Main Features
- Adopt a high-rigidity straight-rolling guide slot featured in high moving speed and high positioning accuracy.
- Capable of high-precision milling of straight lines and arcs at any angle, and drilling and tapping as well.
- Tool-change systems can change tools at high speed and in the shortest route.
- AC servo spindle motor needs no maintenance of changing electric
brush but can select the optimum cutting speed at your will. - The servo unit includes three feed axis, No.4 axis (when No.4 axis is equipped), control drive part of spindle, which are all located in the electric cabinet.
- Fully utilize electric technique to simplify mechanic structure and replace hydraulic transmission, so as to improve reliability and facilitate maintenance.
- Standard disposition provides rich NC functions, such as: LCD display, various cyclic function, tool compensation, program memory and edition, alternation between metric system and British system, etc.
- Basic parts (pedestal, bed, column, etc) of the machine are of synthetic resin cast, and have surpassed duration process. Rational structure design, perfect processing and assembling technology ensures strength, rigidity and precision keeping of the basic parts.
