A honing tool or device having a generally cylindrical body includes a plurality of axially extending webs to which are attached a like plurality of curved honing blades. A portion of the external surface of each blade remote from the attachment point includes an abrasive coating. The radius of curvature of the portion of the blades including the abrasive coating is nominally the same as the radius of the desired finish diameter of the bore. Resilient dampers are disposed behind the blades in the body to dampen vibrations. An additional plurality of webs may be disposed behind the blades to limit their inward translation. A double or tandem honing device includes a pair of the just described honing tools which are arranged in axially spaced apart relationship on a common shaft.

A head assembly of a honing tool includes a carrier having a proximal end connectable to a spindle, a distal end, and a plurality of stones. The head assembly also includes a pilot cap connected to the distal end, and defining an end face and a sidewall. A transition surface defined by the pilot cap extends between the end face and the sidewall. The transition surface extends at a first angle forming a first angled relief and then at a second angle forming a second angled relief.

To provide a method for forming an anchor hole and a diameter expansion device by which a centrifugal force can be appropriately adjusted when a cutting-blade portion is moved in a radial direction by the centrifugal force to grind a diameter expansion portion. In a method for forming an anchor hole for a post-installed anchor in which a diameter expansion drill bit is inserted and rotated in a prepared-hole portion bored in a concrete fixing body and a cutting-blade portion of the diameter expansion drill bit is moved in a radial direction by a centrifugal force to grind a part of the prepared-hole portion to form a diameter expansion portion, the minimum value of the centrifugal force applied to grind the diameter expansion portion is 0.75 N and preferably 1.1 N.

A honing tool having an at least partially tubular tool body and includes a cutting region with at least one honing-stone receiving opening running through the tool body from inside outwards for receiving an individual honing stone. The dimensions of the honing-stone receiving opening and of the honing stone are sized and configured so the honing stone can be received between within the honing-stone receiving opening so as to be radially movable and substantially without substantial play in the circumferential direction of the tool body. The honing tool has a honing-tool-restoring system which comprises at least one resilient restoring element. When the honing stone is installed, the honing-stone-restoring system engages with the honing stone such that a radial force from outside acts inwards, pressing the honing stone against die feed element.

A tool system for configuring honing tools includes at least one tool body that defines a tool axis and an axial bore arranged coaxially to the tool axis, as well as multiple transverse bores oriented perpendicular to the tool axis, wherein the transverse bores form multiple groups around the circumference of the tool body, each group having at least two axially spaced apart transverse bores. The tool system further includes multiple sets of support rail units with guide pins for introducing into transverse bores of a bore group, and also includes at least one set of bolt guide elements for mounting on the tool body, with each set having a bolt guide element for each transverse bore provided for receiving a guide bolt, with a guide bore formed therein, which, when the bolt guide element is mounted on the tool body, runs coaxially with the transverse bore.

Disclosed is a machining unit for machining a bearing component. The machining unit includes an industrial robot and at least one abrasive tool. The at least one abrasive tool is coupled to the industrial robot and a controller. The controller is configured to control a movement path of the at least one abrasive tool such that a contact of the abrasive tool is in the normal direction to a surface of the component.
