TSUGAMI TMA8J CNC LATHE

Technical Description

This 8-inch CNC-controlled chuck is a high-precision, three-jaw self-centering chuck designed for secure and accurate workpiece holding on CNC milling or lathe machines. Constructed from hardened steel, it features an 8-inch (200 mm) diameter body with a bolt hole circle (BHC) diameter around 7.1 inches (180 mm), ensuring robust mounting compatibility. The jaws move simultaneously through CNC control, driven by a precise pinion and coil mechanism, allowing for full-stroke design and uniform clamping pressure. This ensures a wide range of application adaptability, high repetitive positioning accuracy, and low maintenance costs. The chuck supports high rotational speeds (up to approximately 3100 RPM) and offers excellent total indicated runout (TIR) repeatability, typically within ±0.0004 inches, essential for precise machining operations. Its design also emphasizes long service life with wear-resistant surfaces that are hardened and ground for durability and smooth operation. The CNC control enhances automation and ease of operation, allowing for rapid jaw movement and adjustment with minimal manual intervention. Optional configurations and hollow-through options may be available, facilitating the machining of long or complex workpieces. This chuck is suitable for diverse machining profiles, enabling stable and precise machining across various manufacturing environments, particularly in CNC lathe and milling applications requiring reliable, repeatable clamping of round or irregularly shaped components.
