What cutting fluid can be used to process oxidized aluminum parts for CNC production?
The material in the aluminum alloy and the cutting fluid cause an oxidation reaction; the plasticity of the aluminum alloy is low, the melting point is also low, and the thermal conductivity is good. If the lubricity and cooling of the cutting fluid are not reached when processing the aluminum alloy, it will cause the aluminum alloy processing to appear. Tool sticking and chip removal performance is poor. In such a cycle, the tool is corroded and the probability of tool breakage is greatly improved. Secondly, when processing aluminum, it depends on the compo

What to pay attention to when machining titanium alloy by cnc
The machinability of titanium alloy is: low density, poor thermal conductivity, and cutting heat is not easy to diffuse during cutting, resulting in a short tool life. Titanium alloy has high affinity; it has high chemical activity and is easy to interact with the metal in contact, resulting in increased adhesion, diffusion, and tool wear; titanium alloy has low elastic modulus and large elastic deformation, which will make the processed surface and the back knife The contact area of the surface is large, and the wear is serious. Due to the small modulus of elasticity of titanium alloy,
