The back plate serves as the mechanical interface between the lathe spindle and the chuck body, transmitting torque and maintaining concentricity during turning operations. It is compatible with D Series spindle nose configurations and accommodates a chuck diameter of 8 inches. This type of adapter is installed by machinists and tool room technicians in job shop, production, and maintenance turning applications. The part ships as a single unit and is intended as a direct replacement or upgrade component for compatible lathe setups.\u003c\/p\u003e\n\u003cp\u003eThis adapter back plate is suited for use on metal lathes equipped with a D1-5 camlock spindle nose. The D1-5 mount is a standardized taper-and-camlock design commonly found on mid-size engine lathes and toolroom lathes in both manual and CNC configurations. It is appropriate for residential shop, trade school, and light industrial environments where an 8-inch chuck capacity is required. Installation is performed during chuck changeover or when configuring a lathe spindle for a specific chuck body that does not include an integrated back plate.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDesigned for 8-inch nominal chuck diameter\u003c\/li\u003e\n  \u003cli\u003eD1-5 camlock mount for quick and repeatable chuck seating\u003c\/li\u003e\n  \u003cli\u003eD Series spindle nose compatibility for standardized fitment\u003c\/li\u003e\n  \u003cli\u003eSold as a single unit, no minimum multi-unit purchase required\u003c\/li\u003e\n  \u003cli\u003e14-pound construction suited to the load demands of an 8-inch chuck assembly\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 8-inch lathe chucks mounted on D1-5 spindle nose configurations.

Before mounting or removing the back plate, the lathe must be powered down and the spindle brought to a complete stop. D1-5 camlock studs should be inspected for wear before seating the plate, and camlock pins must be engaged per the spindle manufacturer's procedure. Verify chuck runout with a dial indicator after installation before returning the machine to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Chuck Size\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChuck Diameter Compatibility\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpindle Nose Type\u003c\/strong\u003e: D Series\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMount Type\u003c\/strong\u003e: D1-5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 14 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31162907\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 429-3728\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51723277369650,"sku":"429-3728","price":254.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9cfb0ccae8bdfc48055ab231c9d275fa.jpg?v=1788602535","url":"https:\/\/voomisupply.com\/products\/value-collection-429-3728-lathe-chuck-adapter-back-plate","provider":"Voomi Supply","version":"1.0","type":"link"}
