Driving systems for tools used with metal-fabricating presses or other machines, whereby planetary gears are used in the systems, and whereby the driving systems can be constructed for use with particular tooling, such as tapping tools, and complementary systems can be exemplarily configured for use with such driving systems. The driving systems can enable enhanced tool output as compared to conventional driving mechanisms, while also enabling variable disassembly and configuration of the systems relative to the intended machining operations.

A processing system for a workpiece, with a thread formation device (44) for forming a thread in a workpiece, comprising a housing and one or more tool take-ups for a thread forming tool, rotatably and displaceably mounted in or on the housing, a linear drive and a rotational drive for the tool take-up(s) and a take-up device with one or more take-ups (19) for integrating the thread formation device (44), is characterised in that the thread formation device (44) can be integrated into the take-up device by means of a disconnectable plug connection.

A device (44) for forming a thread in a workpiece has a housing and a plurality of tool receptacles (2) rotatably and displaceably mounted in or on the housing for a respective thread-forming tool, wherein a linear drive and a rotary drive for the tool receptacles (2) are integrated into the housing.

A multiple tool for a punching device, in particular for a turret punch press has a housing and a tool head interacting with the punching device. A thread cutter magazine including a plurality of thread cutters is connected to the tool head. A selection device is provided to select an active thread cutter which interacts with a workpiece for thread cutting. A thread cutter drive device is provided to drive the active thread cutter. As a result, a multiple tool is obtained which expands the range of applications of a punching device.

A torque-adjustable tapping apparatus includes a tap, a wrench and a torque-adjusting mechanism including a shell, a primary adjuster and a clutch. The shell is connected to the wrench. The shell includes an internally threaded section. The primary adjuster includes an externally threaded section engaged with the internally threaded section. The clutch includes an upper gear and a lower gear. The upper gear includes teeth extending from a lower face and at least one restraining cutout in a periphery. The lower gear includes teeth extending from an upper face and a connective rod extending from a lower face. The teeth of the lower gear are engaged with the teeth of the upper gear. The connective rod is connected to the tap. At least one screw is inserted in the restraining cutout through the screw hole. A spring is compressed between the primary adjuster and the upper gear.

A drilling tool for a punch device, in particular for a turret punch device, comprises a housing, a tool shank arranged in the housing with a drilling means accommodated therein and a tool head arranged on the tool shaft to interact with the punch device. The tool head of the drilling tool has a ram engagement portion configured to transmit a rotational movement about a tool longitudinal axis from an external drive to the tool head.
