2 cutting types by waterjet

Generally, there are two water cutting process, namely the pure water cutting technique and abrasive waterjet cutting process.

Pure water cutting

The pure water cutting technology is meant for soft materials such as food, rubber, textiles and leather. During this technique, water is pressurized into high levels then forced out through a small sapphire or ruby, releasing an intense cutting steam. The steam jet is believed to move 2.5 times the speed of the sound. This is the reason the pure water cutting technology cuts at a high rate, giving out powerful and precise cuttings.

Abrasive waterjet

On the other hand, the abrasive waterjet cutting technology is meant for hard materials that the pure water technology cannot cut through. As the name suggests, the water nozzle is replaced with an abrasive cutting head. The water steam creates a vacuum thus drawing the abrasive into a chamber facilitating the production of powerful abrasive jet steam.

This is the commonly known waterjet cutting steel process. The abrasive process cuts through nay material such as slab, glass, sheetmetal and aluminum, among others.

How does the waterjet cut intensifier pump works?

As we all know, the waterjet process operates on ultra high pressure to cut through materials. This process starts off with an intensifier pump. This pump creates the ultra high pressure needed to perform various tasks. The intensifier pump is fitted with a large horsepower motor.

Additionally, it uses a hydraulic pressure. This is how the hydraulic pressure is created and powers piston in a cylinder. Here is a list of other requirements used in this process:
A low pressure water inlet
Water off valve
Boost pump
Accumulator
Inlet check valves
Water filler
An intensified piston
Abrasive metering system and a cutting head.

Key point in waterjet cutting systems

The key point to make waterjet cutting is the clean water system is connected to the low pressure inlet. The water is then forced into the inlet filter through the inlet check valves until it reaches the hydraulic pump. This is the stage where water is pressurized. During this stage, the water pressurizes the hydraulic fluid in the hydraulic pump. The pressure then forces water out of the intensifier and finally into the accumulator. The water then flows into the high pressure tubing into the cutting head. The water flow is controlled by the off valve. This valve allows people to achieve their desired cuttings while using the waterjet cutting process. The abrasive is mixed with high water pressure in the mixing chamber.

How does the intensifier work in waterjet cutting services?

People are always asking how the intensifier is able to create the ultra high water pressure. The larger hydraulic cylinder pushes the small piston in a cylinder full of water. This is how the ultra high water pressure is created. High water pressure enhances the cutting process.

How is waterjet cutting head working

Let us shift our gears and look at how the waterjet cutting head works. The high pressure water can be delivered into the cutting head in two ways. It can be through the hose or the high pressure tubing. The water is then applied to an orifice to help resist abrasion of high pressure water. It is mostly made of sapphire and diamond. The orifice is entitled the task of creating the water stream. Not all materials can be cut by the water stream. There are cases where a person will be required to add an abrasive to the water stream to cut through hard materials such as stone, plastic, aluminum and steel, among others.

The abrasive is the one that does the actual cutting. It is made up of crushed garnet. Consequently, there are other materials a person can use for special applications. Lastly, machines can be cut to meet a person’s exact needs.

On the other hand, as oxy fuel cutting technology is developed nowadays, with a proper oxy fuel gas mixture and good temperature control, also we could get a high precision flame cutting (a quality flame cutting). Especially with CNC flame cutting technology integrated in, it has been widely used in steel parts manufacturing processes.

What is Flame Cutting or Oxy Fuel cutting

Flame cutting (oxy fuel cutting or oxy acetylene cutting), as it’s name, with oxy fuel gas burning through a cutting torch, makes a flame and with the flame heat to cut steels. It is an oldest way in hot steel cutting activities. The cutting torch is designed to provide Oxygen fuel gas for to burn the iron oxide, in this way to guarantee the stable of the temperature and get better cutting performances.

Why flame cut steel used much in cutting steels

Flame cut steel is an old and very common cutting steel technology for cutting steels. As we know, metal fabrication entails cutting, heating and welding steel. There are numerous techniques used to shape steel, flame cut steel is one of these techniques and with hardware development now you are able to get a quality flame cutting steel parts. It entails the use of fuel gas and oxygen to cut shapes from the steel plate. This technique is gaining widespread popularity for various reasons.

