Three axes employ roller and ball type linear ways, exhibiting outstanding structural rigidity and machining stability. Three axes are transmitted by C5 grade precision ball screws and equipped with 1 µ Differential type precision linear scales and provide closed loop control. Applying Laser interferometer inspections during assembling. Mirror Finish circuit is equipped as standard. Special circuit design for fast cutting tungsten carbide is available.
Main Unit Features:
1. The structural parts are designed and analyzed by applying the advanced Finite Element Analysis(FEA).
2. Precision linear ways on all axis assures smooth movement and high accuracy.
3. All structural casting are made of FC-30 cast iron, tempered and stress relieved for deformation free performance.
4. High precision spindle assembly insures excellent eroding performance.
5. Table surface is hardened and precision ground, assuring high machining accuracy and long service life.
6. Three axes movements are transmitted by precision ball screws.
7. Three axes are driven by DC servo motor.
8. Three axes are equipped with 1 µ Linear scale for closed loop control.
9. Each machine is compensated by laser interferometer, ensuring position reliability and increasing machine efficiency.
