Abstract
A machining assembly and a method of cutting a tubular member (19) are described which includes a cutting tool (8) and a tubular member holder (4, 5), wherein the linear and rotational displacement of the cutting tool (8) and the tubular member (19) 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 (8) with respect to a longitudinal axis of the tubular member (19).
Claims19
A machining assembly comprising a body member, and a tubular member holder for holding a tubular member;
- the body member comprising a cutting tool for cutting the tubular member, the cutting tool and the tubular member being linearly moveable with respect to each other by a linear displacement mechanism, and rotationally moveable with respect to each other by a rotational movement mechanism;
- the rotational movement mechanism and the linear displacement mechanism 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 linear displacement mechanism and the rotational movement mechanism are independent from one another.
A machining assembly as claimed in either preceding claim, further comprising a stationary housing.
A machining assembly as claimed in any preceding claim, wherein the cutting tool and the tubular member are linearly moveable with respect to a longitudinal axis of the tubular member.
A machining assembly as claimed in any preceding claim, wherein the rotational movement mechanism further comprises a drive shaft which is rotatably mounted within the body member.
A machining assembly as claimed in any preceding claim, wherein the cutting tool is further moveable in a radial direction with respect to the longitudinal axis of the tubular member by a radial displacement mechanism.
A method of cutting a tubular member comprising supporting a tubular member with a tubular member holder;
- providing a cutting tool;
- providing for linear displacement of one of the tubular member and the cutting tool with respect to the other;
- 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.
