For novices, they will have difficulties when encountering poor cutting quality, and they do not know how to adjust when faced with many parameters. The following briefly introduces the problems encountered and the solutions.

The parameters that affect the cutting quality are: cutting height, cutting nozzle model, focus position, cutting power, cutting frequency, cutting duty cycle, cutting air pressure and cutting speed. The hardware conditions are: protective lens, gas purity, plate quality, focusing lens and collimating lens.

In case of poor cutting quality, it is recommended to conduct a general inspection first. The main inspection contents and order of the general inspection are:

  1 Cutting height (It is recommended that the actual cutting height is between 0.8~1.2mm). If the actual cutting height is not accurate, calibration is required.

  2 Cutting nozzle Check whether the model and size of the cutting nozzle are used incorrectly. If they are correct, check whether the cutting nozzle is damaged and the roundness is normal.

  3 For the optical center, it is recommended to use a cutting nozzle with a diameter of 1.0 for optical center inspection. When checking the optical center, the focus should be between -1 and 1. The light spot is small and easy to observe.

  4 Protective lens Check whether the protective lens is clean, it requires no water, no oil and no slag spots. Sometimes the protective lens may be fogged due to the weather or the air is too cold.

  5 Focus Check whether the focus is set correctly. If it is an automatic focusing cutting head, you must use the mobile APP to check whether the focus is correct.

  6 Modify cutting parameters

After checking the above five items and there is no problem, modify the parameters according to the phenomenon.

How to adjust the parameters according to the phenomenon, the following briefly introduces the conditions and solutions encountered when cutting stainless steel and carbon steel.

Such as stainless steel slag, there are many types of slag. If you only need to slag on the corner, consider rounding the corner first. In terms of parameters, you can reduce the focus and increase the air pressure.

If the whole body is covered with hard slag, it is necessary to reduce the focus, increase the air pressure, and increase the cutting nozzle. However, if the focus is too low or the air pressure is too high, it will cause delamination and rough surface. If the granular soft slag is hung on the whole, the cutting speed can be appropriately increased or the cutting power can be reduced.

Cutting stainless steel may also encounter: slag on the side of the cutting end, you can check whether the gas supply is insufficient and the gas flow cannot keep up.

Cutting carbon steel generally encounters problems: the section of the thin plate is not bright enough, and the section of the thick plate is rough.

Generally speaking, a 1000W laser can cut the brightness of carbon steel not exceeding 4mm. 2000W is 6mm and 3000W is 8mm.

If you want to cut the section to be bright, you must first have a good surface without rust, paint, and oxide skin, and secondly, the oxygen purity must be at least 99.5% higher. When cutting, you need to pay attention to: use a small cutting nozzle to double layer 1.0 or 1.2, cutting speed It needs to be faster than 2m/min, and the cutting air pressure should not be too high.

If you want a good cut section of thick plates, you must first ensure the purity of the plate and gas, and then select the cutting nozzle. The larger the aperture, the better the quality of the section, but at the same time the taper of the section will be greater.

Laser cutting technology has become most important part of the manufacturing process and hence it accounts for 70% of laser application industry. These high precision Laser cutting Machines have successfully made their mark on in market with their great set of features and totally ruled out the traditional cutting technologies. There is a multitude of benefits these Laser cutting machines provides but I will try to list few of them for you below:

Works with wide range of materials and thickness: Laser cutting possesses the ability to cut effortlessly through a wide spectrum of materials like stainless steel, carbon and mild steel, aluminum and aluminum alloys, copper, brass, bronze, titanium, timber, acrylic, rubber and fabric. It can cut through thicknesses of 0.5mm to 25mm

Precision repeatability: High precision Laser Cutting Machines provides easy and accurate repeatability to the model maker which is highly desirable in case of mass production.

Improved Edge quality: These machines provide very clean edges as compared to conventional methods. Due to non-contact nature of this process, no wearing is caused by the tool, no mechanical force is directly imparted on the part which prevents any kind of material distortion or workpiece contamination. Heat affected zone(HAZ) is also reduced.

Easy Maintenance: Industrial Laser Cutting Machine requires very inexpensive replacement parts like nozzles and lenses which make them easy and low maintenance systems.

Lower lead time: A single Industrial laser cutting machine can cut materials of almost any size, type and shape hence it provides very less lead time.It can generate 3D shapes and complex designs on any sort of material which is somewhat difficult for traditional cutting machines. A Laser Cutting Machine consumes less energy while cutting sheet metal.

Accurate results: A Laser Cutting Machine is totally computer programmable hence generate accurate results and offers a great amount of control to the user.

Fast: High precision Laser Cutting Machines are way to faster as compared to conventional cutting machines.

The business of Industrial Laser Cutting Machines is booming day after day. If you are also thinking about purchasing one for your manufacturing unit then Triumph Laser is a place for you. Triumph Laser provides a variety of laser cutting machines like Oxy Fuel, Nitro Fuel, Sublimation, Scanner, Kiss and Robotic cutting. A customer-centric approach of Triumph Laser compels them to take a step further and provide customized laser machines perfectly suitable for your application.
