Abstract
A machining assembly and a method of cutting a tubular member is described which includes a cutting tool and a tubular member holder, wherein the linear and rotational displacement of the cutting tool and the tubular member are controlled with respect to each other by two independent mechanisms. The assembly further includes a third mechanism for controlling the radial displacement of the cutting tool with respect to a longitudinal axis of the tubular member.
Claims18
A machining assembly comprising a body member, and a tubular member holder for holding a tubular member having a longitudinal axis, wherein the tubular member is held stationary by the tubular member holder such that the longitudinal axis of the tubular member is horizontal;
- the body member comprising a moveable cutting tool for cutting the tubular member, the cutting tool being linearly moveable with respect to the tubular member by a pair of linear displacement mechanisms, said linear movement being along an axis parallel to the horizontally arranged longitudinal axis of the tubular member, and rotationally moveable with respect to the tubular member by a rotational movement mechanism;
- the rotational movement mechanism and the pair of linear displacement mechanisms being operable by actuation of respective first and second power means, the first and second power means being actuable independently of each other, so that the pair of linear displacement mechanisms and the rotational movement mechanism are independent from one another;
- wherein one linear displacement mechanism is provided at each side of the body member, and wherein the said pair of linear displacement mechanisms and the cutting tool are all aligned on the same horizontally arranged plane.
A method of cutting a tubular member comprising supporting a tubular member having a longitudinal axis with a tubular member holder wherein the tubular member is held stationary by the tubular member holder such that the longitudinal axis of the tubular member is horizontal;
- providing a moveable cutting tool;
- providing for linear displacement of the cutting tool with respect to the tubular member in the form of a pair of linear displacement mechanisms wherein one linear displacement mechanism is provided at each side of the body member, said linear movement being along an axis parallel to the horizontally arranged longitudinal axis of the tubular member and wherein the said pair of linear displacement mechanisms and the cutting tool are all aligned on the same horizontally arranged plane;
- providing for rotational movement of one of the tubular member and the cutting tool with respect to the other;
- and
- the linear displacement and rotational movement being independent of one another by use of a first and second independent power means.
