HONING TOOL AND METHOD FOR MACHINING A BEARING PART
A honing tool includes a honing stone holder and a branching lubricant duct arranged in the honing stone holder. The branching lubricant duct has a straight section, first and second diagonal sections connected to and positioned diagonally to the straight section, and first and second transition sections that adjoin the first and second diagonal sections, respectively, and are arranged in a first plane parallel to and spaced from the straight section. The duct also has first and second open end sections continuing from the first and second transition sections, respectively, and directed towards a second plane arranged parallel to the first plane and in which the straight section is situated. In an example embodiment, the honing tool includes a honing stone fixed in the honing stone holder between the first and second transition sections.
MECHANOCHEMICAL CONDITIONING TOOL
A tool (1) for mechanochemical treatment comprises a shaft (10), a number n of working ledges (20), n≧1, and a force application arrangement (2). The force application arrangement (2) is configured for applying a working force (F) on the working ledges (20). The working ledges (20) comprises wear-resistant material with a Vickers number above 800 HV and a Young modulus above 200 GPa. Each working ledge (20) has a contact surface (22) facing away from a main axis (11) and having a surface roughness Ra below I μm. The contact surface (22) has a convex curvature which has a radius of curvature that is at most equal to a closest distance from that point to the main axis. A width of the contact surface (22) is less than r/2n. The working force applied on each working ledge (20) is at least P−L−r/2n, where P=107 Pa and L is the contact surface length.
HONING TOOL AND FINE MACHINING METHOD USING THE HONING TOOL
A honing tool (100) for machining an inner face of a bore in a workpiece with the aid of at least one honing operation comprises a tool body (110) that defines a tool axis (112); a first cutting group (160-1), attached to the tool body, having a plurality of radially feedable first carriers (150-1) that are feedable radially with respect to the tool axis (112) by means of an associated first cutting group feeding system (170-1), wherein each first carrier covers, on its radial outer side, a circumferential angle range of at least 20° and carries, on its outer side (154), a single first cutting material body that is wide in the circumferential direction or a plurality of narrow first cutting material bodies (140-1), which are arranged in a manner spaced apart from one another; and a second cutting group (160-2), attached to the tool body, having a plurality of radially feedable second carriers (150-2) that are feedable radially with respect to the tool axis (112), independently of the first carriers (150-1), by means of an associated second cutting group feeding system (170-2), wherein each second carrier (150-2) carries, on its radial outer side (154), a single narrow second cutting material body (140-1, 140-2). All the cutting material bodies (140-1, 140-2) of the first and the second cutting group are arranged in an axially short cutting region (130) that has a length, measured in the axial direction, which is much less than an effective outside diameter of the cutting groups with the cutting material bodies fully retracted.
Bore finishing tool
A bore finishing tool has an arbor with a tapered outer circumferential surface and a sleeve over the arbor having a tapered inner circumferential surface cooperatively disposed in surface to surface overlaying relation to at least a substantial portion of the tapered outer circumferential surface of the arbor. The sleeve is adjustably movable relative to the arbor for expanding a diametrical extent of the sleeve and has a plurality of internal material relief features at circumferentially spaced locations in the tapered inner circumferential surface extending partially through the sleeve so as to reduce a level of force required for expanding the diametrical extent of the sleeve. Exemplary material relief features include flutes and fractures. The sleeve can also include an external retraction feature enabling application of a retraction force by an external device for reducing the diametrical extent.

FINISHING DEVICE
A finishing device includes a finishing belt, a finishing belt holding device, a first drive configured to rotationally drive a workpiece about a workpiece axis, and a second drive configured to oscillate the workpiece and the finishing belt relative to another along the workpiece axis. The finishing belt holding device has a holding section configured to hold a portion of the finishing belt. The portion has an active area configured to finish a circumferential workpiece surface. The portion extends in a plane which is vertical when referring to the direction of gravity and extends in a horizontal direction when referring to the direction of gravity and when viewing in the running direction of the finishing belt. The finishing device includes a workpiece holding device defining a workpiece holding axis which is vertical when referring to the direction of gravity.

Apparatus and method for honing tubulars of a wellsite
The disclosure relates to a tool for honing a tubular component of a wellsite. The honing tool includes a base operatively connectable to a wellsite component, a honing head supported by the base, honing stones supported about the honing head, and a driver. The honing stones are engageable with an outer surface of the tubular component. The driver rotationally drives the honing head whereby the honing stones hone an outer periphery of the tubular component.

METHOD OF PREPARING A MEAT SKINNER BLADE AND MEAT SKINNER BLADE PREPARED THEREBY
In one aspect, a method of preparing a meat skinner blade is provided which includes: abrading an upper edge of a steel strip to form an angularly-offset two-facet blade edge; and, honing the two-facet blade edge of the steel strip to impart a vertical taper along the two facets of the two-facet blade edge. Advantageously, the subject invention provides a blade for meat skinning, de-membraning, and derinding having, in use, a downwardly-turned edge with vertical tapering. This provides for a robust design capable for more cuts, and, thus, longer use life, than standard meat skinner blades.
