1. Is the operation of the home laser cutter machine dangerous?

Laser cutting is a very environmentally friendly cutting method, basically no harm to our health. Compared with ion cutting and oxygen cutting, laser cutting produces less dust, weak light and low noise. However, if you don't follow the correct operation method, it will also cause injury to the user or damage to the machine.

(1) Be careful of flammable materials when using the machine. Certain materials are not allowed to be cut on a home use laser cutter or a handheld laser cutter, including foam core materials, any PVC materials, and highly reflective materials.

(2) During the working process of the machine, the operator should not leave in order to avoid unnecessary losses.

(3) Do not stare at the laser processing operation. Do not watch laser through binoculars, microscope, magnifying glass, etc.

(4) Do not store explosive or flammable materials in the laser processing area.

2. What are the factors that affect the accuracy of home laser cutter machine?

There are many factors that affect the accuracy of home use laser cutter. Some are due to the equipment itself, such as the accuracy of the mechanical system, the degree of vibration of the worktable, the quality of the laser beam, the influence of the auxiliary gas and the nozzle. Some are inherent factors of the material, such as the physical and chemical properties of the material, and the reflectivity of the material. There are also some factors that are selected and adjusted according to the specific processing object and user quality requirements to determine the relevant parameters, such as output power, focus position, cutting speed and auxiliary gas.

3. How to find the focus of the home laser cutter machine?

Since the laser power density has a great influence on the cutting speed, it is particularly important to choose the focus position. The spot size is proportional to the focal length of the lens when the laser beam is concentrated. There are three simple methods to determine the cutting focus in the industrial field:

(1) Printing method: Move the cutting head from top to bottom, and print the laser beam on the plastic plate, and set the spot with the smallest printing diameter to the focus.

(2) Inclined plate method: Use a plastic plate placed obliquely at an angle to the vertical axis and pull it horizontally to find the smallest spot of the laser beam as the focus.

(3) Blue spark method: Remove the nozzle, blow air, hit the pulse laser on the stainless steel plate, and make the cutting head move from top to bottom until the blue spark appears.

Nowadays, many manufacturers' home laser cutter machines have realized automatic focusing. With the automatic focusing function, the processing efficiency of the home laser cutter machine can be significantly improved and the perforation time of thick plates is greatly reduced. When processing workpieces of different materials and thicknesses, the machine can automatically adjust the focus to the right position rapidly.
