The headstock casting is made of Meehanite and mounted on the outside to increase the surface area for better heat dissipation. The headstock and main spindle are manufactured in a temperature-controlled environment, then assembled and tested in an oil-clean room. The heavy-duty cartridge-type spindle is supported by a double row of cylindrical roller bearings in the front and rear, with complex angular thrust bearings in between. The cylindrical roller bearings feature a large contact surface, which ensures the highest rigidity for heavy loads and superior finishes. All spindle bearings are permanently grease lubricated, precision class P.

The 45 kW PUMA 500 spindle motor provides power for heat stock removal, greatly reducing the number of roughing passes required. The reliable digital AG spindle motor provides fast acceleration and is maintenance-free. The preloaded spindle bearings are specially calibrated to maintain the perfect balance of rigidity and speed. The geared headstock ensures optimal power throughout a wide speed range. Full power is available from 76 kW at the low end torque range, allowing high spindle speeds. The large diameter spindle can handle chucks up to 813 mm in diameter, as well as powerful low-end torque.

Index time 1st station swivel. Number of tool stations: 12 stations.

The large 12-station heavy-duty turret features a large 410 mm Curvic coupling that holds the tool in place with hydraulic clamp holders mounted directly, ensuring rigidity. This heavy-duty design provides unsurpassed rigidity for heavy stock removal, fine surface finishes, and extended tool life. The exceptionally stable turret has a very wide 150 mm turret plate to ensure rigidity and high boring bar over-hanging ratios. Indexing repeatability is precise. Turret indexing is non-stop bi-directional. An extremely reliable high-torque hydraulic motor provides quick turret indexing. 32-minute square tool holders are mounted directly to the turret. The boring bar capacity is 80 mm. The turret features a flexible design, allowing for left or right-handed tool placement.

Both the X and Z axes feature pre-tensioned ball screws, supported on each end by precision class P angular contact thrust bearings. Each axis is powered by a maintenance-free digital AC servo motor. These high-precision drive motors are connected to the ball screws without intermediate gears for quiet and responsive slide movement with virtually no backlash. Auto lubrication is provided to the quill and guideways.

The PUMA 500 is a true 60-degree slant bed design. Each guideway is induction-hardened and precision ground. The bed is a one-piece casting, with both a fluoro-plastic resin, Rulon material, used to eliminate thermal distortion. The heavily ribbed Coryue tube design prevents twisting and is scraped for a perfect fit and center height. Meehanite processed cast iron is used for its excellent damping characteristics. This design ensures high rigidity with good deflection, handling heavy cutting loads. The slant angle allows easy inspection of tools. The guideways are ground wrap-around rectangular type for unsurpassed long-term rigidity and accuracy. The slant-design bed makes the work go smoother, with chip removal much easier. Tough tubular construction stands up to the hardest cutting jobs.

X-axis: 10 m/min
Z-axis: 12 m/min
Scraping of Slideway: Outstanding rigidity for high feedrates

Automatic lubrication is provided to all guideways, ball screws, and the tailstock quill. A maintenance-free piston distributor delivers a precise quantity of oil to each lubrication point. The reservoir lasts up to 80 hours. A low-level alarm prevents the machine from restarting without lubricant.

The automatic tool setter reduces set-up time by eliminating the need for skim cuts, measurements, and entering tool offsets. The tool setting arm is moved by an electric motor and can be controlled through the program.

The high-pressure flushes chips out of drilled holes, reduces the need for peck drill cycles, exceeds the requirements of most insert drill manufacturers, and significantly increases the life of tools.

The coolant is kept clean, and its life is extended with bed casting. The separate, large 310-liter capacity coolant tank and chip pan are channels from the Z-axis to a separate reservoir. A belt oil skimmer is located separately from the machine bed to prevent heat transfer and to easily pick up and remove waste oil from the coolant tank that is easily drained and cleaned.
