  • The pneumatic lift version of the Lapmaster Model 36 is based on the Open Face design, but the pressure weights are attached, through selfaligning bearings, to the rods of three pneumatic cylinders. These are mounted vertically on sliding rails within a fabricated hollow assembly, known as a “spider bar”. This fabrication is cantilevered over the lap plate and is mounted onto a tubular upright column bolted to the machine frame. The free end is restrained by a tierod to prevent excessive bending stress when high lapping pressures are used.
  • The primary function of the pneumatic arrangement is to permit loading and unloading to be carried out without the need to lift pressure weights manually. However they can be used to supply additional loading to the components within the conditioning ring should this be required.
  • Operator safety is a primary concern in the design. Movement of each pressure weight up or down is controlled by a two hand anti-tie down control system. This arrangement requires the use of both hands on two separate buttons to function and ensures that the operator cannot injure his hands or arms when lowering the weights.
  • A further safety feature is that the pressure weights are mechanically latched when in the fully raised position so that, should the compressed air supply or electrical power fail, they will not fall.
  • The machine is intended for use with free abrasive slurries - abrasive grit suspended in an oil-based or water based vehicle. A diamond slurry dispensing system can also be fitted if required.
  • Flatness of the lap plate, and consequently of the work, is controlled by adjusting the position of the three conditioning rings relative to the lap plate track. The pneumatic cylinders and pressure weights are also capable of the corresponding adjustment.
  • This machine is also available in Open Face version.
