CNC Flame Cutting Machine: The Ultimate FAQ Guide

For all those who want to know all the basics of CNC Flame Cutting Machine, this FAQ guide is for you.

It includes all the relevant detail that makes you pick the perfect CNC Flame Cutting Machine for your business.

Let’s start with our guide.

What is CNC Flame Cutting Machine?

The CNC Flame Cutting Machine is a piece of machinery that uses the ignition mechanism to cut a specific part of the metal or metallic sheet.

CNC Flame Cutting Machine supplier

CNC Flame Cutting Machine

This machine uses oxygen as gas for the flame to cut the metallic parts. The procedure, also termed oxy-fuel cut, is utilized to separate and shape metal parts.

It’s done with a torch that passes oxygen as well as a gas mixture (acetylene, propane, or mains gas) through it. The surface of the steel is preheated by an outer part of jets in the torch tip.

From a primary jet, a distinct oxygen channel is targeted onto the region to also be split. The technique can be conventional, with the worker holding and guiding the cutting torch, or mechanized, with the torch installed on a piece of machinery.

Cutting machines can be pre-programmed by utilizing computing technology to reduce the amount of material wasted when cutting a plate. For massive yields, multi-cutting tip machines are available.

These CNC Flame Cutting Machines are easily available and you can have them custom-made according to your measurements and capacity.

What are the Features of CNC Flame Cutting Machine?

The SENLISWELD CNC Flame Cutting Machine features make it distinct and unique from the rest of the competitor’s products.

Here are the features of the CNC Flame Welding Machine:

  • The beam has a minimal structural element with a high degree of stiffness, a low deadweight, as well as low inertia of motion.
  • The gantry design, which includes a double-driven mechanism for the Y-axis and dual-straight rails for the X, Y, and Z axes, allows the machine to move smoothly and precisely.
  • Eliminate the need for manual operations entirely.
  • Increase the effectiveness of flame cutting by any means.
  • Simple linear construct that is easy to install and maintain.
  • In compressor parts, electrical parts, and operational parts, we use superior world-renowned brand equipment.
  • To regulate the entrance and shutting of the die, an elevated dual crank is used.
  • There is no pollution because the system is highly automated and intellectualized.

All these features vary from manufacturer to manufacturer.

What is the Working Mechanism of CNC Flame Cutting Machine?

The working principle of the CNC Flame Cutting Machine is not difficult.

SENLIWELD CNC Flame Cutting Machine uses the oxygen blend and combustion gases to heat up the workpiece and preheat the material to a certain temperature.

Then the oxygen flow has a high speed to make the metal release heat because of getting oxidized. The oxygen flame torch and plasma torch cut the material.

Interestingly, the cutting of the materials is because of the iron burning in the presence of air (oxygen) and not the melting of the material because of flame.

What are the Cutting Materials of CNC Flame Cutting Machines?

It is important to know the cutting materials of the CNC Flame Cutting Machine to check its compatibility with different materials.

The most commonly treated materials from CNC Flame Cutting Machine are as follows:

  • Copper
  • Stainless steel
  • Aluminum
  • Carbon steel
  • Metal alloy
  • White steel
  • Nickle
  • Titanium
  • Galvanized sheet
  • Titanium plate
  • Iron
  • Alloy steel

All these materials are extensively used in the manufacturing of various products, machinery, and parts.

How Many Cutting Torches are Present in CNC Flame Cutting Machine?

There are two torches that are part of the CNC Flame Cutting Machine which are:

  • CNC flame torch

It has a cutting size of 1500mm-3000mm.

With lightweight properties, the CNC flame torches are easily transported from one place to another to assemble in the CNC Flame Cutting Machines.

The flame torch utilizes oxygen as the combustible fuel. It performs its function with precision as it has aluminum molds fixed into them.

Because of the tiny size, the assembly of CNC flame torch is relatively easy. There is no need of getting specialized assembly and installation tools for the placement of the CNC flame torch.

You can efficiently operate the torch and nest the materials. There are two ways to operate these, either manually or automatically for simple and complex graphic programming with the assistance of fastcam software.

