]]> The Servogrind® RSM NC is a precision cylindrical grinding machine for long and heavy workpieces. Instead of a conventional hydraulic unit, however, the series has a modern servo motor drive for both axes, which raises the dynamics, efficiency and precision of the machine to a new level. The series is suitable for both single part and small batch production and offers additional flexibility with the internal grinding device. The solid construction with a large machine bed, ground guideways and powerful drives for the work spindle and grinding spindle has proven itself many times over. The modern NC control with touchscreen requires no programming knowledge, simplifies operation and increases productivity.

  • NC control with touchscreen
  • Grinding cycles for internal and external cylindrical grinding
  • Servomotors in both axes
  • Swivelling table and swivelling work spindle
  • Extensive range of standard accessories
Center height 180 mm
Working spindle taper 4 MT
Grinding length 1000 – 1500 mm
Workpiece weight between centers (max.) 150 kg
Grinding diameter 8 – 320 mm
Grinding wheel dimensions 400 x 50 x 127 –
400 x 50 x 203 mm

]]> The special construction of the Multi Grind makes it possible to combine the functions of cylindrical, flat and tool grinding in one machine. With external cylindrical grinding, the workpiece is either clamped on one side or supported between centers in the stable tailstock. An internal grinding device can also be attached to the headstock and light surface grinding work is also possible with this model. With the additional tool grinding function area, you can use the Multi Grind to machine the cutting edges of a large number of tools.

    • Outer and inner cylindrical grinding
    • Surface grinding
    • Tool grinding
    • Hydraulic table feed

]]> The machine frames of the RSM series are characterized by a heavy design and long, supporting guideways. The table can be swiveled and the finely adjustable hydraulic feed moves smoothly in the longitudinal direction. A large scale ring on the handwheel of the X-axis facilitates precise infeed and the zero stop guarantees compliance with the desired dimension. The standard position indicator with linear scales is used to check the actual values. The headstock is rotated 180 degrees for internal grinding. An extensive accessory package is standard.

  • Internal and external grinding
  • Hydrostatic bearings for high surface quality
  • Swiveling headstock for conical grinding of short parts
  • Integrated rapid feed on Z-axis with manual return
