2 1 The Application and Parts 3 Updated Machine Structure and SMT Options 9 Controller Selection 1 Performance Diagrams / Layout Dimension / Specifications Metal removal rate and good quality of surface finish are two main concerns when dealing with the high speed machining. The capability of high metal removal rate are based on well design of its structure, axes thrust force and spindle horse power and torque. Thus, spindle horse power and torque can be considered as the main variable factors while improvement of machining technology. A higher metal removable volume can be achieved while the high speed machining technology is applied. Quality of the surface finish can be affected by many factors, including chip load, tool geometry and inclination of the tool, etc. The benefit of high speed machining is that higher removal rates can be accomplished, a better tolerance can be achieved and the cutting time becomes shorter, in addition to high spindle speed, fast cutting feed, high acceleration/deceleration, and a high end CNC controller. However, risks of vibration and thermal expanse could occur due to high speed, the technique of mechatronics is a great effort to improve the reliability. The Application and Parts Investment for Future Competition in processing industry not only exists in developed countries but also in production line of emerging countries, the advantage of the location and low cost labor is no longer natural benefit. The global competition are threatened heavily because of shorten physical distances of transportation time and technology background. In this case, excellent performances of processing time and speed can provide higher benefit and longterm vantage for investors. Therefore, investing in new equipment with advanced features is absolutely a guarantee of better profit, which costs slight higher equipment expense but offers high reliability and efficiency.
