Lapping Machines
It is a double-sided lapping machine, which works on the same principle as fine grinding using lapping kinematics. It has one top lapping wheel and two bottom lapping wheels, each having their own belt for speed adjustment. This machine is an SP3 model, of type 210-3P made in 1995 and it weighs 500 kg. It can handle pressures between 22 and 63 kg.

The Technique of Lapping
Grit size and Surface Finish. As an example, on a steel part hardened to 60 HRc, lapped using silicon carbide 500 grit, a pressure of 250 g/cm squared will produce a surface finish of about Ra= 0.2 my (N4) or Rz 0.6-0.8, whereas by reducing the pressure to 50 g/cm squared, a surface finish of about Ra= 0.05 my (N2) or Rz 0.2-0.3 can be obtained.
Why Use a Surface Finish Chart? | Metal Surface Finish
If a customer's requirement is different than the raw material's "as drawn" surface, Metal Cutting can grind the material to achieve desired results for a part's diameter surfaces (or the body of the part). We typically achieve 8 to 16 µin Ra through grinding, but 2 to 4 µin Ra is possible under certain circumstances.

Honing, Lapping, and Super-finishing Machines Information
Lapping generates flat surfaces (geometry refinement) with extremely fine finishes using lapping compound, where parts are processed between one or two large flat lap plates or platens. Lapping is a gentle surfacing process using low speeds (80 RPM) and low pressures. Compared to grinding and honing, lapping removes much less material.

Abrasive Material | SpringerLink
A typical range of surface roughness that can be obtained without resort to special equipment would fall in the range of 1–30 Ra. High-speed lapping, also known as fine grinding or flat honing, uses a fixed abrasive wheel in place of the wet slurry. This dramatically reduces the lengthy cleaning process and eliminates grit impregnation.
