Without CE mark, only for export to countries outside the EU

The RSM NC is a high precision cylindrical grinder designed especially for long and heavy workpieces. Instead of the conventional Hydraulic Unit, this model features a modern servo motor drive for both axes, which brings the dynamics, efficiency and precision of this machine to a new level. This machine is ideal for single parts and small batch productions, and the integrated inside grinder adds flexibility. The solid construction with a large machine bed, ground guideways and powerful drives for work spindle and grinding spindle has a proven record. Advanced NC control with touchscreen requires no previous programming knowledge, simplifies operation and increases productivity.

  • NC control with touchscreen
  • Grinding cycles for internal and external cylindrical grinding
  • Servomotors in both axes

Machine bed

  • The heavy machine bed is designed for high-precision machining of large and heavy workpieces
  • The swiveling work table runs on precision-ground, wide and long v-block guides ensuring excellent vibration damping
  • With this design the total weight of table and workpiece is distributed evenly over a large area, which ensures high rigidity and minimal tilting torque
  • The robust tailstock ensures rigidity and accuracy during clamping of a workpiece between centers

Feed

  • The use of servo-conventional feed technology instead of a hydraulic system results in a more consistent and vibration-free advance of the work table
  • Premium servo drives allow axis movements with the precision and dynamics of modern CNC machines
  • All feed settings can be set with high accuracy and repeatability, and electronic stop gauges provide precise travel limits
  • Preloaded ball screws on all axes ensure reduced friction and significantly lower breakaway torques resulting in faster and more precise movements
  • The significantly reduced heat build-up leads to more consistent conditions during continuous operation and long-term wear reduction
  • Drives, spindles, and measuring systems are totally enclosed or mounted in protective enclosures and virtually maintenance-free

Grinding Headstock

  • The headstock runs on premium linear guides that allow maximum positioning accuracy even at the slightest axis movements
  • An extensively supported grinding spindle guarantees maximum precision and surface quality for roughing and finishing work
  • The inside grinder can be pivoted into the work area as needed and is driven by a separate motor

Work spindle drive

  • The work spindle headstock swivels to one side, and the spindle speed is infinitely variable
  • A 3-jaw chuck with 7.9" diameter and superior concentricity is included in this series’ standard equipment

Equipment

  • The work area features large doors for easy access and easy loading and unloading
  • All controls are arranged conveniently on two control panels
  • LED lights ensure good visibility and safety during machining operations
  • An automatic central lubrication system simplifies maintenance and reduces the operator's workload
  • Two electronic hand-wheels (one at each control panel) simplify machine setup and reduce down times
  • A rest for machining of long workpieces is included in the machine’s standard equipment
  • A powerful coolant system, dresser, grinding wheel balancer, and operating tools also are included in the standard package
  • Technical parameters are displayed on a large touch screen monitor

NC control

  • The NC positioning control allows the combination of roughing, finishing and spark-out in one operation
  • Individual grinding cycles can be programmed via a touchscreen control, no programming knowledge required
  • The HMI provides easy to use control menus for every longitudinal and traverse cylindrical grinding application
  • Detailed graphics assist the user during data entry and show the current status during machining operations
