CYLINDRICAL GRINDER
CYLINDRICAL GRINDER
G32P/G38P Series

 

 

  1. Heavily ribbed box-type base is made of Meehanite castings, providing excellent rigidity to ensure machine stability.
  2. Hydraulic, coolant and lubrication systems are separated from machine to eliminate       vibration and dissipate heat.
  3. Sturdy rigid-designed workhead is electronically controlled giving variable spindle speeds ranging from 30-350RPM.  Workhead swivels 90°CCW to 90°CW for various grinding operations. A dual oil seal and cover prevents coolant seepage into the workhead.
  4. The design of the tailstock is both rigid and robust.  Housed in a cast body, the hardened nitralloy steel sleeve is designed to carry a MT4 center.
  5. Optional hydraulic tailstock with foot pedal is available for easy loading and unloading of parts.
  6. Cartridge type wheel spindle is equipped with four super precision class 7 (ABEC) bearings incorporated with 7 1/2 HP spindle motor ensure high accuracy.
  7. One V and one flat hand-scraped guideways are Turcite coated and incorporated with an automatic lubrication system and micro-stepping motor.  Smooth movement of the Wheelhead delivers longer way life with superior positioning accuracy and repeatability. 
  8. A special upper slide design adds 7” (180mm) in total wheelhead travel and increases      grinding capacity.
  9. Rigid table with box-type structure travels on a cushion of oil with no metal-to-metal contact. Table is fully supported in the full travel to avoid overhang.  A swiveling table dial indicator enables rapid cylindricity corrections and taper grinding applications.
  10. Slideways, leadscrews are continuously lubricated by an auto-lube system to ensure long service life and maintain maximum accuracy.
  11. The hinged, swing-down internal grinding attachment (optional) swings down into working position easily and quickly. A patented locking device adds safety as it prevents the ID attachment from swinging down abruptly.
  12. PLC control uses a menu-driven LCD touch screen is easy to learn and easy to set.  Simply fill in the blanks to set total grinding amount, rough increment, fine increment, spark-out passes, feeding direction, parking position, and retracting clearance, and presscycle start to complete automatic grinding cycle.
