Lapmaster Model 56 Open Face 4 Ring

The Lapmaster Wolters model 56 is equipped with a 1422mm 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. This system is designed so that a circulatory flow is established. The pump is capable of delivering far more compound to the outlets than is necessary. Excess compound is returned to the reservoir via a sloping drain tube. This together with the constant agitations provided by the stirrer minimizes the tendency of the abrasive grains to settle out in the vehicle. The machine is intended for use with free abrasive compounds. A dispensing system, for use with water and diamond compounds etc., can also be fitted. Flatness of the machines lap plate, and consequently of the work, is controlled by adjusting the position of the conditioning rings relative to the lap plate track. The lapping plate drive system uses a separate motor and worm & wheel mechanical reduction gearbox with multi-belt drive, and is mounted in a floor standing base. This base is a fabricated steel channel framework with removable panels for ease of access during maintenance. The drive system incorporates an electronic soft start which will smoothly accelerate the lap plate from standstill to full speed over a controlled time period. This is preset, though can be adjusted if required, to suit particular process conditions. This machine is also available in a pneumatic lift version. A datasheet is available on request.
