CNC Woodworking Engraving Machine Manufacturers

The frequency converter is used as the main shaft motor drive of the CNC woodworking engraving machine, and the main requirements are stable operation and stable speed change. Full speed fluctuation is small, low speed torque is large, which can ensure low speed cutting. Therefore, the wood carving router  should pay attention to the following points when selecting the inverter to prevent damage to the 

CNC woodworking engraving machine. Analyzed from the following aspects:

1) The purpose of using frequency conversion; constant voltage control or constant current control, etc.

2) The load type of the frequency converter of wood cnc engraver; such as vane pump or positive displacement pump, etc., special attention should be paid to the performance curve of the load, which determines the application method.

3) The load matching problem between the inverter and the CNC woodworking engraving machine;

1. Voltage matching; the rated voltage of the engraving machine inverter is consistent with the rated voltage of the load.

Second, the current matching; the rated current of the frequency converter of the ordinary centrifugal pump and the engraving machine is consistent with the rated current of the motor. For special loads such as deep-water pumps, it is necessary to refer to the performance parameters of the motor, and even the large current determines the current and overload capacity of the engraving machine inverter.

3. Torque matching; this may occur when there is a constant torque load or a reduction gear.

4) When using the engraving machine inverter to drive the high-speed motor, due to the small reactance of the high-speed motor, the higher harmonics increase, and the output current value increases. Therefore, the selection capacity of the inverter of the engraving machine of the high-speed motor is slightly larger than that of the ordinary motor.

5) If the inverter of the engraving machine needs to run with a long cable, measures should be taken to suppress the influence of the long cable on the coupling capacitance to the ground to avoid insufficient output of the inverter of the engraving machine. Therefore, in this case, the capacity of the engraving machine inverter should be expanded by one gear or an output reactor should be installed at the output end of the engraving machine inverter.

6) For some special applications, such as high temperature and high altitude, the inverter of the engraving machine will be derated, and the capacity of the inverter of the engraving machine should be increased by one gear.

The above is the selection method of CNC woodworking engraving machine inverter. It is worth mentioning that the selected inverter must match the scope of use, so as not to damage the machine and affect the production efficiency.

How to choose CNC woodworking engraving machine

First of all, through telephone consultation, we need to know the specific configuration of each manufacturer's machine and the price of the engraving machine. For example, whether the guide rail is a round rail or a square rail; how much power of the spindle motor; the rotation speed; the structure of the bed; the structure of the gantry; the operation mode of the machine, etc.

Secondly, according to the configuration and price given by the manufacturer, select several companies with reasonable prices and good impression as the object of on-site inspection. The on-site inspection must be carried out on the engraving, and the manufacturer's technicians must make samples according to the content you need to process, and look at the engraving samples and processing time. If the effect is not good, there is no need to proceed to the next step. Even the technicians in the factory can't think of the technology, let alone train you to be a master.

In addition, ask about the after-sales service of the engraving machine, how long the warranty is, and which parts are covered; how to solve the problem of the machine; how long to solve it; in addition to how to charge the machine service after the warranty, the charging standard should be asked clearly.

The price of CNC woodworking engraving machine is finally determined. Every manufacturer is different in size. Of course, the price will vary, and these should be considered comprehensively. While you get what you pay for, we also want to buy value for money.
