  • *Linear and Rotary magazine must use air chuck (3R-600, EROWA).
  • **When variation of the AC power source is +15% over or -10% under, we recommend using AVR to improve stability.
  • ***The relationship between machining area and surface roughness of HQSP is: 50Ø (Ra 0.15µm), 400cm² (Ra 0.25µm).
