How to maintain and repair CNC EDM box

First check the three-phase power supply is normal, whether the lack of phase, and then check the fuse box device is intact, then check the corresponding printed circuit board fuse is intact.

1. After the CNC EDM electromechanical box is opened, no display is displayed.

Check if the monitor display card inside the computer is loose or replace the display card.

2. The CNC EDM puncher failed to start the computer.

According to the display of the display to determine the corresponding action, generally should be poor contact between the motherboard and the slot or memory board on the motherboard.

3, CNC electric spark piercing machine computer crashes or computer internal alarm.

The CPU fan on the main board is stopped or the air inlet of the computer casing is contaminated. Replace the CPU fan and clean the air inlet grille.

4. When the CNC electric spark piercing machine is processing, the voltmeter has no voltage:

1 Check whether the KM4 is closed 2 Check the power rectifier bridge and related devices 3 Check the power circuit board or replace 5. The CNC electric spark piercing machine does not feed or return.

Check the status of the servo control board or replace it.

6, CNC electric spark piercing machine discharge that produces a strong spark.

The VMOS tube on the power supply PCB is damaged or the control has failed. Replace the power supply PCB.

7, CNC EDM machine without working fluid. Pump motor does not turn:

1Check whether the thermal relay FR has actuated 2 Whether the working fluid pump is blocked or the motor is lack of phase 3 The filter is clogged and the working fluid is not enough

Truck Crane

A mobile crane is a kind of lifting and handling machinery widely used in ports, workshops, electric power, construction sites and other places. The name of the crane is the uniform title for lifting appliances. They are designed to easily transport to a site and use with different types of load and cargo with little or no setup or assembly. There are four principal types of mobile cranes: truck crane, rough-terrain crane, crawler crane, and floating crane.

A truck crane, also called a truck mounted crane has two parts: the carrier, often referred to as the lower, and the lifting component which includes the boom, referred to as the upper. We mainly supply two kinds truck cranes, one is with the crane with self-made chassis, one is the crane with the truck chassis. About the truck crane, we have 3ton, 4ton, 5ton, 6ton, 8ton, 10ton, 12ton, 16ton, 20ton, 25ton for choice, also can be customized as you required.
