When choosing tools for CNC machine tools, the following issues should be considered:

1. The type, specification and accuracy grade of CNC tools should be able to meet the requirements of CNC lathe processing.

2. High precision. In order to meet the high precision and automatic tool change requirements of CNC lathe processing, the tool must have high precision.

3. High reliability. To ensure that no accidental damage and potential defects of the tool will affect the smooth progress of the processing in the CNC machining, the tool and the accessories combined with it must have good reliability and strong adaptability.

4. High durability. The tools processed by CNC lathes, whether in roughing or finishing, should have higher durability than those used in ordinary machine tools, so as to minimize the number of times of changing or grinding tools and tool setting, so as to improve the processing of CNC machine tools. Efficiency and guarantee processing quality.

5. Good chip breaking and chip removal performance. In cnc lathe processing, chip breaking and chip removal are not handled manually like ordinary machine tools. Chips are easy to wrap around the tool and workpiece, which will damage the tool and scratch the machined surface of the workpiece, and even cause injury and equipment accidents. , Which affects the processing quality and the safe operation of the machine tool, so the tool is required to have better chip breaking and chip removal performance.
