21C is producing various cutters and blades based on 30 years of technology and know-how.
Cutters required for cutting at various production fields, such as MLCC, film, and secondary batteries, are not simply cut, but precise straightness, angle management of the cutting edge, and excellent material management are required in order not to damage the object.
In general, cutters are classified into various categories such as blade, cutter, knife, vertical blade, wheel cutter, and the core technology, Edge’s management technology, is the core technology point of cutters.
Accordingly, the 21st century is supplying reliable high-precision, high-quality, long-life various cutters.
