I am selling imported laser machines, there is no standard for laser cutting quality at all, and each manufacturer's factory equipment is its own acceptance standard, believe me.

Tongfa Laser has the answer for you:

At present, there are six main standards for measuring the cutting quality of metal laser cutting machines:

1.How rough is the surface of the material being cut.

2.The size and quantity of the cut-out, burr, and hanging slag of the material after cutting.

3.Whether the angle of the edge of the incision is perpendicular and whether the slope is too large.

4.The size of the rounded edge of the cutting material.

5.Cut stripes are a measure of thickness.

6.Cut thick flatness.

7.Cutting thickness at the same power supply and the same power.

There are many national standards involving laser equipment. The following two criteria may be the closest to the requirements in the question.

GB Z 18462-2001 Laser Processing Machinery Performance Specification and Standard Inspection Procedures for Metal Cutting.

GB T 18490-2001 Safety Requirements for Laser Processing Machinery.

The external processing of each brand of laser cutting machine** is calculated according to the cutting meter (one meter of laser cutting cost).

The normal market algorithm** is:

1m of cutting** = thickness of material to be cut without material **). For example, when laser cutting 1 meter, use 61mm 1 meter of mild steel to compare the price: 6 (plate thickness) yuan meter.

10 (thickness) yuanm; 12 (thickness) Yuan meters, when laser cutting 1 meter, the determination of the specific ** is closely related to the number of parts that need to be processed, the shape of the parts (if they are all small holes, can not be calculated in meters), whether the freight is included, whether the material is used for processing, etc.

Calculated according to the hour: 400-1000 yuan per hour, which is affected by regional differences, because the region is different, its labor cost will be different, so there will be differences, but the floating is generally within this range.

Scope of application. Most laser cutting machines are controlled by CNC programs or made into cutting robots. As a precision processing method, laser cutting can cut almost all materials, including 2D cutting or 3D cutting of thin metal sheets.

In the field of automobile manufacturing, the cutting technology of space curves such as car roof windows has been widely used. Volkswagen AG of Germany uses a 500W laser to cut body sheets and various curved parts with complex shapes.

In the aerospace field, laser cutting technology is mainly used for the cutting of special aviation materials, such as titanium alloys, aluminum alloys, nickel alloys, chromium alloys, stainless steels, beryllium oxide, composite materials, plastics, ceramics and quartz. The aerospace parts processed by laser cutting include engine flame cylinders, titanium alloy thin-walled casings, aircraft frames, titanium alloy skins, wing girders, tail wall panels, main rotors, space shuttle ceramic heat insulation tiles, etc.

Laser cutting and forming technology is also widely used in the field of non-metallic materials. It can not only cut materials with high hardness and brittleness, such as silicon nitride, ceramics, quartz, etc.; It can also cut and process flexible materials, such as cloth, paper, plastic plates, rubber, etc., such as cutting clothing with laser, which can save 10% 12% of clothing and improve the efficacy by more than 3 times.

Laser processing** can generally be calculated in two ways:

One is calculated according to the hour, for example, how much does it cost to laser cut parts for 1 hour?

Generally, it ranges from 400-1000 yuan per hour, which is affected by regional differences, because the region is different, and its labor cost will be different, so there will be differences, but the floating is generally within this range.

The second is to calculate according to the linear meter.

Linear meter: It is the total length of a sheet metal part cut by laser. The length of the linear meter is generally measured directly with CAD. That is, per linear meter** = sheet metal thickness * 1mm thickness linear meter**.

For example, the laser cutting of 6 mm mild steel plate is equal to 6 (plate thickness) **) = 9 yuan meters.

1mm thickness of the meter** according to different materials, different regions, ** is different. For example, the ** of 1mm aluminum plate and 1mm carbon steel is different.

The unit price per meter is different for each sheet metal factory, and the unit price per meter is basically bottomed out when checking the number of meters.

Laser surgery**Myopia is currently divided into two main surgical methods, and the cost is different. The first is excimer laser surgery, which is the earliest surgical method for myopia, and the current cost of surgery is generally about 5000-8000 yuan. The second is femtosecond laser surgery, which is also the most widely used surgical method at present, compared with excimer laser surgery, the surgery is less invasive and more precise, so the surgical effect is better.

The cost of femtosecond laser surgery is generally about 18,000-20,000 yuan, and the cost of femtosecond laser surgery is generally about 8,000-12,000 yuan. If myopia is present in the eye, it can be corrected by the above two methods.

