3 Terms and Definitions
The following terms and definitions apply to this standard.
3.1
Hard coating hardcoating
The tool surface is coated with a hardness greater than 1800HV film layer to improve the wear resistance of the tool coating.
4 Coating free expression and common coating element
4.1 high-speed steel cutting tools coating is applied by physical vapor deposition (PVD) production method, it can generally be divided titanium-based, titanium-based aluminum and aluminum chrome base three. often
Coating elements of expression in Table 1.
4.2 high-speed steel cutting tools should be based tool varieties, the workpiece and the cutting parameters required to select suitable coating.
5 before coating tool (base) of the technical requirements
5.1 Appearance
5.1.1 before coating the tool should be without any surface treatment, and non-magnetic and rust.
5.1.2 require coating part of the work should not have chipping, burrs, cracks and grinding burn and other defects affecting performance.
5.1.3 Tool no screws or pressure fixing portion.
5.2 surface roughness
The upper limit of the work required surface roughness of the coating is Ra0.8μm.
5.3 dimensions and tolerances
Tool required dimensions and tolerances and geometric tolerances should be considered part of the coating thickness.
5.4 Hardness
Before coating hardness of the tool shall comply with relevant product standards.
6 After the technical requirements of coated tools
6.1 Appearance
6.1.1 coated tools working part should not have to chipping, cracking, magnetic, rust and arc spots and other defects affecting performance.
6.1.2 coat color should be consistent.
