Machine Shop: Non-conventional Machining Processes - OK ...
There are two main types of machine processes or procedures that are employed in manufacturing industries, namely conventional and non-conventional machining. Both have their pros and cons, and areas where they are more suitable than the other. What is Non-Conventional Machining? It is a special procedure that involves no direct contact between the …
What is Abrasive Machining?
To move grinding wheel speeds into the ultra-high speed grinding (UHSG) regime (above 40,000 fpm or 200 m/sec), the wheel core must be made of metal, and the abrasive is likely to be plated. Such wheels can run at nearsonic speeds (66,000 fpm or 335 m/sec) without the fear of bursting.
