ZIERSCH Vertical grinding machines
CONTROL
  • User-friendly Z-Control with high comfort
  • Fully automatic grinding and dressing cycles
  • Grinding cycles: external cylindrical grinding, internal cylindrical grinding and face grinding
  • Grinding modes: roughing, finishing and spark-out
  • Dressing cycles divided into roughing and finishing
  • Automatic cross infeed with compensation of the dressing amount
  • Warm-up and night shutdown programs
OPERATION
  • Easy and intuitive operation through a large, user-friendly touchscreen using self-explanatory pictograms
  • Electronic handwheel, usable in Y- and Z-axis, switchable in two stages to 0.001 and 0.01 mm
CAST IRON/ENCLOSURE
  • Rigid cast iron machine components
  • High machine weight for maximum rigidity
  • Full enclosure of the machine with sliding door and front-end mounted service doors; effective splash protection with excellent accessibility
LINEAR GUIDEWAYS
  • Preloaded precision linear guideways in the Y- and Z-axis (Bosch Rexroth) for highest accuracy
TABLE BEARING
