BSM2 – CNC Curved Surface Grinding Machine

BSM2 – CNC Curved Surface Grinding Machine for workpieces with extremely curved surfaces. With up to 5 axis. The alternative to a grinding robot.


The BSM-CNC for optimal grinding of extremely curved surfaces (e.g. surgical scissors, side-cutting pliers, nippers or similar workpieces.

  • Pivoting around the vertical axis for extremely curved surfaces
  • Grinding of several surfaces in one clamping
  • The clamping block is bearing-mounted on one side and enables the complete all-round machining of the workpieces.
  • Short set up time (easy change of the workpiece supports and calling up the program)
  • PC-CNC control SINUMERIK 840D
  • Software DialogPLUS with automatic radius calculation


Optional features

  • Patent fixture block (for up to 4 different workpiece holders)
  • For extreme curves: Rotation with 5th CNC axis
  • Automatic feed and automation system with stackable, chain and cassette magazine
  • Technological support and immediate troubleshooting with Remote Support
