Cylindrical grinding machine

external cylindricalinternal cylindricalworkpiece

Product The Servogrind® RSM 1000 NC is a precision cylindrical grinding machine for long and heavy workpieces. It uses servo motor drives on both axes instead of a conventional hydraulic unit to improve dynamics, efficiency and accuracy. Designed for single-part and small-batch production, it includes an integrated internal grinding device and an NC touchscreen control to simplify operation and increase throughput.

Highlights

• NC touchscreen control with dedicated grinding cycles
• External and internal cylindrical grinding capability
• Servo drives on both axes
• Swivelling table and swivelling work spindle
• Comprehensive standard equipment package

Machine bed

• Heavy machine bed for high-precision machining of large, heavy workpieces
• Swivelling work table runs on precision-ground wide v-block guides for excellent vibration damping
• Design distributes table and workpiece weight over a large area for high rigidity and minimal tilting torque
• Robust tailstock provides rigidity and accuracy when clamping between centers

Feed

• Servo-conventional feed replaces hydraulic systems for smooth, vibration-free table advance
• High-performance servo drives give axis dynamics and accuracy comparable to modern CNC machines
• Precise, repeatable feed settings with electronic stops for exact travel limits
• Preloaded ball screws on all axes reduce friction and breakaway torque
• Reduced heat generation for stable conditions during continuous operation and less wear
• Drives, spindles and measuring systems are enclosed or protected for near maintenance-free operation

Grinding headstock

• Grinding head runs on premium linear guides for maximum positioning accuracy
• Robustly supported grinding spindle ensures precision and surface quality for roughing and finishing
• Inside grinding unit can be swung into the work area and is driven by a separate motor

Work spindle

• Work spindle headstock swivels to one side; spindle speed is infinitely variable
• 3-jaw chuck Ø 200 mm with good concentricity supplied as standard

Equipment

• Fully enclosed work area with large doors for easy loading/unloading
• Centralized controls with touchscreen HMI displaying technical parameters
• LED lighting for visibility and safety
• Automatic central lubrication system to simplify maintenance
• Mobile electronic handwheel for fast setup
• Steady rest for long workpieces included
• Powerful coolant system, dresser, wheel balancer and operating tools included in the standard package

NC control

• NC positioning control allows combining roughing, finishing and spark-out in one operation
• Individual grinding cycles programmable via touchscreen without programming knowledge
• HMI provides intuitive menus for longitudinal and traverse cylindrical grinding
• Detailed graphics assist data entry and show current machining status
