How To Protect The Motor Of CNC Sawing Machine

1. In the PLC control system of the CNC sawing machine, the normally open or normally closed action signal is introduced to the signal input terminal of the PLC, and the start and stop of the sawing machine motor are controlled by the program.

2. Using temperature to protect the sawing machine motor, using thermal devices or thermal resistance, the thermoelectric corner measures the temperature of the motor and gives an overheating signal through the temperature controller to protect the motor.

3. Use the thermal relay to measure whether the current exceeds the rated current value of the CNC band saw motor. When the overload is reached, stop the motor and give an alarm signal to protect the band saw motor.

4. According to the size of the motor power of the CNC sawing machine, select the appropriate current transformer, install it in the electric control box, and introduce the action signal into the control loop. When there is three-phase imbalance or large current, the thermal relay will act, and the control loop will cut off the power supply. .

Radiator This material is widely used in various scenarios, so the requirements for aluminum alloy radiator cutting machine is relatively high, first of all, the material section perpendicality, finish, for the surface cutting burr control is better, including the levelness requirements are also relatively high.

Regarding the verticality of the cutting, this point requires that when the equipment is assembled, the sawing stroke and the cutting surface are 90 degrees, that is, the Angle between the saw blade and the material is 90 degrees, and the saw blade cannot be deflected too much when cutting, which requires the spindle accuracy of the equipment to reach 1 wire or less, if it exceeds this range, The material surface cut out by excessive saw blade bias must not meet the cutting requirements.

When it comes to the requirements of the radiator cutting end face, it is necessary to mention the separated aluminum alloy radiator cutting machine, the separated structure is to separate the material after sawing, and the equipment will not cut the surface of the material twice when the knife is back, which not only ensures the finish of the material section, but also ensures the perpendicality of the material section. If the saw cut out the problem, it can be checked from the main shaft of the equipment, sawing stroke, backrest plate, press cylinder, feed screw and other accessories.

The general material cutting problem is basically caused by the abnormality of the above accessories, which may be the tilt of the backrest plate and the serious wear of the spindle so that the accuracy can not meet the requirements
