DM 315 ROHM Three Jaw Lathe Chuck
TECHNICAL FACTS
- Reliable, high-quality flat spiral chucks for universal use
- Centrally clamping three and four-jaw chucks to DIN 6350 for high clamping forces and loads due to heavy workpieces, high speeds and high cutting performance
- Very robust cast iron (ZG) or steel body (ZS), low profile
- Round and axial runout according to DIN 6386
- Very good repeatable clamping accuracy
- For use on lathes, rotary tables, dividing heads, etc.
- Through hole for bar machining
- One set each of drilling and turning jaws, hardened and ground:
– 3 or 4 pcs. drilling jaws BB stepped outwards
– 3 or 4 pcs. DB turning jaws stepped inwards - With clamping wrench and fastening screws
- With cylindrical centering holder (size B, C)
PRODUCT HIGHLIGHTS
Lathe chuck handling
– Smooth-running, quick clamping without particular force
– Clamping jaws adjustable over the entire clamping range, reversible and exchangeable
– Easy lubrication
Cast body versus steel body
– Cast body models ZG3 and ZG4: slightly cheaper, speed limit adjusted to permissible peripheral speed for cast iron
– Steel body models ZS3 and ZS4: High load capacity, significantly more speed
