The machine tool adopts the German SIEMENS CNC system (other systems can be optionally equipped). The servo motors are all controlled by digital quantity, and the interpolation and linkage functions can be realized.
*The two axes are driven by servo motors to move the ball screws. The transmission chain is simple and reliable, and it can realize gap - free and high - sensitivity movement.
*The machine tool can be optionally equipped with hydraulic expansion fixtures, hydraulic power chucks and many other fixtures. The clamping precision is high and the workpiece loading and unloading are convenient.
*The work box adopts a high - precision sleeve spindle structure. The rotation of the headstock spindle is infinitely variable - speed regulated by an AC variable - frequency motor through a multi - wedge belt.
*The grinding wheel spindle adopts a high - power and high - rigidity electric spindle pulley, driven by a static frequency converter.