Here are some of the reasons and advantages:

• Lower cost and lower investment (Flame cutting machine is cheaper than Laser cut or waterjet machine. Even with a oxy fuel cutting revolver you can do the cuts.)
• The only way to cut steel with big thickness (to cut thick steel).
• It is relatively affordable when compared to other techniques.
• It can cut through a large metal surface area. This thickness ranges from 1 millimeter to 1000 millimeters.
• This process is portable. It can be used in different locations, apart from a physical workshop.
• CNC flame cutting technology integrated

Disadvantages

• Cutting parts in bigger transformations (Because of the heat melting will makes larger cutting material)
• Operators should have highly skills and much experiences (To get a better precision size and avoid more hot transformation)

How does flame cut steel plate (oxy fuel cut) process work?

Ever asked yourself the above question? If yes, you are at the right place. The flame cutting steel plate process is thermo-chemical. This process requires intense heat commonly referred to pure oxygen. This oxygen fuel can be found in bulk systems and cylinders. Non pure oxygen reduces the cutting speed of steel. Consequently, pure oxygen fuel can mix with impurities through leaks, bad hoses and improper connections. Pure oxygen fuel should be carefully used or it risks serious injuries.

Cutting materials types

The flame cutting steel process can be use for numerous purposes, provided the oxide formed has a low melting point when compared to the material being cut. This is the reason the oxy fuel cutting process cannot be used with other materials. A perfect example is aluminum.

Flame Cutting (oxy fuel cutting) Types

Flame cutting types mainly divided in torch cutting and CNC flame cutting (machine flame cutting table).

Flame torch cutting

Flame torch also called fire gun. With different gas, the torch has different structural. Most used is Oxygen-Acetylene gas torch, acetylene pressure at 0.01 to 0.12 Mpa, Oxygen pressure 0.50 to 1.0 Mpa. Two different gas burned in it’s own channel and mixed together in oxy fuel cutting torch, the flame could be adjusted manually. This type of oxygen cutting mainly used to re-cutting to remove the defects from the steel billet cutting or steel straightening.

CNC flame cutting for steels

CNC flame cutting is processed by CNC cutting machine, that is to use CNC technology to drive the flame cutting table and cutting torch, to cut steel plate, steel sheet and other metal materials. CNC flame cutting equipment integrated the machine, table, electricity, and flame torch. So it includes three big part: CNC control systems, flame cutting systems, and drive systems.

CNC flame cut steel advantages is it can cut big thick steel plate, lower cost, but disadvantages also the same with common flame cut. Which is big transformation, lower precision, slow cutting speed takes long time for preheating, perforation slow, and is hard for all the auto operations. So it’s application limited to carbon steel, and thick steel plate cutting. For the thin steel plate cutting under 20 mm, it is almost substitute by laser cut, or plasma cutting technical.

How can the flame cutting performances could be enhanced?

There are two factors which influence the performance of the flame cutting process, namely the nozzle selection and the fuel type. These two factors can increase or reduce both the labor cost and the cutting speed. In addition to this, the oxy fuel jet and the gas used influence the cutting period used to cut through a material. In most cases, oxygen fuel is mixed with other fuel gas such as propane, methane; acetylene, propylene and MAPP to reach achieve the ignition temperature. The flame cutting steel temperature must below the material’s melting point. Afterwards, pure oxy fuel is passed through the preheated area to kick off the flame cutting process.

The chosen ignition gas depends on whether the process is mechanized or manually handled, the material type and the work being handled. A gas is not suitable for use if doesn’t generate the required heat or if it exceeds your set budget.

Flame cutting thickness range for steel plate

This is among the commonly asked questions when people are inquiring about the flame cutting process to cut steel plate or steel panels. As earlier stated, this process can be traced way back when industrialization was at peak. It is proven that this process cuts up to 100 inch material. It is evident this process simplifies material cutting task.

All thin material must be intensely preheated to enhance the cutting speed. Additionally, the preheating process improves the cutting process. This preheating process remains constant for all thick materials.

