Carrousel Diamond Turning Lathe
TU/e Equipment & Prototype Center (formerly GTD). PhD subject of Dr H. Vermeulen, MSc.
Diamond turning lathe for the high-precision machining of work pieces. Both the main spindle and guideways have aerostatic bearings. The guideways are driven by Anorad linear motors. The displacement is measured and fed back by Heidenhain zerodur rulers with a resolution of 5 nm. The main spindle is driven by a brushless servomotor. For the control a PMAC digital controller is used.
- Work piece size max. diameter 300 mm, height 300 mm
- Size variation max. 0.1 µm
- Ra 10 nm
