Applications of Laser Cutting Machines

Laser cutting machines are used to cut materials with precision. They are used in almost all industrial operations needing cutting, drilling and boring either metal, plastic or paper. These machines are flexible to operate and enable high quality and perfect precision cutting facility.

The laser cutting technique applies high frequency of energy generated by laser beams focused at the point of the object that is to be cut. It is operated with the guidance of a computed process. Through this application of the laser cutting machine, the material melts out, burns or vaporizes away as per requirement. It is also capable of blowing away the molten material from the place with the power of high speed gas.

Different types of laser techniques are used for different types of applications in laser cutting machine. Gaseous CO2 laser is used for cutting, boring or engraving applications of metals, plastic, paper, wood, wax or fabric. Nd (Neodymium) laser is used for boring and welding where high energy is required. Another popular high power laser Nd-YAG (Neodymium-Yttrium-Aluminium-Garnet) is used for boring, engraving, trimming and welding purposes of metals and ceramics where very high frequency of energy is required.

Laser Cutting Machine

Different types of cutting techniques are applied by laser cutting machines for different purposes.

* Vaporization Cutting Technique: In this method, the material is heated to burning point to make a hole. As the heat gets more easily absorbed by the hole, it gets widened. When it reaches the boiling point, vapour gets generated which in turn thrusts out the ejected material from the hole. This application is employed for cutting non melting materials such as wood and non-melting plastic like thermoset plastic and carbon plastic.

* Melt and Blow Technique: This method involves heating the material up to melting point and then blowing out the molten material with high pressure gas. This application is mostly used for cutting metals.

* Thermal Stress Cracking Technique: This technique is applied for cutting of glasses. Glass is highly sensitive to thermal fracture. When heat is concentrated at a particular point on the glass, it gets expanded. Due to expansion, it cracks and gets separated from the other part.

Other applications of laser cutting machines include stealth dicing cutting for dicing of silicon wafers in electronics field and reactive cutting for cutting of thick steel plates using very nominal laser power.

Know Before Buying Bending Equipments

There are different types of bending equipments used to bend metal sheets, tubes, pipes and so forth. Today most of the industries utilize these equipments to increase the speed and productivity of the work process. Metal bending equipments can be bought easily from online stores as there are huge varieties of such equipments listed in most of the online stores. However, it is essential to remember a few facts before selecting bending equipments.

Tips to Select Bending Equipments

Basic features: It is important to consider the features of the bending equipment before choosing to purchase it. Bending equipments include a variety of features. It is important to consider the size of the metals that can be bent in these machines. Choose machines that can bend large sized tubes or metals.                                                                                                                            

Warranties: Some of the manufacturers offer warranties for these equipments. Some dealers also offer equipments on lease so that it can be utilized accordingly. Spare parts are also offered by some of the companies.

Prices: Different bending equipments are available at different price rates. As different machines include various features and specifications, the prices also vary accordingly. Moreover, these days there are a number of companies that manufacture different types of machines at different price rates. So it is quite important to compare the price rates of various equipments sold by various dealers before purchasing these machines.

Expensive: Most of the bending and cutting machine are quite expensive compared to the other types of machines. Although it is greatly beneficial to companies that manufacture metal products, the equipment is quite expensive and includes huge after expense. As these machines are expensive, it must be insured for a huge amount.

Common Benefits

There are many benefits of using bending equipments as it is quite profitable to the companies. It proves to be quite economical to the companies as work can be completed quickly and efficiently in the premises of the industry without outsourcing the projects. Safety is another important benefit of using these equipments. Work can be done mechanically without involving manual labor. All the products manufactured with the help of these equipments are well above par and in great demand.

Purpose of Plasma Cutting Machines

Although there are different types of cutting machines, the most commonly used cutting machine includes the plasma cutters. The plasma cutters are mainly used to cut metals into various shapes and sizes. Metal components are essential to build various types of tools and other materials such as suspension bridges, cranes, robots, sky scrapers and so forth. So there is a constant requirement for precisely cut metals which are both strong and sturdy. The plasma cutter is perhaps the only tool which can be used to manipulate and cut metals to desired shapes.        

Working Procedure of Cutting Machine

It is quite difficult to cut metals in various shapes with saws and other machines as metals have the immense power to resist any kind of damage. The need for precise cutting machines rose during the Second World War. Factories which manufactured war aircrafts used an innovative method of welding which involved the use of an inert gas supplied through an electrical arc. This method was further modified by changing the type of gas used for welding purposes.

Later, scientists discovered that temperature of the gas could be increased by boosting the speed of the gas flow. With the use of high temperature, this tool became a cutter rather than a welder. This discovery led to the plasma cutter which can be used to obtain precise lines in the joints.

With the discovery of the plasma cutting machines, the speed, type of cutting and the accuracy of the machines was completely revolutionized. As these cutters have a number of advantageous features, it is widely used in most of the industries and factories to cut metals into desired shapes and sizes.

CNC Plasma Cutter

The fast paced development of science and technology has further altered the working procedures of the plasma cutter. It is now numerically controlled by computers. Today, the CNC plasma cutters are quite efficient in cutting metals quickly and precisely.

With the help of the CNC plasma cutters, it is possible to arrange the metals and view it on the computer screens. It is possible to cut the metals precisely with these computer controlled equipments quite efficiently and quickly.