The point is, The thickness of the steel being cut depends on the amount of oxy fuel being delivered during the cutting process. The fuel gas and pure oxygen can be adjusted to deliver smooth cut surface, depending on a person’s needs.

Cutting temperatures

Generally the preheating process entails heating a material between 1600-1800 degrees F.
Secondly, pure oxygen is passed through the heated area to facilitate burning or oxidization. This is the reason a person can achieve an excellent final cut surface. It can be a sharp slag-free lower edge, sharp top edge or a flat cut surface.

How to get a quality flame cut steel panel with higher precision?

There are numerous factors that control the flame cutting process, so to get a quality flame cut steel panels or parts with higher precision. There are some factors we shall be noted:

• Carefully studying and understanding the working process. It is advisable to hire a professional service provider if you find this process difficult or stressful.

• Selecting a perfect tip for achieving your desired cuts. There are numerous tips people can use to achieve their desired results. Selecting a simple technique makes it easy to achieve your desired outcome.

• Choosing the correct oxy fuel cutting pressure. People have different needs. Choosing the correct oxygen pressure ensures you achieve your desired quality cut.

• Taking the preheating process seriously. Some people take this process lightly. The preheating process determines if the entire flame cutting process will be a success or not.

• Using the right cutting speed to achieve your desired goals within the set time frame.

There is no doubt the it can help people cut various materials into different shapes at a pocket friendly price. We shall note that not everyone attains a high quality or desired precision flame cutting parts, but with above notes at least you will not get a failed cuts.

About laser cutting

Laser cutting is to cut different materials especially steel metals with the help of laser beam. It is majorly used for industrial manufacturing applications, profiling metal connections for different equipment and structural parts. But now a day’s it also has been used for different purposes, such as wall art decoration, urban construction, auto-mobile manufacturing etc.

Why Laser cutting is getting popular in steel and metal cutting processes? Most is because of the reasons below.

Economic
High precision (up to +/- 0.05mm)
Rigorous cutting edge
Highly processing speed
Excellent cut quality
Less contamination
Auto and manually profiling options
CNC technology in
CAD connection
More material types
Small slot
Low transformations

Octal provide metal laser cutting services, which means we can cut steel plate, metal sheet as customized to different panels, screens, wall art etc. And before you are ordering this service, there are several things you need to know about laser cut metal technology.

Laser Cut Metal Material Types

What kind of material could be processed by laser cutting technology?

Yes, mostly laser cutting is used to cut mild steel (carbon and alloy steel) aluminum, stainless steel plates, metal sheets and other substances. We are listing steel material standard and grades for laser cutting so you can to decide what materials you prefer.

Cutting Thickness

Laser cutting method is best suited for cutting mild steel plate which has a thickness up to 1.25 inch (36 mm). After one inch, the cutting process will become difficulty and it need to be perfectly set which requires to configure each thing correctly. Like installing the material, checking the nozzle condition, beam quality, and gas purity. We know how to use laser technology to laser cut metal.

Laser cut metal tolerances

For different thickness of steels, different length and width tolerances standard will be applied, and normally as below:

• Steel thickness under 1.0mm, tolerances is +/- 0.12 mm.
• From 1.0 mm to 3.0 mm, tolerances allowed +/- 0.15 mm.
• From 3.0 mm to 6.0 mm, +/- 0.20 mm.
• 6.0 mm to 15.0 mm, laser cutting tolerances at +/- 0.25 mm.
• Up 15.0 mm to 20.0 mm, laser cut tolerances at +/- 0.75 mm.

Why laser cutting keeps material with precisely sizes

It’s not a fast process, especially on the mild steel, it looks like a burning process in which the extreme heat of the beam is used rather than the preheat flame. In this case, the speed is mainly maintained by keeping a check on the reaction of iron and oxygen. The precision of the laser cut metal is excellent. It creates a very tiny kerf width which helps in cutting even the precise contours as well as the small holes. With laser cutting, the edge quality is outstanding, with perfectly square edges and no or very little trash.
