Description

technical field [0001] The invention relates to the field of testing a linear motor feed mechanism for a numerically controlled machine tool, specifically a performance test device for a linear motor feed mechanism. Background technique [0002] High-speed / compound CNC machine tools require the feed system to have high feed speed and high acceleration. The linear motor is used to directly drive the worktable for linear feed motion, which realizes the "zero transmission" of the feed system, which is ideal for high-speed / compound CNC machine tools. choose. The way of direct drive of linear motor is a new transmission mode, and the performance of linear motor feed mechanism directly affects the overall performance of the machine tool. Therefore, it is very important to understand the factors that affect the performance of the linear motor feed mechanism for the design, analysis and application of the linear motor feed mechanism. [0003] Due to the structural factors of the l...
