What is CNC Flame Cutter？

A cnc flame cutting machine is a cutting machine that uses an arc of fire and oxygen to cut metal plate. It can be either conventional, where a worker holds and guides the torch by hand, or mechanized, where it is installed on a piece of machinery. It can be used for cutting various types of materials, including steel, aluminum, and other non-ferrous materials. It is a great solution for large cuts on metal plates, as it can cut more efficiently and quickly than other cutting methods.

What is CNC flame cutter

The CNC flame cutting machine is an industrial metal cutting equipment that uses a combination of oxygen and fuel gas to cut steel plates into pieces. CNC flame cutting machine control system coordinates the movement of a torch on axis(s), allowing it to precisely follow part geometry to create a precise and repeatable cut. It is an ideal choice for high-precision cutting and machining applications.

The CNC machine is operated by a computer that reads a program describing the part’s contours and when to turn the torch on and off. CNC flame cutting machine program is created by a piece of software called a nesting software, which takes a CAD file and translates its geometry into a set of commands for the CNC to read. The torch follows the contours of the part, cutting through each layer and creating a narrow “kerf”. The kerf is then removed and leave a clean edge on the cut piece.

A common type of fuel for flame cutting is acetylene, propane, or natural gas. It is usually combined with other gases such as synergists to improve the flame temperature and cut quality. Natural gas, liquid petrul gas is the most commonly used fuel gas because it has low equipment costs and is available at many locations. However, it is not as effective for cutting thin metals as fuel gas has significant thermal deformation during the cutting process.

How To Maintain CNC Flame Cutter Machine?

The working site and working environment of the CNC flame cutting machine are relatively harsh, and the metal dust is relatively large. Therefore, it is necessary to carry out a comprehensive cleaning and maintenance of the machine, and a special person should be responsible for the lubrication, repair and maintenance of the equipment!

safe operation

CNC flame cutting machine is a kind of precision equipment, so the operation of the cutting machine must be three (fixed person, fixed machine, fixed post).
The operator must be professionally trained and skilled operation, non-professionals do not move.
Before the operation must confirm that there is no external interference, all normal, the cut plate hanging on the cutting platform, the plate can not exceed the cutting range (note: be careful when lifting).

Daily maintenance and maintenance

Every working day must clean the dirt of the machine tool and guide rail, keep the bed clean, turn off the air source and power when off work, and drain the residual gas in the machine tool pipe belt.
If you leave the machine for a long time, you should turn off the power to prevent non-professional operation.
Pay attention to observe the horizontal, longitudinal guide rail and rack surface of the machine without lubricating oil, so that it maintain good lubrication!

weekly maintenance and maintenance

Every week to carry out a comprehensive cleaning of the machine, horizontal and longitudinal guide rail, transmission rack cleaning, filling lubricating oil.
Check whether the horizontal and longitudinal eraser is working normally, if not, replace it in time.
Check whether all the cutting torches are loose, clean up the garbage in the ignition muzzle, and keep the ignition normal.
If there is an automatic height adjustment device, detect whether sensitive, whether to replace the probe.
Check whether the flame cutting nozzle and electrode are damaged, whether the cutting nozzle and electrode need to be replaced.

Monthly and quarterly maintenance

Check whether there is garbage at the total air intake, and whether each valve and pressure gauge work normally.
Check whether all gas pipe joints are loose and whether all pipe belts are damaged. Tighten or replace if necessary.
Check whether all transmission parts are loose, check the gear and rack meshing, if necessary to adjust.
Loosen the tightening device, check whether the clamping block, steel belt and guide wheel are loose or not, and adjust the tightness of the steel belt if necessary.
Check the strong electric cabinet and operating platform, the fastening screws are loose, clean the dust in the cabinet . Check whether the connector is loose (refer to the electrical manual for details).
Check the performance of all buttons and select switches, damaged replacement, and finally draw a comprehensive detection graph to detect the accuracy of the machine.

Trouble shooting Method of CNC Flame Cutter

Gas path introduction: CNC flame cutting machine is composed of preheated oxygen (slow wind), cutting oxygen (fast wind), gas (acetylene or propane).

Fault phenomena: No ignition, no cutting oxygen, no wind, no extinguishing.

Do not ignite: Most of them are due to the lack of preheated oxygen. Check whether the pressure of the oxygen main valve is too high, whether it is beyond the pressure range of the solenoid valve. Reduce the pressure in the pipeline appropriately.

Non-cutting oxygen (fast wind): It is also caused by excessive pressure in the pipeline. Oxygen meter DC often causes these two problems. Replacing oxygen meter can solve them.

Non-extinguishing: Most of them are due to the aging of gas pipeline, which causes the rubber to fall off and block the position of armature of solenoid valve, resulting in inadequate closure, a small amount of gas flow out, and cleaning up the internal impurities of solenoid valve can be solved.

Compare CNC Flame Cutter with CNC plasma cutter

Flame cutting and plasma cutting exhibit substantial disparities in cutting principles, applications, and pros and cons.

Ⅰ. Cutting principle:
Flame cutting involves utilizing the heat energy of the gas flame to preheat the workpiece to the combustion temperature and then spraying a high-speed cutting oxygen stream, enabling it to combust and release heat for cutting purposes.
Plasma cutting employs gas discharge to form a plasma arc with thermal energy to effect cutting, where the arc melts the material and blows it away, thereby allowing the material to be discharged and form an incision.

Ⅱ. Applications:
The advantage of flame cutting lies in its large cutting thickness and low cost. Particularly when the thickness exceeds 50mm, its efficiency holds distinct advantages and it is typically utilized for cutting low-carbon steel. However, it is incapable of cutting high-carbon steel, stainless steel, cast iron, etc., and the heat-affected zone is extensive, with significant sheet deformation.
Plasma cutting achieves the highest efficiency when the thickness is within 6 - 20mm and can be employed for cutting stainless steel, aluminum, copper, cast iron, carbon steel, and other metal materials. Nevertheless, its incision is mediocre and the smoke pollution is more significant.

Ⅲ. Summary of advantages and disadvantages:
Flame cutting holds advantages in terms of cutting thickness and cost, yet the applicable materials are limited; plasma cutting demonstrates advantages in cutting speed and material adaptability, but the incision width is average.
The selection of the cutting method hinges on the specific cutting requirements and application scenarios. For instance, for low-carbon steel materials with significant thickness and cost sensitivity, flame cutting might be the optimal choice. For materials of average thickness and diverse material categories, plasma cutting could be the preferred option.
