T/WLJC 14-2018 Specifications for Arc Cam Processing

Scope

Scope: This standard specifies the typical processes for arc-face cam milling, heat treatment, and grinding. This standard applies to arc-face cams used in high-speed, backlash-free drive systems. Main technical content: An arc-face cam mechanism refers to a cam whose base body is an arc-shaped rotating body, with the cam profile made into a convex ridge. Through the change of the helical pitch angle of the working surface, the intermittent movement and positioning of the indexing plate are achieved. The driven disc is equipped with rollers evenly distributed along the circumference of the indexing plate. During the development of this standard, the experience of the national major science and technology project "Disc-type tool magazine with automatic tool-changing device" was summarized, and the process methods for arc-face cam milling, grinding, and heat treatment were mainly solved. The arc-face cams manufactured according to this standard have been used in the products of the national major science and technology project "Disc-type tool magazine with automatic tool-changing device", and it has been verified that they are technically mature.
