Lapmaster LLCD — плоско-доводочное оборудование

Designated the LLCD series, a typical machine consists of a heavy duty, structural steel base housing a drive system linked to a lapping plate. A polishing pad (type dependent on material to be processed) is bonded directly to the plate.

A swing arm assembly positioned above the polishing surface is mounted to a swivel head workpiece pressure plate. Workpieces of varying geometries can be retained by surface tension, wax or vacuum to the pressure plate. The pressure plate is designed to swivel up from the horizontal position to facilitate load and unload operations.

Adjustable stroke on the swing arm assembly enables the pressure plate to sweep across the polishing surface. This unique combination of rotating polishing plate and oscillating workpiece movement ensures:

  • Maximum utilization of the polishing surface
  • Suppression and elimination of «tracking» effects on the polishing surface
  • Improved control of polishing surface flatness
  • Precise optical flatness control of workpiece

The LLCD series of machines are used for processing a wide variety of materials in an extensive range of industries:

  • L.C.D.faceplates
  • Silicon Wafers
  • I.C. Photomasks
  • Crystalline substrates (Sapphire, Gadolinium Gallium Garnet-GGG)
  • Ceramics
  • Ferrites
  • Filterglasses

The equipment is particularly useful for polishing single, and large area glass substrates. Lapmaster offers five basic machines with polishing plates varying in size from 600 mm to 1000 mm diameter. Single workpieces ranging from 480 mm to 780 mm diameter can be accommodated.
