The diamond tool is commonly used in micro-machining as it can withstand the micro hardening of the workpiece surface during micro-machining. This micro-hardening creates enough resistance to break the tool bit easily in micro milling, but not a diamond tool. Micro-machining using diamond tool could be performed at high speeds and generally fine speeds to [...]

Stainless steel machining refers to the process of cutting steel sheets or bars into predetermined shapes for use as components in various industries such as aerospace, automotive, shipping, and others. Stainless steel machining can be done either manually or with the help of automatic machining systems combined with computer aided design (CAD) software.
Manual machining is [...]
