The tool movement path of the CNC machine tool is determined by the processing program, so as long as the program can be programmed, no matter how messy the workpiece surface is, it can be processed.
1. High machining accuracy and good standard commonality.
The precision of CNC machine tools is relatively high. Generally, the positioning accuracy of CNC machine tools is 0.02mm. The operator does not participate in the operation during the processing process. Therefore, the machining accuracy of the workpiece is all guaranteed by the machine tool, eliminating the operator's human error. When handling logs and sawn timber, special tools, such as hooks, hook rods, etc., should also be used, and the operator's hands should not directly touch the wood. Therefore, the processed workpieces have high precision, good standard consistency and stable quality.
2. High production efficiency.
The spindle speed, feed speed and rapid positioning speed of CNC machine tools are high. Through reasonable selection of cutting parameters, the cutting function of the tool can be fully exerted and the cutting time can be reduced. Not only can high precision be guaranteed, but also the processing process is stable; Central measurement can end the entire machining process one after another, reducing auxiliary action time and downtime. Therefore, CNC machine tools have the advantages of high production efficiency, simple operation, high precision, and ultra-high cost performance. Compared with traditional carpenter lathes, CNC woodworking lathes have the advantages of simple operation and high precision.
3. It can reduce the labor intensity of workers and complete the operation of one person and multiple machines.
Generally, after a qualified workpiece is processed by a CNC machine tool, the worker only needs to mount the workpiece and start the machine tool, thus reducing the labor intensity of the worker. The current CNC machine tools are reliable and high-quality, with complete maintenance functions, and the CNC system has self-diagnosis and self-stop functions, so when the processing time of a workpiece exceeds the clamping time of the workpiece, it can complete the operation of one person and multiple machines.
4. Although the one-time investment and daily maintenance costs of CNC machine tools are much higher than those of ordinary machine tools, if the superior functions of CNC machine tools can be fully utilized, it will bring high economic benefits. These benefits are not only reflected in high production efficiency, good processing quality, and less waste, but also in the use of CNC machine tools to reduce tooling and cutting tools, shorten production cycles, and shorten the trial production cycle of new products. .
5. It is possible to calculate the cost and organize the production. On the CNC machine tool, the time required for processing can be estimated, and the same workpiece takes the same time, so the working hours and labor costs can be accurately estimated. This is conducive to the preparation of the production development table, and is conducive to balanced production and higher estimated production.
6. CNC machining is the foundation of CAD/CAM technology and advanced manufacturing technology.
