How thick of wood can a 100 watt laser cut?

The laser cutting machine can't cut that thick. Generally, it's 16mm thick at most,

10 cm thick can be cut with water knife or flame cutting, CNC engraving machine

Maximum cutting thickness: 20mm


Stainless steel less than 4mm can be cut by laser cutting equipment. Carbon steel with thickness of 20mm can be cut by adding oxygen into laser beam, but thin oxide film will be formed on the cutting surface after oxygen cutting. The maximum thickness of cutting can be increased to 20 mm, but the dimension error of cutting parts is large.

The price of laser cutting equipment is very expensive, about 1.5 million yuan. However, due to the reduction of the cost of the follow-up process, it is feasible to use this kind of equipment in large-scale production. Because there is no tool processing cost, so the laser cutting equipment is also suitable for the production of small quantities of parts of various sizes that can not be processed originally. Laser cutting equipment usually adopts CNC device. After using this device, the cutting data can be received from CAD workstation by telephone line.


Laser cutting is to irradiate the workpiece with focused high power density laser beam to make the irradiated material melt, vaporize, ablate or reach the ignition point quickly. At the same time, the high-speed air flow coaxial with the beam is used to blow away the molten material, so as to realize the cutting of the workpiece. Laser cutting is one of the thermal cutting methods.


Laser cutting technology has the following advantages:

First, high accuracy: positioning accuracy 0.05mm, repeat positioning accuracy 0.02mm.

Second, narrow slit: the laser beam focuses into a very small light point, which makes the focus reach a high power density, the material is heated to the gasification level, and the evaporation forms holes. With the relative linear movement of the light beam and the material, the holes continuously form narrow slits. The incision width is generally 0.10-0.20ram.

Thirdly, the cutting surface is smooth: there is no burr on the cutting surface, and the surface roughness of the incision is generally controlled at ral2.5; Within a.

Fourth, high speed: the cutting speed can reach 10 m / min, and the maximum positioning speed can reach 70 m / M / N, which is much faster than wire cutting speed.

Fifth, good cutting quality: no contact cutting, cutting edge has little thermal effect, basically no thermal deformation of the workpiece, completely avoid the collapse of edge formed during material punching and shearing, cutting seam generally does not need secondary processing.

Sixth, do not damage the workpiece: the laser cutting head will not contact with the material surface to ensure that the workpiece will not be scratched.

Seventh, it is not affected by the hardness of the material to be cut: laser can process steel plate, stainless steel, aluminum alloy plate, cemented carbide, etc., no matter what kind of hardness, it can be cut without deformation.

Eighth, not affected by the shape of the workpiece: laser processing flexibility, can process any graphics, can cut pipes and other profiles.

Ninth, non metals can be cut: such as plastics, wood, PVC, leather, textiles and plexiglass.

Tenth, save mold investment: laser processing does not need mold, no mold consumption, no need to repair mold, save mold replacement time, thus saving processing costs, reducing production costs, especially suitable for large product processing.

11、 Material saving: the use of computer programming, can be different shapes of products for the whole plate material cutting, maximize the utilization of materials.

12、 Shorten the manufacturing cycle of new products: the number of new products trial production is small, the structure is uncertain and can be changed at any time, and the mold can not be produced at all. The laser cutting machine greatly shortens the manufacturing cycle of new products and reduces the mold investment.
