Details of the use of electric tapping machine

Share some details about the use of electric tapping machine.

First, use electric tapping machine to aluminum profile products should pay attention to the following two points:

1, avoid aluminum debris winding tap, aluminum material relative density is relatively small, very soft, so its ductility is very good, so special attention should be paid to tapping teeth.

2, aluminum profile is not easy to damage, so when processing aluminum profile tap damage speed will be relatively fast. Sometimes you will find that when the aluminum profile is tapped, it looks like the aluminum profile is very soft, but the tap is not as durable as the iron tapping product, which is a very important factor.

Electric tapping machine is a kind of internal threading tapping machine for various small and large steel parts of coarse teeth, fine teeth, non-standard tooth pitch positive and reverse fastening connection thread, transmission connection thread and pipe thread. This kind of machine tool belongs to the category of flexible tapping, which is characterized by folding arm operation and ADAPTS to the tapping requirements of thread below M42.

Two, with electric tapping machine to iron workpiece processing thread need to pay special attention to the following points:

1. Pay attention to the special tapping of cast iron

2. There is no need to add lubricating liquid or lubricating oil to the tap

3. Find a piece of iron plate with a thickness greater than three or four times the diameter of the hole, drill a hole as big as the diameter of the tap to be tapped, as a guide

The carbon content of industrial cast iron is 2.5%~3.5%. Carbon exists in the form of graphite and sometimes in the form of cementite in cast iron. Cast iron is a general term for an alloy of iron, carbon and silicon.
