Description

Technical Field

[0001] The utility model relates to the technical field of numerical control machine tools, in particular to a disc cutter and a tooling capable of double-sided milling. Background Art

[0002] To obtain parts with standard thickness or strict tolerance requirements for thickness, flatness, and parallelism, the traditional CNC machining process is to mill a flat surface from the front as a reference surface, then turn the part over for secondary clamping to process the reverse surface, or use a grinder to grind, or use multi-axis equipment to process, all of which are single-sided milling. This will make it difficult to control the thickness, parallelism, and flatness of the parts, and will also increase machining costs, unstable quality, and unsatisfactory production efficiency. Based on the above problems, we propose a disc cutter and tooling for simultaneous double-sided milling of surfaces. Utility Model Content

A fixed clamping plate 25 is installed on the top of the inner side of the side panel 22.
