How to select the cams for the sections of a circular knitting machine

One of the essential components of the Circular Knitting machine is the cam, which controls the movement of the needle and sinker as well as its form. It can be classified as a sinker cam, half out of the needle (set circle), flat needle (floating line), or needle (into a circle).

The following factors should be given particular consideration when buying cams since they will have a significant impact on the overall quality of the high and low, circular knitting machines and textiles.

First, select the appropriate cam curve for various textiles and fabric requirements. The cam work surface curve will differ since the fabric designer pursued a different, distinct emphasis.

Individual process points must simultaneously withstand high-frequency impact due to the needle or sinker and cam's long-term indication of high-speed sliding friction. For this reason, the national ticket Cr12MoV cam was chosen because the material's good hardenability, fire deformation, fire hardness, strength, and toughness make it more appropriate for the cam's needs. Typically, cam quenching hardness is HRC63.5±1. An excessively high or low cam hardness will have negative consequences.

The roughness of the cam curve surface is crucial since it truly affects how good and long-lasting the cam is. Surface roughness of cam curves is determined by the tools, processing technology, cutting, and other comprehensive factors of the decision (the price of cams from individual manufacturers is typically extremely low, typically found in this link to do articles). Roughness and cam curve work are often calculated as Ra ≤ 0.8um. Inadequate work surface roughness might result in a corner seat heating, the grinding needle heel, and other issues.

Additionally, pay attention to the keyway, cam hole position, relative position, and curvature; failure to do so could have negative consequences.
