Both gantry axis are driven by reliable Fanuc servomotors. The gantry is programmed from the machine CRT using standard G&M codes. The longitudinal axis (Z) has a rapid traverse rate of 3,900 IPM The up/down axis (Y) has a 3,500 rapid traverse rate. The A2 type gantry is for a right side stocker and its Z-axis extends beyond the right side of the machine. The A3 type gantry can accommodate stockers on both sides. The A3 gantry arm extends beyond both sides of the machine. A3 type can also be used with one stocker.

3 In this case a second stocker can be easily added in the future, as could a special input/output conveyor. GRIPPER HEADS The gripper heads mount on the bottom of the Y axis gantry slide. Each flange type gripper head has two 3-jaw chucks. One to hold the part coming out of the main spindle chuck and the other for the new part to be loaded. Maximum part weight is 3 lbs. on Puma 300 models unless otherwise noted. Flange gripper head prices include a set of gripper jaws as well as a gripper jaw-boring fixture. STOCKER: The 14-pallet stocker is attached to the turning center for fast and accurate part placement. Depending upon the gantry type, stockers can be mounted on either side, or both sides of, the turning center depending on customer s need for floor layout or application. The stocker has a safety cage protecting on all sides. The cage is hinged for easy access to the loader gripper-head and stocker pallets. Large side access doors allow easy access for loading and unloading parts from the stocker. Safety door interlocks prevent the turntable from rotating while the access door is open. Machine spindle and loader still operate while when the stocker access door is open. Two stations of the stocker are in line with the Z-axis of the gantry. These two loading stations lift up to meet the gripper head. Sensors are included to confirm that new part is available to load and also to confirm that finished part is returned to the stocker. The stocker has an operation panel on the front side with manual controls for pallet rotation and load station up and down. A pallet counter is included to stop the cycle when machining is complete. STOCKER PALLETS On the flange type pallets, three vertical rods on each pallet locate parts. A quick adjusting features allows for part diameter changes by moving the rod location simultaneously with one adjusting screw. The length of part determines the quantity that can be stacked on pallets. One set of 14 pallets is required for each stocker. TURN AROUND STATION (Included) A loader controlled pneumatic gripper head attached to the machines tool post can automatically turn workpiece over to be ready for second machine operation Puma230-GL and Puma300-GL turn over stations will turn over part and finish second operation in main chuck before being placed back too stocker. Machines cannot use optional turn over stations without removing its tailstock if so equipped. CHIP CONVEYOR (Included) The Puma 300 turning centers with gantry are prepared from the factory for rear discharge chip conveyors. Chip conveyor is an optional feature. Prices are shown on the optional accessories page of this proposal. Chip conveyors for cast iron, cast aluminum or brass can also be provided. These prices are upon request.

Way Lubrication oil required Mobil Vactra #2 or Shell Tonna T68 * * Cross reference these numbers for other brands MACHINE CONSTRUCTION * BED: The bed is a one piece Meehanite casting incorporating a heavily ribbed torque tube design which inhibits thermal deformation and twisting. The Meehanite cast process produces a fine grain casting with excellent vibration dampening characteristics. The bed guideways are on a 45 degree angle to maintain a minimal and constant distance from tool tip to guideway. This ensures maximum rigidity and virtually no deformation under heavy loads. The slant angle also ensures a perfect chip flow as chips and coolant fall unobstructed into the chip pan. The slant bed lathe is a superior ergonomical design because of the proximity of the chuck, turret and tailstock to the front of the machine. The ease with which operators are able to load/unload parts and change tools minimizes fatigue. * GUIDEWAYS: All guideways are wide wrap-around rectangular type for unsurpassed long-term rigidity and accuracy. The guideways are widely spaced to ensure stability. Each guideway is induction hardened and precision ground. Induction hardening ensures a more consistent hardness and depth of hardness than the less expensive flame hardening process. A fluroplastic resin called Rulon 142 is bonded to mating way surfaces and then hand scraped for perfect fit and center height. This material provides a low friction surface, which virtually eliminates guideway wear. It also provides vibration dampening for better surface finishes. Rulon 142 has superior deformation, wear, and friction characteristics compared with other brands. Friction rate decreases as loads increase. The bed guideways are fully protected by one-piece heavy gauge stainless steel covers on both sides of the carriage. * BALL SCREWS AND AXIS DRIVES: A large diameter double-nut ball screw drives each axis. The high precision Tsubaki ball screws have been specifically selected to achieve the outstanding combination high accuracy, high rapid traverse rates and high feed thrust. Both ball screws are supported on each end. Both X and Z-axis ball screws are pretensioned for accurate positioning and thermal stability. The thrust bearings are precision class P4 (AFBMA-B7) angular contact type. Ball screws are centered between the guideways and are directly mounted to the AC servo motors without intermediate gears or belts to minimize backlash. The Z axis servo motor is mounted on the headstock end of the ball screw. * MAIN SPINDLE AND HEADSTOCK: The robust headstock casting is mounted on the same ground surface as the tailstock to maintain perfect alignment and center height regardless of the bed temperature. The headstock has ribs on the outside of the casting to increase the surface area for heat dissipation. The heavy duty cartridge type spindle is supported by double row cylindrical roller