They have an in-built mechanism that recognized various shapes. The CNC flame torch also supports the USB for different loading programs.

  • Plasma torch

A plasma torch is an instrument that creates a controlled stream of plasma.

Plasma spraying, plasma cutting, plasma gasification, and plasma arc welding for disposal of waste are all potential uses for the plasma jet.

What is the Function of Flame Cutter in CNC Flame Cutting Machine?

The primary function of the CNC Flame Cutting Machine is to cut the metallic materials through an oxygen flame torch and plasma torch.

This process occurs due to the combustion of the air mixture of the flame and by heating the material surface, the cutting is done.

Which Factors are Responsible for the Accurate Functioning of CNC Flame Cutting Machine?

Various factors determine the accuracy and directly influence the accuracy of the CNC Flame Cutting Machine.

These are the factors that are important to consider:

  • Selection of cutting gas

The choice of cutting fuel for flame cutting machines seems to have a significant impact on cutting performance.

Acetylene, propylene, propane, and MPS are currently accessible gases. Because combustion products have varying combustion properties, the cutting sequences vary.

By selecting the correct gas, you may maximize the benefits of gas cutting and achieve primary and secondary cutting operations.

Acetylene flames have concentrating heat, extreme temperatures, quick heat treatment time, minimal oxygen use, excellent cutting effectiveness, and low cutting distortion. It’s ideal for slicing thin plates as well as adding smaller components.

The heat from a propane blaze is diffused, the warmth is reduced, the heat treatment time is lengthier than acetylene, its cutting tool is smooth and uniform, and the cut-rate is reduced.

As a result, the cutting price is cheaper than acetylene whenever cutting large areas of thick plates. It is suited for cutting heavy sheets and huge items thanks to the massive heat concentration of the propylene torch’s outer flame.

  • The concentration of Oxygen, Height of Cutting Nozzle, and Speed Selection

The cutter oxygen pressure, cutting speed, and cutting nozzle height are all critical aspects that improve the nature of flame cutting and picking the proper gas.

According to research, as the air concentration increases, the cutting time reduces and the demand for oxygen falls under the designated level of oxygen pressure.

It’s also crucial to choose the proper cutting speed. Even though productivity is high, if indeed the rate is too high, this is vulnerable to severe faults and harsh cuts.

The incised surface is irregular, the cutting acceleration is too sluggish, the output is zero, the oxidized slag attaches, and the cutting parameters are too poor.

When cutting a 40mm metal plate with No. 5 jets, the rated maximum speed is 250-380 mm/min, with a median speed of 315 mm/min. There are ten levels in this category. The cutting velocity is somewhere between 336.6 and 358mm/min, with the finest cutting result.

Cutting quality is also influenced by the size of the cut nozzles.

The flames core can skim the surface of the said piece if the cutter nozzle is set too low, leading the cutting seam for collapsing, slag splashed to obstruct the cutting nozzle, or even backfired.

The flame may not properly heat the incisions if the cutting nozzles would be too tall, leading to reduced cutting capability and trouble expelling slag.

In principle, the flame center, as well as the working surface, should be kept at a distance of 35mm.

  • A sequence of cutting and lead application

A good cutting sequence allows for homogeneous burning of the sheet metal, and internal tensions cancel out, resulting in less thermal destruction of said pieces.

As a result, when trimming the contours of the section, you must use the following principles: interior first, exterior second, little first, huge second, the first back, crossed leaping, and complicated rather, simplified second.

When cutting pieces, avoid dislocation, distortion, and size variation. A good lead location and shape allow for a full cut of its part and steady cutting to ensure proper contouring quality.

The entrance placement of the external contour is usually positioned at the lower corner of the contours, and the leading firms of the internal contour are suited for the form of art, as per the real production circumstances.

  • The device is mobile and it is easy to use on the job.
  • Cutting method: In a pretty narrow radius area, you can swiftly alter the cutting orientation.
  • On-the-spot cutting of huge metal sheets by rotating the cutter rather than the metallic block.
  • The procedure can be done manually or mechanically.
  • For manual cutting methods that are hard to fabricate the cut style and thickness, a gaseous cut seems to be a very cost-effective solution.
  • Physical cutting tools have higher equipment expenses.
What are Some of the Drawbacks of Using a CNC Flame Cutting Machine?

