Self-centring 3-jaw chuck

CORMAK Uchwyt samocentrujący do rur WP300

The WP300 self-centering three-jaw chuck is a specialist accessory designed for clamping pipes and workpieces with cylindrical or hexagonal cross-sections in welding positioners and welding rotators. Thanks to its precise self-centering clamping mechanism, it ensures secure and accurate positioning of the workpiece during rotation, which results in higher quality and repeatability of the welding process.

Key advantages of the WP300 chuck

Precise self-centering mechanism – enables quick and accurate centering of pipes and workpieces, eliminating the need for manual positioning.

High versatility – compatible with many welding rotators and positioners, including models PS310, PS320, and PS360.

Stable clamping – thanks to three independent jaws, the workpiece remains securely clamped even at high rotational speeds.

Robust construction – made of high-grade materials resistant to vibration, loads, and harsh welding environments.

Optimal working diameter – the ability to clamp pipes up to 270 mm in diameter allows for a wide range of applications.

Design and technology

The WP300 model features a compact and durable steel construction designed for intensive operation. The three-jaw mechanism operates synchronously, automatically positioning the workpiece on the axis of rotation. The large outer diameter (300 mm) and the through bore (100 mm) allow for handling a wide range of workpiece dimensions. The mounting holes are designed to ensure full compatibility with CORMAK welding positioners.

Precision and efficiency

The WP300 chuck provides high clamping repeatability, which translates into precise circumferential welds. It shortens workpiece preparation time and reduces setup errors, increasing production efficiency and improving operator safety. The solid construction ensures stable operation even under dynamic loads.

Applications

The WP300 chuck is intended for use in circumferential welding processes, particularly in manufacturing plants, metalworking workshops, and companies involved in steel structure prefabrication. It is used with welding rotators and welding positioners, enhancing their functionality and versatility.
