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.
Wide Application:* Die and mold industry * Automobile industry* Medical industry* General workshop* Aero space
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 long-term 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.

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.
New V-series Vertical Machining Center provides the technique of high speed machining technology. The combination of great performance high speed spindle, structure rigidity and latest powerful CNC produces a greater productivity and tolerance. An optional selection of high value package, the Smart Machining Technology (SMT) ensures the machine works better of the finish precision and faster of its cutting hour.

High speed machining equipment is not unique; however, the factors of high speed are not merely high-speed spindle, high feed rate and using high level CNC controller. Apart from the basic performances of spindle speed, feed rate and acceleration/deceleration, the reliability, stability and usability of equipment under its best condition are also crucial for providing time efficiency (no-waste-of-time) and the performance of accuracy. The new V-series Vertical Machining Center is not just a new machine providing the Smart Machining Technology (SMT); it is a great progress of the business!
