The box structure together with rugged base design is the basic requirement of the accurate machining.
To ensure thermal balance throughout the ribs’ allocation of a cast-iron of 5-axis, the reliability of rigidity is very high. The control monitors working temperature by means of thermal sensors on X, Y, Z-axis.
New ball-retainer linear guide has experienced in reducing of frictional vibration by 90%, together with a close-loop linear scale and quick response AC motor to reduce the influence of the backlash.

To achieve the desired precision, an extended distance between linear guide ways and a cryogenic treatment C1 class ball screws with supports of two sides and a high resolution AC servomotor are employed. These outstanding features boost accuracy of micro step motion up to 1µmm.
