Grinding basically is a machining operation; the cutting edges (that is, the grains) and chips are just smaller. Just as different cutting tools are designed for different applications, different grinding discs are designed for different metals. For instance, some welds in high-strength, abrasive-resistant steels have been known to be ground ...

What is Spherical Lapping? The term "lapping" is used to describe a number of various surface finishing operations where loose abrasive powders are used as the grinding agent at normally low speeds. It is a process reserved for products that demand very tight tolerances of flatness, parallelism, thickness or finish.

Tight tolerances of up to 0.0001" can be maintained in our grinding operations. Infeed Grinding Services. Infeed grinding is a method of grinding in which the part is held stationary while the wheel is fed into the workpiece. Infeed grinding is used to grind parts with relatively complex shapes with multiple diameters and tolerances.

The common grinding machine operation are surface, cylindrical, internal and centreless grinding. Now let us discuss each one by one, 1. Surface Grinding. It involves grinding flat surfaces. Here the workpiece is fitted with a magnetic chuck attached to a work table of the grinder. Non-magnetic are held by vices or fixtures.

Loose abrasive grinding uses inverse spheres of the same radii ground together so that the hills and valleys on the optics will wear away to produce a true sphere. Slurry flows in between the blocked parts and the spherical tool to keep the parts cool and wash away debris created during the grinding process.