Here are some of the CNC Flame Cutting Machine’s disadvantages:

  • The geometric tolerance seems to be much lesser than when using a manual tool to cut;
  • Effective gas stream control and exhaust facilities are required for burning fuel for metallic oxidation.
  • The process of cutting metal, steel, and cast iron must be improved.
  • The cutting process of high hard steel requires preheating prior to the actual cutting process.
  • It is not recommended to gas-cutting on a large scale.
  • Most of the time, the CNC Flame Cutting Machines are only used for cutting steel, aluminum, or cast iron, but they can cut other metals like titanium too in industries.
  • Sometimes, the red-hot flames can become dangerous to the operators that use the CNC Flame Cutting Machine.
  • The burning of fuel in the CNC Flame Cutting Machine is also becoming a pollutant to the environment.

All these disadvantages can be reduced by improving the design and construction of modern-day CNC Flame Cutting Machines.

How to Determine Whether Your CNC Flame Cutting Machine is Suitable for You or Not?

Some factors determine the appropriateness of your CNC Flame Cutting Machine and help you find the best CNC Flame Cutting Machine for you.

These factors are mentioned as under:

  • The manufacturing material must be of fine quality.
  • There should be proper assembly parts of the CNC Flame Cutting Machines.
  • The machine is operated automatically.
  • All the parts and components are rust-free.
Which Factors are Responsible for Adjusting the Flame of CNC Flame Cutting Machine?

The cutting gas will be reduced by rust dust plus organic matrix, and wrong flame calibration will create variations in cutting level and efficiency. The CNC flame cutting machine’s rpm, fuel usage, pressure, as well as other parameters are all averages.

SENLISWELD machine might, though, run at speeds greater or lesser than these averages, and the worker should be able to determine the cutting velocity and strain parameters in real-time on the basis of these features.

The following factors are responsible for the flame adjustment of the CNC Flame Cutting Machine:

  • The setting of Pressure Parameters

On the airflow outlet, pressure regulator knobs for fuel and oxidant gases must be placed. The operating pressure necessary by gaseous oxygen may be effectively handled with these valves.

Setting the pressure value appropriately should be achieved while the torches are being used. Working pressure that is too high will result in factors such as poor cut efficiency and a poor cutting layer.

The cutting oxygen stream produced by the CNC Flame Cutting Machine is the most important aspect in attaining an excellent cut.

If the CNC Flame Cutting Machine’s oxygen flow is directly in the center of the burning flame, so you can look at a cutting tip that is almost fully circular, the cutting jet has been appropriately adjusted.

When the cutting stream scatters like a brush or becomes virtually undetectable after exiting the cutting jet, the cutting faucet is obstructed. It is suggested that you clean the cutting tip with the cutting tip needles supplied by the company.

The cutting tool can be damaged if you use the wrong instruments.

  • Adjustment of Fire Operation

The spray blended gas must be lit once the CNC Flame Cutting Machine unlocks the thermal oxygen valve as well as the gaseous valve.

Set the temperature as needed, and cut thinner steel plates with a mild heating flame while cutting heavy steel plates with a greater heating flame.

The heated temperature becomes too high if somehow the cutting edge begins to dissolve and that excessive moisture drop-like metals are clinging to it, producing a chain of molten balls.

Whereas if the heated burner is just too low while cutting, this will crack, causing damage to a cut and uneven tempering. The cutting flames stream will appear clean and crisp if the warming flame is correctly regulated.

Setting the optimum distance between both the cutting jet and the material is another crucial component in achieving high cutting quality.

The optimal gap in between cutting jets would be when the peak of the main flame (the heart of the flare) is around 1 mm just above the workpiece. The spacing seen between cutting jets is determined by the nozzle’s size.

Can You Get a CNC Flame Cutting Machine with Customized Dimensions?
