How to do the processing of sticking knife in the process of CNC engraving machine

Those who have used CNC engraving machines know that they often appear stuck in the processing process, so they are completely puzzled. Today, Engraving will help you analyze the specific reasons.

The phenomenon of sticking knife is also the material of sub-machined parts. As the name suggests, wood is definitely not sticking knife. Sticking knife can be divided into two cases: The first case is that the material is melted on the tool. This phenomenon is generally found in non-metallic materials. The main reason is that the material is melted due to the high cutting heat. The solution is 1 to replace the sharp tool, sharp cutting tool can reduce the heat of cutting; 2 to increase the feed speed, the feed speed is increased, the time for the tool to stay in one position is reduced, so that the heat of cutting received by the unit volume of material is Reduced, to avoid the melting of the material; 3 reduce the spindle speed, reduce the spindle speed correspondingly reduces the cutting speed, which reduces the generation of cutting heat. Material melting can be avoided.

The second situation is that the material part melts and sticks to the tool. This phenomenon is mainly found in metal-processed materials, and is particularly likely to occur when the steel is processed. The main reason is that the cutting heat is too high and the cutting speed is too low. The solution is to adjust the spindle speed and increase the spindle speed; 2 to reduce the feed rate; 3 to improve the cooling method, change the position of the coolant applied to the cutting position of the cutter, there is a better cooling effect.
