What it is

The Lapmaster 36 is a floor-standing single-sided lapping and polishing machine. The machine is designated as Model 36 by Lapmaster. The machine features a pneumatic lift version of the Open Face design. Three conditioning rings are mounted above the lap plate. The lap plate has an outer diameter of 36 inches (914 mm) and an inner diameter of 6.75 inches (172 mm). The drive motor is rated at 4 kW (5 HP) and provides a standard lap plate speed of 58 rpm. The machine weighs 1202 kg (2650 lbs) with a shipping weight of 1383 kg (3050 lbs). Power supply is 230 V or 460 V, three-phase, 60 Hz.[1][3][4]

How it works

The Lapmaster 36 operates on an Open Face design with a pneumatic lift system. Pressure weights are attached to the rods of three pneumatic cylinders mounted on sliding rails within a spider bar cantilevered over the lap plate. The machine uses three conditioning rings to control flatness of the lap plate. The pneumatic system allows loading and unloading without manual lifting of weights. Operator safety is addressed with a two-hand anti-tie down control system that requires both hands on two separate buttons to lower the weights. When fully raised, the pressure weights are mechanically latched to prevent falling in case of power or air failure. The machine is intended for use with free abrasive slurries and can be fitted with a diamond slurry dispensing system.[4]

Applications

The Lapmaster 36 is designed for use with free abrasive slurries, with abrasive grit suspended in an oil-based or water-based vehicle. A diamond slurry dispensing system can be optionally fitted for polishing hard materials.[4]
