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. Outlets are provided to feed each conditioning ring via a track wire, with individual control valves. 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. Excess compound is returned to the reservoir via a sloping drain tube. This together with the constant agitations provided by the stirrer minimises the tendency of the abrasive grains to settle out in the vehicle. 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 steel base. The mechanical reduction gearbox is mounted at the centre of the base, with thedrive motor to one side. Drive is transmitted via multiple vee belts, 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 pneumatic lift version. See appropriate datasheet, available on request.
