Lapmaster Model 84 Pneumatic Lift 4 Ring

The Lapmaster Wolters Model 84 is equipped with a 2134mm diameter lap plate. This is manufactured from Grade 300 grey cast iron to ISO 185(2005). It consists of individual segments bolted to a support plate. Pressure weights are attached through self aligning bearings to the rods of the pneumatic cylinders. The cylinders are mounted on a framework located over the lap plate on two upright columns. As this machine has no worktable, the roller yokes can be adjusted vertically as well as laterally, so that the normal wearing of the plate during prolonged usage can be accommodated. The machine is intended for use with free abrasive compounds. A diamond dispensing system can also be fitted. Flatness of the lap plate, and consequently of the work, is controlled by adjusting the position of the conditioning rings relative to the lap plate track. The model 84 uses a cruciform shaped structural cast iron base. The mechanical reduction gearbox is mounted at the centre of the base, with thedrive motor to one side. Drive is transmitted via a multi-vee belt, and the moving parts of the system are enclosed within a mesh guard. At the end of each arm of the cross are mounted hollow section upright columns. These columns support the trough surrounding the lap plate and provide the mounting point for each of the four roller yokes. This machine is also available in a open face version.
