During the process of sheet metal cutting, if there is a need to constantly upgrade and change the mold, then a high-performance laser cutting machine will be a better choice!
There are two types of laser cutting techniques: one is the pulsed laser for metal materials. The other is the continuous laser application for non-metallic materials, which is an important application of laser cutting technology.
In many cases, laser cutters are the preferred tool when cutting metal and non-metallic materials. Laser beams can cut almost any profile quickly and flexibly, no matter how fine and complex the shape is or how thin the material can be. Different types of cutting gases and pressures can affect the process and results.
Compared with the traditional acetylene, plasma and other cutting processes, laser cutting is faster, makes a narrower cutting seam, the thermal impact area is small, good verticality of the cutting seam edge, smooth cutting edge, and can laser cut numerous types of materials, including carbon steel, stainless steel, alloy steel, wood, plastic, rubber, fabric, quartz, ceramics, glass, composite materials, etc. With the rapid development of the market economies as well as science and technology, laser cutting technology has been widely used in automotive, machinery, utilities, metal, electronics industries and many other fields. In recent years, laser cutting technology is developing at an unprecedented rate, with an annual growth rate of 15% to 20%.
1.1. First, have a clear idea of the production scope, types and thickness of the material that are being processed so as to be able to determine the model/s, processing plate size and quantity of equipment to be purchased. This is the groundwork for purchasing. Applications of laser cutting include for mobile phones, computers, sheet metal processing, metal work processing, electronics, printing, packaging, leather, clothing, industrial fabrics, advertising, craftwork, furniture, decoration, medical equipment and many other industries. The mainstream models on the market are 3015 and 2513, which is equivalent to 3 meters by 1.5 meters and 2.5 meters by 1.3. Generally the size of the processing plate is not a problem since many companies can supply a wide range or customised it according to their customers’ needs.
2.2. Professionals can carry out on-site simulation or provide solutions. In addition, they can also bring in their own materials to make samples at the manufacturer’s site.
1) Fine cutting seam: laser cutting seams are generally 0.10mm-0.20mm;
2) The cutting surface is smooth: the laser cutting surface has no burrs; YAG laser cutting machines generally have more or less some burrs, as this is dependent on the material thickness and the gas used during cutting. Usually, a thickness of less than 3mm does not result in burrs. For the gas, nitrogen has the best results, followed by oxygen and air is the worst. Fiber laser cutters have the fewest or no burrs, resulting in an exceptionally smooth cut surface and is amazingly fast.
3) Deformation of the material: the deformation of the material is very little
4) Power size: if the factory mainly cuts metal sheets that are less than 6mm, there is no need to buy a high-power laser cutting machine as a 500W fiber laser cutting machine can meet the production demand. If the production volume is large and there are concerns that 500W efficiency is not enough to cope with the demand, the best option is to buy two or more small and medium-power laser cutting machines so that it is cost efficient and production efficiency can be improved for manufacturers.
5）Laser cutting core parts: the lasers and laser heads, can be imported or domestically produced. Imported lasers are generally produced by IPG whilst domestic lasers are normally produced by Raycus Laser. Customers should also pay attention to the laser cutting accessories used, such as if the motor is a imported servo motor, the rails, the processing body and so on. These can affect the cutting accuracy of the machines. Special attention should be paid to the cooling system of the laser cutting machine – the cooling cabinets. Many companies use home air conditioning systems for cooling, which produce extremely poor results. The best way is to use industrial air conditioning which are dedicated professional systems that achieve the desired results.
3.Equipment that are being used will have wear and tear over time. For machine maintenance and repair, timely response and costs are key considerations. Hence, it is important to learn and understand, through different channels, on how good the supplier’s after sales service is, such as if the service costs are reasonable.
