- Adopt a new type of reinforced bed, which has good load-bearing capacity and rigidity. Through finite element simulation design, it is endowed with an excellent structure against moment and vibration resistance.
- The guide rails are subjected to quenching and tempering treatment and then ground by a high-precision grinding machine, with good feed precision and shock resistance.
- The grinding wheel feed shaft and the worktable reciprocating shaft adopt the form that AC servo motors directly drive high-precision ball screws through reducers and couplings.
- The system can be optionally equipped with multiple numerical control systems such as SIEMENS, FANUC, MITSUBISHI, GSK, and KND.
- The appearance of the machine tool is simple and elegant. It has a floor-standing fully enclosed shield and is provided with clear and visible windows.
