A method of removing flash from a gauge portion of a monolithic precursor test coupon using a flash-removal tool is provided. The flash-removal tool comprises a tool body, extending along a longitudinal tool axis, a tooth, and an engagement surface, spaced apart from the tooth along the longitudinal tool axis. The tooth projects from the tool body in a first direction and comprises a shearing surface, facing in the first direction and located an offset distance away from the longitudinal tool axis in a second direction. The method comprises steps of coupling the engagement surface of the flash-removal tool against a first precursor-coupon end of the monolithic precursor test coupon, orienting the longitudinal tool axis parallel to a longitudinal symmetry axis of the monolithic precursor test coupon, wherein the shearing surface registers longitudinally with the flash, and shearing, using the shearing surface, the flash from the gauge portion.

Drawing device for drawing a tool (T), comprising: a support (2), provided with rests (21), structured to be slidably arranged in contact with an inner wall of a tube, and an attachment (22) for a tool (T); a cursor (3), movable along a longitudinal direction (Y) between at least a starting position and a return position; magnetic means (4), predisposed to magnetically constrain the support (2) and the cursor (3) with respect to the displacement along the longitudinal direction (Y).

A method for manufacturing a vehicle wheel of the present invention includes a step of performing an edge treatment including deburring of a spoke edge generated by lathe processing. For the edge treatment, a cutting tool as hale type tool for non-rotational processing is used, and the cutting tool is provided with a processing blade having a recessed blade edge having an R shape or polygonal C shape protruding from an outer peripheral surface on a side of a tip end of the rod-shaped cutting tool connected to a rod-shaped shank portion. A processing machine capable of CNC of four or more axes is used. With the cutting tool standing upright against a disc surface, the blade edge of the processing blade is applied to the spoke edge, and the cutting tool is continuously moved relative to the spoke edge along a ridgeline of the spoke edge for scraping.

Positions of both end edges of a weld bead in a bead width direction are measured over the entire circumference of a liner in a circumferential direction of the liner. Based on information on the position of the end edge, bead profile information being information on a shape of the end edge of the weld bead over the entire circumference of the liner in the circumferential direction is created. Based on this bead profile information, machining information of the liner per rotation of the liner being position information of a cutting tool in the bead width direction per phase in the circumferential direction of the liner is created so that a moving locus of the cutting tool relative to the liner along the circumferential direction of the liner approximates the shape of the end edge of the weld bead over the entire circumference of the liner in the circumferential direction.

A device (100) for covering the welding area for hot rolling lines consists of an outer container (1), a protective shield (2), a blade-holder (3) with scraping blades, and an actuator (9). Protection occurs by linearly sliding the protective shield (2) outside the outer container (1) up to minimizing the gaps with the billets. The cleaning occurs at the same time as the return to the rest position: the scraping blades, which are integral with the container (1) and are installed in contact with the inner surface of the protective shield (2), slide thereon during the raising, thus colliding with the deposits of solidified material and removing them. Completing the device (100) additionally is a small alternating linear motion of the protective shield (2) during operation to always keep the attachment area of the scraping blades clean, thus avoiding the need for excessive detachment forces at the beginning of the raising.
