A component according to the disclosure may include a body having an aperture therein for receiving one of a turbomachine shaft or a lathe chuck, wherein in response to the body being coupled to the lathe chuck, the aperture is oriented substantially axially relative to an axis of rotation of the body with the lathe chuck; and a flange coupled to and in direct axial contact with the body, the flange including a surface that extends axially relative to the axis of rotation of the body, wherein the surface of the flange comprises a matingly engageable face configured to contact an axially aligned surface during operation of the component and having a sanding indentation thereon, wherein a surface roughness of the surface of the flange is less than a surface roughness of a remainder of the component.

The invention relates to a machine tool, hi particular a lathe grinding machine, comprising a tool spindle, a spindle motor and a tool clamped in a covet, with which tool a workpiece may be machined which may be moved in several axes relative to the tool, and comprising a control device for the tool spindle which controls the spindle motor. A spindle load detection device (24) which is connected with the control device (20) is provided and the control device (20) compares the output signal (26) of the spindle load detection device (24) with a predetermined threshold value (50), said threshold value (50) being below, in particular at least 20% below, the breaking load (54) of the tool (18). The control device (20) turns off the spindle motor (14) when the output signal (26) of the spindle load detection device (24) exceeds the threshold value (50).

The present invention generally relates to assembly equipment of valve body, especially to riveting and grinding assembly for nozzle of screw shaft valve. The invention may include a rack, a power control box, a turntable and a turntable divider. A carrier assembly which engages with the screw shaft valve body is installed on the edge of the turntable with uniform distribution. On the center part of the turntable, a support shaft which is installed on and fixed with the rack is vertically interposed and on the top of the support shaft, an upper supporting disc is installed. A valve pipe feeding device, a valve pipe preloading device, a valve pipe riveting device and a valve pipe grinding device which engage with the carrier assembly are installed on the said rack on the rotational direction of turntable. As the threaded pipe is put into the carrier assembly by valve pipe feeding device, the carrier assembly rotates counterclockwise along the turntable and rotates to the valve pipe feeding device to the press threaded pipe into the valve seat. Thereafter the carrier assembly rotates the valve pipe riveting device and rivets threaded pipe with a valve flange in order to finish assembling process. Finally, the carrier assembly rotates the valve pipe grinding device to grind nozzle of valve to finish grinding and riveting process of threaded pipe with high positioning accuracy of assembly and marvelous hermetic sealing.

A lathe sanding disk is defined as an attachment to a chuck provided for use on a lathe device. The lathe sanding disk includes a generally circular form and has a substantially planer front face and a rear face positioned opposite of the rear face. An engagement flange is formed on the rear face of the disk. The engagement flange includes an inner flange surface that is adapted to receive the corresponding engagement surfaces of the lathe chuck. The engagement of the chuck with the engagement flange secures the disk to the chuck for rotation by the lathe. Upon engagement on the chuck, the front face of the disk forms an exposed work surface.

The present application provides a grinding disc and a substrate cleaning device. The grinding disc includes a thickness self-adaptive layer and a base layer and a grinding plate fixed on two opposite surfaces of the thickness self-adaptive layer respectively. The base layer is connected to the grinding head. The grinding plate contacts a product to grind and clean the product. The thickness self-adaptive layer can deform based on a pressure applied by the grinding disc to the product to be cleaned such that the grinding disc completely contacts a surface of the product to be cleaned to make a cleaning area of the grinding disc achieve 100%, which can improve a cleaning rate of the product.

A component according to the disclosure may include: a rotatable body having an aperture therein for receiving one of a turbomachine shaft or a lathe chuck, wherein the aperture is oriented substantially axially relative to an axis of rotation of the rotatable body; and a flange coupled to and in direct axial contact with the body, the flange including a surface that extends axially relative to the axis of rotation of the body, wherein the surface of the flange comprises a matingly engageable face configured to contact an axially aligned surface during operation of the component, the matingly engageable face having a burnishing indentation thereon, wherein a surface roughness of the surface of the flange is less than a surface roughness of a remainder of the flange, and wherein a compressive stress of the surface of the flange is greater than a compressive stress of the remainder of the component.

Embodiments of the present disclosure provide surface treatment tools, methodologies, and/or repaired turbomachine components. A surface treatment tool according to the present disclosure can include a lathe assembly having a lathe chuck for receiving a component thereon, wherein the lathe chuck rotates the component about a first axis of rotation, and wherein the component includes an exposed axial target surface; and a sander or burnishing tool coupled to the lathe assembly and including a sanding or burnishing surface thereon, coupled to a drive system, wherein the sanding or burnishing surface rotates about a second axis of rotation substantially non-parallel with the first axis of rotation, such that the sanding or burnishing surface selectively contacts the target surface of the component to yield a polished target surface.

A sanding tool is adapted to be attached to an existing wood board molding machine. The sanding tool provides a rotating sanding drum which removes imperfections from the profile of the molding as it exits the molding machine. The sanding drum is height adjustable and is powered by an electric motor.
