Knowledge points related to precision carving machine tools

With the continuous improvement of technology, the CNC mold carving machine industry is also constantly developing. Currently, the processing range of CNC mold carving machines is very wide, and the number of people using them is also increasing. Therefore, before operating the CNC mold carving machine, it is necessary to understand the relevant knowledge of the cutting tools, as the cutting tools determine the processing efficiency. Shenzhen Jingdiao CNC Equipment Co., Ltd. is a CNC machine tool production enterprise that integrates scientific research, comprehensive technical development, strong innovation ability, professional and diversified production, and sales. It has more than ten years of experience in processing and production. We have professional technicians who specialize in designing and producing specialized CNC mold carving machines, including mold specific carving machines, graphite specific carving machines, and ceramic processing specific CNC mold carving machines. With high-quality products, good reputation, exquisite technology, quality assurance, and professional service, we have won the praise, trust, and support of our customers. The technical personnel of Xintenghui CNC have summarized several relevant knowledge about CNC mold precision carving machine tools below< Br/>


The first thing to talk about is how to avoid the severe wear and tear of CNC mold precision carving machine tools. Distinguish severe tool wear: listen to the sound produced by the machining process to see if there is a piercing sound; Listen to the sound emitted by the spindle and check if there is a significant phenomenon of the spindle holding back; Does the sensation increase during processing and does the spindle exhibit significant sensations; Judging from the processing quality, there is a phenomenon of occasional good and bad knife patterns on the processed bottom surface. Can severe tool wear continue machining? After severe tool wear, the cutting force can increase to three times normal. The cutting force has a significant impact on the service life of the spindle electrode, and the lifespan and force of the spindle motor are inversely proportional to the power of three. For example, when the cutting force increases by three times, processing for 10 minutes is equivalent to using the spindle for 10 * 33=270 minutes under normal conditions. Causing damage to the spindle and affecting its lifespan. Under what circumstances should the tool be changed? The tool change should be carried out around 2/3 of the tool life limit. Observing the time of tool wear, if the tool shows severe wear after 90 minutes, the next machining should start changing the tool at 60 minutes and cultivate the habit of changing the tool regularly to avoid affecting the machining quality< Br/>


Secondly, how to determine the length of the tool that extends during rough machining on the CNC mold carving machine? Although the shorter the extension length of the tool, the better, in actual machining, if the extension length of the tool is too short, it is necessary to frequently adjust the length of the tool, which will affect machining efficiency. The principle of how to control the extension length of the tool in actual machining is as follows:; Phi; A tool holder with a diameter of 3 can be processed normally by extending 5mm& Amp; Phi; The 4-diameter tool holder can be processed normally by extending 7mm& Amp; Phi; The 6-diameter tool holder can be processed normally by extending 10mm. Try to maintain below these values when cutting. If the length of the cutting tool needs to be greater than the above value, try to control the depth of machining when the tool wears out. This principle is a bit difficult to grasp and operate, so it should be practiced more in daily life. So how to deal with the sudden occurrence of tool breakage during processing?
