Product overview
The Servogrind® RSM 600 NC is a precision cylindrical grinding machine engineered for long, heavy workpieces and small-batch production. Servo motor drives on both axes replace conventional hydraulics to improve dynamics, accuracy and efficiency. The machine includes a pivoting internal grinding unit for added flexibility. A rigid machine bed, ground guideways and powerful spindle drives ensure high stiffness and repeatability. The modern NC touchscreen control enables cycle selection without programming skills and simplifies operation.

Highlights

• NC touchscreen control with dedicated grinding cycles
• External and internal cylindrical grinding capability
• Servo-driven axes (no hydraulic unit)
• Swivelling table and swivelling work spindle
• Comprehensive standard accessory package

Machine bed

• Heavy machine bed designed for high-precision machining of large and heavy workpieces
• Swivelling table on precision-ground wide V-block guides for excellent vibration damping
• Design distributes table and workpiece weight to minimize tilting moments and increase rigidity
• Robust tailstock for accurate clamping between centers

Feed

• Servo-conventional feed technology for smooth, vibration-free table advance
• Premium servo drives deliver precision and dynamics comparable to modern CNC machines
• Precise, repeatable feed settings with electronic stops
• Preloaded ball screws on all axes reduce friction and breakaway torque
• Lower heat generation for stable conditions in continuous operation
• Drives, spindles and measuring systems enclosed for low maintenance

Grinding headstock

• Headstock on premium linear guides for maximum positioning accuracy
• Extensively supported grinding spindle for high precision and surface quality in roughing and finishing
• Internal grinding unit pivots into the work area and is driven by a separate motor

Work spindle drive

• Work spindle headstock swivels; spindle speed infinitely variable
• Standard 3-jaw chuck Ø 200 mm with high concentricity included

Equipment & maintenance features

• Fully enclosed work area with large doors for easy access and loading
• Centralized controls and all technical parameters on a touchscreen HMI
• LED lighting for visibility and safety
• Automatic centralized lubrication system
• Mobile electronic handwheel for simplified setup
• Steady rest included; coolant system, dresser, wheel balancer and tooling included in standard package

NC control

• NC positioning control combines roughing, finishing and spark-out in one operation
• Individual grinding cycles programmable via touchscreen without programming knowledge
• User-friendly HMI with menus for longitudinal and traverse cylindrical grinding
• Detailed graphics assist data entry and display machining status
