Types and Characteristics of CNC machining centers commonly used tool
CNC machining center tools CNC machine tools must adapt to high-speed, high efficiency and high degree of automation features, generally include universal tool, universal connector and a small handle special shank. To join the tool shank and the head mounted on the machine power, and therefore has been gradually standardized and serialization. CNC tool free in many ways. According to the structure of the tool can be divided into: ① monolithic; ② mosaic, welding or machine clip-on connection, machine clip can be divided into two and translocation translocation can not; ③ special type, such as composite tools, Save shock-type tool. Folding tool according to materials used by manufacturers of CNC machining centers can be divided into: ① high-speed steel cutting tools; ② carbide cutting tools; ③ diamond tools; ④ other materials, tools, such as cubic boron nitride cutting tools, ceramic cutting tools. From the cutting process can be divided into: ① turning tools, exceptionally round, bore, thread, and other cutting tools; ② drilling tools, including drills, reamers, taps, etc; ③ boring tools; ④ milling tools, etc. . In order to adapt the tool CNC machine tools durable, stable, easy to tune, and other requirements can be changed in recent years, machine clip indexable cutting tools are widely used in the number of 30% to 40% of the CNC tool, metal removal It accounted for 80% to 90% of the total.
CNC tool compared with the general machine tools used tools, there are many different requirements, mainly has the following characteristics:
⑴ rigidity (especially roughing tool), high precision, anti-vibration and thermal deformation;
⑵ interchangeability for quick tool change;
⑶ high life, cutting performance is stable and reliable;
⑷ easy to adjust the size of the tool to reduce tool change time to adjust;
⑸ tool should be able to reliably breaker or volume chips to facilitate chip exclusion;
⑹ serialization and standardization, in order to facilitate programming and tool management.
