Method of laser metal cutting machine to determine the focal position

approach to determine the laser cut metal position Focus

an oscillating plate method using the vertical axis at a diagonal angle plates plastic pull horizontally find the minimum laser beam focus.

Two blue sparks France remove the nozzle, blow air, plate stainless steel pulsed laser cutting head up and down motion until blue sparks maximum attention.

3, the printing method the cutting head of the most popular sports in the plastic sheet laser printer, print the smaller diameter of the focus.

For optical cutting machine theft, due to the divergence angle of the beam, the cutting length of the proximal and distal end times differently, there are differences in orientation opposite of the beam waist. cost for stone crusher plantThe larger the diamequartz pulverising ball millter of the incident beam, the smaller the diameter of the focal spot. To reduce the beam size changes due to focus changes before the dot size Focus manufacturers laser cutting systems at home and abroad to provide special devices for users to choose ##

## (1) in the cutterhead By adding a separate axis of the lens, it is a control nozzle distance from the material surface (stand off) the Z axis of two independent parts . When moving the table of the machine or of the optical axis, the beam axis from the proximal end to the distal F also moves the diameter of the focused beam spot is constant throughout the zone job.

(2) smooth tube. This is a commonly used method, i.e., added to the output of a laser tube CO2 processing is expanded parallel light beam after the beam diameter of the beam expander is increased, the angle of divergence is smaller, so that the proximal end within the distal end of the scope and cutting Before discussing the beam waist in the vicinity of the same.
