A kind of column and knee type machining tool
Technical field
This utility model relates to a kind of processing unit (plant), specifically a kind of column and knee type machining tool.
Background technology
Milling machine refers mainly to the lathe using milling cutter to process kinds of surface on workpiece, generally milling cutter rotary motion is main motion, the movement of workpiece and milling cutter is feed motion, milling machine can process plane, groove, various curved surface, gear etc. can also be processed, can also process more complicated profile, efficiency relatively planer is high, is used widely in machine-building and repairing department.Along with the development of science and technology, people investigated CNC milling machine, uses the work process of program-control milling machine, and milling machine can be divided into column and knee type milling machine, the desk-top milling machine of planer-type milling machine, not lifting work, watchmaker's milling machine etc..Column and knee type CNC milling machine is a kind of milling machine that people commonly use, although existing column and knee type CNC milling machine meets the use demand of people, but the main axle structure of existing CNC milling machine is thin and rotating speed is low;There is no tool striking device on main shaft, can only manual tool changing, elapsed time is long;Motor passes through tower-shaped belt pulley, it is necessary to the manual change speed of mainshaft, and not only efficiency is low, and changes trouble;Before and after workbench, bilateral reciprocation is to be supported by hard rail, and coefficient of friction is big, and workbench is difficult to the most mobile and the service life of workbench is short, and therefore, existing CNC milling machine is difficult to meet at a high speed and the market demands of high-efficient cutting processing.
