Description

technical field

[0001] The invention relates to the technical field of blade processing, and more specifically relates to a special tooling for precision machining of the coaxiality of slitting disc blades. Background technique

[0002] With the development of society, the machining accuracy of workpieces in the machining industry has also entered the stage of micron-level ultra-precision control. In the metal slitting industry, the slitting disc blades used for slitting metal foils with double zero thickness (such as copper foil, aluminum foil, etc.) require high coaxiality and flatness to control the shearing of products. cut quality. In the domestic finishing industry, the flatness has been able to meet the micron-level requirements of the product through grinding, but the coaxiality of the slitting disc blade has always been a bottleneck for domestic manufacturers.

[0003] At present, domestic manufacturers of slitting disc blades mostly process the disc blades on the...
