Disclosed is a machining unit for machining a bearing component. The machining unit includes an industrial robot and at least one abrasive tool. The at least one abrasive tool is coupled to the industrial robot and a controller. The controller is configured to control a movement path of the at least one abrasive tool such that a contact of the abrasive tool is in the normal direction to a surface of the component.

The present invention relates to a pressure shoe (1) for pressing finish band onto surfaces of a rotating workpiece, with a carrier (2), a radial press-on surface (3) for pressing finish band onto a circumferential surface of the workpiece, and axial press-on surfaces (4) for pressing the finish band onto axially aligned cheek surfaces of the workpiece that border the circumferential surface, wherein
at least one axial press-on surface (4) is formed by at least one axial press-on element (5), and the at least one axial press-on element (5) can be at least sectionally moved at least in an axial direction (9) relative to the carrier (2).

A crankshaft with improved seizure resistance is provided. A crankshaft includes a journal and a pin, each of the journal and pin having such a surface geometry that the arithmetical mean height of the primary profile, Pa, is 0.090 μm or smaller and the reduced peak height Rpk is 0.070 μm or smaller. As used herein, arithmetical mean height of a primary profile Pa is defined in JIS B 0601 (2001), and reduced peak height Rpk is defined in JIS B 0671 (2002).

A microfinishing machine and method especially adapted for processing of internal combustion engine crankshafts and other workpieces. Microfinishing is achieved by tooling having abrasive inserts or which present abrasive coated film against the journal to be machined. The tooling has a width less than one-half the length of the journal being machined. The narrow width tooling allows a range of workpiece configurations to be processed with common tooling, and through control of one or more of machining parameters including clamping pressure acting on the tooling, oscillation of the tooling, and stroking schedule of the tooling, desired journal contour profiles can be produced.

A continuous abrasive product includes predetermined length and number of predetermined kind of abrasive areas on an abrasive surface, A method for abrading a workpiece, includes arranging an abrasive area of an abrasive product at an abrading zone for abrading the workpiece, and after abrading, replacing the abrasive area at the abrading zone with an another abrasive area of the abrasive product for abrading the workpiece according to a subsequent abrading phase. The used abrasive area is replaced by an unused abrasive area of a different kind. The abrasive product comprises a continuous longitudinal abrasive material including at least two longitudinally sequential different abrasive areas having different kind of abrasive properties.

An automatic processing device of a carbon fiber tube includes a polishing device, a washing device, a first drying device, a printing device, a painting device and a second drying device centrally disposed along an identical axis in sequence to form an automatic production line. The polishing device includes feeding mechanisms disposed on two sides of a frame respectively and a positioning-polishing mechanism disposed between the feeding mechanisms. The printing device includes a supporting mechanism and a rolling-printing mechanism mounted on the frame. The disclosure aims at providing an automatic processing device of a carbon fiber tube and a processing method thereof, combining the polishing device, the printing device and the painting device as a whole. Separate processes such as polishing, printing and painting of the conventional carbon fiber tube are integrated to achieve the automatic production in the production line, which can significantly speed up the schedule.
