The CNC router is suitable for occasions where the processed parts are frequently replaced, that is, it is suitable for the production of single-piece, small-batch products and the development of new products, thereby shortening the production preparation period and saving a lot of process equipment costs.

The machining accuracy of CNC machine tools can generally reach 0. 05-0. 1MM. CNC machine tools are controlled in the form of digital signals. Every time the CNC device outputs a pulse signal, the moving parts of the machine tool move a pulse equivalent, and the machine tool feeds the transmission chain. The average error of the reverse clearance and the screw pitch can be compensated by the numerical control device, so the positioning accuracy of the numerical control slotting machine is relatively high.

The machining quality is stable and reliable. When machining the same batch of parts, in the same machine tool, under the same machining conditions, using the same tool and machining program, the tool travel path is exactly the same, the consistency of the parts is good, and the quality is stable.
