This back plate serves as the mechanical interface between the machine spindle and the chuck body, transmitting torque and providing a flat, precision-machined seating surface. It is installed by machinists and toolroom technicians on engine lathes and CNC turning centers equipped with a D1-11 spindle nose. The part is designed to the standard D Series geometry, ensuring repeatable chuck positioning and secure camlock engagement during turning operations.\u003c\/p\u003e\n\u003cp\u003eThis back plate is suited for use on engine lathes, manual turning centers, and similar machine tool platforms that feature a D1-11 camlock spindle nose. It is sized for 12-inch chuck bodies and is a common replacement or upgrade component in production and job-shop environments where chuck swaps or spindle rebuilds require a new mating plate. Installation is typically performed during scheduled maintenance, chuck changeovers, or spindle reconditioning work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNominal chuck size of 12 inches for use with full-size turning chuck bodies\u003c\/li\u003e\n  \u003cli\u003eD Series spindle nose geometry with D1-11 mount type for camlock engagement\u003c\/li\u003e\n  \u003cli\u003e12.0000 inch chuck diameter compatibility for precise fitment\u003c\/li\u003e\n  \u003cli\u003eUNSPSC Code 31162907 for procurement and catalog classification\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement back plate for lathes equipped with a D1-11 camlock spindle nose and configured for use with 12-inch chuck bodies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or toolroom technician.
