A reaming apparatus for reaming pipe may include a body having a planar front surface, an annular groove defined in the planar front surface of the body and concentric with a center of the body, and a straight groove defined in the planar front surface of the body, radially aligned with the center of the body, and intersecting the annular groove. The straight groove may pass through the center of the body. The reaming apparatus may include a reaming blade having a planar front surface and at least one notch defined in the planar front surface of the reaming blade, the at least one notch being positioned on the reaming blade to substantially align with the annular groove when the reaming blade is disposed within the straight groove. The reaming apparatus can be removably mounted to a pulley of a bandsaw to ream pipe under the power of the bandsaw.

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).

A redressing device (100) for redressing a tapered portion (12) of an orthopaedic implant (10) comprising: a grinding member (110) adapted to engage the tapered portion (12); an adjustable guide element (130) for defining, at least in part, the degree of redressing required for said tapered portion (12) by a user; and a drive shaft (120) for driving movement of said grinding member (110). A device for retaining debris produced during redressing a tapered portion (12) of an orthopaedic implant (12), a surgical kit for redressing a tapered portion (12) of an orthopaedic implant (10) and a method of redressing a tapered portion (12) of an orthopaedic implant (10) are also provided.

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.

One aspect of the invention provides an injection-molded reamer including: an injection-molding parting line; and one or more shafts having a maximum cross-sectional dimension and a length-to-maximum-cross-sectional-dimension aspect ratio of 1:1 or greater. Each of the one or more shafts includes either: (A) one or more axial cross profiles including: a first bar having the maximum cross-sectional dimension; and a second bar having a cross-sectional dimension less than the maximum cross-section dimension, wherein the second bar is parallel to the injection-molding parting line; or (B) one or more axial elliptical profiles including: a major axis having the maximum cross-sectional dimension; and a minor axis having a cross-sectional dimension less than the maximum cross-section dimension, wherein the minor axis is parallel to the injection-molding parting line.

The present disclosure provides a deburring apparatus and a deburring method that does not require a positioning engagement part that is engaged with a fixed part of a machine tool. The deburring apparatus (10) includes a housing (1) with a shank (11), a transmission rod (3), a recovery rod (5), a tilting shaft (4), a spring (6), a holder (7), and a rotary-to-rectilinear motion conversion mechanism (9) with a plunger (8). The spring forces the recovery rod toward the tilting shaft. The holder for fixing the cutter (101) is arranged on the tilting shaft in a manner rotatable through a predetermined rotation angle. The rotary-to-rectilinear motion conversion mechanism separates the first flange portion from the second flange portion and brings the plunger into contact with the recovery rod on the tilting axis (43) when the holder rotates in a direction opposite to the rotation direction of the shank (11).

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).

A tip dresser cutter including a circumferential portion having a circular shape rotatable about an axis of rotation, a center portion located radially inward from the circumferential portion proximate the axis of rotation, and a cutting flute extending radially between the center portion and the circumferential portion. The cutting flute including a leading edge, a trailing edge, a radially inward canted surface extending between the leading edge and the trailing edge. The radially inward canted surface includes a first section extending between the center portion and a first location on the cutting flute and a second section extending between the first location on the cutting flute and a second location on the cutting flute. The second section of the radially inward canted surface including a curved portion that is parallel to a plane of rotation of the cutting flute.
