Milling sleeve for long axis keyway

The keyway on the milling shaft is a machining that is often encountered by milling machines. It is easier to mill the keyway on the short shaft, but for some particularly long shafts with two keyways that must be on the same line, and the milling machine stroke is not long enough, it requires secondary clamping. It is more difficult to mill the shaft. To this end, we have designed a long-axis milling keyway positioning sleeve, which is designed
