Shaft machining process:

Material preparation → Turning both ends, drilling center hole →Rough turning each outer circle→ quenching →Repair grinding center hole →Semi-precision turning of the outer circle, slot, chamfering →Thread→ Keying Groove Processing Line →Milling keyway→ Repair grinding center hole→ Grinding→ test.

The process of shaft manufacturing can be Rough turning→ semi-finishing turning→ finishing turning→ grinding based on the high accuracy requirement.

Shaft processing needs to pay attention to the dimensional accuracy, geometric accuracy, surface roughness, mutual position accuracy, etc...

Processing and precautions:

(1) The order of machining should be followed based on the principle arrangements: First base surface, First coarse, then fine grinding.

(2) After machining the center hole for the main shaft part, process the outer circle →the inner hole, and pay attention to the rough and fine processing separately.

(3) The deep hole processing is typically processed after quenching. It is difficult to correct the deep hole after it is bent and deformed, as the deformation of the quenching and tempering treatment is large.

(4) When processing the outer surface of the outer circle, the large diameter outer circle should be processed first, and then the small diameter outer circle should be processed. So as not to reduce the rigidity of the workpiece at the beginning.

(5) The machining of minor surfaces such as splines, keyways, etc. on the main shaft is generally performed after the outer fine wheel or rough grinding and before the rough grinding of the outer circle.

(6) Spindle threading is performed after the partial quenching of the spindle. The concentricity of the threaded surface and the supporting journal shaft is not affected by the deformation after quenching.

If you are looking for a supplier for shaft machining, Bomei provides an in-depth look at the shaft manufacturing process. This process begins with the design of the shaft, and proceeds through the various stages of manufacturing.
