Influence of TiN-coatings of hard alloy knives on exploitation of wood-cutting milling tool when processing laminated chipboard

Abstract

The influence of TiN-coatings surface of cutters mill wood tools on wear of cutters for milling special woods was investigated. The TiN-coatings were formed on surfaces of import cutting inserts of mill tools by the method of condensation from a plasma phase in a vacuum with ion bombardment of surface. The element composition coatings and tools, the surface morphology of cutting tools were studied by X-ray microanalysis and transmission electron microscopy. The phase composition of import cutting tools is a hard alloy with type of WC-3. The tools consist of double-blade cutters with TiN coatings for milling special woods showed growth of wear resistance by 20% in comparison with bare tools. There is abrasive chemical type of wear on surface coating of cutters mill tools.
