Basic Concept of High Speed Cutting in Precision Parts Processing
High speed cutting (HSM or HSC) in precision parts processing usually refers to end milling at high spindle speed and high feed speed. It is an advanced processing technology that quickly went to practical application in the 1990s, and has been widely used in aerospace manufacturing, mold processing, automobile parts processing, and precision parts processing.
Precision parts processing
High speed milling technology in precision parts processing can be used not only for free cutting metals such as aluminum alloy and copper, but also for difficult to machine materials such as quenched steel, titanium alloy and high temperature alloy, as well as non-metallic materials such as carbon fiber plastics. For example, in the processing of aircraft parts such as aluminum alloy, there are many curved surfaces and complex structures, and the amount of material removal is up to 90%~95%. High speed milling can greatly improve the production efficiency and processing accuracy. In mold processing, high-speed milling can process steel parts with a hardening hardness greater than HRC50. Therefore, in many cases, EDM and manual grinding can be omitted, and high-speed milling can be used after heat treatment to meet the requirements of part size, shape and surface roughness.
