Engineered for Precision and VersatilityOur 4 Jaw Chuck is meticulously engineered to deliver tight concentricity and robust clamping, thanks to independently adjustable and reversible jaws. It covers a versatile gripping range of 5 mm to 200 mm, easily handling both small and large workpieces for a range of lathe operations across various industries.
Durability and Heavy-Duty PerformanceMade from high-grade alloy steel and hardened to 55-60 HRC, this chuck is built to withstand demanding tasks in heavy engineering environments. The threaded back plate ensures secure mounting, while precision ground surfaces enhance tool longevity and reliable operation.
User-Friendly Features and MaintenanceHand-operated for maximum control, this chuck comes with a convenient chuck key, and grease nipples simplify routine lubrication. Its design ensures easy, independent jaw adjustment for different shapes and sizes of workpieces, making it suitable for both skilled professionals and industrial users.
FAQs of 4 Jaw Chuck:
Q: How does the independent jaw adjustment benefit the user?
A: The independent jaw adjustment allows each of the four jaws to be set separately, accommodating irregularly shaped workpieces and enabling more precise centering during turning operations. This offers greater flexibility compared to self-centering chucks.
Q: What types of lathe machines is this 4 jaw chuck compatible with?
A: This chuck is designed for universal lathe machines equipped with a compatible threaded back plate, making it suitable for a wide range of metalworking environments.
Q: When should I use the reversible jaws feature?
A: Reversible jaws are ideal for gripping both internal and external diameters. Use them in their reversed position when working with larger diameter parts beyond the standard grip range, enhancing the chucks versatility.
Q: Where should the chuck be lubricated, and how often?
A: Lubrication points are provided via grease nipples on the chuck body. Regular lubrication, typically every few operational days or as per usage intensity, will ensure smooth movement and prolong the chucks lifespan.
Q: What is the benefit of the high jaw hardness rating?
A: With a hardness of 55-60 HRC, the jaws resist wear and deformation during heavy clamping, ensuring consistent performance and extended service life under demanding applications.
Q: How do I ensure optimal clamping force during operation?
A: Use the included chuck key to tighten each jaw individually, checking that the workpiece is aligned and secure. Applying consistent force to all jaws ensures optimal grip, safety, and precision during heavy-duty turning.
