Environment Friendly CGU4000 Underwater CNC Plasma Plate Cutting Machine

The other “Special” product in the group of CNC Strip Plate Cutting machine besides table structure CNC Plasma Cutting Machine is Underwater CNC Plasma Plate Cutting machine.

1. Background of Underwater CNC Plate Plasma Cutting Machine:

1) Why underwater cutting?      In conventional dry type CNC Plasma Cutting Machine, plate plasma cutting process generates fairly large amounts of fume and arc light, which is harmful to people health, especially eyesight and breathing, as well as environment protection;

2) Benefit of underwater cutting:      Underwater CNC Plasma Cutting Machine was developed on this background: The underwater CNC Plasma Plate Cutting Machine has the main task to perform plasma cutting in the water, eliminating pernicious fumes and arc lights, in the way of making it absorbed into water.

2. Structure and Operation of Underwater CNC Plate Plasma Cutting Machine:

1)      The most conspicuous technical specialty with Underwater CNC Plate Plasma Cutting Machine is it has a cutting platform infused with water, with water level changeable;

2) Water Infusion:      At the beginning of Underwater CNC Plasma Plate Cutting Machine working, gasbag is inflated with air because of its intake valve being switched on, making water level rises up quickly;

3) Cutting Operation:      By the time the steel plate is inundated with water, the intake valve is shut off, and water level is kept at this level, during the next step of plate plasma cutting on the underwater CNC Plasma Cutting Machine. All the fumes and arc lights generated from plate plasma cutting will be absorbed into water;

4) Cutting Completion:      By the time underwater CNC Plasma Cutting Machine is finished working, its gasbag discharges air with the switching on of its intake valve, making water level descends rapidly.

3. Impact on Cutting Capacity in Underwater CNC Plasma Plate Cutting Machine:

1) Advantage:      The positive side of Underwater CNC Plasma Cutting Machine is, as mentioned previously, it is user friendly and environment friendly;

2) Constraint:     The negative side of Underwater CNC Plasma Cutting Machine is, due to the effect from water, cutting speed/ cutting thickness/ finished product roughness of this Underwater CNC Plate Plasma Cutting Machine degrades in certain degree (Around 15% less);

3) Higher Electricity Consumption:      Meanwhile, for cutting metal plate of same thickness, underwater CNC Plasma Cutting Machine consumes 15% higher electricity than conventional dry type CNC Plasma Cutting Machine;

4) How to Make Choice?      So, the solitary benefit brought along with underwater CNC Plasma Plate Cutting Machine is its dust elimination and arc light absorption. So, which kind of CNC Plasma Cutting Machine, whether it is conventional dry type or underwater to choose from, is a compromise for customer to make decision.

4. Mechanical Characteristic of Underwater CNC Plate Plasma Cutting Machine:

For Underwater CNC Plate Plasma Cutting Machine,

1) Strong Strength:      The mechanical frame of the CNC Plasma Cutting Machine is enhanced wide box body of lower gravity center, which is stress relived after welded into shape, making strong rigidity and good dynamic equilibrium;

2)  Cutting Rails of gantry moving in this underwater CNC Plate Plasma Cutting Machine are of heavy duty 43kg U71 high strength type, with both its top surface and lateral surface machined with grinding;

3) CNC Cutting Torch Height Regulator:     This type of special CNC Plasma Cutting Machine is equipped with initial positioning unit, arc voltage torch vertical regular (Please check the fourth photo), and 360° anti-collision unit:
