Correct use of woodworking engraving tools

The previous article introduced the woodworking engraving machine in detail, then this article will continue to introduce the correct use of woodworking engraving machine tools to extend the service life of wood engraving machine. Below, the article will discuss the correct use of woodworking engraving machine tools from the aspects of jacket size, tool holder, processing thickness and material.

1. The woodworking engraving machine tool holder has good contact with the jacket; the jacket should be firmly clamped to the holder. If the jacket is used for a long time, the inner hole is deformed, and the jacket must be replaced immediately.
2, select the appropriate woodworking engraving machine tool jacket size; can not choose a cross-section, not round, wear, the inner hole has a tapered tool holder, otherwise it will cause the handle to vibrate, the engraving does not achieve the desired effect.
3. When using the woodworking engraving machine, the thickness of the machining should not exceed the thickness that the cutting edge can cut, otherwise the broken knife will appear.
4. Always check the toughness of the woodworking engraving machine tool; if it is blunt, please replace it immediately to avoid the occurrence of broken knife.
5. For cutting of different materials, the cutting speed should be adjusted reasonably. The recommended speed of cutting should be balanced, and the speed should be kept as consistent as possible to achieve better results. If the cutting is too long, it should not stay, and it should be done in one go.
6, the tool should use a special cleaning agent to remove dirt, butter can prevent the tool from rusting. The tool cannot be polished or changed in shape.
Only by mastering the correct use of woodworking engraving machine tools can the woodworking engraving machine shine more and prolong the life of the woodworking engraving machine tool.

Noise problems and solutions of the woodworking machine during the machining of the spindle

As the core part of the CNC woodworking engraving machine, the spindle is the most used and certainly one of the most prone to problems. Due to the long-term high-frequency operation, and the improper use, the spindle is prone to some noise. Then, in the actual operation, how should we deal with some noise from the main shaft?


First, the sound of leaching


The vibration and collision of the retainer and the rolling element are generated regardless of the type of grease, and it is more likely to occur when the torque, load or radial clearance is large.
Solution: Improve the accuracy of the retainer, select the bearing with small clearance or apply preload to the bearing, reduce the torque load, reduce the installation error, and choose good grease.


Second, the sound of sly


When the motor is running without load, it emits a sound similar to a buzzer, and the motor has an abnormal axial vibration, and there is a click when turning on or off.
Solution: Many motors with poor lubrication and ball bearings in winter and at both ends are mainly unstable vibrations caused by axial vibration when the shaft alignment performance is not good.


Third, the impurity sound


Caused by bearings or high-quality cleanliness, an irregular abnormal sound is emitted, sometimes there is no sound, large and small, and occurs frequently on high-speed motors.
Solution: use good grease, improve the cleanliness before grease injection, strengthen the sealing performance of the bearing, and improve the cleanliness of the installation environment.


Fourth, the sound of sly


The sound frequency varies with the bearing speed, and the surface waviness of the part is the main cause of noise.
Solution: Improve the processing quality of the bearing raceway surface, reduce the waviness amplitude, reduce the bump, correct the clearance preload and fit, check the operation of the free end bearing, and improve the precision installation method of the shaft and the bearing housing.
