Kemet Spherical Lapping and Polishing Machine

Kemet Spherical Lapping and Polishing Machine

Current buffing processes used to polish spherical balls and cups can detrimentally effect the roundness. Current machines used to polish spherical balls and cups have between 10-20% failure rate. The machine and process developed at Kemet International produces a mirror polish, holds geometry and can correct these failures while maintaining roundness down to 2 microns. The whole process takes less than 9 minutes.

The system can be used on most materials including ceramic, natural metals and alloyed metals. Applications include

  • Prosthetic Devices
  • Bearing Manufacture
  • Valve assemblies
  • Pump Components

There are only 2 steps to obtain a mirror polish starting with a machine ground spherical ball or cup. These are:-

  • Lapping stage
  • Polishing Stage

Machine features

  • 6 motors all with independent variable speed to provide complete control.
  • Lapping and Polishing pressures applied pneumatically.
  • Simple change from ball to cup polishing action.
  • Low running costs.
  • Average process time less than 9 minutes.
  • CE marked.

Advantages

  • Able to process all common materials including Stellite, Ceramic and Cobalt Chrome.
  • Simple fixture designs to accommodate all styles of product.
  • All critical parts manufactured from stainless steel.
  • Modular design to enable easy configuration of manufacturing cell (Eg 2 x polishing stations or 2 x lapping stations).
  • Dedicated approved consumable formulations to give consistent repeatability.
  • Built in cleaning option between stages.

 

Why Should you choose a Kemet Spherical Polishing system?

  • Proven and established technology.
  • No more buffing by hand.
  • Able to correct failures produced by other Spherical polishing machines.
  • Superior mirror polish is achieved.
  • Kemet machines hold geometry and achieve roundness better than 2 Microns.
  • Able to process common materials such as Stellite, Ceramic and Cobalt Chrome.

Kemet Diamond Dispensing Systems

 

Kemet Diamond Dispensing Systems

Kemet Electronic Dispenser
Converts your Flat Lapping Machine to a Kemet Diamond Lapping Process.

Has fully automatic independent control of both Kemet Liquid Diamond and Lubricating Fluid by means of touch sensitive settings. The digital display is easy to read and shows dispensing intervals, durations and air pressure at a glance. Dispensing is achieved to an accuracy of 0.2 gram eliminating wastage, making costs simple to calculate.

Kemet Liquid Diamond Stirrer Unit
Maintains a consistent distribution of Diamond particles within the Slurry by using a small non-contaminant plastic coated paddle magnet which is immersed in the Liquid Diamond. When the Stirrer Unit is in operation, the paddle rotates at a preselected rate ensuring even Diamond Suspension.

Kemet Dual Dispensing Bar
Can be positioned to accurately dispense Liquid Diamond and Lubricating Fluid on to the Lapping Plate without spray bounce.
