Pipe machining apparatuses are provided. In some aspects, a pipe machining apparatus may include a hinge to allow two sections of the pipe machining apparatus to move relative to one another. In another aspect, a support member may be provided to support a pipe machining apparatus on a surface. In a further aspect, a support member may be provided that allows lifting of a pipe machining apparatus in either a horizontal position or a vertical position.

A device for cutting a preferably thick-walled, extruded pipe to length, has at least one cutting tool and a receiving unit for the cutting tool. The cutting tool is radially movable in relation to the extrusion axis, is rotatable via a further component about the pipe to be cut to length, in order to cut the pipe to length, and is in operative connection with a ring element, which ring element can be moved via an axial drive, and the depth of penetration of the cutting tool and the path of movement can be defined using an adjustment unit. The depth of penetration of the cutting tool and the path of movement can be defined via the axial drive, wherein toothed rails can be moved more or less in order to achieve the desired depth of penetration.

In one example, a pipe machining apparatus is provided and includes a frame, a tool carrier coupled to and rotatable relative to the frame, a first machining apparatus including a first tool support and a first tool supported by the first tool support and a second machining apparatus including a bridge member, a second tool support supported by the bridge member, and a second tool supported by the second tool support. The first tool is configured to perform a first machining operation and the second tool is configured to perform a second machining operation different than the first machining operation. The first machining apparatus and the second machining apparatus are interchangeably couplable to and rotatable with the tool carrier.

A lathe includes a main shaft, a moving shaft, a cutter mounted on the moving shaft, and a clamping assembly. The cutter is capable of telescopic translation relative the moving shaft. The clamping assembly includes a cylinder mounted on the cutter, an assembly member mounted on the cylinder, a moving member, and at least two clamping members. The cylinder defines an inner cavity, and a first air intake and a second air intake communicated to the inner cavity. The moving member is movably mounted in the inner cavity and partially received in the assembly member, and capable of telescopic translation relative the assembly member. The clamping members are movably mounted on the assembly member and engaged with the moving member. The clamping members are translatably urged by the moving member in a direction relative the axis defined by the assembly member.
