Facility Features, Working Principle and Specifications
Nanoform X ultra grind is the small-frame ultra-precision machine equipped with pneumatic vibration isolation and a fully flood coolant system. The key features of the facility are the use of air-bearing spindles, pneumatic slides, and a feedback control system that helps in achieving precision movement and accuracy. The machine is designed for diamond turning, which is used to fabricate different components with precision-finished surface quality, having surface roughness in the nanometric level and form accuracy in the sub-micron range. Silicon and other difficult-to-machine materials can be manufactured efficiently with high surface quality using this facility.
Diamond turning machine (DTM) uses a sharp-tipped diamond tool, either natural or synthetic, to manufacture precision components with very high surface quality. The process is capable of producing ultra-smooth surfaces that do not require additional polishing. In DTM, the workpiece is mounted on a spindle with rotational motion, and the diamond tool is attached to the tool holder subjected to linear motion. The material removal from the workpiece takes place owing to relative motion between the diamond tool and the workpiece. Surface quality of the work sample is dependent on the tool specification, machining parameters, and material properties.
