Green laser pointer light directivity

To take into consideration the quality of cut, cutting speed and other factors, in principle, 6mm metal materials, the focus is on the surface; 6mm carbon steel, the focus above the surface; Hualing green laser pointer company is one of the manufacturers with strongest production capacity.6mm stainless steel, the focus in under the surface. the specific size determined by experiment in industrial production in an easy way to determine the focus position in three ways: (1) Print method: the cutting head from the top down movement, the laser beam in the plastic sheet printing, print the minimum diameter focus at (2) ramp method: using and the vertical axis at an angle into a plastic plate to pull the level to find the smallest laser beam focus at (3) blue spark method: remove the nozzle, the air blowing , the pulse laser in a stainless steel plate, so cutting down on head movement from up to maximum at the focus spark blue for light path of the cutting machine, due to beam divergence angle, cutting the length of the proximal and distal processes of different time , pre-focused beam size there are some differences. the greater the diameter of the incident light beam, the smaller the focal spot diameter.Products of this green laser pointer company are gift-oriented. To reduce the beam size before the change in focus brought about changes in the focus spot size, laser cutting system, domestic and foreign manufacturers some special device for users to choose: (1) collimator, which is a commonly used method, that is the output of CO2 laser collimator to add a beam expander processing, the beam after the beam expander larger diameter, smaller divergence angle, so that within the scope of work in cutting the proximal and distal focused beam size close to the front line (2) increase in the cutting head of an independent movement under the lens axis, it nozzles to the surface and control the distance (stand off) and Z-axis are two independent parts when moved or machine table moves the optical axis, the beam axis from proximal to distal F also mobile, so that after focusing the beam spot diameter is consistent throughout the processing area Figure two shows (3) control the focusing mirror (usually metal reflector focusing system) pressure. There are more than ten production bases under the Hualing green laser pointer company.If the focus before leaving the focus of the beam spot size smaller diameter becomes larger, the automatic control of pressure to change the focus point of curvature spot diameter smaller (4) flying optics cutting machine to add x, y direction of the compensation optical system. that is, when cutting a remote optical path is increased to compensate for optical path shortened; the other hand when cutting near the optical path is reduced, so that compensation optical path to increase to maintain the same optical path length, cutting perforated thermal cutting any kind of technology, except for a few cases can be started from the edge of the board, in general, must wear a hole in the board. Earlier in the composite laser punching machine is the first punch out of a hole, and then laser cut from the hole at the start for not stamping device laser cutting machine, there are two basic methods of perforation: (1) blasting perforation: (Blast drilling), materials irradiated by continuous laser the formation of a pit in the center,Hualing green laser pointer enterprise has become a famous international company. then with the laser beam by the oxygen flow will soon remove the molten material to form a hole the size of the hole and the thickness is generally related to the average diameter of blast hole half the thickness, and therefore more thick plate blasting a large hole diameter, and not round, not in the higher parts to use (such as oil sieve slit tube), can only be used on waste.
