GRINDING FEEDS AND SPEEDS

Dec 15, 2016Process Variables and their Effect on Grinding Wheel Performance Grinding wheel recommendations, unless prepared for specific cases, are predicated on conditions which may be considered as average. Deviations from such basic conditions will generally affect the manner in which grinding wheels actually act.

Grinding

A mechanical process using a rotating grinding wheel made from abrasive material containing small particles of grit ranging from fine to coarse. The wheel revolves around a central axis, making contact with the surface of the workpiece, while the particles act as cutting tools that cut chips from the material.

How grinding wheel is made

Grinding is a combination of rubbing, ploughing and cutting (actual chip formation) . A certain level of grit penetration into workpiece is required before chip formation can start. Magnitude of critical grit depth of cut required to initiate cutting becomes less with the increase of grinding velocity.

What is the Lapping and Define the Process

Home / About / Technology / What is Lapping? Define Lapping. What is 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.

What is the Lapping and Define the Process

A process to generate a reflective surface; Normally, the polish is generated by using a fine-micron or sub-micron abrasive particle in combination with a liquid. Polishing is a "wet" process. Often the polishing process utilizes a pad to contain the abrasive, so polishing may not be a "loose abrasive process." The pad is softer than the part.
