Reversible tapping tool holder

The reversible tapping tool holder is one of the early Italian SCM patented tool holders. From the appearance point of view, the structure is relatively large, because the inside of the tool holder There are three sets of gears, and their structure is very different from that of ordinary tool holders. The interior of the tool holder is mainly engaged by the gears. During normal tapping, the machine tool spindle rotates forward. When tapping to the bottom, the gears inside the tool holder separate from the other set of gears. The gears engage, so that the tap chuck begins to reverse, and the tapping process is completed without the machine tool spindle needing to be reversed.

In order to meet the needs of various users, Italian SCM manufacturers provide two types of reversible tapping tap chucks. Wire tool holder. One is the ER chuck, which is suitable for very rigid machine tools, and the other is a torque chuck, which protects the tap from being damaged due to excessive torque. It is suitable for all types of machine tools, and this tool holder is very suitable Used in engine factories, especially parts with large thread processing volume.

Benefits of using reversible tapping tool holders:

1. The machine tool spindle does not need to be reversed to protect the machine tool motor. Extend the service life

2. Improve the efficiency of the machine tool and save the forward and reverse time of the machine tool

3. Protect the tap from being broken and extend the service life

4. Reduce Waste of raw materials, don’t waste time and workpieces by breaking taps
