CNC flame cutting machine cutting has the advantages of large thickness carbon steel cutting ability, low cutting cost, etc., the following are the specific advantages:

The application of CNC flame cutting machine is mainly limited to carbon steel and large-thickness plate cutting, and will gradually be replaced by plasma cutting in medium and thin carbon steel plate cutting. The speed of cutting carbon-containing metals is faster than that of blade mobile mechanical cutting process, and it is specialized for thick plate materials. The device is portable and can be used in the field.

During the cutting process, the cutting direction can be quickly changed within a small radius.

Quickly cut large sheets of metal on the spot by moving the torch instead of moving the lump of metal, either manually or automatically. For CNC flame cutting machines, which are good for cutting shapes and the cutting thickness achieved, gas cutting is an economical cutting method. The cost of equipment is lower than that of plasma and laser cutting tools.

Main features of the product:

1. Beam: It adopts square tube butt welding structure, which has the characteristics of good rigidity, high precision, light weight and small inertia. All weldments are treated with vibration aging stress relief, which effectively prevents structural deformation.

2. Longitudinal and transverse drive: both use precision rack and pinion (7-level precision) transmission. The transverse guide rail is made of precision machined steel rail, which ensures the smooth operation of the cutting machine, high precision, durable, clean and beautiful; The planetary gear reducer is used for deceleration, which can perfectly ensure the accuracy of the movement and the balance of the high hall.

3. Longitudinal drive frame (end frame): Both ends are equipped with horizontal guide wheels, which can adjust the compression degree of the eccentric wheel at the bottom of the drive frame to the guide rail, so that the whole machine can maintain a stable guide in motion. It is equipped with a dust collector to scrape the debris accumulated on the surface of the guide rail at any time.

CNC flame cutting machine needs to pay attention to the choice of nozzle, different thickness of materials need to use different types of nozzles, and at the same time standardize the operation in the process of use, which can effectively alleviate the problem of nozzle loss

1. The selection of the appropriate nozzle should be based on the thickness of the workpiece cut by the CNC flame cutting machine. When assembling the nozzle, the inner and outer nozzles must be kept concentric to ensure that the cutting oxygen jet is in the center of the preheating flame, and pay attention to tightening the nozzle nut when installing the nozzle.

2. Check the injection and suction situationThe injection suction torch can be connected only after the injection and suction condition is checked normally, and the acetylene skin tube can be connected, which shall be subject to no air leakage and easy to plug in and unplug. When using an isobaric torch, it should be ensured that the acetylene has a certain working pressure.

3. After the ignition of the flame extinguishing treatment, when the preheating oxygen regulating valve is screwed to adjust the flame, if the flame is extinguished immediately, the reason is that there are dirt in each gas channel or the contact between the bell mouth of the injection straw is not tight, and the outer coat of the cutting mouth is not properly matched with the inner mouth. At this time, the injection straw nut should be tightened; When it fails, the pipette should be removed, the dirt in each gas channel should be removed, and the gap between the outer jacket and the inner sleeve of the cutting nozzle should be adjusted, and tightened.

4. After the preheating flame is adjusted normally, the head of the cutting nozzle emits a rhythmic "horn, horn" sound, but the flame is not extinguished. At this time, the cutting nozzle jacket should be removed, the mouth core should be gently tightened, and if it still does not work, the coat can be removed again and padded with asbestos rope.

5. Although the flame is normal after ignition, the flame is extinguished immediately when the cutting oxygen regulating valve is opened. The reason is that the cutting nozzle and the cutting torch are matched, and the fitting surface is not strict. At this time, the cutting nozzle should be tightened, and when it is ineffective, the cutting nozzle should be removed and gently used with fine sandpaper.

Grind the mating surface of the nozzle until it fits tightly.

6. When tempering occurs, the cutting oxygen regulating valve should be closed immediately, and then the acetylene regulating valve and the preheating oxygen regulating valve should be closed. When the normal operation stops, the cutting oxygen regulating valve should be closed first, and then the acetylene and preheated oxygen regulating valve should be closed.

7. Keep the nozzle channel clean, the nozzle channel should always be kept clean and smooth, and the dirt in the hole should be cleaned with a needle at any time.

8. Clean the surface of the workpiece, and the thick rust, oil and water dirt on the surface of the workpiece should be cleaned up. When cutting on the cement floor, the workpiece should be raised to prevent rust scale and slag from splashing and injuring people on the cement floor.

Set the appropriate spacing between the cutting nozzle and the workpiece of the CNC flame cutting machine. If the CNC flame cutting machine is not automatically adjusted, the operator should always pay attention to the appropriate distance between the cutting nozzle and the machined parts. When the tip of the primary flame (the core of the flame) is about 1 mm on the workpiece, it is the ideal spacing of the nozzles.

In addition, it is also necessary to adjust the height of the cutting nozzle appropriately according to the use of cutting gas, such as from 3-10mm when using acetylene, and from 6-12mm when using other gas. On the other hand, if the steel plate is deformed or uneven, it should also be adjusted. When using propane or natural gas as gas, the cutting thickness should be doubled when cutting thickness to 50mm.

The cutting seam of this general flame nationwide is less than 5mm.

1. The general process of manual programming is: analysis of parts pattern - CNC process processing - mathematical processing - writing NC** - calibration and debugging NC program - first piece trial cutting - error analysis, boring, cumbersome, error-prone, and difficult to memorize the instruction syntax.

2. When automatic programming, AutoCAD2000 can directly generate CNC machining from the graphic entity that describes the outline of the part from the two-dimensional graphics, so as to avoid the complex memory of manual programming. Significantly improve the efficiency and quality of programming.

CNC flame cutting machine, cutting has a large thickness of carbon steel cutting ability, cutting cost is low, but there is a large cutting deformation, cutting accuracy is not high, and the cutting speed is low, cutting preheating time, piercing time is long, it is difficult to adapt to the needs of fully automatic operation. Its application is mainly limited to carbon steel and large-thickness plate cutting, and will gradually be replaced by plasma cutting in medium and thin carbon steel plate cutting.

I haven't used it for a long time, and I can't remember some ** clearly, read the manual. The programming is basically the same as CNC machining, G90 X0 Y0 locates the current position as the coordinate origin, M07 or M08 to control the flame on.

Here it is also necessary to pause to preheat the steel plate and then perforate it. See the instruction manual for specific orders.

g01 x200

y100x0y0

M08 Turn off the flame ......

I really can't remember ......

Go to the graphics management to find the graphics and directly enter the size on the line, such as making some special-shaped parts is recommended to use software, and you can also make it yourself, but it is too troublesome.
