Cutting without using a coupling? The EX Series?Sankyo's cam-actuated indexing device?solves this problem. This unit uses a roller gear cam mechanism made from a robust globoidal cam and specially designed rigid cam followers (patented). It is rigid enough to hold steady against heavy cutting action. The EX Series does not require any vertical motion or clamping for a faster process that consumes less energy.
No Hydraulic Unit Required
No clamping device required means there is no need for a hydraulic unit.
Reduces Non-cutting Time
Drastically cuts down on non-cutting time because there is no need for clamping and unclamping.
Stable Positioning Accuracy
Non-backlash mechanism has minimal lost motion, yet maximum high accuracy and stability (repeatibility ±2 sec.)
Impressive Production Volume
Sankyo has built more than 20,000 of these units which are in use on many machine tools.
