Dear Labnetwork,
  I am looking for a 4" polishing head for a Westech 372 that I could
purchase or borrow for the machine set up and calibration. I have a 6"
head currently but to ensure correct alignment and assembly I need a 4"
head to prevent wedging (polishing one side of the wafer more than the
opposite side) during 4" processing.
  Please return e-mail or phone (716) 475-6526 if you can help me with
this. We are working on the purchase of a new one but won't receive
before the installer arrives.
  Thank you for your help,
  Sincerely,
  Bruce E. Tolleson
