Multi Structured High Precision CNC Plasma Plate Cutting Machine

Summary on CNC Plasma Plate Cutting Machine:

1) CNC Plasma Plate Cutting Machine accounts for the second biggest volume share in the product family of CNC Strip Plate Cutting Machine;

2) This product section will have a general introduction on this branch of CNC Cutting Machine as an integral group.

1. Application of CNC Plasma Cutting Machine:

1) Origin:

a) CNC Flame Plasma Cutting Machine was developed on the basis of Oxygen fuel fame cutting;

b) In other words, for introduction on the CNC Cutting Machine into use, first came CNC Flame Cutting Machine; On that basis, to meet more demand from customer, so was came CNC Plasma Cutting Machine;

c) Because of this background history, in practical application, over half of the plasma cutting worked in the form of CNC Flame Plasma Cutting Machine;

2) Technical Summary on CNC Plasma Cutting Machine: 

a) The mechanical main structure (Gantry moving);

b) Purpose and application (Carbon steel plate Shape Cutting);

c) Working principle (Cutting torch moves on the metal plate) 

Are all the same or similar to that of the Oxygen fuel flame cutting models.

3) Differences between CNC Plasma Cutting Machine and CNC Flame Cutting Machine:

Mainly lie in below three aspects:

a) The concrete cutting way and media: Plasma cutting utilizes compressed air and Nitrogen as its cutting gas; While flame cutting adopts with oxygen and acetylene/ propane as its cutting gas;

b) Process parameters: The second difference is, CNC Plasma Cutting Machine delivers finer cutting kerf and higher cutting speed than flame cutting. Of which, one kind of plasma cutting --- Fine plasma plate cutting has cutting fineness close to laser cutting;

c) Applicable workpiece materials: The third difference is, CNC Plasma Cutting Machine can work on both ferrous metal of carbon steel, and non ferrous metal of stainless steel and Al;

In summary and in certain respect, plasma cutting can be viewed as the “higher end” product in CNC Strip Plate Cutting Machine family.

2. Structure and Classification on CNC Plasma Plate Cutting Machine:

1) Moving gantry frame: Most majority of the plasma cutting also has the structure of gantry moving. For reference, please check the product section of “Multi Size Gantry Moving Flame models machine”: 

Mechanical main frame of motorized gantry moving Wuxi JACK CNC machine for plasma cutting: (Fig.1) 

2) Table mechanical body: Besides, the CNC Plasma Cutting Machine also has stationary table type structure--- For cutting small size in precise manner (Metal plate length shorter than 3,000 mm or 5,000 mm) and underwater cutting platform --- For cutting metal plate inside a water pool (This is for the purpose of less fume generated during plasma cutting:

Wuxi JACK underwater machine for plasma cutting: (Fig.3 ) 

3)  Further Classification on CNC Plasma Plate Cutting Machine:

So, from the view point of main frame structure,

a) Motor drive moving gantry beam structure, (The largest group in terms of using volume);

b) Fixed table type structure type,  (Ranking the second), usually applied in small size non-ferrous metal high precision cutting;

c) Underwater type, special made.

3. Configuration/ Technical Brief and Cutting Capacity of CNC Plasma Cutting Machine:

1) Working style: Similar to SAW welding Machine and H Beam Fabrication Machine, the plasma plate cutting process in the machine is made with outsourced plasma power supply, in the form of one cutting torch controlled with one set of plasma cutting power supply;

2) Working specifications: In CNC Plasma Cutting Machine, model of its equipped plasma power supply varies in terms of customer demand cutting capacity (Thickness, including good quality cutting and cutting off only) and denoted in the form of output current;

3) Cutting capacity: Currently, the most frequent plasma power supplies to be used in plasma cutting have its cutting capacity falling into the range of: Good quality plasma plate cutting from min. 0.3mm to max. 22mm/ 25mm/ 33mm/ 45mm, with Output Current 30A~ 100A /120A, 40A ~ 160A / 200A / 400A;

4) Performance index: Another important index for CNC Plasma Plate Cutting Machine is duty cycle of plasma plate cutting (Optimum is 100%);

5) Quantity of plasma cutting torch and plasma cutting power supply:  For gantry moving type and Underwater type machine, the most often configuration is one to two sets of cutting torch, or in other words, one to two sets of plasma power supply;

6) For stationary working Table frame type Machine, confined to its machine size, usually the machine has one set of cutting torch;

7) Application Forms of CNC Plasma Plate Cutting Machine:

a) In practical application, majority of plasma cutting have its plasma cutting torch shares with flame cutting torch, installed into the same moving carriage; 

b) Or still further, this CNC Cutting Machine is equipped with strip cutting torches and or triple cutting torches, making the original single function machine into a general purpose multi function CNC Strip Plate Cutting Machine;

8) Detailed technical parameters we will have a list in the later corresponding specified model of each model of the machine.
