Laser cutting machine of edm

Laser cutting machine of the electrical discharge machining is a very complicated process, the micro process flow in a heat, manual, electric field force, magnetic force, such as electrochemical synthesis results. This process is mainly divided into the following son phases: interelectrode dielectric ionization, breakdown, and plasma channel is formed. Automatic adjustment device control tool electrode to be near workpiece slowly, is formed between the poles of the electric field increases with the decrease of the distance gradually, when the distance between the poles to appropriate discharge gap ( Usually the son microns to hundreds of microns) When, as a result of two electrodes on the surface of the micro uneven, lead to uneven electric field between the poles, the distance between two points near the electric field strength, the impurity in the working liquid medium ( Such as metal particles) And free electrons in the role of strong electric field, impact ionization, form a negatively charged and positively charged particles, charged particles after reaching a certain number working liquid medium ionization and breakdown, formation of plasma channel. Laser cutting machine of the channel between medium ionization to eliminate. After a pulse discharge, retained for a period of time interval, to rid the ionization of channel between medium, charged particles back to neutral particles, waiting for the start of the next pulse discharge, discharge in a timely and effective manner at the same time be removal in down metal particles, carbon particles and bubbles, etc. Therefore, in order to guarantee the normal electrical discharge machining progress, must have enough between two pulse discharge pulse interval, its size adjusted on the basis of the condition of the processing, the length of the pulse interval of time affects the processing quality and processing efficiency.
