Everything You Need to Know About Laser Cutting

Laser Cutting is a modern technology that is used to cut metals or any other material with perfection. To cut material, a focused beam of the laser is used for melting the material where it needs to be cut. To create a kerf the molten material is ejected to through a co-axial gas jet. To produce a continuous cut, one has to move either the laser beam or the workpiece under the CNC control.

The Characteristics Of Laser Cutting Are As Follows:

  • Laser cutting can help to cut carbon manganese steels which are up to 20mm thick.
  • The technique can be used to cut stainless steels which are up to 12 mm thick.
  • Brass and titanium can easily be cut with the help of laser cutting.
  • Laser cutting can help to reduce aluminum up to 10 mm thick.
  • With the help of laser cutting, one can cut wood, thermoplastics and a variety of other non-metals.

Different Types of Laser Cutting

There are three groups into which laser cutting is classified:

  • Fusion cutting: Fusion cutting is usually done with the help of inert gas. Mostly nitrogen is used as the inert gas. Nitrogen is used in the procedure because the nitrogen gas doesn’t come into reaction with the molten material exothermically and therefore, there is no energy input.
  • Flame cutting: In this kind of laser cutting, the assist gas which is used is oxygen. Oxygen not only exerts mechanical force on molten material, but it also creates an exothermic reaction that helps to increase the input of energy to the procedure.
  • Remote cutting: In this kind of laser cutting, the only high-intensity laser beam is used to partially evaporate the material. This makes it easy to cut the thin sheets without the help of an assist gas.

Some of The Benefits of Laser Cutting Are As Follows:

  1. The laser makes a precise and perfect cut. One doesn’t need to spend extra time taking care of the finishing.
  2. It is highly flexible. Be it a simple cut or a complex cut both can be done with super ease.
  3. The technique doesn’t require direct contact; therefore, there are no chances of surface blemishes.
  4. The amount of heat input is low.
  5. Almost all the metals can easily be cut with the help of laser cutting.

Lasers That Are Used For Cutting Metal Sheets

These days, most of the industrial metal sheets are cut with the help of lasers. These lasers are mainly of two types: fiber and CO2.

  1. Fiber lasers: They belong to the family called “solid-state lasers”. In this kind of lasers, the beam is produced by a medium which is solid. A number of laser diodes produce the beam. To amplify the energy of the laser is transmitted through an optical fiber. The beam, after being amplified, exits the optical fiber and then collimated and focused on the material which is to be cut.
  2. CO2 lasers: In this laser, the laser is generated with the help of a mixture of gas which consists of CO2, nitrogen and helium. This kind of laser is pumped electrically with the help of an electric discharge. A CO2 laser can efficiently cut materials which are thicker than 5mm. They are much more efficient as compared to fiber lasers which have the same power.


Laser cutting is a technique which is very easy, fuss-free and efficient. Due to all these advantages over traditional and other cutting techniques, laser cutting technique is gaining immense popularity.


Why Would You Use Vacuum Booster to Operate Your Machines?

Brakes are a crucial part of any of the vehicle. Without a break, there would be absolutely no way of stopping or hindering the run of a vehicle or machine. To overcome this problem, the machine was fitted with a certain mechanism which can stop the machine according to your needs. The idea was to use a pedal of sorts, which amplifies the power applied on it and sends the power applied as an opposing force to the working of the machine, thus making the machine stop. One such advancement in the field of brake development is a vacuum booster.

What is A Vacuum Booster?

These are nothing but a system developed to reduce the effort needed to be applied on a break for it to work and stop the machine. The system works on the principle of using a vacuum to suck out air in the chamber when force is applied. Apart from the cars, you can also find such systems in major machines and you can use the same to operate the machines smoothly.

What Are the Features of A Vacuum Booster?

  • Essentially the vacuum booster is nothing but a fluidless pump. There are multiple pumps available that use fluid to lubricate and amplify force. These boosters use the vacuum to do the same, in a more efficient way.
  • Since it uses the vacuum, there is very little friction which leads to low power consumption, when it comes to working at high speeds and greater volumes. The normal speeds of these boosters under high pressure can go up to 25-30 times faster than a vane pump or a ring pump.
  • In the range of 0.001 torrs, these boosters can be used to generate huge vacuum and volumetric speeds of a high level in low pressure. Fluid based pumps like water ring pumps will not be able to maintain high pumping speeds when they try to approach the ultimate levels.
  • The Mean Time between Failures, also known as, M.T.B.F in these boosters is long and these have a service life of an additional 7 to 10 years. No regular maintenance is needed unlike the ones need in other valves, which consists of different parts like valves, stuffing boxes, rings, etc. these parts often get damaged due to constant wear and tear.
  • One can use electronic control devices to modify the vacuum booster and alter its characteristics according to their needs. An example of such an electronic controlling device is a VFD or a Variable Frequency Device. These devices can be easily integrated into boosters.
  • These boosters can prove to be very power efficient. When these are combined with a prime pump, the pumping would require lesser power per unit of pumping speed. Therefore, this enables them to provide high pumping speeds at less pressure. You can also save your power and fluid consumption by using the vacuum booster.
  • The vapor compression done by the booster causes a constant high pressure at the discharge end of the booster or the inlet of the pump. If the booster is being used with a pump, a condenser might be needed to trap any vapors that escape during the process. This makes sure that the prime pump is free of any vapors and thus making sure the life of the pump and booster is extended and well kept. This also maximizes the efficiency and minimizes the frequent change of oil.

The features of boosters have been listed in the points above. Keeping these points in mind, one will know whether they need a vacuum booster to be a part of their project or not.

Few Applications Of CNC Plasma Cutting Machine

A CNC plasma cutting machine is widely used and its applications are highly in demand in the metal industry, as this is always better in terms of efficiency and speed as compared to a manual cutter.
