Preferably, the first and second axes of rotation are not coincident with one another and in a more preferred arrangement, the first tool axis and the second tool axis are arranged perpendicularly to one another.

A fixture for facilitating the serial engraving of a plurality of cylindrical objects such as glasses or mugs mounted on individual serially arranged stations along a master base plate. Each station includes a drive structure and, spaced therefrom, a passive support structure. The two structures in each station can be gang-adjusted for object length. In addition, the support structures can be height-adjusted to level the engraved surfaces of tapered objects. All of the drive structures include drive wheel pairs and all are driven by a single stepper motor via a single shaft and individual belt and pulley systems.

A symmetrical tri-axial parallel spindle head capable of multi-directional fixed-point rotation, comprising three branch chains (2), a moving base (5), and a fixed base (1). A machining spindle (6) is fixedly connected onto the moving base (5). Each of the branch chains (2) comprises a servo motor (22), a branch chain rod (21), a lead screw (23), and a guide nut (25). The lead screw (23) and a linear guide rail (24) are provided in an inner cavity on one end of the branch chain rod (21). One end of the lead screw (23) is connected to the servo motor (22), the lead screw (23) passes through the guide nut (25), and the other end of the lead screw (22) is connected to the branch chain rod (21) by means a rotating pair.
