Embodiment Construction
[0010] The present invention will be further described below in conjunction with the accompanying drawings of the description.
[0011] The cutting tool feeding method for bearing ring turning of the present invention is to divide the complete tool feeding stroke into at least two sections of strokes, and perform a tool retraction after each section of stroke to break off chips. Specifically, the digital controller is used to control the servo motor to drive the carriage to realize the feeding and retracting of the tool. As an example, the complete feed stroke is divided into two strokes, the first feed stroke and the second feed stroke are respectively 60-80% and 40-20% of the complete feed stroke.
[0012] At present, hydraulic lathes are selected for turning bearing rings because hydraulic lathes have good rigidity and high turning force. However, since the hydraulic lathe adopts the feed control mode of hydraulic actuators, it is difficult to realize multiple movements of...
