Precision punching needle processing and processing workpiece quality has a great relationship, so we must maintain high attention, but also fully understand the process of processing, so, precision punching needle processing what steps?

What are the steps of precision needle processing

Punching needle, also known as punch punch punch, english name is punch-pin, is installed on the stamping die for continuous punching punching operation, so that the processed materials occur separation or plastic deformation, so as to obtain the required finished or semi-finished products.

1. Drawing and cutting

The raw materials after testing qualified, through the drawing machine to make the required diameter size, and then cut into a fixed length rod punching needle embryo.

2. Heat treatment

Before heat treatment, the punching needle embryo is straightened on the straightening platform with a dial meter, and then it is heated in the high-frequency electric furnace or salt bath furnace to 800~1300 degrees celsius, stay for 2~5 minutes, the oil is cold hardened, and the needle tip hardness can reach hv590-800 after fine quenching heat treatment. Then low temperature tempering treatment.

3, grinding processing

The punching needle is clamped on the spring clamping head of the machine tool. According to the angle and dimension requirements of the punching needle, the grinding molding is carried out respectively.

4. Polishing

Polishing is to clean up the oil stains and rust on the surface and clean the surface.

5. Inspection and storage

According to the required index index inspection, qualified can be packed into storage.
