Study on the Influence of Spindle Running Accuracy and Feed Drive Characteristics of a Diamond Turning Machine on Work Piece Accuracy
Subscribe/Renew Journal
Surface roughness of the order of few nanometers and form accuracies of the order of few hundred nanometers are the requirements of the components produced on a Diamond Turning Machine. Spindle running accuracies and feed drive characteristics of the machine are the significant factors, which are likely to limit the work piece accuracies that can be achieved on the machine.
The paper presents the studies conducted on the diamond turning machine, developed at CMTI using high precision integrated motor aerostatic spindle and hydrostatic slide driven by high precision friction drive, to establish the influence of the spindle error motions and feed drive errors of the linear axis on the work piece accuracy. The results show the correlation of various spindle errors and feed drive errors of the linear axis with the work piece errors.
