摘要： A refacing tool includes a feed assembly that holds a first set of cutters positioned for refacing the inner shoulder of a pin or box end of a tubular and a second set of cutters positioned for refacing the outer shoulder of the pin or box end. The axial spacing between the first set of cutters and the second set of cutters is fixed and determined by the geometry of the feed assembly. The refacing tool can simultaneously reface the inner shoulder and the outer shoulder, as well as chamfers.

摘要： The present disclosure relates to a weld groove forming method and a hollow article. The weld groove forming method may include: (S110) determining whether a side end of a pipe may be processed into a form of a true circle by using a sensor robot; and (S220) forming a weld groove in a form of a true circle at the side end of the pipe by using an automatic beveling machine when the sensor robot determines that the side end of the pipe may be processed into a form of a true circle in the step (S110).

摘要： A system for electrode dressing including a cutter with a rim and a center land supported on the rim by a number of flutes defining openings between the flutes. The flutes and the center land define a cutting profile of the cutter. The cutter is configured to rotate about an axis passing through the center land. Cutting edges are disposed on the flutes and are made of a first material having a Vickers hardness (HV) of at least 850 HV, overlaid by a second material having a Vickers hardness of at least 3200 HV. The cutter profile comprises a face cutting profile extending radially outward from the axis that is disposed at an angle of less than six-degrees relative to a radial normal of the cutter.

摘要： A rotary cutter for cutting damaged threads of a bolt includes a body rotatable about a rotating axis. The body includes an inner periphery delimiting a conic cutting space. The body further includes at least one cutting blade, an evasive groove, an evasive portion, a scrap discharge groove, a scrap guide groove and a scrap discharge orifice on the inner periphery delimiting the cutting space. The at least one cutting blade forms a ridge. The evasive groove and the scrap discharge groove are respectively located on a rear side and a front side of the at least one cutting blade along a circumferential direction of the inner periphery of the body. The scrap guide groove extends between the evasive groove and the scrap discharge orifice.

摘要： A pipe spinning power drill accessory a stem, shaft, first knurled assembly, second knurled assembly, first state, and second state. The first knurled assembly and the second knurled assembly are each cylindrically shaped. The first knurled assembly is centrally affixed to the stem. The shaft is centrally affixed to the first knurled assembly opposite the stem. The second knurled assembly is centrally affixed to the shaft opposite the first knurled assembly. The first knurled assembly and the second knurled assembly each selectively expand laterally. In the first state, the first knurled assembly and the second knurled assembly are each not laterally expanded. In the second state, at least one of the first knurled assembly and the second knurled assembly are laterally expanded. The stem is configured to be inserted into a chuck of a power drill. The stem is cross-sectionally hexagonally shaped and includes a region of decreased diameter.

摘要： A chip scattering prevention cover (1) is attached to a head portion (6b) of a rotary cutter (6). The cover (1) includes an annular portion (1a) configured to be detachably fitted over an outer peripheral edge of the head portion (6b), and a plate portion (1b) extending inwardly of the annular portion (1a) from an inner circumference portion of the annular portion (1a). The plate portion (1b) is configured to cover a region of a cutout gap (6e) of the rotary cutter (6) corresponding to the head portion (6b) with the annular portion (1a) being fitted over the head portion (6b). The annular portion (1a) and the plate portion (1b) are flush with a surface of the head portion (6b) when the annular portion (1a) is fitted over the head portion (6b).

摘要： Adjustable feed mechanisms, machining assemblies including the same, and associated methods. An adjustable feed mechanism includes a plurality of cam segments and a cam lifter configured to pivot each cam segment about a corresponding cam pivot point. An adjustable feed mechanism additionally includes a cam follower and a feed output assembly. The cam follower moves along the cam segments sequentially and is pivotally coupled to the feed output assembly. The cam follower pivots through a cam activation angle when moving along a given cam segment to produce the feed output. A machining assembly includes a mount assembly, a rotary element, and an adjustable feed mechanism. A method of utilizing a machining assembly to machine a work piece includes engaging the work piece with a machining assembly, positioning the tool head with respect to the work surface of the work piece, and machining the work surface.
