Embodiment 1

[0030] Refer to attached figure 1 , a kind of soft-hard composite coating woodworking cutter of the present invention is a woodworking milling cutter, and the cutter matrix material is cemented carbide YG8N; From the cutter substrate to the cutter surface, they are: Cr transition layer, CrCN+CrN hard coating, CrN / WS 2 Buffer coating, CrN+Cr / Ni transition layer, Ni / nano-Al 2 o 3 / PTFE composite coating. It is prepared by the method of multi-arc ion plating + intermediate frequency magnetron sputtering, and the specific steps are as follows:

[0031] 1. Pretreatment: Mechanically polish the hard alloy of the tool base to remove the surface contamination layer, then put it in alcohol and acetone in turn, ultrasonically clean it for 15 minutes each time, and quickly put it into the vacuum chamber of the coating machine after it is fully dried. 6.0×10 -3 Pa, heat the substrate to 300°C and keep it warm for 40min;

[0032] 2. Ion cleaning: Ar gas is introduced, the air pressure...

Abstract

The invention provides a soft and hard composite coating woodworking tool and a preparing method thereof. The soft and hard composite coating woodworking tool comprises a tool base body and a tool coating arranged on the outer surface of the tool base body. The tool coating sequentially comprises a Cr transition layer, a CrN hard coating, a CrCN hard coating, a CrN/WS2 middle buffering layer, a CrN transition layer, a Cr/Ni transition layer and a Ni/Al2O3/PTFE composite coating from interior to exterior. The coating tool integrates characteristics of high hardness and high abrasion resistance of the CrN/CrCN hard coating, self-lubricating performance and good bonding performance of the CrN/WS2 middle buffering layer and good abrasion resistance and chemical stability and low friction coefficient of the Ni/Al2O3/PTFE composite coating, and the woodworking tool shows better cutting performance during wood and wood composite material cutting.

Description

technical field [0001] The invention relates to the technical field of cutting processing and manufacturing of wood and wood composite materials, in particular to a soft-hard composite coated woodworking tool and a preparation method thereof. Background technique [0002] Coating the tool is one of the important ways to improve the cutting performance of the tool. Tool coatings can be divided into two categories: hard-coated tools and soft-coated tools. The hard-coated tool is characterized by increased hardness and wear resistance of the tool, and the soft-coated tool is characterized by a reduced coefficient of friction between the tool and the cutting surface. Today, tool coating technology has been widely used in the field of metal cutting, but relatively less in the field of wood cutting. [0003] In the field of wood cutting processing, high-speed steel and cemented carbide are mainly used as cutting tools. Compared with metalworking knives, woodworking knives rotate...
