CNT-1000 Profiling/Grooving/Polishing Machine with One Rotating Z-Head

In 1997, CNT Motion Systems designed and built the first of five machines for a customer specializing in the management of water removal and sheet formation on all types of pulp and paper machines. Their unique process combines heat and air flow to remove moisture content from pulp. Currently, they have five CNT machines (three in the U.S. and two in the APAC region) used for profiling reinforced fiberglass plastic 2" tall, 4" wide and up to 35' in length. Once machined, 2" ceramic profiles are bonded to the material and (using the same machine) ground to within .002" tolerance over the entire length and then polished to a #5-8 finish.
