What is acrylic laser cutter?

acrylic laser cutter for sale

What is acrylic laser cutter machine?-acrylic laser cutter is a technology that uses a laser to cut materials, and is typically used for industrial manufacturing applications, but is also starting to be used by schools, small businesses, and hobbyists. acrylic laser cutter works by directing the output of a high power laser most commonly through optics. The laser optics and CNC (computer numerical control) are used to direct the material or the laser beam generated. A typical commercial laser for cutting materials would involve a motion control system to follow a CNC or G-code of the pattern to be cut onto the material.

The focused laser beam directed at the material, which then either melts, burns, vaporizes away, or is blown away by a jet of gas,leaving an edge with a high-quality surface finish. Industrial laser cutters are used to cut flat-sheet material as well as structural and piping materials. There are many different methods in cutting using lasers, with different types used to cut different material. Some of the methods are vaporization, melt and blow, melt blow and burn, thermal stress cracking, scribing, cold cutting and burning stabilized acrylic laser cutter. Vaporization cutting In vaporization cutting the focused beam heats the surface of the material to boiling point and generates a keyhole. The keyhole leads to a sudden increase in absorptivity quickly deepening the hole. As the hole deepens and the material boils,vapor generated erodes the molten walls blowing ejecta out and further enlarging the hole. Non melting material such as wood, carbon and thermoset plastics are usually cut by this method.

Melt and blow Melt and blow or fusion cutting uses high-pressure gas to blow molten material from the cutting area, greatly decreasing the power requirement. First the material is heated to melting point then a gas jet blows the molten material out of the kerf avoiding the need to raise the temperature of the material any further. Materials cut with this process are usually metals. Thermal stress cracking Brittle materials are particularly sensitive to thermal fracture, a feature exploited in thermal stress cracking. A beam is focused on the surface causing localized heating and thermal expansion. This results in a crack that can then be guided by moving the beam. The crack can be moved in order of m/s. It is usually used in cutting of glass. Stealth dicing of silicon wafers The separation of microelectronic chips as prepared in semiconductor device fabrication from silicon wafers may be performed by the socalled stealth dicing process, which operates with a pulsed YAG laser, the wavelength of which is well adopted to the electronic band gap of silion. Reactive cutting Also called “burning stabilized laser gas cutting”, “flame cutting”. Reactive cutting is like oxygen torch cutting but with a laser beam as the ignition source. Mostly used for cutting carbon steel in thicknesses over 1 mm. This process can be used to cut very thick steel plates with relatively little laser power.

How acrylic laser cutter work?

What is the working principle of acrylic laser cutter machine?-acrylic laser cutter machine is now the most advanced mechanical processing equipment, laser is first used in the field of mechanical processing, brought unprecedented promotion to the development of mechanical processing.

What is the working principle of acrylic laser cutter machine?-A lot of people to the acrylic laser cutter machine is not very understanding, most of whom were heard someone mentioned in the peer, but don’t know what was the basic working principle, let us give you a detailed explanation of the;

acrylic laser cutter machine is mainly composed of two parts, one is the CNC work station, another is the machine tools.We can pass the CNC work station, processing drawings will need input, after the operation, will conduct instructions to the machine tools, machine tools will be according to the instruction work out to sheet metal design.

The core part of the machine tool is one of the laser generator, it is the core of the whole equipment.Why do you say so?Because it is the secret of the cut metal device.It can convert electrical energy into light energy, release the remarkable feats of laser beam, and with a lot of energy, laser beam by irradiation in sheet metal surface, make the light surface quickly reaching high temperature, radiation surface melting and evaporation of components, through the displacement of the cutting head to achieve the purpose of cutting and engraving.

Generally there are many kinds of acrylic laser cutter machine laser, can according to different material to different kinds of acrylic laser cutter machine.We have in common solid laser material as medium, its representatives have solid YAG acrylic laser cutter machine.With gas as the medium of laser, its representative has CO2 acrylic laser cutter machine.Based on optical fiber laser medium, its representatives have optical fiber acrylic laser cutter machine.The three machining effect and the thickness is different.

What conditions acrylic laser cutter conditions work?

acrylic laser cutter machines can accurately produce complex exterior contours. The laser beam is typically 0.2 mm
(0.008 in) diameter at the cutting surface with a power of 1000 to 2000 watts.
acrylic laser cutter can be complementary to the CNC/Turret process. The CNC/Turret process can produce internal
features such as holes readily whereas the acrylic laser cutter process can produce external complex features easily.
acrylic laser cutter takes direct input in the form of electronic data from a CAD drawing to produce flat form parts of great
complexity. With 3-axis control, the acrylic laser cutter process can profile parts after they have been formed on the CNC
/Turret process.
Lasers work best on materials such as carbon steel or stainless steels. Metals such as aluminum and copper
alloys are more difficult to cut due to their ability to reflect the light as well as absorb and conduct heat. This requires
lasers that are more powerful.
Designed considerations Lasers cut by melting the material in the beam path. Materials that are heat treatable
will get case hardenedat the cut edges. This may be beneficial if the hardened edges are functionally desirable in the
finished parts.
However, if further machining operations such as threading are required, then hardening is a problem.A hole cut
with a laser has an entry diameter larger than the exit diameter, creating a slightly tapered hole.The minimum radius
for slot corners is 0.75 mm (0.030 in). Unlike blanking, piercing, and forming, the normal design rules regarding minimum
wall thicknesses, minimum hole size (as a percent of stock thickness) do not apply. The minimum hole sizes are
related to stock thickness and can be as low as 20% of the stock thickness, with a minimum of 0.25 mm (0.010 in) for
up to 1.9 mm (0.075 in).
Contrast this with normal piercing operations with the recommended hole size 1.2 times the stock thickness.
Burrs are quite small compared to blanking and shearing. They can be almost eliminated when 3D lasers are used
and further, eliminate the need for secondary deburring operations. As in blanking and piercing, considerable economies
can be obtained by nesting parts, and cutting along common lines. In addition, secondary deburring operations can be
reduced or eliminated.

How to choose acrylic laser cutter?

How to choose acrylic laser cutter machine?-Choosing appropriate acrylic laser cutter machine is very important.With the increasingly fierce market competition and the market demand for grade rising, such as metal acrylic laser cutter machine has been widely used. How to choose the suitable acrylic laser cutter machine?Here, the author try to solve this problem .As far as i am concerned,choose a suitable metal acrylic laser cutter machine generally depends on the production materials.Overall, the need to consider the following issues:

1.Cutting seam thin: acrylic laser cutter slot is in general 0.10mm-0.20mm.

2.The smooth cutting surface: acrylic laser cutter cutting surface without burrs.

3.The small deformation:laser thin slit, speed, energy concentration, therefore, to be cutting material on the small amount of heat, caused by the deformation of the material is very small.

4.Suitable for large products processing :Large products mould manufacturing cost is very high .Laser processing does not need any mould manufacturing .Laser processing completely avoid forming material punching the edge collapse, can greatly reduce the production cost of enterprises and enhance the grade of the product.

5.Very suitable for the development of new products, shorten the development cycle :Once the product drawings can be formed immediately ,then, laser processing can be done immediately .

6.Save material:Laser processing by computer programming can maximize the utilization rate of materials.

What is the advantage acrylic laser cutter machine?

There are quite a few advantages to laser cutters vs other processes.(I do feasibility studies for potential clients full time for a acrylic laser cutter machine builder, so I’ll try to explain without sounding biased) Typically, the alternative for a acrylic laser cutter process is a blanking press or a turret punch. A blanking press has a special cutting tool for each shape. A turret punch has a number of small tools and punches out a part by cutting a limited number of hole sizes and some line shaped blades for the outer edges. A laser cutter traces the outline of a part with the laser melting the metal, and an assist gas blasting the molten metal out of the cut.

Some advantages of a laser cutter:

1. Lower power consumption: a typical blanking press or turret punch consumes 50kW of power in total. A 4kW laser system uses 10kW of power total typically.

2. Safety: A blanking press has a large blade that moves rapidly up and down, and doesn’t necessarily have safety features to prevent a hand getting caught in it. A fiber laser is required to be enclosed by a light tight box which means they are designed to run without human intervention during cutting.

3. Material Scrap savings : Due to a cutting tool requiring material on either side of the cut, a border of at least 1/2 inch is required. For a laser, if parts share a common outline, they may be cut with a single cut, with no scrap. A minimal scrap skeleton may also be cut, as small as 1/16 of an inch or even less for some materials.

4. Cutting properties: a blanking die can only cut materials up to a maximum tensile strength. A laser can cut any strength of material, as long as the material can be melted.

5. Low maintenance: A blanking press or turret punch has expensive tools that must be sharpened and stored regularly as different parts are cut. A laser can change parts by changing programs, and requires relatively inexpensive replacement parts like lenses and nozzles.

6. Flexible operation: A traditional blanking line has a tool for each part that is a fixed design that is very high investment, typically costing somewhere on the order of $50,000 per tool, depending on the shape. A turret punch is somewhat better in that you can program any shape that can use that set of smaller shapes to make something, but if you want to change a dimension on a hole or something of that nature, design change is limited to the tools available, or a new tool must be purchased and it must replace an available slot on the turret. These tools are less pricey, but still require regular maintenance, which is a somewhat specialized task, so the labor costs will be higher. A laser can change the cutting profile on the fly, and typically takes less than an hour to reprogram, costing approximately $60 to apply a change, and that is a high estimate of the cost.

7.Improved edge quality: Since presses and punches are shearing through the material, which literally stretches the edge until it breaks, the top side of a part typically has a rounded over edge, while the bottom has a bunch of stretched ribbons that are very sharp. These are sometimes required to be cleaned off with an abrasive, which is a secondary process that adds to price. A laser, when properly focussed and set for a material, cuts a part with an edge with a mirror-like surface, the top edge remains square, and the bottom edge is smooth to the touch.

8. Faster changeover: A blanking press requires 30 minutes to change between cutting different parts, as the dies must be swapped out. A laser can change programs instantaneously, leading to time savings and allowing for smaller production runs to have a decreased price.

One slight negative to acrylic laser cutter lies in its method of profiling a shape. A blanking press cuts one whole part outline at a time. A turret press cuts one hole or edge for a part at a time. A laser must trace the entire part outline to cut a part. This slows the process somewhat, and causes the time to part completion to be longer. Still, for every 2 blanking lines, 3 laser lines can produce the same output. This means that since a blanking press costs $10 million, and a similar laser costs $2million, the investment in an additional machine still results in a lower price.

Hopefully this serves to highlight the advantages of a laser cutter, in an industrial setting.
