Diamond tools have the advantages of extremely high hardness and wear resistance, low friction coefficient, high elastic modulus, high thermal conductivity, low thermal expansion coefficient, and low affinity with non-ferrous metals.
We need to understand a little knowledge
1. The life of diamond-coated tools varies
Like any other tool, the life of diamond-coated tools is also different. It depends mainly on the material being cut, the selected feed rate and cutting speed, and the geometry of the workpiece. Generally speaking, the life of diamond-coated tools for processing graphite is 10-20 times longer than that of uncoated carbide tools, and in some cases it can even be longer.Laser Welded Diamond Saw Blade
2. Problems with diamond tools
The peeling off of the diamond coating can prevent the peeling off of the coating. It is a serious problem of diamond-coated tools, and it is also a common problem (especially when processing carbon fiber and other materials), which will cause the tool life to be unpredictable. In the late 1990s, interface chemistry was determined to be an important factor affecting the adhesion performance of diamond coatings.
3, the difference between CVD diamond coating and amorphous diamond coating
Amorphous diamond (also known as diamond-like carbon-Annotation) coating is a carbon film deposited by the PVD process. It has both part of the SP3 bond of diamond and part of the SP2 bond of carbon; its film formation hardness is very high, but it is lower than the hardness of diamond film; its thickness is also thinner than the diamond film we usually deposit. When processing graphite, the life of amorphous diamond-coated tools is 2-3 times longer than that of uncoated carbide tools.Supplier Diamond Circular wet Saw Blade
Diamond tools have the advantages of extremely high hardness and wear resistance, low friction coefficient, high elastic modulus, high thermal conductivity, low thermal expansion coefficient, and low affinity with non-ferrous metals. Before selecting and using diamond-coated tools, users need to understand the following common sense about diamond-coated tools:
