The lefthand scrolling photos: The critical control points during manufacture and operating on Oxygen Fuel Flame Cutting Machine
1. Cutting Precision: CNC Flame Cutting Machine has the same cutting precision as other types of CNC Cutting Machine: Plasma cutting and laser cutting. The difference only lies in roughness of cutting kerf;
2. Production Process Technology: CNC Flame Cutting Machine has the same order to deliver value chain with other types of CNC Cutting Machine: Mechanical structure / CNC control system/ Outsourced parts. The difference only lies in specific cutting technology;
3. Cutting Torch Movement in plasma and flame CNC Plate Cutting Machine along X and Y axis are driven with servo motor, and guided with heavy duty precise linear guiderail;
In CNC Oxygen Fuel Flame Cutting Machine, capacitance type height controller is installed onto CNC control cutting torch;
Cutting torches in flame CNC Plate Cutting Machine is equipped with auto ignitor. This helps efficient and automatic ignition of cutting gas, in safe and reliable way.
In practical application, the exact applicating form of CNC Flame Cutting Machine varies, which can be designed and manufactured based on customer condition and requirement:
The above 1st and 2nd Photos:
1) CNC Cutting Torch: 2 sets, being installed at the front side of horizontal gantry beam, for cutting out shape parts in identical or mirror symmetry;
2) Strip Cutting Torch: 9 sets, which are installed at rear side of CNC Cutting Machine mechanical gantry beam, for cutting out strip plates in batch;
3) Advantages: Standard configuration CNC Flame Cutting Machine can meet majority of customer demand. So, it is the basic form of flame CNC Plate Cutting Machine;

The above 4th Photo:
1) Control and Applicating Form: The sole purpose Triple Oxygen Fuel Flame Cutting Machine does not need CNC control; Or, CNC Flame Cutting Machine to be added with 1 or 2 sets of triple cutting torches;
2) Triple Torch Installation Position: Usually triple cutting torches are installed at the both sides position of CNC Cutting Machine mechanical gantry beam: The right most or left most, for the purpose of making edge beveling on edges of steel plate;
3) Integrated Function: With configuration of triple/ strip cutting torches, the CNC Flame Cutting Machine is upgraded into a three in one multi-function CNC Cutting Machine.
Outline: Compared with other types of CNC Cutting Machine, cutting technology in CNC Flame Cutting Machine is relatively simple and quicker to command. On the other hand, there are still some critical points in the cutting technology:
The above 1st and 2nd photos:
1) Arrangement: For all the Oxygen fuel cutting torches of CNC Plate Cutting Machine, be it CNC control/ Strip/ Triple cutting torch, there are always three ways of cutting gas deployment: Blue color preheating Oxygen; Blue color cutting Oxygen; Red color Acetylene or Propane;
a) Preheating Oxygen in the range of 0.5~ 1 MPa;
b) Cutting Oxygen in the range of 1.0~ 1.2 MPa;
c) Acetylene or Propane cutting gas around 0.25 MPa.
3) Preheating for Ignition: To start on flame cutting in CNC Flame Cutting Machine, first turn on preheating oxygen. The duration depends on thickness of steel plate in the CNC Cutting Machine: The thicker the plate, the longer the duration of preheating;
The above 3rd and 4th Photos:
1) Capacitor Type Height Controller: The height controller is installed at top half of cutting torch; Induction ring is assembled at bottom of the cutting torch, surrounding cutting tip;
2) Auto ignitor is installed alongside the induction ring in the cutting torch;
