Plasma And Flame Strip 4m CNC Plasma Plate Cutting Machine

CNC-CG4000 CNC Plasma Cutting Machine:

1) The attached first photo reflects working moment of this set of Wuxi JACK machine for plate shape and strip cutting, with the Max. 4,000mm cutting width: 

2) You can check its CNC plasma cutting torch was cutting a huge diameter of round shape on steel plate.

1. Configuration and Corresponding Functions of Plasma and Flame Strip 4m CNC Plasma Cutting Machine:

1)   Cutting Torch:   This set of 4,000mm specification CNC Strip Plate Cutting Machine has one set of CNC control single cutting torch carriage, which is available for performing both plasma and flame plate shape cutting;

 2) Equipped Plasma Power Supply: The corresponding plasma cutting power supply is PowerMAX1650: It has working capacity of high quality cutting metal plate up to 22mm thickness for plate shape cutting;

3) Flame Strip Cutting:  Besides, this CNC-CG4000 model machine also has five sets of flame strip cutting torch, for carrying out plate strip cutting;

4) Multiple Functions: So, customer of this CNC-CG4000 model machine can get superior quality high efficient both kinds of finished workpiece (Shape and strip);

5)  Various Sheet Metal Materials:    Besides, CNC Plasma Cutting Machine can deliver very good quality in cutting materials of stainless steel/ Al/ And other non-ferrous metal, as well as low alloy steel. So, customer of this model of machine can process more wider scope of metal plates.

2. The CNC Single Cutting Torch Carriage for Completing both Plasma and Flame Cutting in CNC Plate Cutting Machine and its Operation:

1)  Flame and Plasma Cutting Torch with its Motorized Carriage in CNC Plate Cutting Machine:

a) The second attached photo demonstrates on CNC control cutting torch of the machine in closer distance;

b) You can identify that, there are actually two pieces of cutting torches installed on the motor drive horizontal moving carriage:

i) The left piece of cutting torch is used for fulfilling plasma plate shape cutting, which are equipped from supplier of plasma power supply;

 ii) And the right piece of cutting torch is applied for implementing flame plate shape cutting:

2)  Operation: Switching between Oxy-Fuel and Plasma Cutting in CNC Plate Cutting Machine:

a) During working, the switch between plasma and flame cutting on this motor dirve cutting torch carriage is realized with the selection switch on operating panel of the machine:

b) When the machine cut carbon steels, especially thicker plates, with 30mm and above thickness, operator should select flame cutting mode; 

c) When the CNC Cutting Machine cut non-ferrous material sheet metal plates, especially thinner plates  with 30mm and less thickness, plasma cutting is more applicable cutting mode;

3) Cutting Torch Height Controller of CNC Cutting Machine:

a) We have explored in the product section of “High Quality CG5000 Double Drive Model Machine”, the importance of cutting torch height controller during cutting;

b) Here let us have an understanding on its technical aspect:

a) Capacitance Type Torch Height Controller for Flame Cutting in Flame CNC Plate Cutting Machine:

i.   As indicated in below small photo, this is a piece of metallic induction ring surrounding tip of flame cutting torch, and controlled with a white color controller installed on the top section of cutting carriage;

ii.  Please check the second and third photos; This important control unit realizes automatic torch height control during official operation in the working way of non contact type: 

Capacitance style cutting torch controller of flame CNC Plate Cutting Machine: (Fig.2) 

iii.   Working Theory:  During flame cutting, by detecting the capacitance variation between the metallic ring and metal plate, and further signal detecting/ conversion/ amplification, the controller of the capacitance torch height controller sends commanding signal, which in turn makes lifting motor of cutting torch into elevation, so as to maintain the optimum distance between tip of the flame cutting torch and steel plate all the while;

iv. Control Precision Tolerance: In CNC Strip Plate Cutting Machine, the precision tolerance of such capacitance torch height controller can be maintained within ±1mm;

b) The Arc Voltage Type Torch Height Controller for Plasma Cutting in CNC Plasma Cutting Machine:

i.    Selecting Plasma Cutting:   When the selection switch is turned to “Plasma Cutting”, the arc voltage controller for torch height acts. Its controller is a black color box located right above CNC system of the machine, as shown in the fourth photo and below: 

Arc voltage form cutting torch height controller: (Fig.3)

ii.    Working Theory:  The arc voltage style torch height controller is specifically applied for plasma cutting. Its working principle: It utilizes characteristic of constant current in plasma cutting power supply, during cutting operation, detecting on the arc voltage between cutting electrode and metal plate in real time manner. And by way of driving cutting torch up and down to maintain constant arc voltage, which in turn to ensure constant distance between plasma cutting torch tip and metal plate, in the entire period of the CNC Plasma Cutting Machine operation.
