Roller type linear ways on three axes

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

Highly rigid 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 ballscrews. 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 head 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 of machine is manufactured from high durability cast iron (FC-300), and they are assembled after high precision grinding and scraping.
