What Are the Best Tips for Making Laser Cut Leather?

The two-head mutual-moving laser cutting machine uses a crawler-type work platform. The dual-laser head mutual-shift processing combines with an automatic discharge system, which has fast cutting speed and high fabric utilization. It can also be equipped with an automatic feeding system to achieve continuous feeding and cutting. For cutting of plush materials, composite fabrics and other materials.

Application industry: shoe materials,

Applicable materials:

1. The laser cutting of leather is narrow, and the deformation of the workpiece is small.

The laser beam of the leather laser cutting machine is focused into a small light spot, so that a high power density is achieved at the focal point. At this time, the heat input by the light beam far exceeds the part that is reflected, conducted or diffused by the material, and the material is quickly heated to the degree of vaporization, and the holes are formed by evaporation. As the light beam and the material move relatively linearly, the hole continuously forms a narrow slit. The cutting edge is little affected by heat and there is almost no deformation of the workpiece.

An auxiliary vapor suitable for the material to be cut is added during the cutting process. When steel is used for cutting, oxygen is used as an auxiliary vapor to generate an exothermic chemical reaction with molten metal. It also helps to blow away the slag in the cutting slot. Compressed air is used to cut plastics such as polypropylene, and inert vapor is used to cut flammable materials such as cotton and paper. The auxiliary vapor entering the nozzle can also cool the focusing lens, preventing smoke and dust from entering the lens holder to contaminate the lens and cause the lens to overheat.

Most organic and inorganic materials can be cut with a laser. In the metal processing industry where industrial manufacturing systems take a large part, many metal materials, regardless of their hardness, can be cut without deformation. Of course, for highly reflective materials, such as gold, silver, copper, and aluminum alloys, they are also good heat transfer conductors, so laser cutting is difficult or even impossible.

Laser cutting of leather has no burrs, wrinkles and high precision, which is better than plasma cutting. For many electromechanical manufacturing industries, because modern computer-controlled laser cutting systems controlled by microcomputer programs can easily cut workpieces of different shapes and sizes, it is often preferred over punching and stamping processes; although its processing speed is slower than die punching, But it has no mold consumption, no need to repair the mold, and saves the time to replace the mold, which saves processing costs and reduces production costs, so it is more cost-effective in general.

2. Leather laser cutting is a non-contact processing with high energy and good density controllability.

After the laser beam is focused, it forms a small action point with extremely strong energy. There are many characteristics for applying it to cutting. First, the laser light energy is converted into amazing thermal energy, which is kept in a very small area, which can provide

(1) Narrow straight edge slit;

(2) the smallest heat-affected zone adjacent to the cutting edge;

(3) Minimal local deformation.

Secondly, the laser beam does not exert any force on the workpiece, it is a non-contact cutting tool, which means

(1) No mechanical deformation of the workpiece;

(2) There is no tool wear, and there is no question of tool conversion;

(3) The cutting material does not need to consider its hardness, that is, the laser cutting ability is not affected by the hardness of the material being cut. Any hardness material can be cut.

Thirdly, the laser beam is highly controllable, and has high adaptability and flexibility.

(1) It is convenient to combine with automation equipment, and it is easy to automate the cutting process;

(2) Because there is no restriction on cutting the workpiece, the laser beam has unlimited contour cutting ability;

(3) Combined with a computer, the whole board can be discharged, saving material.

3. Leather laser cutting has wide adaptability and flexibility.

Compared with other conventional processing methods, laser cutting has greater adaptability. First, compared with other thermal cutting methods, the same as the thermal cutting process, other methods can not act on a very small area like a laser beam, resulting in wide cuts, large heat-affected areas, and obvious workpiece deformation. Lasers can cut non-metals, while other thermal cutting methods cannot.
