Micro-machining | Philosophical Transactions of the Royal,
28-08-2012· Mechanical micro-machining is further subdivided into cutting and abrasive machining, with the latter comprising precision grinding and polishing and the former being dominated by diamond turning and milling. Figure 1. Classification ofThe Glass Surface and Ways of Its Modification,Usual techniques are grinding, polishing and blasting. Mechanically ablated surfaces always become rough,, Micro-cracks are suspected to weaken the mechanical strength of the part. On the other hand, surface frosting by blasting is typically cheaper than by etching.What is the Lapping and Define the Process?,Define 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.,,,
