High speed processes the design of the machine tool and application
Tan Rumou

Machine tool of high speed treatment is the development that is based on material of contemporary cutting tool, the machine tool of efficient, high-powered treatment that the development that waits for an industry to satisfy aviation, spaceflight, car and mould needs and the development on the foundation in numerical control milling machine, machining center rises, accordingly, its main feature is cutting speed not only tall (the 5-10 that is groovy cutting speed times) , feed / move quickly rate is rapid (amount to 40m/min to 180m/min) , add decelerate to spend big (it is 1g~2g more now) , and return a bag to contain the time weak point that cutting tool is mixed or workpiece exchanges (come in several seconds 1 second less than) and often have function of much axis linkage to wait for a characteristic.

Because high speed machines a machine tool to have a lot of advantage, be like:

Manufacturing efficiency is tall, the 3~6 that material purify rate is machine tool of groovy cutting treatment times, can shorten greatly thereby the handling time of the spare parts and production cycle;

When cutting force compares groovy rate little 30%~50% peace treaty the heat in metal cutting of 30% above takes away place of the bits that be cut, so workpiece temperature rise is mixed be out of shape little, be helpful for undertaking Bao Bi cutting and raise treatment precision;

Because cutting rate is high, the forced oscillatory frequency to be far from machine tool machining complex commonly natural frequency of the generation in cutting process, reason cutting process is smoother, be helpful for improving treatment surface quality and cutting tool life, the artificial order that dismisses a lot of take time to take a lot of work works;

The component that place of a lot of mechanical and electrical products use, no matter be odd or of batch demand, can machine a machine tool in corresponding high speed (the high speed machining center that is like much axis linkage and car mill center) compound treatment holds order of aspirant travel multitask even clip realizes full treatment.

So, high speed machines a machine tool to go up oneself century since 80 time metaphase appears, get the attention with common people. As concerned technology, if high speed is electric main shaft, linear electric machinery, function the rapid development that wait mixes the numerical control servo with strong, good performance to be perfected increasingly, high speed processes the production of the machine tool and application, already became very general now; Not only the machine tool production manufacturer with big famous international can be produced, plant of general domestic and international machine tool also is beginning to make, and the dominant product that the try to be the first in becoming line of business of world machine tool develops, not only mould, the industry such as spaceflight, aviation is undertaking sheet or the application in pre production, also be in when undertaking batch is produced in car and even manufacturing industry of one flight tool use extensively, the mainstream in becoming these industries thereby machines equipment.