6 bearings in the front and rear, and duplex angular thrust bearings in between. Cylindrical roller bearings feature a large contact surface which ensures the highest rigidity for heavy loads and high surface finishes. All spindle bearings are precision class P4 (AFBMA-B7) and are permanently grease lubricated. The precision NTN bearings and perfectly balanced spindle allow a high maximum RPM. Front bearing inner diameter is 5.11 on Puma 300MB. * MAIN SPINDLE DRIVE: A high-torque spindle motor provides power for heavy stock removal, reducing the number of roughing passes required. The powerful A.C. motor provides fast spindle acceleration and plenty of low-end torque. Full 30 Hp is available on Puma 300B from 447 RPM. The Puma 300C obtain full 35 HP at 291 RPM. The spindle motor is flange mounted on the side of the bed casting, assuring perfect alignment with the headstock. The Puma 300B have direct drive 1:8 output high torque spindle motors * SERVO TURRET: The non-lifting design eliminates the possibility of chips reaching the coupling. This heavy-duty turret provides high rigidity for heavy stock removal, fine surface finishes, long boring bar overhang ratios, and extended tool life. A high torque servo motor rotates the turret head at high speed. Turret clamp is confirmed by proximity switch. Turret indexing is non-stop bi-directional. Turret indexing is possible during the rapid traverse move away from the work piece. The large diameter 12 station turret features base mounted tooling with all tool holders being mounted to the periphery of the turret. All 12 tooling positions can be live or static. This design gives the machine operator maximum flexibility when setting up a job. Standard turning tool holders utilize 1" square shank tooling and ID tool holders have a maximum diameter of 1.5". Coolant is delivered to the cutting tool via a seal-less coupling built into and running through the center of the turret. * ROTATING TOOLS The 5 Hp rotating tool motor delivers 34.7 ft-lbs. of low end torque. The standard rotating tool holders have a maximum RPM of 4,000. The holders feature precision bearings which are grease lubricated. The holders are bolted directly to the periphery of the turret for maximum rigidity and feature precision grease lubricated bearings. The holders use readily available ER type collets for milling, drilling and rigid tapping. Polar coordinate interpolation is provided for easy C-axis contouring. Rigid tapping is standard. * LUBRICATION: Automatic forced lubrication is provided to all guideways, ball screws, and the tailstock quill. Maintenance free piston distributors deliver a precise quantity of oil to each lubrication point. The piston distributors are non-clogging and the design allows way lube consumption to be minimized. The 1/2 gallon reservoir, mounted on the front of the machine, lasts up to 100 hours. A low-level alarm prevents machine from restarting until oil reservoir is replenished. System pressure is monitored to detect open or broken lube lines. * AUTOMATIC TOOL SETTER: The automatic tool setter reduces set-up time by minimizing the need for manual skim cuts, measurement, and entering of tool offsets. The tool setting arm mounted next to the chuck

7 swings down for setting tool offsets. The arm moves up and down by manually or by program. The arm is made of steel to minimize thermal expansion. A four position touch sensor mounted on the end of the arm allows tool setting in any direction. As tools are touched-off on the sensor, tool offset values are automatically calculated and entered. The automatic tool setter design will clear most chucks up to 12.4" diameter. * COOLANT SYSTEM: A 1.2 Hp high capacity multistage centrifugal pump delivers a high volume coolant through the turret to ball nozzles at each turret station. The pump delivers 65 PSI of pressure, meeting the requirements of most insert drill manufacturers. The high pressure flushes chips out of the drilled holes and reduces the need for time consuming peck drilling cycles. High coolant pressure also significantly increases tool life. A flow control valve located at the coolant pump allows pressure and flow rate to be reduced if necessary. The coolant tank and chip pan are separate from the machine bed, preventing heat transfer from the coolant to the machine casting. The coolant pan is mounted on rollers to facilitate removal for cleaning. Screen filters prevent small chips from reaching the coolant pump. * WAYLUBE SEPARATION SYSTEM: The bed casting has channels, which deliver way lube from the Z axis into a separate reservoir. A belt oil skimmer picks up remaining waste oil from the coolant tank and deposits it into the same reservoir. As a result the coolant is kept clean and coolant life is extended. Waste oil tank can be conveniently drained. A sight glass indicates when the used oil should be drained. * CHIP GUARDING: Chips and coolant are contained by the fully enclosed guarding made of heavy gauge sheet metal. The door moves effortlessly on a round steel rail. The double-layer viewing window features tempered safety glass on the inside which resists scratching and an outside layer of lexan which is virtually impenetrable. * CONVENIENT OPERATION: The operators panel is mounted on the right side and is tilted 20 degrees toward the operator for easy viewing. To minimize set-up time, manual controls are provided for turret indexing, spindle, and feed functions. Knobs for adjusting chuck and tailstock pressure are located on the front of the machine. * QUALITY COMPONENTS: Only the highest quality components are used on each Puma 300 series model. Each component has been selected only after rigorous quality and reliability testing. Ball screws are manufactured by Tsubaki, spindle bearings by NTN, and axis thrust bearings by NSK. Hydraulic solenoids, flow controls, and regulators are made by Parker Hannifin. The hydraulic power unit is extremely compact and very quiet (less than 60 db). It also maintains a low oil temperature which minimizes thermal distortion of the turret and tailstock. The Siemens circuit breakers and contactors are both UL listed and CSA approved. Fanuc control packages have been selected for their outstanding combination of performance and reliability.
