A method for producing one or more bearing components along a production line, comprising honing the bearing components along the production line, cleaning the bearing components along the production line, grinding the bearing components along the production line, and transporting the bearing components along the production line utilizing one or more transport units.

A device and a method for machining, especially for polishing of an optical lens, are proposed, there being both a lens changing apparatus and also a separate tool changing apparatus. The lens changing apparatus is located between a working space and a conveyor apparatus for lenses and is pivotally mounted around a horizontal axis. The tool changing apparatus is located laterally next to the working space.

The invention discloses a special disinfection cabinet for wooden cutting boards. The disinfection cabinet includes a disinfection cabinet. The disinfection cabinet is provided with a disinfection cavity which is opened forward. The disinfection cavity is provided with a support plate. The cutting board is placed on the left end face of the support plate, the cutting board is clamped by the clamping mechanism, and a pushing mechanism is provided on the right side of the support plate. Before disinfecting the cutting board, the invention first polishes the surface of the cutting board Grind off the surface of the cutting board, so that most mold can be removed, and the knife marks on the surface of the polished cutting board can also be removed to prevent bacteria from accumulating and breeding. Then rinse the cutting board and use ultraviolet radiation to Compared with the traditional disinfection method, the disinfection effect is better.

The invention relates to an electric hand-held tool with a tool mount, a motor for driving a tool fastened in the tool mount, and a housing which includes a handle area, a motor area for accommodating the motor, and in which vent openings are configured for the ventilation of the motor. At least in the area of the vent openings, the housing is provided with at least one cover with a closed surface, said cover sitting flush against the housing with an edge area facing the tool mount, being arranged at a distance from the housing in an area above the vent openings, and leaving a gap between the cover and the housing in the area of its edge area facing away from the tool mount.

The present invention relates to an actively dampened centerless grinding process for a centerless grinding machine having wheels, between which there is arranged a part to be ground, and heads carrying the wheels, which process has moving the wheels closer to one another by applying pressure on the part for the grinding thereof, such that vibrations are generated in the grinding machine due to grinding, measuring the vibrations due to grinding, and introducing, depending on the measurement, an active damping force (F.sub.act) parallel to the force flow of the grinding machine and by means of using an inertial actuator acting directly on one of the heads, such that the vibrations due to grinding are attenuated.

A system for replacing an abrasive sheet in a sanding machine including a working head in which it is provided a support body having an engagement surface arranged to engage with an abrasive sheet. The sanding machine also includes a handling device arranged to actuate the support body in space according to at least two degrees of freedom. The system may include a computing device to compute the spatial orientation of the support body. Furthermore, the system may include a removal station having a gripping element configured to grip the abrasive sheet in order to disengage the abrasive sheet from the support body.

A machined wheel post-processing equipment includes a wheel inlet roller way, a lower machine frame, lower guide posts, lower air cylinders, a supporting plate, guide sleeves, a lifting table, guide rails, a clamping cylinder, a left sliding plate, a right sliding plate, a rack and pinion, servomotors, a lifting roller way, clamping wheels, a first servomotor, and a overturning platform.

A power tool includes a housing, a motor, an output shaft, a working head, a transmission assembly, an auxiliary handle, and a vibration damping assembly. The auxiliary handle includes a front end mounted at a position of the housing adjacent to the working head, and further includes a gripping portion extending along a center line. The vibration damping assembly includes a mass member and an elastic element. The auxiliary handle further includes an end cap arranged at a rear end of the gripping portion where the rear end is far away from the housing relative to a front end of the gripping portion. An accommodating cavity for accommodating the vibration damping assembly is formed around the gripping portion when the end cap is combined with the gripping portion. The elastic element is arranged between the mass member and a cavity wall of the accommodating cavity, and a ratio of a natural frequency W1 of the vibration damping assembly to a rotation frequency W2 of the output shaft in rotation is greater than or equal to 0.7 and less than or equal to 1.3.

A grinding apparatus includes a holding table for holding a wafer, a support table for supporting the holding table, a motor for rotating the support table, a frame member supporting the support table for rotation, and at least three support poles for supporting the frame member from the base. Each of the support poles has formed in the inside thereof a through-hole, a supply port which communicates the through-hole and an air supply source with each other, and an exhaust port which exhausts air having flowed through the through-hole toward the support table. Air is supplied into the through-hole to cool the support pole, and the air having flowed through the through-hole is exhausted toward the support table.
