PL-1224/1632NC Series

High Precision Surface Grinder (Saddle Type)

Specification:

  • All essential castings are rib reinforced to provide a rigid machine structure for long lasting accuracy and stability.
  • The precision cartridge spindle equipped with 4 pieces of preloaded class 7 (p4) super precision angular contact ball bearings to ensure high accuracy and superior grinding finish.
  • Spindle, couplings, and spindle motor (5HP) are precisely balanced for low vibration and powerful output to achieve precision grinding accuracy.
  • Rigid table with box-type structure travels on a cushion of oil with no metal-to-metal contact to provide excellent way longevity.
  • Column guideways are Turcite-B coated and precisely hand scraped to provide a smooth movement for better accuracy and longer way life.
  • The rigid wheelhead travels on wide contact hardened and ground guideways and is precisely positioned with a stepping motor to ensure better downfeed repeatability.
  • Crossfeed mechanism incorporate with a precision ball screw, AC inverter provides smooth accurate crossfeed and allows criss-cross grinding for better grinding surface finish.
  • Hydraulic, coolant and lubrication systems are separated from machine to eliminate vibration and dissipate heat. Heat exchange is used on hydraulic system to maintain normal temperature of hydraulic oil.
  • All moving surfaces and rotating parts are continuously lubricated by an auto-lube system to ensure long service life and maintain maximum accuracy. An alarm light will illuminate if oil pressure drops below present pressure.
  • PLC control uses a menu-driven color 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, wheelhead retract distance, and press cycle start to complete automatic grinding cycle. (NC model only).
  • Positioning accuracy and repeatability is assured with an AC servo motor and High Precision pre-tensioned ballscrew. (CNC model only)
