MORI SEIKI SL-35 CNC LATHE

A 10-inch chuck is a medium to large-capacity workholding device designed for lathe and machining center applications. This chuck size accommodates workpieces with diameters up to approximately 10 inches, making it suitable for processing round bars, rings, pipes, and other cylindrical components. The chuck functions as a precision clamping mechanism that securely holds workpieces during cutting, grinding, or milling operations, with typical repeatability tolerances ranging from 0.0005" to 0.001" TIR (total indicated runout). Ten-inch chucks are available in multiple jaw configurations, with 3-jaw and 4-jaw designs being most common. Three-jaw chucks offer versatility for round and hexagonal workpieces, while 4-jaw versions provide independent jaw control for irregular shapes and custom workholding applications. The chuck body is typically constructed from either forged steel or cast iron, with hardened and ground jaws ensuring extended service life and consistent gripping performance. These chucks accommodate various mounting options, including direct-mount configurations for specific spindle types and plain back designs that utilize adapter plates for compatibility across different machines. A 10-inch chuck generates substantial clamping force suitable for high-speed operations and heavy-duty cutting applications, though the specific control mechanism—whether manual, hydraulic, or pneumatic—varies by model. Quick-change jaw systems and machinable jaw inserts are often available as options, enabling rapid setup changes for multi-product production environments.
