1. Linear electric machinery is linear electric machinery is to show one kind uses electromagnetism action principle, electric energy direct changeover becomes the actuating device of sharp movement kinetic energy, it is a kind of electromotor that can realize move back and forth to move point-blank. Exceeding high speed processing technique and nicety to make a technology is the advanced production technology that rises abruptly quickly nearly ten years, this technology can improve manufacturing efficiency and the treatment quality that improve a spare parts greatly. But the drive system that the application of this technology equips to treatment raised taller requirement, ask to have higher drive rate not only namely (like) of above of 60m ／ Min, and have taller acceleration even () of the above that be like 2g, and traditional " rotate electric machinery + ball guide screw " feed drive kind moves in high speed when, the dynamic function such as the stiffness of ball guide screw, inertial, acceleration already cannot satisfy a requirement far. This makes a kind of brand-new feed drive means -- emerge as the times require of system of control of linear electric machinery. System of drive of this kind of feed cancelled to arrive from dynamical source carry out a link of all the transmission intermediate between, shorten the length of feed drive catenary for 0, simplified greatly rigid structure, the dynamic character such as the rate that raised a system, acceleration, stiffness and control precision, it is a design of drive of machine tool feed is academic major breakthrough. 2. Main shaft of report of electric main shaft is the is machine tool main shaft and be in harmony of main shaft electric machinery an organic whole new technology that the last few years appears in domain of numerical control machine tool. Technology of it and technology of linear electric machinery, high speed cutting tool together, high speed treatment is promoted to a new era. Electric main shaft is a component, it includes itself of electric main shaft and its accessory: Device of high frequency frequency conversion, oily mist is lubricant implement, cooling device, inside buy coder and the device that change a knife. The technology of confluence of place of electric main shaft has: Technology of high speed bearing (if bearing of compound pottery and porcelain, electromagnetism hangs float bearing) , technology of high speed electric machinery (like high speed dynamic balancing) , the outfit of lubricant technology, cooling technology and high speed cutting tool places time and mensurable oil gas the technology.
