Main castings of the machine tool are cast with resin sand and wood patterns, and undergo two aging treatments, ensuring stable structure.
The castings adopt a box – type structure, optimized by finite element method, with good rigidity.
The three – axis feeding system adopts direct – drive connection and pretension stretching installation.
A high – power, large – torque spindle motor is used, with strong cutting capability.
A large – cross – section square ram (500×500mm or 600×600mm available for selection) is adopted, enabling strong cutting.
A direct – drive spindle with ZF two – speed precision reducer from Germany is used, allowing high – speed and high – strength cutting.
