It helps reduce repeated manual re-clamping for multi-face machining, radial drilling, bolt circles and repeatable angular positioning.\u003c\/p\u003e\u003cp\u003eThe table uses hydraulic clamping. For a retrofit project, select the rotary table together with the fixture, external controller, servo system and CNC communication method after checking the host machine layout.\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\u003e170 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCenter height\u003c\/td\u003e\n\u003ctd\u003e135 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCenter bore diameter\u003c\/td\u003e\n\u003ctd\u003e55h7 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\u003e12h7 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\u003eRetrofit Planning Checklist\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eCheck the available machine-table area, load capacity and X\/Y\/Z travel.\u003c\/li\u003e\n\u003cli\u003eConfirm workpiece dimensions, fixture height and required indexing positions.\u003c\/li\u003e\n\u003cli\u003eProvide the CNC model and cabinet details to evaluate RS232 or I\/O triggering.\u003c\/li\u003e\n\u003cli\u003ePlan the hydraulic, servo and electrical-cabinet arrangement as one package.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eCan THR-170 add a fourth axis to a 3-axis CNC?\u003c\/strong\u003e Yes.
