Electrical Requirements for Sparkler equipment Before using sparkler equipment, please consider the combination of the main engine, CNC power supply equipment and accessories, first calculate the electrical capacity required by the sparkler, and then use the sparkler to prepare. Machine molding machine, spark molding machine should use independent air switch, do not share the air switch with other machine tools. When the electrical capacity of the spark molding machine is less than 11KVA, it should be equipped with 50A air switch, and when 11-22KVA, it should be equipped with 100A air switch off. If the sparkler uses an air switch without leakage maintenance, sometimes the air switch will be disturbed by the mixing of the external wires of the power supply.

If possible, choose an air switching loop with a frequency conversion function 100 to 200ma. In order to prevent electric shock and electromagnetic interference, the sparker must be grounded. A better grounding method is to use a ground resistance of less than 10 ohms. The requirements of the spark machine are connected to 380V voltage, three-phase four-wire or three-phase five-wire voltage.

The 50A molding machine uses 6mm wires to stop the wiring. The power supply circuit in the workshop must be equipped with overcurrent load maintenance equipment. The requested security rules must be followed; The allowable net voltage fluctuation of spark molding machine is ± 10%. If it exceeds this range, communication regulator must be used. CNC punch can be used for threading hole, chemical fiber spinneret, spinneret hole, filter plate and sieve plate group hole, engine blade, cylinder cooling hole, pneumatic valve body oil and gas hole, etc.
