Product Usage Instructions

Chuck Handling

• Ensure smooth running and quick clamping without exerting excessive force.
• Adjust clamping jaws over the entire range as needed, they are reversible and exchangeable.
• Regularly lubricate the chuck for optimal performance.

Cast Body vs. Steel Body

• Cast body models ZG3 and ZG4 are slightly cheaper and have speed limits adjusted for cast iron.
• Steel body models ZS3 and ZS4 offer higher load capacity and significantly more speed.

Frequently Asked Questions (FAQ)

• Q: What are the advantages of using a four-jaw lathe chuck?
  A: Four-jaw lathe chucks are ideal for holding square, polygonal, and shaped turning elements that cannot be clamped in three-jaw chucks, providing versatility in machining operations.

• Q: How should I maintain the lathe chuck for longevity?
  A: Regularly lubricate the chuck, inspect and replace clamping jaws if worn, and ensure proper handling to prevent damage.

• Q: What is the significance of the chuck’s clamping force?
  A: The clamping force indicates the maximum force the chuck can exert to securely hold the workpiece in place during machining, ensuring precision and safety.
