    The Lapmaster Model 84 machine for standard duty applications is equipped with four work stations.
  • The machine includes a fabricated base assembly with segment support plate, splash trough and four equally spaced pillars. The four roller yokes and splash trough are mounted off pillars. The yokes can be positioned independently inboard or outboard for conditioning ring placement required to maintain a flat lap plate. The four conditioning rings are driven by the friction of the rotating lap plate and guided on the O.D. by the yokes and bearing assemblies.
  • A thirty gallon capacity floor standing slurry tank and pump assembly is included. The abrasive distribution system will have the continuous agitation feature which permits the pump to keep running after the lap plate times out. This insures that the abrasive is kept in proper suspension at all times even between lap cycles. Also included, is a four feed slurr y distribution feature which supplies a regulated flow of abrasive and vehicle equally to all four work stations on the lap plate.
  • Automatic timing device to permit setting a pre-determined lapping cycle for machine operation.
  • Non-hardened cast alloy segmental lapping plate 84” in diameter approximately 5” think. Also, four 35” O.D. x 32” I.D. 7” high non-hardened cast alloy conditioning ring assemblies with serrated and lapped conditioning surfaces.
  • One (1) Main Drive Motor, 40 H.P., 230/460 Volt, 60 cycle, 3 phase.
  • Special high torque gear reducer.
  • Electrical controls, 110 volt, single phase, 60 cycles actuated through a transformer for operation on 230 or 460 volts. Wired to National Electrical Code Standards unless otherwise specified.
  • Equipped with a power factor controller for energy conservation. Attachment automatically adjusts the drive motor voltage to meet the load requirements while maintaining full motor speed and torque availability. Also provides smooth, stepless acceleration through the gear reducer, reduces motor operating temperatures and eliminates sudden, high torque start up.
  • As an option, this machine can be equipped with a bridging support and pneumatic lift mechanism to raise and lower the concentrically grooved pressure plates and to provide additional down pressure. This equipment consists of an air cylinder mounted on each of the four stations. Each cylinder is individually controlled.
  • Four (4) micarta workholder blanks. 32” diameter x 1/2” thick.
