It is intended for parts that require multiple faces, bolt circles, radial drilling or repeatable angular positioning without frequent manual re-clamping.\u003c\/p\u003e\u003cp\u003eIts hydraulic clamping arrangement and 210 mm table size make it appropriate for retrofit projects where the machine travel, fixture space, workpiece weight and CNC interface have been checked in advance. An external controller can be selected with the rotary table when an OEM fourth-axis expansion is impractical.\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\u003e210 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCenter height\u003c\/td\u003e\n\u003ctd\u003e160 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 machine-table load, usable table area and spindle clearance.\u003c\/li\u003e\n\u003cli\u003eProvide the workpiece diameter, weight, fixture drawing and required indexing positions.\u003c\/li\u003e\n\u003cli\u003eConfirm the CNC system and available communication method before selecting the controller.\u003c\/li\u003e\n\u003cli\u003ePlan the hydraulic, servo, brake and electrical-cabinet arrangement as one package.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat is the difference between RTA-170 and RTA-210?\u003c\/strong\u003e The RTA-210 provides a larger 210 mm worktable and 160 mm center height.
