It is a practical choice for multi-face machining, radial holes, bolt circles and repeated angular positioning where manual re-clamping reduces efficiency and consistency.\u003c\/p\u003e\u003cp\u003eFor retrofit projects, the rotary table can be evaluated together with an external axis controller, servo system and CNC communication method. This approach is intended for machines where enabling an OEM fourth axis is not economical or is not available.\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\u003ePneumatic brake\u003c\/td\u003e\n\u003ctd\u003eIncluded\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch3\u003eHow to Select an RTA-170 Retrofit Package\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eConfirm the machine table space, X\/Y\/Z travel and spindle clearance.\u003c\/li\u003e\n\u003cli\u003eProvide the workpiece size, weight, fixture height and required indexing angles.\u003c\/li\u003e\n\u003cli\u003eConfirm the CNC system and available interface, such as RS232 or I\/O triggering.\u003c\/li\u003e\n\u003cli\u003eMatch the rotary table with the appropriate external controller, servo and brake control.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eCan RTA-170 be used on a 3-axis CNC machine?\u003c\/strong\u003e Yes.
