ZIERSCH Cylindrical grinding machines
Control
  • User-friendly Z-Control with high comfort
  • Manual grinding function with open door at reduced speeds
  • Fully automatic grinding cycle with dressing cycles
  • Grinding cycles: cylindrical grinding and plunge grinding
  • Grinding modes: roughing, finishing and spark out
  • Dressing cycles divided into roughing and finishing
  • Automatic infeed with compensation of the dressing amount
  • Night shutdown program
Operation
  • Easy and intuitive operation through a large, user-friendly touchscreen
  • Electronic handwheels, usable in the X- and Z-axis, switchable in four stages to 0,0001/0,001/0,01 and 0,1 mm
Cast iron/enclosure
  • Rigid cast iron machine components
  • High machine weight for maximum rigidity
  • Full enclosure of the machine with large service and maintenance doors; effective splash protection with excellent accessibility
Linear guideways
  • Preloaded precision linear guideways in the X-axis (Bosch Rexroth) for highest accuracy
Sliding guideways
  • Excellent damping characteristics and high surface finish quality thanks to ground V-flat sliding guideways in the Z-axis
Lubrication system
  • Automatic central lubrication in the Z-axis (slideway oil) and in the X-axis (grease)
Drives
  • Electromechanical drive of the X- and Z-axis
Measuring system
  • Precise positioning using a direct measuring system on the X-axis (Heidenhain) and a rotary encoder on the Z-axis
Spindle technology
  • Continuously adjustable grinding spindle motor with constant cutting speed up to 35 m/s (optionally up to 50 m/s) over the entire range of use of the grinding wheel for the external cylindrical grinding (vconstant)
  • Long service life due to an external cylindrical grinding spindle supported by 6 rolling bearings, grease-lubricated for life
  • Optional: manually swiveling internal grinding attachment with continuously adjustable internal grinding spindle (ZR 600 & ZR 1000)
  • Automatic switch from external to internal cylindrical grinding via B-axis (ZR 300)
Coolant system
  • Maintenance-free belt filter system with integrated channel flushing incl. cleaning gun with hose and magnetic separator for pre-filtration