According to the thickness of the material and the material, it is the same, for example: the thickness of the stainless steel plate is generally 1 yuan, and the puncture is 1 yuan, of course, the charge is different in each place. Recommend a Foshan Haojun stainless steel, cutting thickness range, not only the most affordable, but also fast delivery.

According to different materials, different industries have different processing algorithms:

In the sheet metal industry, it is basically calculated according to the "number of punctures" plus "meters", and different plates have different **, such as copper and aluminum processing of the same thickness is more than 1 times more expensive than stainless steel processing. The same material has different thicknesses, mainly depends on the processing difficulty and man-hours.

In the word-making industry, it is mainly priced according to square processing.

1. Calculation method 1: The laser cutting processing fee is calculated according to the multiple.

Many companies calculate the cost, but according to the length of the cutting line, carbon steel plate per meter is generally a multiple of the plate thickness, that is to say, 4mm carbon steel plate per meter cutting fee = 4 * yuan meter. Here's how to calculate it in detail:

Cutting 1 meter of ** = the thickness of the material to be cut ** excluding material costs, the customer with material processing).

For example: 6 mm mild steel plate laser cutting 1 meter ** is: 6 (plate thickness) yuan meter;

8 mm mild steel laser cutting 1 meter ** is: 8 (plate thickness) yuan meter;

10 mm mild steel laser cutting 1 meter ** is: 10 (plate thickness) yuan meter;

According to this formula, it can be seen that the plates of different thicknesses are cut per meter.

The ** of stainless steel is different from the ordinary, the ** of stainless steel per meter is generally twice the thickness of the plate, and the ** of aluminum plate per meter is generally 4 times the thickness of the plate. At the same time, if the middle of the plate is to be cut, the perforation fee should be charged, and the perforation fee is generally different in yuan according to the different thickness of the plate. Of course, the specific ** has a lot to do with the size of the processing amount, the shape of the parts (the comparison is all small holes, it cannot be completely calculated by meters), whether it includes freight, whether it is processed with materials, etc.

2. Calculation method 1: Laser cutting processing is settled by the hour and there are regional differences.

Generally 400-1000 per hour, regional differences are also relatively large, Hefei, Zhejiang is cheaper, Beijing, Shanghai, Chongqing and other places are relatively expensive, this and your region has a clear difference, because the area of sheet metal materials and other ** is different, its labor costs are different, so ** will also be different, but ** floating must be within this range, but beyond this range.

The laser cutting machine is suitable for cutting materials:

a) Carbon steel plate cutting:

Modern laser cutting systems can cut carbon steel sheets with a maximum thickness of nearly 20mm, and the cutting seams can be narrow to about the thin plates. Laser-cut mild steel has a very small heat-affected zone, and the cut is smooth, smooth, and has good verticality. For high-carbon steel, the laser cutting edge is better than that of low-carbon steel, but its heat-affected zone is larger.

b) Stainless steel cutting:

Laser cutting is easier to cut stainless steel sheets. With the high-power YAG laser cutting system, the maximum thickness of stainless steel can be cut up to 4mm.

3) Alloy steel plate cutting:

Most alloy steels can be cut with a laser with good trimming quality. However, tool steels and hot die steels containing tungsten high will have erosion and sticky residue during laser cutting.

4) Aluminum and alloy plate cutting:

Aluminum cutting is a kind of melting cutting, and the molten matter in the cutting area is blown away by auxiliary gas, and a better cut quality can be obtained. Currently, the maximum thickness of cutting aluminum sheet is:

5) Other metal material cutting:

Copper is not suitable for laser cutting, and it is cut very thin. Most of the titanium, titanium alloys and nickel alloys can be laser cut.

Non-metallic laser cutting machine is a laser cutting machine that cuts other than metal, such as leather, cloth, handicrafts, acrylic, knife template, marble, electronics, etc.

The so-called non-metallic laser cutting is to melt and evaporate the workpiece by releasing the energy when the laser beam is irradiated on the surface of the non-metallic material to achieve the purpose of cutting and engraving, with high precision, fast cutting, not limited to the limitation of cutting patterns, automatic nesting to save materials, smooth incision, low processing cost and other characteristics.

Non-metallic laser cutting machine, is to cut metal other than the laser cutting machine, such as leather, cloth, handicrafts, acrylic, knife template, marble, electronics and other industries, these industries need laser cutting machine, and metal laser cutting machine is different, they need another kind of equipment, this equipment is non-metallic laser cutting machine, in the non-metallic laser cutting machine, each industry has its own laser cutting machine, is the most applicable, but those that are not suitable for the industry laser cutting machine, Those that do not belong to the metal industry all belong to non-metallic laser cutting machines.
