A device for removing flashes of a wheel blank includes two layers of turnover mechanisms, wherein the lower-layer turnover mechanism realizes the initial positioning of a wheel and has the function of removing the flashes at both the inner side and the outer side of an inner rim of the wheel, and the upper-layer turnover mechanism realizes the secondary positioning of the wheel and has the function of removing the flashes on the outer rim side. By means of the two layers of turnover mechanisms, the flashes on the front face and end face of a wheel blank outer rim wheel lip, and the inner side and outer side of the inner rim are removed, and coaxial processing conversion and orderly takt connection are ensured. The disclosure also provides a method for removing flashes of a wheel blank.

Various components of an electronic device housing and methods for their assembly are disclosed. The housing can be formed by assembling and connecting two or more different sections together. The sections of the housing may be coupled together using one or more coupling members. The coupling members may be formed using a two-shot molding process in which the first shot forms a structural portion of the coupling members, and the second shot forms cosmetic portions of the coupling members.

A tool for material-removing machining of a workpiece has a proximal and a distal end, a shaft for connecting the tool to a drive in the region of the proximal end, and a tool head in the region of the distal end. Cutting elements on the tool head are configured such that they are capable of being introduced into the workpiece to be machined and they are capable of removing a material layer from the workpiece. The cutting elements also include at least one cutting tooth having a cutting tooth ridge and a cutting tooth root, and at least one cutting jaw having a cutting jaw ridge and a cutting jaw root. The ratio between the cutting tooth ridge and the cutting tooth root is smaller, in particular between two and ten times smaller, than the ratio between the cutting jaw ridge and the cutting jaw root.

A portable rail weld milling machine apparatus comprises a support structure comprising a milling tool, wherein the milling tool comprises a milling head for milling a railroad rail by moving the milling tool in a first direction longitudinal to parallel railroad rails, in a second direction lateral to the parallel railroad rails, and a third direction vertically.

A deburring tool (7) for deburring of edges of transverse recesses (3, 3a-i), which diverge from a main borehole (2), consisting of a shaft (8, 9) driven to turn about the tool axis (11), which is deployable and retractable in the forward feed direction into the main borehole, and on the lower end of which at least one knife window (26) is arranged, in which at least one spring-loaded knife (10, 10′, 10″, 10′″, 10″″) is arranged roughly perpendicular to the tool axis (11), so as to be shiftable, which on its front end has at least one cutting edge (10a, 10b) which encounters the edge of the transverse recess (3, 3a-i), and deburrs same, wherein the knife (10, 10′, 10″, 10′″, 10″″) consists of two cutting edges (10a, 10b) opposite in the rotational direction (12, 13), which act to cut equally for the right and left passes (12, 13), with one cutting edge (10a) being configured to cut for the rightward pass (12), both in forward motion (38a) and in rearward motion, and the other cutting edge (10b), being configured to cut for the leftward pass (13), both in forward motion (38a) and in rearward motion, and that the two cutters (10a, 10b) with their cutting edges are placed at a slant and with arch shape at an angle between 0° and 90°, but preferably between 5° and 45° to the tool axis (11) and thus to the longitudinal axis (2a) of the main borehole (2).

A deburring tool includes: a case; a hollow sleeve that reciprocates inside the cylinder in a non-rotating manner; a drive gear disposed inside the sleeve, includes a first tooth, and rotates together with the case and the sleeve; a reciprocating shaft disposed inside the sleeve, including a driven gear disposed at a basal end portion of the sleeve and a basal end side of the drive gear, the driven gear including a second tooth, a tool holder disposed at a distal end portion of the sleeve, and slides inside the sleeve in a rotational and reciprocating direction, and a stem that fixes the driven gear and the tool holder, and penetrates the drive gear, a first spring that urges the sleeve toward distal end direction; and a second spring that urges the tool holder from the drive gear toward distal end direction.

A portable rail weld milling machine apparatus comprises a metal frame that incorporates a motor with a rotary carbide tool that is able to lock to a rail or rails for stability. The apparatus houses the required guides and motors to maneuver the tool on a plurality of axes with computer numerical control (CNC). The CNC programming is able to control the carbide tool such that the welded rail can be milled to proper profile on the entire running surface, including the top, the field side, and the gauge side of the ball of the rail.

A milling tool for producing chamfer surfaces at workpieces. It has a cylindrical shaft and a cutting part, which has at least two end cutting edges, which are each located on a cone jacket surface and which run in a spiraled convex manner in the direction of rotation, and which each extend from a radially outer cutting corner to an inner cutting corner on the end side. To broaden the area of application of the milling tool to processes, such as the ramping or the linear diagonal plunging, respectively, the circular milling, the spot-drilling, or the waterline milling, the end cutting edges merge at the inner cutting corner into center cutting edges, which are located on a cone jacket surface with a tip angle of above 180, and which run with a positive chip angle into a region of the milling cutter center located in the milling cutter core.

A tool for removing burrs/flash from a work piece includes a linear body having a cutter/abrasive end and an opposite shank end. The shank end is adapted for attachment to a rotary power source. At least one bushing is secured to the linear body, the bushing allowing rotation of the tool there within while an outer portion of the bushing remains stationary.
