  • Milling Machine: Workpiece holding for milling
  • Drilling Machine: Precision drilling setups
  • CNC Machine: CNC turning and production work

Compatibility Guide

Ideal for medium-large lathes (10"+ swing).
Sizing Rule: Lathe swing diameter must exceed chuck diameter (160mm). Allow clearance for jaw extension. A swing of ≥200mm is recommended for full capacity usage.

Maintenance

Clean regularly. Apply Molybdenum Disulfide (MoS2) grease to the scroll and bevel gears to ensure smooth operation and extend service life.
