SCHUNK has introduced the ROTA THW3 2+2 power lathe chuck, a versatile clamping solution designed to handle round, cubic, and irregular workpiece geometries with speed and flexibility. Equipped with centrally compensating workpiece clamping, the new chuck enables users to boost productivity while reducing maintenance requirements, offering a single solution for a wide range of machining applications.
For contract manufacturers and machining companies, where short setup times and adaptability are crucial, especially in batch size 1 and high part variability, the ROTA THW3 provides process stability and efficiency. Its design supports modern turn/mill centers that require simultaneous turning and milling, ensuring precise machining even for irregular or geometrically undefined parts during secondary clamping operations.
With this innovative clamping concept, SCHUNK delivers a robust answer to the growing demand for reliable, flexible, and high-performance workholding in advanced manufacturing environments. This 4-jaw lathe chuck features two independent jaw pairs with subsequent centrally compensating workpiece clamping, enabling safe and reliable clamping of freeform parts, castings, or geometrically undefined workpieces. Thanks to the patented sealing, companies can confidently use this 2+2 compensation lathe chuck in harsh environments with dirt and fine chips. In addition, users benefit from consistently high clamping forces and significantly extended maintenance intervals, resulting in increased productivity without compromising quality.
Four jaws for maximum flexibility
Following the manual lathe chucks, SCHUNK now introduces a 2+2 jaw compensation lathe chuck for power lathe chucks, which is particularly indispensable for automated applications. The new power lathe chuck provides centrally compensating workpiece clamping for all workpiece geometries, making it an ideal solution for complex parts on lathes. This flexibility allows parts to be completed on lathes that previously required an additional milling operation. The integrated jaw quick-change system enables users to adapt the chuck quickly and easily to new clamping tasks, resulting in a significant increase in productivity. Thanks to the sealing, the maintenance effort is reduced, lowering lubricant consumption and minimizing used grease – making SCHUNK a key contributor to resource-efficient manufacturing processes. SCHUNK will offer the flexible lathe chuck from mid-2026 in sizes 230, 265, and 315 millimeters indiameter.
