About machinable aluminum nitride sheets machinable aluminum nitride is a sintered aluminum nitride boron nitride ceramic composite with high thermal conductivity and mechanical strength low thermal expansion and the ability to be machined into complex shapes via carbide cutting tools.
Cutting aluminum nitride sheet.
We cut 0 7 mm thick aluminum nitride sheet with a carbon dioxide laser using a large matrix of process variables and examined the resulting edges for surface quality microcracking aluminum deposition and recast.
With this information we defined the volume in process space where effective processing can be accomplished.
Zrn or dlc is ideal.
However the sintering process that is required to fully densify the material causes the aluminum nitride body to shrink approximately 20.
Aluminum nitride can be machined in green biscuit or fully dense states.
Calico tialn is normally applied to steels hardened steels and stainless steel materials where high wear resistance and lubricity are needed.

Calico aluminum titanium nitride altin is a hard coating that solves many tribological problems with components that can be coated at temperatures of 450 c 475 c.
Silicut is a nanostructured coating made by incorporating titanium and aluminium nitrides nanocrystals in a silicon nitride matrix.
Calico aluminum titanium nitride tialn is a hard coating that solves many tribological problems with components that can be coated at temperatures of 450 c 475 c.
Any coating or no coating is better.
It s important not to use titanium aluminum nitride altin or tialn coatings when cutting aluminium as the aluminium in those coatings chemically reacts with the workpiece and causes a built up edge.
Calico altin is normally applied to steels hardened steels and stainless steel materials where high wear resistance and lubricity are needed.
The matrix forms a very thin film around altin nanocrystals works as a strong interface and provides the layer with the typical structure of composite materials.
The carbide teeth on these steel saws cut aluminum brass bronze steel and plastic sheets and last up to twice as long as high speed steel teeth.
Aluminum nitride machining grinding.
Although the titanium aluminum nitride tialn coatings may not be as hard as ticn at room temperature it proves to be much more effective in applications where heat is generated.
This coating holds its hardness at higher temperatures due to a layer of aluminum oxide that forms between the tool and the cutting chip.
