The laser cutting machine is an advanced equipment that utilizes laser beams to cut various materials. It’s mainly composed of two parts: a CNC control system and a machine tool.
You will get efficient and thoughtful service from SIEME.
So, how does the laser-cutting machine get the job done?
First, an operator needs to input the designed drawing into the CNC system which will deliver instructions calculated into the processing machine tool.
Due to the relative movement of the cutting head and the workpiece, lined and narrow cutting silts are formed to finish the cutting.
Laser-cutting machines are widely used in metal processing, aerospace, vehicle manufacturing, and other fabrication industries.
It can cut materials like carbon steel, stainless steel, aluminium alloy and titanium alloy, wood and acryllics. It can cut, engrave, punch holes, and weld.
However, to ensure its performance, daily maintenance is important. By virtue of its advanced processing quality and wide application spheres, the machine emerges as one of the most crucial equipments for morden manufacturing.
The selection of laser cutting machines directly decides productivity, product quaity, costs and market competitive forces for a manufacturing enterprise.
Therefore, the intelligent selection of laser cutters paves the way for the opportunity to win in market competitions and sustainable development.
Thus, metal processing companies and individuals interested in laser cutters should value all kinds of factors including laser powers, materials to be processed, automatization, cost-effectiveness, after-sale services based on personal demand so as to choose the most suitable one.
When purchasing laser cutters, some of the key elements as follows should be considered:
Suitable laser type and power are crucial. Different materials suit different types:
CO2 laser cutters are suitable for non-metal and thin metal plates with power ranging from 10W to W.
Fiber laser cutters are suitable for cutting metals by virtue of faster speeds with power ranging from 500W to W.
Relatively thin carbon steel and stainless steel can be cut by low-power fiber lasers(100W-2.5kW), while thick materials require more power.
Copper, grass, and other highly reflective materials require fiber lasers that are powered by over w.
Therefore, the most economical and efficient laser type and power should be selected based on the materials to be processed and their thickness.
The size of the cutting table decides the range of processing sizes.
The too small size of the table will limit the workpiece sizes, resulting in lower productivity; too large will occupy extra rooms, and higher costs.
Therefore, it’s essential to select proper cutting table sizes according to production shapes and sizes.
Cutting speed and precision directly influence the productivity and quality of products:
The speed of fiber laser cutters exceeds 30m/min, faster than CO2 lasers. High-power and quality laser cutters can reach higher levels.
Besides, their positioning accuracy should be controlled within 0.05mm and repeat accuracy within 0.03mm. What’s more, the speed and accuracy should be balanced so that the accuracy will not be reduced as a result of pursuing speed.
A laser cutter should be capable of processing various common metals and non-metals.
Carbon steel, stainless steel, and aluminum alloy are the most common metals. They should be capable of cutting highly reflective materials, like copper and grass, and hard-to-machine materials, like titanium and nickel.
In addition, other non-metal materials should also be taken into account, such as wood, acrylic, and textile. The more compatible the machine is, the higher utilization is the machine.
Automation and additional features are beneficial to improve productivity and product quality. Here are some of the advantages I wish to explain to you:
First, automation contains functions of automatic focusing, auromatic edge seeking and automatic avoidance, which greatly reduuces the labor inference. Automaric loading and unloading system allows for labor free production.
In addition, automatic height adjustment and an anti-collision device can prevent the cutting head from being damaged.
Double-platform alternating operation improves cutting efficiency. Thus, it’s important to choose the most valuable functional combination based on actual dimensions.
It’s widely believed that brand reputation and customer support matter when choosing products. The reasons are explained as follows:
Premium brands ensure equipment quality and stability so we should corporate with manufacturers who boasts profund technology strengths and independent intellectual property rights.
What’s more, brands with reputation have comprehensive trainning and necessary after-sale services, including maintenace and fault response. They can also ensure long-term supply for prone-worn workpiece and components.
