Apparatus for machining a tubular piece
First Claim
1. An apparatus for machining, or cutting, a tubular piece, comprising:
- a frame element;
support rollers, which are associated with the frame element, configured to support a workpiece and rotate the workpiece around a longitudinal axis of the workpiece; and
a machining unit adapted to be movable towards the workpiece, wherein the machining unit comprises support wheels adapted to bear against the workpiece, wherein the machining unit is arranged to link up with the frame element through use of an auxiliary frame element, the auxiliary frame element being adapted to be clamped to the frame element via at least two support points at least two different distances from the support rollers, and said support rollers are located between said at least two support points,wherein the support wheels are adapted to be movable essentially towards or away from the support rollers independently of at least one cutting tool, and wherein the support wheels are adapted to clamp themselves in at least two different positions with respect to the machining unit.

Abstract
An apparatus for machining a tubular piece, wherein the apparatus includes a frame element, support rollers, which are associated with the frame element, support a workpiece and rotate the same around its longitudinal axis. In addition, the frame element is provided with a machining unit adapted to be movable towards and away from the workpiece. The machining unit includes a tool member, such as for example a cutting tool, as well as support wheels adapted to bear against a workpiece. The machining unit is arranged to link up with the frame element through the use of an auxiliary frame element adapted to clamp itself thereto at not less than two support points, for example through the use of a self wedging assembly implemented with an indentation.

15. A manufacturing method for an apparatus, comprising:
-
providing a frame element; linking up support rollers with the frame element; supporting a workpiece and rotating the workpiece around a longitudinal axis of the workpiece, with the support rollers; linking up a machining unit with the frame element; moving the machining unit towards the workpiece; bearing support wheels of the machining unit against the workpiece; linking up the machining unit with the frame element through the use of an auxiliary frame element; and clamping the auxiliary frame element to the frame element via at least two support points at at least two different distances from the support rollers, and said support rollers are located between said at least two support points, wherein the support wheels are moving essentially towards or away from the support rollers independently of at least one cutting tool, and wherein the support wheels are clamping themselves in at least two different positions with respect to the machining unit.
