speed lapp leppelö lapka

The speed lap system comprises of pads and bars for applying diamond  compounds in order to obtain high surface quality while saving time.

• New composite material
• Prevents the washing out of soft constituents and the formation of built-up edges
• Higher material removal rate (compared to other lapping techniques)
• Less sensitive to pressure
• Enables consistent, scratch-free lapping
• Sturdy lapping bars

Technical information

• Preparing the lapping pads:
  Before using the lapping pads for the first time, use a fine abrasive paper or diamond foil to hone them.
• Preparing the lapping bars:
  Adjust the lapping bars to the shape of the surface on which you are going to use them; this can be done with sanding discs, abrasive paper or files. You can use a collet to hold circular lapping bars.
• Grit:
  The optimum grit size is 6 μm but you can also use a coarser grain structure. If required, you can lap to 3 μm.
• Lubrication:
  You can use VLM 5 Cutting fluid or VLM 20 Polishing oil for thinning the diamond compound.
• Pressure:
  For 60–70% of this work step, apply light pressure; for the rest of the time, that is: for finishing, do not apply any pressure.
• Hand-filing machine:
  Speed: 4.000-7.000 min^-1
  Stroke length: 0.5-1.0 mm
