Selection of inverter for woodworking cnc routers Upload to:04-26 2021

With the expansion of the woodworking CNC router market, people have more and more demand for woodworking CNC routers, and the requirements are getting higher and higher.

China woodworking CNC router manufacturers suggest that you should pay attention to the inverter of the CNC router when purchasing an CNC router. So What is inverter of the CNC router? Let us first understand the core components of the woodworking CNC router.

The core components of woodworking CNC router

I  Control System

Generally, the control system used on the cutting machine of the CNC router will have the following types of Baoyuan 2000, Beijing Kane, Shanlong, Xindai, Weihong, Ruizhi Tianhong handles, and the new generation system will have (Taiwan New (Alternative 6MA, 6MB) 6MA is generally suitable for common CNC routers, and 6MB is suitable for tool-changing CNC rotuers.

II  Spindle

The spindle is divided into HQD and Italian HSD, divided into water-cooled and air-cooled, and the power is 2.2KW, 3KW, 4.5KW, 6KW and 9KW, which are suitable for automatic tool-changing CNC routers.

III  Inverter

 The inverter of the CNC router is driven by the spindle motor of the CNC router, and the main requirements are stable operation and smooth speed change. The full-speed fluctuation is small, and the low-speed torque is large, which can ensure low-speed cutting.

IV  driver

  The driving system includes a driver and a driving motor, which provide the driving force of the CNC router motion system, which is an important accessory in the CNC router.

V  Guide rail, rack

The rail brand is generally Taiwan rail.

So inverter is one core component of woodworking CNC router. The following are the precautions for inverter of woodworking CNC router purchase.

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

The load type of the woodworking CNC router inverter; such as vane pump or positive displacement pump, etc., pay special attention to the performance curve of the load, the performance curve determines the method of application.

The problem of matching between inverter and load

I.              Voltage matching; the rated voltage of the inverter of the CNC router is consistent with the rated voltage of the load.

II.             Current matching; the rated current of ordinary centrifugal pumps and woodworking CNC router inverters is consistent with the rated current of the motor. China CNC router manufacturers suggest that for special loads such as deep water pumps, you need to refer to the motor performance parameters to determine the inverter current and overload capacity of the CNC router with a large current.

III           Torque matching; this situation may occur under constant torque load or with a deceleration device

When using the CNC router inverter to drive a high-speed motor, due to the low reactance of the high-speed motor, the increase in high-order harmonics causes the output current to increase. Therefore, the capacity of the CNC router inverter used for high-speed motors is slightly larger than that of ordinary motors.

 

If the inverter of the CNC router needs to run with a long cable, measures should be taken to suppress the influence of the long cable to the ground coupling capacitance to avoid insufficient output of the inverter of the CNC router. Therefore, in this case, the inverter capacity of the CNC router should be enlarged by one level or Install the output reactor at the output end of the CNC router inverter.

 

For some special applications, such as high temperature and high altitude, this will cause the inverter of the woodworking CNC router to degrade, and the inverter capacity of the CNC router should be enlarged by one block.

 

China woodworking CNC router manufacturers introduced the selection of inverter for woodworking CNC router, and I hope it will be helpful to you. For more precautions for the purchase of woodworking CNC router, please consult us, we will be happy to help you.
