This series of machine features optimal cost-to-performance ration. Every model among this series has a modular design and an enhanced mechanical structure, exhibiting high speed, high precision cutting performance and upgraded machine stability. Each model can fully satisfy the requirements for precise complex surface machining and mold machining in various industries. This SDC series can be widely applied to the high-tech industries, such as: aerospace, automotive and motorcycle, energy, electronics and transportation.

A. Roller-type linear guideways on three axes
● All three axes are mounted with roller-type linear ways. The X-axis (table) uses #55 linear guideways with 6 blocks. The Y/Z axes use #55 linear guideways. The Y-axis linear guideways are of heavy-duty type with rigidity increased by 70%, making the machine suitable for high-speed, high-rigid and long-term machining.

B. High-rigidity machine structure
● The massive base is a box type structure in combination with internal rib reinforcement. Employs 55mm high rigidity roller type linear ways and one grade increased Ø63mm ballscrew. These provide a dependable foundation to ensure high accuracy in high-speed machining.
● The oversized columns are of honeycomb structure with higher stability than others. This also provides better geometric accuracy maintaining capacity compared to conventional structures. The columns and the cross beam are one-piece fabricated. The contact surfaces of all parts have been scraped for higher accuracy of the machine, which in turn provides the best dynamic and static rigidity.
● The joint parts among the saddle, spindle headstock and cross beam are of stepped structure (top/side) design, which helps to boost stability when the Y axis moves at a high speed, reducing vibration and tilting forward to enhance the high-speed cutting rigidity of the spindle. This results in higher machining accuracy.
● All machine parts are subjected to analyze by using the Finite Element Method (FEM), which provides a light configuration after assembling, while ensuring the optimal rigidity of the machine.
● The table is a box-type structure with rib reinforcement to increase loading stability and machining accuracy.
● The series is manufactured from high durability cast iron (FC-300), and they are assembled after high-precision grinding and scraping.

C. Built-in Type Spindle with High Power
● Equipped with 10Krpm BT50 direct-drive spindle as standard
● The high-speed, high-rigidity spindle is suitable for high-speed and high-precision machining requirements on Die&Mold.
● The spindle is supported by high-precision, large ceramic bearings, providing outstanding axial and radial cutting rigidity (direct-drive type).
● The powerful built-in type spindle 20Krpm provides power output of 15/18.5 kw and max. torque of 118 Nm.

D. Saddle Support Adopts Stepped Design
● The saddle, headstock and beam are combined with a stepped design to enhance the stability of Y-axis rapid movement, reduce vibration forward tilt and strengthen the rigidity of the spindle for high-speed cutting, thereby improving the machining accuracy of the machine.

E. Box Structure Base Design
● Strengthen the arrangement of internal ribs, use 55mm high rigidity roller rails, and increase the level of Ø63mm ball screw at the same time. Provide a reliable foundation to ensure the accuracy of highspeed machining.

F. Honeycomb Structure Design
● The integrated casting structure design of columns and beams, and the contact surfaces of all components are manually scraped to ensure the accuracy of the machine and provide the best performance of dynamic and static rigidity.
