A chamfering apparatus for opposing end faces of a tubular member. The apparatus includes an abutment member capable of advancing toward or being retracted from a line of extension of the longitudinal axis of the tubular material so as to collide with the end face when advanced, a conveyor for transporting the tubular member toward the abutment member, a chuck provided between the abutment member and conveyor for releasably holding the tubular member on the conveyor, and a cutting tool displaceable relative to the end face of the tubular member received by the abutment member and held by the chuck. The cutting tool is capable of rotating around the longitudinal axis of the tubular member. The cutting tool is equipped with a cutting member adapted to taper cut the outer peripheral edge of the end face as well as a drill having a first cutting edge adapted to taper cut the inner peripheral edge of the end face and a second cutting edge adapted to cut the end face perpendicularly to the longitudinal axis of the tubular member. The chamfering apparatus can be applied to tubular members of different lengths as the end face of each tubular member can be positioned precisely owing to the provision of the abutment member and conveyor and only two cutting tools are required to chamfer three locations on each end face of the tubular member.

A cutting and chamfering apparatus for opposite ends of a tubular member including a cutting and chamfering support for holding horizontally the member, two tables provided respectively at opposite ends of the support, and a cutting machine and chamfering machine mounted in combination on each of the tables.

A degreasing apparatus for an elongated member including a treatment room sequentially divided in an isolated fashion and along the feeding direction of the elongated member into a degreasing chamber, a predrying chamber and a finish drying chamber. At least one pair of rotary brushes are provided in the degreasing chamber. The degreasing chamber is also provided with means for jetting out a degreasing liquid in a direction toward the inlet side of a contact area between the brushes and elongated mechanism. Elastic degreasing members are provided, respectively, at the inlet and outlet sides of the degreasing chamber to remove oil or grease from the elongated member before it enters the degreasing chamber and to wipe off any degreasing liquid remaining on the elongated member prior to passing the same into the predrying chamber. The predrying chamber houses a mechanism for jetting out water or steam against the elongated member while the finish drying chamber is provided with a mechanism to blow hot air against the elongated material and to dry it completely. The above degreasing apparatus can be formed in a reduced size and convenient for coupling with drawing machine and/or roller straightening machine, thus enabling continuous treatment of elongated members. Owing to the mutual isolation of the chambers, their respective treatment media can be saved and the overall processing efficiency can be improved.
