Art tools commonly used in paper cutting and packaging industries, with the development of technology art tools are also constantly developing, in material selection and production processes have been greatly improved. Tool types produced by art tool manufacturers are also very diverse, so we have to consider a number of factors when selecting them.
In the choice of tool point of view, you need to consider the impact of many factors, such as workpiece materials, tool materials, processing properties. Generally speaking, the angle of the cutter refers to the angle of marking for manufacturing and measurement. In practical work, the actual working angle differs from the marking angle due to the different installation positions of cutting tools and cutting movement direction, but the difference is usually small .
The material used to make the tool must have high high temperature hardness and wear resistance, the necessary flexural strength, impact toughness and chemical inertness, good processability. Usually when the material hardness is high, wear resistance is also high; high bending strength, high impact toughness. Due to its high flexural strength and impact toughness and good machinability, HSS is still the most widely used tool material, followed by cemented carbide.
Carbide indexable inserts are now coated with titanium carbide, titanium nitride, aluminum oxide hard layers or composite hard layers by chemical vapor deposition. Hard coatings act as barriers to chemical diffusion and heat conduction, slowing the tool wear during cutting and increasing the life of coated inserts by about 1 to 3 times longer than uncoated ones.
