Automatic End Hole Turning



  • Used for the synchronous processing of the spigot at both ends of the steel pipe.
  • The vertical and horizontal feeding of the tool is driven by hydraulic pressure, which produces smooth feeding with high precision.
  • The workpiece's clamping, positioning, tool feeding and withdrawing are automatically done in sequence with high productive efficiency.
