Application of FGI FD300 Low Voltage Frequency Inverter in sanding machine

1.Overview

The sanding machine is a machine tool that uses the abrasive material (sandpaper or sand belt) to sanding and polish the surface of the parts and components. It is often used in wood polishing, metal deburring and other scenes. In building materials, woodworking furniture processing, metal materials processing and other industries has a widely used. Sandsanding machine can be divided into handheld sanding machine and desktop sanding machine, this mainly introduces desktop sanding machine.

Table sanding machine is mainly divided into roller sanding machine, disk sanding machine, belt sanding machine, brush sanding machine, combined sanding machine, special shape sanding machine. The structure of these sandmachines is mainly composed of base, grinding wheel, motor, dust cover, etc. The main difference is that the installation mode of the abrasive is different to cope with the grinding needs of different parts.

2.Implementation plans

Using FGI FD300 series low voltage frequency inverter, controlling the automatic sanding machine of the rotation speed and feeding speed of the sand belt, can realize stepless variable speed, reduce manpower demand and increase production capacity. The feeding motor is equipped with an encoder for calculating the processing capacity and workpiece position. The number of sand frame and sand head can be increased or decreased according to the actual demand, and the PLC program controls multiple frequency converter to drive the sand belt motor operation. Through the function of infinite speed regulation, the processing requirements of various materials are met. The sanding machine equipment can start the gas valve according to the increase of the processing volume, and make automatic feeding compensation, to ensure that the sand head will not change the sand cutting effect due to the wear of the grinding wheel, and ensure the unified specification of the finished product.

3. Application advantage

FGI FD300 low voltage frequency inverter has high torque stability, strong overload capacity, and can make the equipment grinding process more refined, and greatly improve the working efficiency of the equipment;

The use of FD300 low voltage frequency inverter makes the equipment run fast and stable, effectively reduce mechanical wear and reduce the failure rate;

FD300 series low voltage frequency inverter has perfect protection functions of overcurrent, overvoltage, undervoltage and overload, making the equipment operation safe and reliable.
