A lathe includes a lathe-side chuck that holds a workpiece with the workpiece directed toward or facing a front side, a main spindle that rotates around an axis, and a tool that machines the workpiece. A machining center includes a rotary tool that rotates around an axis in the horizontal direction and an MC-side chuck that holds the workpiece and is able to turn between at least a workpiece pass/receive position in which the workpiece is directed toward or facing the front side and a machining position in which the workpiece is directed toward or facing the rotary tool. A loader includes a guide rail extending above the lathe-side chucks, and MC-side chuck along the horizontal direction and a loader head that holds the workpiece and carries the workpiece between at least the lathe-side chucks, and MC-side chuck by moving along the guide rail.

A rotary indexing machine comprises at least one indexing plate, which is in at least one operating state configured to accommodate and transport at least one work piece, and with at least one clocking cell comprising at least one accommodating unit with at least two opposite-situated accommodating elements, which are configured for together accommodating the at least one work piece from the indexing plate, and comprising at least one machining unit for machining the work piece accommodated by the accommodating unit, wherein the at least one clocking cell comprises at least one bridge unit, which extends at least partially over the indexing plate in an axial direction and is configured to guide the at least two accommodating elements of the accommodating unit in a shared coordinate system.

Disclosed is a wheel cap section chamfering device, comprising a main frame, a secondary frame, a lower servo motor, a key, a bearing seat, a left bearing seat, a left shaft, a left bearing, a left driven friction wheel, a left sleeve, left corner cylinder pressure claws, a left turntable, a left mandrel seat, a left mandrel, a chamfer mill, a tool apron, a feeding platform, a feeding cylinder, guide sleeves, guide posts, a support plate, guide rails, a compression cylinder, a translation sliding table, an upper servo motor, a driving friction wheel, a right mandrel, a right mandrel seat, a right turntable, right corner cylinder pressure claws, a right sleeve, a right driven friction wheel, a right bearing, a right shaft, a right bearing seat, a station rotating platform, a shaft and a bearing.

The present invention is to provide an automatic steel bar coupling head making machine including a positioning mechanism, a transverse moving mechanism, a longitudinal moving mechanism, a processing mechanism assembly and a control mechanism, wherein, when a steel bar is positioned between two fixtures of the positioning mechanism and an end of the steel bar presses against a positioning detection rod of the processing mechanism assembly, the processing mechanism assembly sends a start signal to the control mechanism and, upon receipt of the start signal, the control mechanism drives the positioning mechanism, the transverse moving mechanism, the longitudinal moving mechanism and the processing mechanism assembly, for enabling the two fixtures to clamp the steel bar and then enabling the processing mechanism assembly to sequentially perform a first turning, a second turning and a thread rolling on peripheral edge of the steel bar adjacent to the end of the steel bar.
