SMW Autoblok says its TX Pull-Down chuck features repeatability of up to 0.0004″ (0.01 mm) and is capable of operating under aggressive cutting conditions. According to the company, the chuck is ideal for secondary machining operations where high levels of accuracy and parallelism are required.
The completely sealed chuck disperses cutting forces over a large area. This is especially important for applications with heavy tool loads such as milling or interrupted turning operations. Also, it allows the chuck to hold its accuracy over an extended period of time. Furthermore, the master jaws are pinned to the chuck body, providing additional rigidity and allowing the chuck to work effectively in milling as well as turning operations.
