Study of spindle drives for boring machines

Abstract

This paper examines the main requirements for the electric drive systems of a class of boring machines with digital program control. On this basis, a methodology for choice of the spindle drives is offered. The algorithm takes into account the specific features of the technological processes, the treated materials, the tools used and their wear, as well as the mechanical gear types. The experimental studies of the implemented electric drives for the spindle are presented and discussed. The research carried out and the results obtained can be used in the development of such drives for the studied class of machine tools.

Study and Performance Improvement of the Drive Systems for a Class of Machine Tools

“…The spindle drive should meet the following requirements [10]: dual-zone speed control (by constant torque and constant power); high maximum speed; oriented braking; reversible speed regulation.…”

“…The tabular data are taken from companies producing tools, mechanical gears and guides [11][12][13]. Methodologies for selection of spindle drives, linear and rotary feed drives for different mechanical operations are presented in [8][9][10], [14,15]. The catalogue data are obtained from the some manufactures of motors, power converters, sensors and mechanical gears [16][17][18][19][20].…”

Performance Improvement of a Type of Turning Machines

“…A methodology for selection of spindle drives for turning machines is presented in [17]. On the basis of this methodology, DC and AC electric drives are chosen.…”
