Features

(1) The design adopts fixed beam gantry bed structure to ensure high rigidity, high precision, high efficiency and stability of the bed structure

The design adopts finite element analysis and dynamic optimization, which greatly improves the static and dynamic characteristics of each component of the machine tool to ensure the overall rigidity, stability and dynamic accuracy of the machine tool.

(2) Powerful high-rigidity and high-precision gear transmission turntable technology

The cradle-type rotary table is designed and manufactured by our company, and the AC shafts are all preloaded double-gear anti-backlash transmission, with super rigidity. In order to eliminate the first-order weak torsional mode of the cradle body, our patented torsional damper is specially designed.

· GTRT gear transmission turntable technology

· Evermi gear anti-backlash patented technology

· A/C turntable is supported by double arms, with high rigidity, strong bearing capacity and high precision

· DIN5 grade imported grinding gear technology

The applicability of a wide range of processing materials, including the processing of high hardness and toughness materials such as steel and titanium alloys

· A/C axis comes standard with HEIDENHAIN round light booth

· Chip removal. Easier to clean

· Creative Cradle Twist Yangni Technology
