Technical University of Denmark - DTU Nano Machining using 0.0002\' size end mills.

Microscope image of micro milling tools with diameters of 25Ám and 200Ám, respectively.

  Nano Machining is achieved at the Department of Micro and Nanotechnology at the Technical University of Denmark using a Minitech CNC Micro Milling Machine.

Frederik Bundgaard is shown with a Minitech Mini-Mill/3Pro equipped with a 50K RPM precision spindle. End mills range from .0004\' to 0.0002\' and show no deviation in repeatability when machining.

The stepper motors controlling the stage employ micro-stepping, and a XYZ resolution of around 1Ám is achieved. The repeatability of the system, including the spindle run-out, has been experimentally found to be less than 5Ám when working on areas a few centimeters across, which is the dimension typically used for Microfluidic Systems.

These photos are close-ups of a Microfluidic channel milled in Topas grade 5013.

Picture A. Channel milled using a 200Ám tool. The side channel is milled using a 25Ám tool. The half circle pattern on the channel bottom stemming from the end mill is clearly seen.

Picture B. A 100Ám wide and deep channel and through-hole 500Ám in diameter. The surface of the channel bottom is slightly more rough than the sidewalls. The sides of the hole appear more rough than the channel.
