A device for connecting a cooling nozzle to a cooling lubricant supply for a grinding machine includes a central axis, a housing arranged for receiving the cooling nozzle, a rotary-linear transmission and a tube section. The rotary-linear transmission has a drive element, pivotable about the central axis, and a manual lever fixed to the drive element. The tube section is rotationally fixed in the housing and movable along the central axis by the rotary-linear transmission to be pressed against the cooling nozzle. The rotary-linear transmission may be a self-locking transmission. The drive element may have a thread structure which extends over less than a full revolution.

A polishing apparatus is provided with a machining head that is supported to freely move in two horizontal directions; driving devices that enables the machining head to move; a polishing jig that is supported by the machining head to freely move in a vertical direction; a polishing member that is mounted on a lower end portion of the polishing jig; an air cylinder polishing jig moving device that moves the polishing jig and is capable of pressing the polishing member against a tube support plate; and a drive motor that is capable of rotating the polishing jig, thus, simplification of the structure is made possible.

A grinding machine for machining workpieces includes a workpiece headstock and two grinding headstocks. A first grinding headstock has two grinding spindles each with one grinding wheel for grinding first and second planar and non-planar external surfaces. A second grinding headstock has a grinding spindle having a grinding wheel for grinding a central bore in the workpiece, and a clamping device to clamp the workpiece. First, the bore and the first planar and any non-planar external surface are ground on one side of the workpiece. Then, the workpiece is clamped in the bore. The second planar external surface can then be ground in the same grinding machine with one of the grinding wheels of the first headstock. The clamping device attached to the second grinding headstock is such that the central axis of the clamping device is exactly aligned with the central axis of the workpiece headstock.

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).

Disclosed is a device for automatically removing burrs from a riser of an aluminum alloy wheel. The device is composed of a frame, a clamping gear rack structure, a support plate, a servo motor and the like. When a clamping cylinder drives a first sliding plate to move, clamping wheels are controlled to center and clamp the wheel, and the servo motor controls the rotation of the clamping wheels, so that the wheel may rotate while being clamped. When a distance adjusting cylinder drives a second sliding block to move, a first sliding block and the second sliding block move synchronously under the action of a feed gear rack structure, so that a first deburring tool and a second deburring tool move synchronously to adjust the distance between them according to the diameter of a cap slot.
