When cutting a large plate with a smaller diameter cutter, it requires multi-pass cutting, and when the cutting-pass is increased, the machining time becomes even longer. Also, the multi-pass cutting can leave ridges between the cutting tracks, which requires highly skilled programmers to run the machine.
This machine is equipped with a large ” ( mm) diameter cutter, which enables the one-pass cutting of up to ” ( mm) in width, eliminating the ridges that are made with cutting with the smaller diameter cutter.
