How to choose the spindle for woodworking engraving machine

How to choose the spindle for the woodworking engraving machine, one of the most important components of the engraving machine is the spindle. The advantages and disadvantages of the spindle directly affect the processing speed and accuracy of the engraving machine. How does the wood engraving machine choose the spindle? Let's listen to the suggestions given by the Feida engraving machine.
1. If the processing efficiency of the woodworking engraving machine is pursued, the processing speed should be fast, and the amount of the knife should be large. For example, if the solid wood material is processed, a spindle motor with a power of 3KW or more is required.
2. Whether the spindle motor of woodworking engraving machine adopts high-precision bearing. If high-precision bearing is not used, the performance is that the spindle motor overheats after long-time high-speed rotation, which affects the service life of the spindle motor.
3. Listen to whether the sound of the woodworking engraving machine's main shaft rotates at different speeds, whether it is uniform or no noise, especially whether the sound of high-speed rotation is uniform and harmonious.
4. See if the spindle of the woodworking engraving machine is stressed. Mainly whether it can cut hard material with high speed. Some spindles can only cut hard materials at very low speeds, cutting hard materials at high speeds, and the spindle will be seriously lost.

The relevant parameters of the woodworking engraving machine are set to prolong the life.

The stepper motor parameters in the computer wood engraving machine are related to the speed and precision of the engraving machine. Under normal circumstances, the number of subdivisions of the stepper driver is set. Generally, the higher the subdivision number, the higher the control resolution. However, if the number of subdivisions is too high, it will affect the maximum feed rate. For the mold machine users can consider the pulse equivalent of 0.001mm / P (the maximum feed rate is 9600mm / min at this time) or 0.0005mm / P (the maximum feed rate is 4800mm / min); for the precision requirements of woodworking engraving machine For high users, the pulse equivalent can be set larger, such as 0.002mm/P (maximum feed rate is 19200mm/min) or 0.005mm/P (maximum feed rate is 48000mm/min). For a two-phase stepper motor, the pulse equivalent calculation method is as follows: pulse equivalent = screw pitch ÷ subdivision number ÷ 200.
Setting of take-off speed: This parameter corresponds to the take-off frequency of the stepper motor. The so-called take-off frequency is the highest frequency at which the stepper motor can start work without acceleration. Reasonable selection of this parameter can improve the processing efficiency, and can avoid the low-speed segment where the stepper motor has poor motion characteristics; however, if the parameter is selected to be large, it will cause a boring car, so it is necessary to leave a margin. In the factory parameters of the motor, the take-off frequency parameter is generally included. However, after the wood engraving machine is assembled, the value may change and generally decline, especially when doing load movement. Therefore, the setting parameter is preferably determined after referring to the factory parameters of the motor.
Only by setting the relevant parameters of the woodworking engraving machine, and then according to the operation process, the processing efficiency can be improved, and the service life of the engraving machine can be further improved.
