What Is The Function Of CNC Cutting Machine Equipped With Frequency Converter?

The CNC Cutting Machine Equipped has become the darling of the furniture industry, and the CNC cutting machine is composed of dozens of spare parts. Without any spare parts, the machine cannot function properly. Today, let's talk about frequency converters. The frequency converter changes the working power frequency of the motor. A control device for controlling the power of an AC motor.

What is the function of the CNC cutting machine equipped with the frequency converter?

The drive motor of the cutting machine needs to drive the machine to complete heavy loads such as cutting, slotting, punching, etc., and the action power consumption is large. If the motor uses "hard start" to directly work on the load, it will have a serious impact on the power grid, and such a start has high requirements on the power grid capacity of the furniture factory, which is not good for equipment and pipelines. In addition, the current of the motor at startup will be 5-6 times higher than the rated current value, which will not only consume a lot of power, but also affect the service life of the motor. When the inverter starts, the motor can be "soft-started", the starting current starts from "0", and the maximum value does not exceed the rated current. Inverter drives are available for "curve" smooth starts. When the current load side of the inverter is short-circuited or the output current exceeds the normal value, the current can be cut off immediately to prevent the motor from burning.

What should be paid attention to when using and installing the inverter?

1. Considering the cooling effect, the internal structure of the inverter should be installed vertically or vertically as much as possible;

2. Do not install parts that are afraid of heat or easy to heat up on the inverter;

3. Once the fan of the cutting machine fails, check the power failure immediately to prevent the inverter from overheating;

4. Regularly measure the electrostatic capacity according to 85% of the rated value;

5. The working temperature is generally required to be between 0-55 °C, but for safety reasons, it is recommended that the temperature be below 44 °C, so a desiccant or electric heater should be placed in the control cabinet with the inverter;

How to correctly standardize the operation of CNC cutting machine

As the main equipment in the panel furniture industry, Wood CNC cutting machine is deeply loved by customers in the furniture industry. In order to ensure the normal operation of the cnc cutting machine for wood and the quality of the product, a relatively complete set of operating procedures for the CNC cutting machine should be formulated. So what should we do? ?

1. Preparation before work

1. After the machine tool is powered on, check whether the switches, buttons and keys are normal and flexible, and whether the machine tool is abnormal.

2. Check whether the voltage, air pressure and oil pressure are normal. Manually lubricated parts should be manually lubricated first.

3. The tools used should meet the allowable specifications of the machine tool, and the severely damaged tools should be replaced in time.

4. Manually reset each coordinate to zero (machine origin).

2. Matters needing attention in the work process

1. Do not touch the rotating spindle or tool. For example, when measuring workpieces, cleaning machines or equipment, stop the machine first.

2. During the operation of the machine tool, it is not allowed to adjust, measure and change the lubrication method of the workpiece, so as to prevent the hand from touching the tool and bumping the finger, and the operator must not leave the post. If the machine tool is abnormal, it should stop immediately.

3. In case of danger or emergency, press the red "emergency stop" button on the operation panel to stop working.

3. Matters needing attention after the work is completed

1. Clean the chips and wipe the machine tool to keep the machine tool clean in the environment.

2. Adhere to the state of lubricating oil and coolant, and replenish or replace it in time.

3. Turn off the power supply and main power supply on the machine operation panel in turn.
