A knife sharpener may include a suction cup, a main base, a sharpening set, a first cover, a control handle, and an upper cover. The suction cup is adapted to create vacuum so as to enable the knife sharpener to be attached on a working surface, and a lever extends from a top surface of the suction cup. The main base has different heights of a first portion and a second portion thereon to form a stepped shape. The sharpening set comprises two pieces of sharpening stones which are coupled together to form a sharpening space therebetween. The first cover having appropriate transparency is a board body. The control handle has a second through hole axially penetrating through a central portion thereof, and an abutting block is horizontally extended from the connecting portion to protrude from a rear end of the control handle.

Described is a method for grinding workpieces, which comprise at least one cylindrical and profiled portion each, on one and the same grinding machine. The workpiece is ground initially in a first grinding operation in a first clamping in the grinding machine, said first grinding operation being followed by a second grinding operation once the first clamping has been released and then, before the start of the second grinding operation, a second clamping has been generated.

The present invention relates to a measuring steady rest which has a device for supporting central workpiece regions, in particular, bearing points on shaft parts, in particular crankshafts, and a measurement device integrated therein for directly adjusting the measurement of the workpiece regions before and/or during machining of the shaft parts. The measuring steady rest is preferably designed in the form of a prism, the measurement device being arranged on the bottom of the prism between the lateral flanks of the prism. The present invention further relates to a grinding machine comprising such a measuring steady rest, and to a method for supporting and measuring central workpiece regions on such a grinding machine comprising such a measuring steady rest.

A wheel fixture is disclosed. A main shaft drives a first positioning pull rod on a chuck body to extend and contract in the radial direction via a tightening screw, a clamping jaw is at a position within the travel range of extension and contraction, a wheel is positioned and clamped by the fixture, airtight support blocks are pressed down by the wheel and flush with the support plane of the clamping jaw, at this time, airtight ejector rods press second O rings to prevent air from flowing out of the airtight detection position, a detection system of a machine tool detects a preset air pressure value which indicate that the wheel has been placed correctly, and if the wheel is not placed correctly on the fixture, the machine tool will alarm through the detected pressure feedback.

The method and the device are used for processing a shaft of an apparatus which supports the shaft in rotation. The device is provided with a drive unit which can be attached to the apparatus and has a drive element that can be driven in rotation by a motor and is suitable for coupling to an end of the shaft to be machined. The device also has a holding unit, which can likewise be attached to the apparatus, for at least one of the following units: a supporting bearing unit for supporting the shaft 464 to be machined; a material removal unit for removing material from the shaft to be machined at its bearing point; a material application unit for applying material to the shaft to be machined at its bearing point; and a grinding unit for grinding down the material applied to the bearing point of the shaft to be machined.

The supporting bearing unit, the material removal unit, the material application unit and the grinding unit are operable during rotation of the shaft to be machined by means of the drive unit.

An actuating device (10) actuates jaws (12) of a steady rest (11). The jaws can be used for clamping or supporting a workpiece (13). The actuating device includes a carrier (18) with a mounting side (20) to which the steady rest (11) can be mounted. An outer end (27b) of an actuating part (27) projects away from the mounting side (20) of the carrier (18) and includes a connecting arrangement (29) as the interface for the connection with an input part (14) of the steady rest (11). An inner end (27 c) of the actuating part (27) is movably coupled with a piston (35) of a pneumatic cylinder (36) via a coupling arrangement (34). The coupling arrangement 34 includes a slide (40) that is immovably connected to the piston (35), said slide having on it at least one slotted gate (44). The slotted gate (44) defines a gate path oriented obliquely to longitudinal direction L and to height direction H, along which gate path the at least one gate element (46) can be guided in a movable manner. The gate element is connected to the inner end (27c) of the actuating part (27).

A steady rest for supporting, e.g., bearing points on shaft parts of crankshafts, during the grinding of central and/or eccentric workpiece regions. For the grinding, the steady rest is brought from a retracted position to a supporting position against the workpiece region to support the workpiece region at respective circumferential regions. The supporting parts are each arranged on a lateral flank of a prism opening in a fork-like manner on a steady-rest arm in a fixed position in relation to each other and to the steady-rest arm, the supporting parts thus forming an opening angle to each other. The supporting parts are arranged below center with respect to the longitudinal axis of the workpiece region such that an angle bisector between the two supporting parts has a fixed acute angle to the vertical extending through the longitudinal axis of the workpiece region and the CNC-controlled advancement occurs along said angle bisector. The invention relates to a grinding machine, which has a steady rest described above.

A system includes an abrasion assembly containing one or more abrasion pads configured to clean a faying surface of multiple nutplates, and a shaft attached to at least one of the abrasion pads and configured to rotate some or all of the abrasion pads during cleaning, wherein cleaning includes abrading the faying surfaces with the abrasion pads. The system also includes a base configured to attach to a pressure applicator, and a pressure applicator configured to attach to the base, hold the nutplates such that the faying surface of each nutplate is capable of contacting one of the abrasion pads, and apply pressure to the nutplates such that each of the nutplates contact one of the abrasion pads during the cleaning. Furthermore, the abrasion assembly is configured to rotate the abrasion pads within at least one of the base and the pressure applicator during cleaning.
