  • The Lapmaster Model 56 machine is an uprated version of the Model 48, with a larger diameter lap plate and support plate and correspondingly larger conditioning rings.
  • The serrated lap plate is made up of twenty four individual segments which are bolted to the support plate.
  • The height of the surrounding worktable can be adjusted so that it can be set just above the lap plate surface to prevent the sharp edge being exposed.
  • The lap plate drive system uses a separate motor and worm and wheel reduction gearbox with multibelt drive and is mounted in a substantial floor standing base. The base is fabricated from welded hollow-section steel, clad with removable panels for maintenance. The electrical controls are housed in a console mounted at the front of the machine, and a second emergency stop button is fitted at the rear of the machine.
  • The machine uses a free abrasive slurry, which is supplied from a separate free standing reservoir, equipped with a pump and driven blade stirrer. A diamond slurry dispensing system can also be fitted if required.
  • This machine is also available in pneumatic lift version and as an open face machine with three special size conditioning rings.
