CNC machine tool is the abbreviation of digital control machine tool, which is an automatic machine tool equipped with a program control system. The control system can logically process the program with control codes or other symbolic instructions, and decode it, so as to make the machine tool move and process the parts.
Compared with ordinary machine tools, CNC machine tools have the following characteristics:
● High processing precision and stable processing quality;
● Multi-coordinate linkage can be carried out, and parts with complex shapes can be processed;
● When machining parts change, generally only need to change the numerical control program, which can save production preparation time;
● The machine tool itself has high precision and high rigidity, can choose a favorable processing amount, and has high productivity (generally 3~5 times of ordinary machine tools);
● The machine tool has a high degree of automation, which can reduce labor intensity;
● Higher requirements for the quality of operators and higher technical requirements for maintenance personnel.
Because CNC lathe processing is a high-precision work, and its processing procedures are concentrated and the number of parts clamping is small, so higher requirements are put forward for the CNC tools used. When choosing the tools for CNC machine tools, you should consider The following issues:
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 there will be no accidental damage and potential defects of the tool in the CNC machining, which will affect the smooth progress of the machining, the tool and the accessories combined with it must have good reliability and strong adaptability. Precision metal processing
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, thereby improving 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.
