• OPERATING INSTRUCTION

• For Diamond Impregnated Scaife
• Clean the scaife with water.
• Mount the scaife on the machine spindle. Make
  sure that the scaife is not fixed with very high
  tightening torque. A gentle tightening is
  sufficient for the process. A very high
  tightening Force can result in distortion of
  scaife.
• Place the lapping ring on the scaife, with
  lapping serration (slots) facing the scaife.
• Switch ON the lapping machine. The Scaife, along
  with the lapping ring will start rotating.
• Apply a small amount of lapping media to start
  lapping action. Keep watching the scaife surface
  occasionally, to monitor the progress. Apply
  lapping media (paste), if required. Stop the
  process, if the surface of Scaife is found free
  of polishing lines. (The lapping process will
  last for 1 to 5 hours depending on the depth of
  damaging groove on the scaife).
• On finding the scaife surface reconditioned,
  remove the lapping ring, and the subsequently,
  the Scaife.
• Wash the scaife, with cleaning media.

  small surface cut on a lathe machine, keeping the
  cut surface parallel to the back surface.
• Mount the scaife on the machine spindle. Make
  sure that the scaife is not fixed with very high
  tightening torque. A gentle tightening is
  sufficient for the process.

  process, if the surface of scaife is found free
  of polishing lines. (The lapping process will
  last for ½ to 1 hour depending on the depth of
  machining groove on the scaife and the concavity
  / convexity of the cut surface).
• On finding the scaife surface reconditioned,
  remove the lapping ring, and the subsequently,
  the Scaife.
• Wash the scaife, with cleaning media.
• Note It is necessary to carve / sand blasts the

• If in no position, the run out is within this
  permissible limit of 0.005 mm, the scaifes back
  face may be corrected,
• a. Either by grinding the back face, parallel
  to the front face on a grinding machine.
