6K - Six Jaw Hydraulic Lathe Chuck

6 Jaw Chuck is a specialized type of lathe chuck designed for precision workholding. Unlike the more common 3-jaw or 4-jaw chucks, the 6-jaw configuration provides improved stability and reduced deformation, making it ideal for handling thin-walled, delicate, or easily deformed workpieces. It is widely used in industries such as aerospace, medical equipment, precision engineering, and automotive manufacturing.
The Six Jaw Lathe Chuck suitable for clamping thin-walled workpieces,minimizing deformation.Multipoint clamping for better stability.

Types of 6 Jaw Chucks

  1. Self-Centering 6 Jaw Chuck:
    • All six jaws move simultaneously.
    • Best suited for high-precision applications where quick, repeatable centering is required.
    • Ideal for thin-walled or delicate components that require uniform clamping pressure.
  2. Independent 6 Jaw Chuck:
    • Each jaw can be adjusted independently.
    • Offers maximum versatility, allowing irregularly shaped parts to be securely clamped.
    • Preferred for complex, non-cylindrical workpieces.
  3. Combination 6 Jaw Chuck:
    • Provides both self-centering and independent jaw movement.
    • Offers flexibility in machining applications, combining the benefits of both configurations.

Applications of 6 Jaw Chucks

  • Precision Machining: Essential in industries requiring tight tolerances, such as aerospace and medical device manufacturing.
  • Delicate Workpieces: Ideal for clamping thin-walled tubing, delicate rings, and soft metals where deformation must be minimized.
  • High-Speed Operations: Enhanced stability allows for higher rotational speeds without compromising safety or accuracy.
