Nowadays, CNC woodworking engraving machine has become a must-selected equipment in the wooden door industry, cabinet industry, furniture industry and other industries due to the advantages of high processing accuracy, high quality, and high efficiency. Among them, the knives of the woodworking engraving machine according to the household registration played an important role. So, in the process of using CNC woodworking engraving machine, how to solve the problem of the tool？ Today Leapion Laser will share with you.
This phenomenon mainly occurs in the materials of processing metals, especially when processing steel materials. The main reason is that the cutting heat is too large and the cutting speed is too low.
Solution: 1. Adjust the spindle speed and increase the spindle speed；
2. Reduce the feed speed；
3. Improve the cooling method, change the position where the coolant is applied, and add it to the position where the tool cuts out, which has a better cooling effect.
This phenomenon generally occurs in the processing of non-metallic materials, and the main reason is that the cutting heat is large, which causes the material to melt.
Solution: 1. Replace sharp tools, sharp tools can reduce cutting heat；
2. Increase the feed speed, the feed speed is increased, and the time that the tool stays at one position is reduced, so that the cutting heat received by the unit volume of the material is reduced, and the melting of the material is avoided；
3. Decrease the spindle speed, and reduce the spindle speed correspondingly to reduce the cutting linear speed, so as to reduce the generation of cutting heat and avoid material melting.
The reasons and corresponding solutions are as follows:
1. The feed rate is too fast and the speed is too slow: At this time, it is necessary to reduce the feed speed or increase the speed；
2. Too much cutting allowance: the cutting allowance should be reduced；
3. The extended part of the tool is too long and the clamping part is too small: At this time, the extended part should be minimized to ensure that the clamping times is more than 4 times the handle；
4. The cutting edge of the tool is severely worn: change the tool and regrind, or reduce the cutting speed；
5. The fixture accuracy is too poor: replace the fixture；
6. Spindle or fixture loose: adjust the spindle or fixture；
7. The processing surface is complicated and the row angle is too much: adjust the cutting parameters to ensure the stability of the workpiece；
8. Poor chip removal and serious chip contamination: reselect the tool and change the cooling method.
The reasons and corresponding solutions are as follows:
1. The tool used does not match the setting of the machine itself and needs to be adjusted.
Adjust the ratio of rotation speed to moving speed, generally around 10:1
2. The processing material is too hard: In this case, it is recommended to use coating or PCD.
The reasons and corresponding solutions are as follows:
1. The feed speed is too fast, the blade is too sharp or the sharp corner is too sharp: At this time, the feed speed should be reduced, and should you chamfer with a diamond file to make the blade dull；
2. The accuracy of the chuck is too poor or the installation is poor: replace the chuck, or clean up the debris of the chuck；
3. The fixture rigidity is too poor and the grasping power is not enough: reduce the cutting parameters；
4. The shape of the workpiece is complicated, and there are too many dead angles: change the parameter and programming mode；
5. Unstable installation of the workpiece: improve the tooling and fixture to ensure that the workpiece is stable；
6. Incorrect cutting direction: generally use down milling to cut；
7. Impurities in the material: pay attention to the material and cutting speed.
The reasons and corresponding solutions are as follows:
1. The feed rate is too fast or the speed is too slow: At this time, it is necessary to reduce the feed speed or increase the speed；
2. Severe tool wear: replace the tool；
3. The accuracy of the tool is not high after grinding: it is recommended to use a new tool for finishing；
4. Too much accumulation of cutting chips: clear the cutting chips and change the cooling method；
5. Incorrect selection of cutting fluid: choose the correct cutting fluid；
6. Large tool vibration: Choose a fixture with high rigidity, high precision, and strong grasping force to minimize the tool extension length.
