It is suitable for operations that require repeatable angular positioning, multi-face work and less manual re-fixturing.\u003c\/p\u003e\u003cp\u003eThe table uses hydraulic clamping. A successful retrofit depends on matching the rotary table with the available machine space, workpiece and fixture size, external controller and CNC communication method.\u003c\/p\u003e\u003ch3\u003eKey Specifications\u003c\/h3\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eParameter\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eWorktable diameter\u003c\/td\u003e\n\u003ctd\u003e255 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCenter height\u003c\/td\u003e\n\u003ctd\u003e190 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCenter bore diameter\u003c\/td\u003e\n\u003ctd\u003e80h7 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eThrough bore hole\u003c\/td\u003e\n\u003ctd\u003e50h7 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eT-slot width\u003c\/td\u003e\n\u003ctd\u003e14h7 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eClamping system\u003c\/td\u003e\n\u003ctd\u003eHydraulic clamp\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch3\u003eSelection Notes\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eCheck machining travel and spindle clearance at every indexing position.\u003c\/li\u003e\n\u003cli\u003eConfirm workpiece weight, fixture dimensions and intended machining operation.\u003c\/li\u003e\n\u003cli\u003eReview the CNC system and cabinet layout before selecting an external controller.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat distinguishes THR-255 from smaller rotary tables?\u003c\/strong\u003e The 255 mm table and 190 mm center height suit larger fixtures and workpieces, subject to the host machine capacity.\u003c\/p\u003e\u003cp\u003eRelated pages: \u003ca href=\"\/collections\/4th-cnc-axis-rotary-table\"\u003e4th axis CNC rotary tables\u003c\/a\u003e and \u003ca href=\"\/pages\/contact\"\u003econtact YidaiCNCParts for a compatibility review\u003c\/a\u003e.\u003c\/p\u003e","brand":"YidaiCNCParts","offers":[{"title":"Default Title","offer_id":53452926746996,"sku":null,"price":0.0,"currency_code":"CNY","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0921\/7320\/5876\/files\/THR255.png?v=1758763659","url":"https:\/\/www.yidaicncparts.com\/products\/thr-255","provider":"YidaiCNCParts","version":"1.0","type":"link"}
