Screw barrel manufacturing process

First of all, we need to know that the manufacturing of screw barrels needs to go through several steps. According to different requirements and specifications, the specific process may be slightly different. But generally speaking, they all include the following steps:

1. tempering correction: this is to ensure that the material and hardness of the screw barrel meet the requirements.

2. Blank Unloading: The required blanks are put into the machine tool ready for machining.

3. Rough Turning: Initial cutting of the blank to approximate the desired shape.

4. Drilling and tapping: Drill and tap holes in the screw barrel for mounting other parts.

5. Rough Turning Taper: Further machining the taper of the screw barrel to make it more accurate.

6. Drawing alloy grooves: drawing alloy grooves on the screw barrel to increase wear resistance.

7. Polishing: Smooth the surface of the screw barrel to improve its aesthetics.

8. Milling the screw: Machining the screw to ensure that its shape and size meet the requirements.

9. spray welding alloy: spray welding alloy on the surface of screw barrel to improve its wear resistance and service life.

10. Rough polishing: initially polish the surface of screw barrel to make it smoother.
