Manufacturing Procedure

The requirement for producing metallic microparts for use in micromachines and/or micromechanisms will continue to increase. This study deals with the manufacturing of tiny parts, of mm-size, using micromachining technology and an ultraprecision milling machine, which consists of a z-motion table, a positionable spindle on it as the c-rotational axis, and an x-motion table. The spindle, which has a pseudo ball end mill composed of a single crystal diamond, is mounted on the x-table. A new manufacturing procedure is devised in order to create a propeller, 3 mm in diameter, as a representative micropart, based on the CAD data of the propeller. As a result, it was found that a functional machined propeller, with a surface roughness of 0.1 μm, can be mounted onto a micromotor shaft, 0.7 mm in diameter.

The Impact

AbstractDeep UV detection using a single crystal diamond (SCD) substrate without a homoepitaxial layer has been demonstrated using a defect passivation treatment. Despite evidence of surface damage on the SCD, the treatments lead to highly effective photoconductive devices, displaying six-orders of discrimination between deep UV and visible light and a responsivity as high as 100A/W, equivalent to an external quantum efficiency of 700, similar to the best values for devices based on high quality homoepitaxial layers. Impedance spectroscopic investigations suggest that the treatment used reduces the impact of less resistive surface material, most likely defects left from substrate polishing.
