Tool for submicron groove
Tool for submicron groove
(OP)
Hi,
I have 0.5um thick layer of a soft polymer on the OD of a polished titanium drum and am looking for a tool to put a 0.5um wide V-groove through the polymer to the titanium base. Only the bottom 0.5um of the tool/blade will be used. There will be very little pressure on the tool. It will ride up and down on the drum OD. The drum will rotate beneath the tool. Does anyone know where I can source a blade/tool that might work for this application?
Thanks,
Ken

Have you even got a way to measure the edge radius?
I've heard rumors that some surgeons prefer knives made from chipped/fractured obsidian, but I've never seen a modern one, and I'm not convinced that producing an edge as sharp as you want is possible even in that material.

Thanks for responding. We make a relief of the groove and visualize it under SEM. I'm going to try obsidian, but am afraid that its brittle and will probably chip against the titanium base as we rotate the drum. I am hoping to find a less brittle blade material, like a metal, that can be sharpened to a ~250 nm tip radius.

Not sure of the edge thickness, but certainly cheap and easy to replace.

"Therefore, a blade geometry with a 200 um (0.2 mm) radius on the cutting edge of the blade could be easily molded today in Liquidmetal alloy, followed by a simple grind, etch, or other technique to finish the edge to the customer’s specification."
It is better to have enough ideas for some of them to be wrong, than to be always right by having no ideas at all.
