Diamond / CBN Double Side Lapping Machine

Product Detail Information


  1. Use of fixed pellet allows "high precision", "even grinding on both sides", "processing", "little warping". Increased stock removal rate reduces the process time.
  2. No abrasive, so there is no worry about damaging the work enviroment.
  3. Workpiece with holes or dents can be processed without a hitch.
  4. More economical than abrasive machines since there is less wear on the carrier, internal gear and sun gear.
  5. Workpieces are easily cleaned, speeding up movement to the next process.
  6. Water soluble grinding fluid is used, so sludge can be processed with a centrifuge, improving the work environment in comparision to free abrasive lapping
  7. Automatic pressure conversion sytem(first stage, second stage, third stage)used. All you have to do is set the time and pressure for each stage for simple rough, intermediate and finishing processing.
  8. Automatic numerical thickness controller can process within tolerance of 0.005mm even when the thickness of workpieces are different.
  9. The upper plate is raised and lowered automatically with an air cylinder, so there is no need to worry about breakage even with thin workpiece. Mis-chucking can be verified from the digital reabout, making it easy for anyone to the unit.
  10. Safety devices prevent the upper plate from falling, keeping safet first at all time.
  11. The load cell has been installed to watch the present pressure for high efficient process.
