A pipe preparation tool has a housing, a motor mounted within the housing, a head mechanism disposed on the housing, a rotatable blade holder disposed within the head mechanism, and a blade attached to the blade holder. The tool may include a power tool battery pack attached to the housing and electrically connected to the motor. Preferably, a pipe may engage the blade in a first orientation and a second orientation opposite to the first orientation. The blade may have first and second opposite cutting edges, wherein the pipe can engage the first cutting edge of the blade when in the first orientation and the second cutting edge of the blade when in the second orientation.

The invention belongs to the technical field of aerospace product machinery manufacturing. Disclosed are on-machine three-dimensional profiling machining device for complex-configured composite material pipelines and an application method thereof. The on-machine three-dimensional profiling of the complex-configured composite material pipelines is In the shape machining device, a precision lifting rod is installed on the linear motion module, and a depth vision system is installed on the precision lifting rod; a precision linear motion table and a radial motion module are installed at the left end of the on-machine measurement hollow machining structure, laser displacement sensor probe, and the eddy current sensor probe is installed on the left end of the hollow machining structure for on-machine measurement through mounting bolts. The invention has the advantages of high integration, simple operation, convenience and practicality.

A pipe preparation tool has a housing (1), a motor (13) mounted within the housing (1), a head mechanism (40) disposed on the housing (1), a rotatable blade holder (42) disposed within the head mechanism (40), and a blade (42B) attached to the blade holder (42). The tool may include a power tool battery pack (12) attached to the housing (1) and electrically connected to the motor (13). A pipe may engage the blade (42B) in a first orientation and a second orientation opposite to the first orientation. The blade (42B) may have first and second opposite cutting edges, wherein the pipe can engage the first cutting edge (42BI, 42BO) of the blade (42B) when in the first orientation and the second cutting edge (42BI, 42BO) of the blade (42B) when in the second orientation.

The present invention relates to a method for manufacturing a plain bearing sleeve (1), having a length (L) of the plain bearing sleeve (1) configured to be greater than the inside diameter (IDM) of the plain bearing sleeve (1) and having a wall thickness (D) of the plain bearing sleeve (1) dimensioned to be smaller than 8% of the inside diameter (IDM) of the plain bearing sleeve (1).The present invention also relates to such a plain bearing sleeve (1), to a plain bearing (10) configured with the plain bearing sleeve (1), and to the use of the plain bearing (10).
