A method for producing a high strength tube part is provided. The method includes the acts of: producing a sheet metal blank, producing a tube part by cold forming the sheet metal blank, and hardening the tube part at least in some sections to a high strength tube part.

A portable pipe threader includes a stand upon which a pipe is supported, a carriage supported by the stand upon which at least one pipe threading tool is supported, a spindle including a plurality of chuck jaws for clamping the pipe, the chuck jaws configured to move radially inward along a travel path toward an outer surface of the pipe, and a sensor system configured to determine a location of the chuck jaws along the travel path and relative to the outer surface of the pipe, the sensor system configured to output a signal corresponding to the location of each of the chuck jaws when engaged with the outer surface of the pipe. The portable pipe threader further includes an electronic controller in communication with the sensor system configured to determine an outer diameter of the pipe in response to the signal output from the sensor system.

The whirling device comprises a retaining ring extending around a ring axis and a central opening and having at least one receiving area for a machining element for machining rod-shaped material in the area of the central opening. A coolant supply comprises a supply sleeve which is arranged on the retaining ring via a rotary bearing and comprises a coolant connection and a supply area adjoining a connection area of the retaining ring. Starting from at least one inlet opening in the connection area of the retaining ring, at least one passage leads through the retaining ring to at least one outlet opening which faces the central opening of the retaining ring and is designed for a machining element in a receiving area. No space is required for the coolant supply between the retaining ring and an assigned lathe.
