidityand speed. The geared headstock ensures optimal power throughout a wide speedrange. Full power is available from 76 r/min on the where the low end torque is 5645N.m. The large diameter spindle can handle chucks up to 813 mm in diameter.

The headstock casting is made of Meehanite andribbed on the outside to increase the surface area forbetter heat dissipation. The headstock and mainspindle are manufactured in a temperaturedcontrolled environment then assembled and testedin our clean room. The heavy duty cartridge typespindle is supported by a double row of cylindricalroller bearings in the front and rear, with duplexangular thrust bearings in between. The cylindricalroller bearings feature a large contact surface whichensures the highest rigidity for heavy loads andsuperior finishes. All spindle bearings arepermanently grease lubricated precision class P4.

The large 12 station heavy duty turretfeatures a large 400 mm Curvic couplingdiameter and 213640 N of hydraulic clampforce. This heavy duty design providesunsurpassed rigidity for heavy stockremoval, fine surface finishes, and extendedtool life. The exceptionally stable turret has avery wide 150 mm turret plate to ensurelong boring bar over-hang ratios. Indexingrepeatability is ±0.0005 degrees. Turretindexing is non-stop bi-directional. Anextremely reliable high-torque hydraulicmotor provides for quick turret indexing. 32mm square tool holders are mounteddirectly to the turret. The boring bar capacityis 80 mm. The turret features a flexibledesign, allowing for left or right handed, IDor OD tool placement.

The turret features BMT styletooling in which the toolholders are mounted directiyto the turret’s periphery using4 large bolts. This type ofmounting system allows aextremely high degree ofrigidity.

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.

Asix Drives

The programmable tailstock body is mountedon the same guideway surface as theheadstock. The heavy casting, large 150 mmdiameter quill, and precision Morse Taper #6live center provide outstanding rigidity. The150 mm quill stroke is activated by either theprogram and foot switch. Auto lubrication isprovided to the quill and guideways.

Programmable TailstockDouble Pretensioned Ball Screw

Axis Drive Construction and Tail Stock

Both the X and Z axes feature doublepretension ed 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.

Bed and Way Construction

Rapid Traverse

Doosan Infracore precision machine tools are internationally known for theirdurability, rigidity and high accuracy. Only well proven and time testedmanufacturing techniques can produce machines of this quality.

The PUMA 500 is a true 60 degree slant beddesign. The bed is a one piece casting with boththe saddle and tailstock guideways in the sameplane to eliminate thermal distortion. The heavilyribbed torque tube design prevents twisting anddeformation. Fine grain Meehanite processed castiron is used because of its excellent dampeningcharacteristics. This design ensures high rigiditywith no deformation during heavy cutting. Theslant angle allows for easy loading , changing andinspection of tools. All guide ways are groundwrap-around rectangular type for unsurpassedlong-term rigidity and accuracy. The guideways arewidely spaced to ensure stability and fully

protected. Each guideway is induction hardenedand precision ground. A fluroplastic resin, RulonⓇ

142, is bonded to the mating surfaces, for its wearand low friction characteristics and then handscraped for a perfect fit and center height.

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

The high pressure flushes chips out of drilled holes, reduces theneed for peck drill cycles, exceeds the requirements of mostinsert drill manufactures and significantly increases tool life.

The separate, large 310L capacity coolant tank and chip pan areseparate from the machine bed to prevent heat transfer and easycleaning.

Eco-Friendly Design

Metered Way Lubrication

Hydraulic Power Unit

Oil Skimmer(Opt.)

Automatic lubrication is provided to all guideways, ball screws andthe tailstock quill. A maintenance free piston distributor delivers aprecise quantity of oil to each lubrication point. The 2.7L reservoirlasts up to 80 hours. A low level alarm prevents the machine fromrestarting without lubricant.

Automatic Tool Setter(Opt.)

Coolant System

The automatic tool setter reduces set-up time by minimizing theneed for skim cuts, measurements and entering tool offsets. The toolsetting arm is moved by an electric motor and can be controlledthrough the program.
