Lathe and grinding chucks
 ZS Hi-Tru  - with fine adjustment










APPLICATION
Optimized for machining workpieces which must be produced
with maximum concentricity.
Can be universally used, but is especially advantageous on
turning and grinding machines as well as dividing units.

TYPE
Lathe and grinding chuck in steel design with which the
workpiece can be adjusted very sensitively to the desired
concentricity via 3 tangentially arranged adjusting spindles.

CUSTOMER BENEFITS
• Radial fine adjustment for maximum concentricity
• Repeatability 0.015 mm
• Adjusting accuracy within 0.005 mm
• Precision adjustment without opening the
  mounting screws
• Jaws in chuck ground out for concentricity

TECHNICAL FEATURES
- With one set outside jaws and one set inside jaws
- Hardened adjusting spindles as well as their support surfaces
- Hardened spiral ring
- Steel take-up flange
