The selection and use skills of CNC lathe tools are particularly important for flat bed series machine tools. The following is a detailed description:
1. Tool selection
A. Tool type selection: According to the processing needs of the flat bed CNC lathe, select the appropriate tool type, such as external turning tools, inner hole turning tools, cutting tools, thread turning tools, etc.
B. Tool material selection: Select the appropriate tool material according to the hardness, toughness and other characteristics of the processing material. For example, when processing materials with higher hardness, you should choose carbide tools; when processing materials with better toughness, you can choose high-speed steel tools.
C. Tool size selection: Select the appropriate tool size according to the size of the workpiece and processing requirements. Too large or too small tool size may affect machining accuracy and efficiency.
2. Usage skills
A. Tool installation: Ensure that the tool is correctly installed on the tool holder, and the fastening screws must be tightened to avoid loosening or falling off during processing.
B. Cutting parameter setting: According to the tool type, material and processing requirements, parameters such as cutting speed, feed amount and cutting depth should be reasonably set. Cutting parameters that are too high may cause tool wear to be too rapid, while cutting parameters that are too low may affect processing efficiency.
C. Tool cooling and lubrication: During the machining process, ensure that the tool is fully cooled and lubricated to reduce tool wear and heat accumulation. This can be accomplished using cutting fluid or coolant.
D. Tool wear monitoring: Check the wear of tools regularly and replace severely worn tools in a timely manner. At the same time, attention should be paid to observing abnormal conditions during the machining process, such as a sudden increase in cutting force, a decrease in the quality of the machined surface, etc. These may be signals of tool wear or damage.
3. Precautions
A. Avoid using damaged tools: Damaged tools will not only affect the processing quality, but may also cause damage to the machine tool. Therefore, once the tool is found to be damaged, it should be stopped immediately and replaced with a new one.
B. Pay attention to the care and maintenance of the cutting tools: Clean, remove rust and oil the cutting tools regularly to extend the service life of the cutting tools. At the same time, keep the knives properly to avoid damage caused by collisions and falls.
Therefore, the correct selection and use of CNC lathe tools is of great significance to improving processing quality and efficiency. In actual operation, the tool type and parameter settings should be flexibly adjusted according to the specific situation, and attention should be paid to the care and maintenance of the tools.
