A method is used to manufacture a surgical instrument including a first tube, and a second tube. The first tube extends from a proximal first end portion to a distal first end portion. The second tube extends from a proximal second end portion to a distal second end portion. The second tube is positioned coaxially within the first tube with the distal second end portion positioned adjacent to the distal first end portion. The second tube defines a lumen. The sensor is secured proximal to the distal second end portion of the second tube. A die is engaged against a distal first end portion of the first tube while first tube rotates about its own longitudinal axis; and the die is simultaneously moved relative to the distal first end portion of the first tube along a predetermined path to form a predetermined shape.

A cylindrical-battery beading device according to the present disclosure may include: a device body capable of moving forward or backward; a beading tool unit including a beading knife and a knife support block to which the beading knife is coupled, and coupled to the device body so as to reciprocate relative to the device body; and a beading-pressure measurement unit fixed to the device body and configured to come into contact with the knife support block and measure a force by which the knife support block is pushed backward during a beading process.

The invention relates to a flow-forming machine and a method for flow-forming a substantially rotation-symmetric workpiece having a drum-shaped circumferential portion, comprising a spindle which can be driven in rotation about a spindle axis, a clamping device which is arranged on the spindle and has a plurality of clamping elements which are adjustable between a clamping position, in which the clamping elements abut against an outer circumferential region of the workpiece with a predetermined clamping force and hold the workpiece on the spindle for forming, and a release position in which the clamping elements are spaced from the workpiece in a defined manner for releasing the workpiece from the spindle, by means of a first actuating device, wherein the clamping force for holding the workpiece on the spindle during forming can be applied by the first actuating device, and a plurality of forming rollers which are radially and axially feedable to the drum-shaped circumferential portion for forming the circumferential portion of the workpiece. According to the invention, it is provided that a second actuating device is provided on the clamping device, by means of which a position of the clamping elements can be set in a radial direction for adapting to a diameter of the workpiece, and that a control device is provided, by means of which the second actuating device can be actuated depending on the diameter of the workpiece to be formed, wherein the clamping elements are radially pre-positioned depending on the diameter of the workpiece.
