Heat generated during braking is reduced to prevent reduction in braking performance or the service life of the components. A grinder includes a housing, an operable member, a switch operable to be turned on or off in response to an operation on the operable member, a rotational shaft rotatable in response to an operation for turning on the switch, and a brake assembly that applies braking to the rotational shaft with the switch being in an off state and to release the braking applied to the rotational shaft in response to an operation for turning on the switch performed by the operable member. The brake assembly includes a brake member being circular and fixed to the rotational shaft, and multiple pressing members that press the brake member at multiple positions to apply a uniform force to the brake member from radially outward positions toward a center of the brake member.

A power tool includes a motor housing, a motor, a handle coupled to the housing, and a vibration damping assembly. The motor is positioned in the motor housing and configured to rotatably drive an output shaft. The vibration damping assembly is positioned between the motor housing and the handle. The vibration damping assembly includes a first coupling portion defined by the motor housing, a second coupling portion defined by the handle, and an elastomeric damper captured between the first coupling portion and the second coupling portion. The first coupling portion includes a boss having a flange and a first groove. The second coupling portion defines an opening and includes first and second ribs extending into the opening and spaced apart along a longitudinal axis of the handle. The first and second ribs define a second groove therebetween. The damper occupies the first and second grooves.

The invention relates to a device (10) and a method for processing brake pads (44) fitted on pad holders (46), comprising a conveying device (16) for continuous and automatic movement of brake pads (44) to be processed and at least one processing station (12). The conveying device (16) of a device according to the invention (10) comprises several bearing faces, which are driven in a revolving manner by the conveying device (16), for the arrangement of pad holders (46) of the brake pads (44) to be processed and positioning means revolving with the bearing faces, said positioning means counteracting a rotation of the pad holders (46).

A machine for working glass slabs includes a supporting structure, a slab grinding section having grinding heads, a conveyor assembly adapted to move the glass slab, and a slab drilling section having a conveyor adjacent to the conveyor assembly. The slab grinding section has suckers for keeping the glass slab next to a working plane spaced and/or offset with respect to the advancement plane, and a computerized numeric control assembly to perform workings on the glass slab.

The invention relates to a grinding machine, which is suitable for a robot-supported grinding process. According to one embodiment, the grinding machine has a housing, a motor arranged in the interior of the housing, a fan wheel arranged on a motor shaft of the motor in the interior of the housing, and a support plate coupled to the motor shaft for receiving a grinding disc. The support plate has openings for intake of grinding dust into the interior of the housing. The grinding machine furthermore has an outlet arranged in a wall of the housing for exhausting the grinding dust out of the interior of the housing and a non-rerun valve arranged in the wall of the housing. The non-return valve enables an to escape from the interior of the housing, but prevents intake of air into the interior of the housing.

A tool for chamfering cleaved tips of optical fibers. The tool including conical bores of relatively smooth and hard material terminate at a cylindrical bore that is slightly larger than the fiber core maximum diameter and a fiber centering bore that is slightly larger than the fiber coating maximum diameter. The tool provided such that when a cleaved fiber tip is inserted into the centering bore the sharp edge falls upon the chamfering surface that, when rotated relative to the fiber, gently grinds the edge to the chamfer angle. Chamfering cannot occur on the core face due to the absence of tool surface at this dimension.

A grinder tool with blind mounting of a disc includes a center alignment mechanism having a first contact and a second contact and a rotational device including an axle that is movable with respect to the center alignment mechanism. A hub is mounted to the axle including a first coupling interface. The disc has a second coupling interface for mating with the first coupling interface. The center alignment mechanism is movable a mounting distance relative to the hub and contacts the disc with the first contact and the second contact to center align the first coupling interface with the second coupling interface. The rotational device is to slowly rotate the hub to angle align the first coupling interface with the second coupling interface to allow the disc to mate and attach to the hub.

A management method of a machining system includes a chuck table, a machining unit, a transfer unit that transfers a wafer onto the chuck table, a camera unit that acquires an image containing a pattern formed on a side of a front surface of the wafer, and an information recording section. The management method is applied when the pattern is recorded in association with machining conditions in the information recording section; and records in the information recording section new machining conditions to be used when machining a new type of wafer, causes an automatic machining program, which automatically machines the new type of wafer, to start, forms an image, which contains a new pattern of the new type of wafer, by the camera unit, and records the new pattern in association with the new machining conditions in the information recording section.

The present invention discloses an industrial high speed micro drill that is made to access remote and inaccessible locations in order to blend, grind, polish and cut materials and parts as determined by visual inspection powered via a pneumatic power source. The high speed drill is deployed by a controlled, articulating guide tube that acts in a multidirectional fashion to direct the action of the assemblage and allow for discrete manipulation of the pneumatically powered drill while harboring a channel and pneumatic power source carrying rubber tubing.
