3. Mechanical Frame of Sheet Metal CNC Plate Cutting Machine:

1) Shown in below photo, mechanical frame of the machine is a fully welded gantry structure with moving capability;

2) A set of Wuxi JACK CNC-CG4000 model CNC Strip Plate Cutting Machine installed at customer site:(Fig.2)

3) Internal stress of moving gantry is eliminated by effective heat treatment, so that stability of the entire set of the machine is fully guaranteed, eliminating potential risk of vibration;

4. Drive, Guidance and Transmission on Cutting Torches in CNC Strip Plate Cutting Machine:

1) Planar Drive Cutting in CNC Plate Cutting Machine:

a) Cutting torch movement along longitudinal X axis and transverse Y axis are driven with servo motors of different power;

b) Y axis drive is with 2 sets of 750W servo motor, completing double drive in the machine;

c) Y axis drive is with 1 set of 400W servo motor;

2) Guide and Transmission in CNC Plate Cutting Machine:

a) Shown in below photo, X axis movement is guided with high precision linear guide rails, and transmitted with precise rack:

b) Double tiers of high precision horizontal guiderails assembled on moving gantry of Wuxi JACK machine: (Fig.3) 

c) Y axis adopts with heavy duty linear guide rails, so that mechanical frame running is stable and smooth:

5. Precision Management in Wuxi JACK CNC Plate Cutting Machine:

1) Straightness tolerance of X axis is controlled within 0.3mm/1000mm;

2) Positioning accuracy tolerance is ±0.25mm;

3) These helps guarantee on processing stability and quality of the machine.

B. Technical Features of Sheet Metal CNC Flame Cutting Machine:

1. The Irreplaceable Position of CNC Flame Cutting Machine:

1) Nowadays, even with development on cutting technology of plasma cutting and laser cutting, CNC Flame Cutting Machine still has its firm position among 1^st Operation equipment:

2) When cutting sheet metal with thickness above 50mm, which is usually material of carbon steel, the machine is the only choice for customers;

3) A set of Wuxi JACK CNC-CG4000 model CNC Flame Cutting Machine working at customer plant: (Fig.5)

2. Advantages of CNC Flame Cutting Machine:

1) Low cost of both machine purchase and daily operation, compared with CNC Plasma Cutting Machine and laser cutting machine;

2) The only equipment with ability of cutting 50mm plus thickness sheet metal plate;

3. Disadvantages of CNC Flame Cutting Machine:

1) Cutting speed is lower than plasma and laser cutting, usually in the range of 100~ 1000 mm/min.;

2) Cutting kerf is rough, and need to be trimmed sometimes.

C. Technical Features of Sheet Metal CNC Plasma Cutting Machine:

1. Applicable Field of CNC Plasma Cutting Machine:

1) Position: CNC Plasma Cutting Machine can be viewed as intermediate product between CNC Flame Cutting Machine and laser cutting machine, in terms of cutting thickness, kerf roughness, and cost;

2) Applicable Workpieces: This machine is suitable for cutting ferrous and non-ferrous sheet metal, including carbon steel/ stainless steel/ bronze..., in the thickness range from 1mm to 50mm;

2. Cutting Energy Source and Media of CNC Plasma Cutting Machine:

1) Energy Source: This machine is equipped with different power of plasma cutting supply, for different thickness range of sheet metal;

2) Cutting Media: Cutting gas is compressed air;

3) A set of Wuxi JACK CNC-CG4000 model CNC Plasma Cutting Machine installed at Russian customer site: (Fig.6)

3.  Advantages of CNC Plasma Cutting Machine:

1) Plasma Cutting Speed is raised greatly compared with Oxygen fuel flame cutting, usually in the scope of 1000~ 3000mm/min.;

2) Plasma Cutting Kerf of finished workpiece is more smooth, which do not need subsequent trimming;

3) Cutting Gas Routing in CNC Plasma Cutting Machine is much more concise, by using only compressed air, compared with flame cutting machine;

4. Disadvantages of CNC Plasma Cutting Machine:

1) Environment Issue: During working, the machine generates fairly amount of noise and fume, which is harmful on people health. Accordingly, operator should put on proper PPE;

2) “Complicated” Maintenance: Plasma power supply being equipped in the machine has series of consumables: Cutting tip/ Nozzle/ Electrode... Which is relative complicate to use and service. Accordingly, operator of CNC Plasma Cutting Machine should grasp eligible level of skill.

D. How to Select Proper Model and Configuration of Sheet Metal CNC Flame Plasma Cutting Machine:

Summing up, when customers plan to select a set of CNC Strip Plate Cutting Machine, below are factors for consideration:

1. Max. width and length of workpiece: This determines size and model of the machine;

2. Max. thickness of workpiece: This determines on cutting technology applied: Oxygen fuel, or plasma;

3. Need Strip Cutting or not: This determines quantity of cutting torch;

4. Is there any special requirement on the CNC Plate Cutting Machine? Such as nesting program, etc.;

5. In practical application, configuration is often in the form of combined plasma cutting and Oxygen fuel flame cutting in the machine and strip cutting:

6.  A set of Wuxi JACK CNC-CG5000 model flame and plasma CNC Strip Plate Cutting Machine working at customer facility: (Fig.7)

E. Summary on Wuxi JACK Sheet Metal CNC Strip Plate Cutting Machine:
