摘要

The known multi-spindle automatic lathes are expensive on account of the complicated construction, and the production capacity and the production possibilities are restricted on account of the limited number of workpiece spindles used. The novel automatic lathe is to offer higher production capacities and universal production possibilities in a simpler construction. …The basic construction of an automatic lathe with eight tool spindles (10) for producing workpieces in eight successive machining stations consists in the fact that, in addition to the number of basic tool stations (1 to 8), each basic tool station, except for the first, is again provided as an additional tool station (2 to 8). The additional tool stations (2 to 8) are arranged in front of the basic tool stations (1 to 8) in the same machining sequence so that the total number of machining stations N = 2n - 1, a loading and unloading station being provided at the tool station (1). The workpieces are machined in such a way that, after each machining operation in a tool station, each workpiece is displaced linearly in cycles relative to the next station and passes into its initial machining station after seven transfer steps and a subsequent return stroke or a return stroke between two transfer steps. …The multi-spindle automatic lathe can be used for the mass production of workpieces of the most varied type. ……
