Realization of mirror finishing of aluminum and Ni-P plating with a general-purpose lathe

[Issue]
We want to achieve mirror finishing of aluminum and Ni-P plating, etc., even with a general-purpose lathe that does not have very high machining accuracy.


[Solution]
Tokyo Diamond Tools Mfg. Co., Ltd. offers mono-crystal diamond cutting tools that can achieve mirror finishing even on general-purpose lathes, thanks to the polishing technology of mono-crystal diamond (MCD) cutting edges that we have developed over many years. The wear resistance of mono-crystal diamond also extends the life of the tool. In addition to aluminum, mirror finishing of gold, copper, brass, etc. is also possible.

    The surface of aluminum machined by a PCD tool is not mirror-like, but rather diffusely reflective and appears white.

    The MCD tool cuts with a very sharp edge, so the machined surface of aluminum appears darker with less diffuse reflection.
