  • Page 21 GENERAL When the deep hole cutting is executed by the tapping cycle or the rigid tapping cycle, the cutting may be difficult because that the chips gets entangled in tool or the cutting resistance increases. In this case, this function, such that the cutting is performed by moving from point R unt
  • Page 32 SPECIFICATION When the parameter PCT (No.5104#6) is set to 1, this function is available. By setting the parameter PCP (No.5200#5), the tapping cycle type (high-speed peak tapping cycle or peak tapping cycle) is selected. And set return value (at high-speed peak tapping cycle) or clearance (cuttin
