Laser cutting machine to improve smoothness of measures

by：Transon 2020-10-27

Laser cutting machine for single discharge control of the indentation size is relatively easy, only need to reduce the single pulse energy. Only a single pulse energy to a certain degree of thicker workpiece cutting motionless, even a short circuit is not only the no spark discharge state, this is similar to fine gauge of edm, result in low efficiency, unstable processing chip removal ability is poor. And due to discharge of RZ and pits of the reversing stripe RZ is beyond the scope of the same order of magnitude, so control with reversing the RZ of stripe is important. Guide roller, the precision of the bearing, fluctuation of tension in the constancy and other reasons, cause the wire and the trajectory is inconsistent, this is the main cause of reversing the concavo-convex mechanical factors. Will take the following measures, to a certain extent, improve the finish: 1, decrease the pulse width and peak current, which reduce the size of the corrosion pit. 2, roller bearing and maintain good accuracy and stability of operation, reduce the wire, wire jump, keep the wire trajectory a line to a small amount of deflection. Maintain proper tension 3, silk, and adjusted the idler pulley and into the electric block, make silk upward downward, tension in the work place remain unchanged. 4, silk shoulds not be too tight, water shoulds not be too new, new water is good for cutting efficiency is sure, but not cutting finish new water well. 5, a thin workpiece upside down to add a piece of plywood, make the reversing stripes within the scope of the plywood is buffered.
