A simple method to metal processing sheet metal laser cutting machine

Many industries need for sheet metal processing, so it is inevitable to woke up sheet metal cutting. The sheet metal and metal laser cutting machine is cutting good tools. The metal laser cutting machine processing sheet metal is there any easy way?

Metal laser cutting machine at the time of processing sheet metal to determine positioning is very important, there are three: the simple method for determining

1, the printing method: make the cutting head movement, down on laser print on the plastic sheet, print small diameter as the focus.

2, inclined plate method: use and a vertical axis Angle inclined put plastic board makes its level, find the minimum place to focus laser beam.

3, blue spark method: remove the nozzle, blowing air, will play on stainless steel plate, the pulse laser makes the cutting head from the top down movement, maximize until blue sparks as the focus.

Flying light path of the cutting machine, as a result of beam divergence Angle, cutting the proximal and distal time path length is different, focusing the beam size before have certain difference. The diameter of the incident beam is larger, the smaller the diameter of the focal spot. In order to reduce the focus beam size change before the change of the focal spot size, domestic and foreign manufacturers of laser cutting system provides some special device for users to choose:　

1, parallel light pipe, it is a commonly used method, namely at the output of the CO2 laser beam expander of parallel light pipe processing, expanded beam after the beam diameter, divergence Angle smaller, so in cutting work within the scope of the proximal and distal focused beam size close to agreement before.

2, increase in cutting head under a separate mobile lens axis, it and control the nozzle to the material surface distance (standoff) of the Z axis is part two independent of each other. When the machine table to move or optical axis direction, the beam from the proximal to distal F axis move at the same time, also make the light beam focusing spot diameter after consistent throughout the processing area.
