17.7” X 23.6” Capacity OD Hydraulic Grinder with a PLC controller using a simple menu driven LCD touch screen with 16” Diameter 7.5HP Wheelhead, Universal Table with Variable 1.2-275 IPM Traversing Speeds and an Optional Internal Grinding Attachment.


FEATURES:

  • Heavy ribbed box-type base is made of Meehanite castings, providing excellent rigidity to ensure machine stability.
  • Hydraulic, coolant and lubrication systems are separated from machine to eliminate vibration and dissipate heat.
  • Sturdy rigid-designed workhead is electronically controlled giving variable spindle speeds range from 30 to 350 rpm.
  • Workhead swivels 90 degrees CCW to 90 degrees CW for various grinding operations. A dual oil seal and cover prevents coolant seepage into the workhead
  • The design of the tailstock is both rigid and robust. Housed is a cast body, the hardened Nitrally steel sleeve is designed to carry a MT4 center
  • Optional hydraulic tailstock with food pedal is available for easy loading and unloading.
  • Cartridge type wheel spindle is equipped with four super precision class 7 ( ABEC) bearings incorporated with 7.5 HP spindle motor ensure high accuracy.
  • 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.
  • A special upper slide design adds 180 mm ( 7”) in total wheelhead travel and increases grinding capacity.
  • Rigid table with box-type structure travel on a cushion of oil with no metal-to- metal contact.
  • Table is fully supported in the full travel to avoid overhang. A swiveling able dial indicator enables rapid cylindricity corrections and taper grinding applications.
  • Slideways, leadscrews are continuously lubricated by an auto –lube system to ensure long service life and maintain maximum accuracy.
  • The hinged, swing-down internal grinding attachment ( optional item) swinging down into working position easily and quickly.
  • A patented locking device adds safety as it prevents the ID attachment from swinging down abruptly.
  • 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, find increment, sparkout passes, feeding direction, parking position, retracting clearance and press cycle start to complete automatic grinding cycle.
  • Optional manual level 5C lever type collet closure for quick and precise holding of work piece
