Abstract

The invention relates to the technical field of production of hard alloy numerical control coating inserts, and specifically discloses a cleaning method for hard alloy numerical control inserts before coating. The cleaning method is as follows: preparing No. 1-5 cleaning liquids suitable for WC-Co type hard alloy CNC insert substrates, and cleaning the surface of the coated substrate through an improved ultrasonic cleaning process; the No. 1 cleaning liquid is a powerful Alkaline metal cleaning solution; the No. 3 cleaning solution is a weak alkaline metal cleaning solution; the No. 5 cleaning solution is a cleaning solution containing antioxidants; the No. 2 and No. 4 cleaning solutions are pure water. The invention adopts No. 1-5 cleaning liquids and an improved ultrasonic cleaning process, which can ensure the cleanliness of the surface of the coating substrate, improve the production efficiency, and at the same time, it can also ensure that the surface of the substrate of the hard alloy numerical control blade is not damaged within several working days after cleaning. It is oxidized by moisture, thereby improving the bonding strength of the coating and the base of the carbide CNC insert, and prolonging the service life of the carbide CNC coating insert.

Description

technical field [0001] The invention belongs to the technical field of production of hard alloy numerical control coated inserts, and in particular relates to a cleaning method for hard alloy numerical controlled inserts before coating. Background technique [0002] In the machinery manufacturing industry, cutting is one of the most widely used processing technologies. Cemented carbide has the advantages of high strength, high hardness, high elastic modulus, high red hardness, wear resistance and corrosion resistance. One of the commonly used tool materials. The main components of cemented carbide are refractory metals WC and Co. There are many factors affecting the life and performance of cemented carbide CNC tools, including geometric design, matrix composition and surface treatment technology, as well as coating. In terms of composition effects, it mainly focuses on Co content, carbon content in WC, trace elements, grain size and so on. In terms of coating, in addition...
