Description
technical field [0001] The invention relates to a vacuum clamp, in particular to one. Background technique [0002] High-precision, thin-walled parts are widely used in military industry, electronics and other industries. Because of the thin wall and low rigidity of the workpiece, the main problems to be solved during processing are clamping and positioning, and reducing deformation. A stable processing technology needs to be optimized in many aspects such as workpiece clamping, process arrangement, tool routing, cutting parameters, and tool selection. [0003] At present, in the industry, most fixtures process parts through clamping and clamping. The processing cycle is long, the processing process is unstable, the scrap rate is high, and the economic benefit is low. [0004] Therefore, there are defects in the prior art and need to be improved. Contents of the invention [0005] The technical problem to be solved by the present invention is to provide a vacuum fixture...
