A. Business Background of CNC-CG4000 CNC Flame Cutting Machine:
This set of 4,000mm span CNC-CG4000 CNC Flame Cutting Machine was exported to Central Europe together with H Beam Fabrication Machine by Wuxi JACK in 2019, for performing first operation in customer’s Steel Structure facility.
B. Usage of 4,000mm Span Single Drive CNC Plate Flame Cutting Machine:
1. Strip cutting: As you can find from the first photo, there are workpieces cut off from carbon steel plate, on the cutting platform of this CNC Plate Cutting Machine;
2. Shape cutting: Besides cut into strip and or rectangular contour, the sheet metal plates in this CNC Cutting Machine can also be used for plate shape cutting, with the command of CNC system, as shown in the second photo:
CNC controller in CNC Flame Cutting Machine: (Fig.1)
3. Unique Capability of CNC Flame Cutting Machine for Sheet Metal Cutting:
1) Cutting Media: This CNC Plate Cutting Machine utilizes Oxygen and cutting gas of Acetylene or Propane;
2) Its superiority lies in thermal cutting carbon steel of medium and high thickness, especially for workpiece thicker than 38mm, CNC Flame Cutting Machine has irreplaceable position in the field;
4. Specification of CNC-CG4000: 4,000mm refers to max. valid cutting width of the carbon steel plate in the CNC Flame Cutting Machine. This is the most often seen specification of product family of CNC Plate Gas Cutting Machine;
5. Position of CNC-CG4000: In certain sense, this is the universal standard model for the CNC Plate Cutting Machine. All the other models with either wider span or narrower span CNC Plate Cutting Machine are updated on its basis.
C. Structure and Constitutes of the 4,000mm Span CNC-CG4000 Single Drive CNC Plate Flame Cutting Machine:
1. Main Units of CNC-CG4000 Flame CNC Plate Cutting Machine:
One set of CNC-CG4000 CNC Flame Cutting Machine can be divided into five primary units of:
1) Mechanical machine main frame: Servo motor drive gantry horizontal BOX beam;
2) CNC and strip Cutting torch mechanism: Including its gas feeding tubes and supplying system;
3) CNC controller, and electric control system;
4) Parallel cutting rails, 15m length;
5) Cutting platform of the CNC Plate Cutting Machine for laying workpiece, usually made of customer
2. Mechanical Machine Main Gantry Frame of CNC Cutting Machine:
1. Appearance: The attached third and fourth photos reflect on its installation and assembly on CNC Plate Cutting Machine at Wuxi JACK workshop;
2. Structure and Size: The mechanical gantry main frame of CNC Plate Cutting Machine is a long integral horizontal column of 4m length with two lateral boxes. There are travel wheels at the bottom surface of the two side boxes, so that the main frame can travel along cutting rails of the CNC Plate Cutting Machine during its cutting operation:
Mechanical gantry horizontal beam of CNC Plate Cutting Machine: (Fig.2)
3. Critical Working Motions of CNC Plate Cutting Machine:
1) During work of the CNC Flame Cutting Machine, the mechanical main gantry frame carries the cutting torches into movement for carrying out cutting job on workpiece;
2) X Axis: Cutting torches move along both width direction of steel plates, by means of cutting torches travel along the CNC Plate Cutting Machine main frame under servo motor drive;
3) Y Axis: And along length direction of steel plates, by means of the CNC Plate Cutting Machine main frame travelling along cutting rails;
4. CNC System in CNC Plate Cutting Machine:
1) CNC control system is installed at usually the right side of the CNC Plate Cutting Machine main frame, together with the gas supply and control panel (Please check the second photo);
2) In this way, operator of the CNC Plate Flame Cutting Machine can manage and monitor the working process within arm reach.
D. Working Features of Oxygen Fuel Flame CNC Plate Cutting Machine:
1. Installation Form of CNC Plate Cutting Machine:
1) At customer site, the CNC Plate Cutting Machine is installed in the way of:
2) Both sides of the horizontal gantry beam boxes are engaged into cutting rails of 15m length or longer, as you can observe from the first photo;
3) Precision Management: Parallism and linearity of cutting rails should be adjusted within stipulated precision tolerance;
2. Cutting Torch Mechanism of CNC Cutting Machine:
1) This is execution unit of the CNC Plate Cutting Machine. Its quantity depends on customer designation;
2) In the CNC Flame Cutting Machine of the first photo, there are four sets of single torches and one set of triple torch;
3) In the CNC Flame Cutting Machine of the third photo, there are two sets of single torches;
3. Way of Cutting Torch Work in CNC Plate Cutting Machine:
1) Here we want to stress that, with one set of CNC controller, all the cutting torches in one set of the CNC Plate Cutting Machine work in unison, implementing identical cutting program;
2) So, you can use two sets of cutting torches to cut out two pieces of identical finished parts, or three torches for getting three identical parts, and so on;
3) Of course, due to the width of cutting torch itself to be assembled into gantry beam of the CNC Plate Cutting Machine, it should not say that the more the torch the better;
4) Recommended Qty of Cutting Torch for CNC-CG4000: For CNC Plate Flame Cutting Machine of 4,000mm valid width, which is model CNC-CG4000, the optimum quantity of cutting torch is two sets;
4. Oxygen Fuel Cutting Units in Flame CNC Plate Cutting Machine:
1) Important Function Elements: In CNC Flame Cutting Machine, cutting torch is usually equipped with auto ignitor and height controller, to get the best performance of cutting. For its introduction, please check product section of “Multi Purpose CG4000 Single Drive CNC Plate Gas Cutting Machine”;
2) Thermal Gas Panel: Besides, the cutting torch system should be supplied with three routings of preheating oxygen, cutting oxygen and cutting gas. For its requirement, please check product section of “Combined CG5000 Double Drive CNC Plate Flame Cutting Machine”.
