Product Description
CHC-1000L independent capacitive height controller (hereinafter referred as CHC-1000L) is a high-performance capacitive heightening device that adopts close-loop control method to control the laser cutting head’s capacitive follower.
During laser cutting process, the distance between the nozzle and the workpiece surface is not constant due to the unsmooth workpiece and high-pressure gas injection when cutting, which has negative impact on the cutting performance and even damage the nozzle.
CHC-1000L height controller can keep distance between the nozzle and workpiece remain constant during fast laser cutting, so as to protect the nozzle from hitting workpiece and improve the cutting finishing. The capacitive sensor on the cutting head can detect the distance between nozzle and workpiece surface. It is sent to the regulator box for processing via preamplifier. Then the output signal is transmitted to the servo controller to control the Z axis.
By providing a unique Ethernet communication(TCP/IP protocol) interface, it can support many functions with CNC controller for laser cutting, such as automatic tracking of cutting height, segmented piercing, progressive piercing, edge seek, leapfrog, arbitrary setting of lift-up height of cutting head.
In terms of servo control, CHC-1000L adopts the double-closed-loop algorithm of speed and position, and its performance of running speed and precision is obviously better than that of similar products.
