Cutting Technology of Laser Slotting Screen

Laser slit sieve single ladder stitching is the whole root of the root incision, from the incision procedure, single slit incision is a subroutine. The whole root of the laser slotted screen by a certain law spread thousands of slits, rotary head rotation or channel displacement to complete the seam between the circumferential positioning or axial positioning, and then call the subroutine, cut out one by one Each seam. Is the axial rows of cut - a circle around the circumference to cut or cut in other order, are directly related to the effect of incision. Taking into account the process of cutting the tube heat transfer and lumen heat, or the entire root tube dividend several paragraphs, the axial row to cut better.
Laser cutting slot screen trapezoidal seam reached a high skill index: seam width: 0.15-0.05mm; trapezoidal angle: 0-40 °, cut surface roughness less than 6.3um; heat affected hardened layer: thickness greater than or equal to 0.3mm ; Hardness: greater than or equal HV800, enhanced wear resistance and corrosion resistance, improve the number of life. Slotted screen trapezoidal seam structure to overcome the sand seam blocking rectangular scene, a strong self-cleaning effect, that is, into the cavity in the sand, it is simply washed away by the fluid. Therefore, this slotted screen pressure loss is small, high output value, long life, low cost, and promote the progress of oil vocational skills and benefits.
