The back plate serves as the interface between the lathe spindle and the chuck body, allowing secure attachment and accurate chuck positioning. It is manufactured to fit the D Series spindle nose standard, specifically the D1-4 taper-cam configuration common on mid-size engine lathes and toolroom lathes. Machinists and machine tool technicians install this component during chuck changeovers or when setting up a new chuck on a compatible spindle. Weighing 7.16 pounds, it is a solid, precision-machined part built for repeatable, rigid chuck mounting.\u003c\/p\u003e\n\u003cp\u003eThis back plate is suited for shop environments running lathes with a D1-4 spindle nose where a 6-inch chuck is the specified tooling size. Typical applications include general-purpose turning, facing, and boring operations in job shops, maintenance shops, and production environments. The adapter is sized for a 6.0000-inch chuck diameter and matches the D Series mounting geometry. Installation is performed during scheduled chuck changes or when configuring a lathe for a specific workholding setup.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFits 6-inch nominal chuck size with 6.0000-inch chuck diameter compatibility\u003c\/li\u003e\n  \u003cli\u003eD1-4 camlock mount for secure, repeatable spindle-to-chuck connection\u003c\/li\u003e\n  \u003cli\u003eD Series spindle nose type for broad compatibility with mid-size lathe spindles\u003c\/li\u003e\n  \u003cli\u003eSolid construction at 7.16 pounds for rigid, vibration-resistant chuck support\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 or new-setup adapter back plate for lathes equipped with a D1-4 camlock spindle nose accepting a 6-inch chuck.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation of a chuck adapter back plate is performed by a qualified machinist or machine tool technician. Power down and lock out the lathe before handling any spindle components. Clean the spindle nose taper and camlock pins thoroughly before seating the back plate to ensure accurate registration and prevent fretting. Torque the camlock studs evenly and verify runout with a dial indicator before putting the chuck into 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: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChuck Diameter Compatibility\u003c\/strong\u003e: 6.0000 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: D1-4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 7.16 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: 429-3719\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51691338334514,"sku":"429-3719","price":209.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/426a2204c55a82ad0df059fa913d0ae6.jpg?v=1788283456","url":"https:\/\/voomisupply.com\/products\/value-collection-429-3719-lathe-chuck-adapter-back-plate","provider":"Voomi Supply","version":"1.0","type":"link"}
