At present, high-speed cutting is no longer a technology in the laboratory, and it is more applicable to the following aspects.
1. Thin-walled processing of non-ferrous metals such as aluminum and aluminum alloys, especially aluminum. It is now possible to cut a formed curved surface having a thickness of 0.1 mm and a height of several tens of millimeters.
2. Graphite processing. In the cavity manufacturing of a mold, a graphite electrode is widely used because of spark erosion processing. However, graphite is very brittle, so high-speed cutting is required to perform the forming process well.
3. Machining of molds, especially hardened molds. Since the hardened material can be purchased directly from the supplier, the high-speed cutting can directly cut out the mold, which not only saves several processes of machining and electromachining in the past; saves man-hours, and also because of the current high-speed cutting High surface quality (Ra ≤ 0.4 um) has been achieved, thus eliminating the need for grinding and polishing after electromachining; on the contrary, the compressive stress state of the machined surface formed during cutting also increases the surface of the molded workpiece. The degree of wear resistance (there is a statistical analysis that the life of the mold can be increased by 3 to 5 times), so that it is possible to perform machining only by milling and forging.
4. Hard, difficult to cut materials, such as heat resistant stainless steel.
