The Minitech 4 axis CNC micro milling machine can be used for fast prototyping of molds, devices or sample holders. It can be used with polymers or soft metals, to micro-machine complex shapes or precisely drill holes with micro bits. Designs can be implemented using Solidworks and Mastercam software. The stepper motors controlling the stage employ micro-stepping, and a XYZ resolution of 1 μm is achieved. The repeatability of the system, including the spindle run-out, has been experimentally found to be less than 5 μm when working on areas a few centimeters across, which is the dimension typically used for microfluidic systems.
