Large, Heavy Duty Lapping Machines
For larger lapping applications Kemet offer machines with a 72", 84" or 120" plate.
Features & Benefits:
- Set within a mesh guard, a side mounted motor transmits the drive via multiple v-belts to a mechanical reduction gearbox at the center of a cruciform shaped steel structure.
- Four stations, the roller yokes mounted on hollow section upright columns at the end of each arm, which also support the trough around the lap plate.
- Electronic soft start to smooth accelerate the lap plate to full speed is time adjustable to suit individual process conditions.
- Suitable for use with conventional abrasive slurries or Kemet Diamond slurries.
- Free-standing conventional abrasive reservoir/stirrer/pump supplies four individually adjustable feeds to each of the stations.
- Electronic diamond dispenser and stirrer unit provides fully controlled metering of liquid diamond and lubricating fluid to each station, via dispensing bars and spray heads, to ensure even distribution and minimize consumable costs and waste.
- Water cooling option available

Designed for Diamond Lapping processes, these machines come equipped with liquid diamond dispensing, as well as conventional abrasive, systems and are fitted with a choice of Cast Iron or Kemet Composite Faced plate/segments.
