Abstract
The machining device is for machining the material of a pipe system that has a joint area between a pipe that has a smaller inner diameter and a pipe that has a larger inner diameter. The device has protruding parts that have been adapted to position the device inside the pipe that has the smaller diameter. A steerable actuator is adapted for removing material from the joint area and steering device for controlling the direction of the machining device in relation to the longitudinal axis of the pipe that has the smaller inner diameter while removing material from the joint area. The method is for machining material of the joint area that has a thinner and a thicker pipe.
Claims11
A machining device for machining the material of a pipe system, wherein the pipe system has a joint area between a pipe having a smaller inner diameter and a pipe having a larger diameter, the machining device comprising:
- a rotary spindle driven to rotate about a rotation axis;
- protruding parts protruding radially from the rotary spindle and adapted to position the machining device or at least a part of the machining device inside the pipe having smaller inner diameter, the protruding parts each comprising a flexible lamella having an abrasive surface for machining the smaller inner diameter;
- steerable, actuator operable means, detachably attached to an end of the rotary spindle, for removing material from the joint area to define a hole in the joint area, and
- a steering device having means for controlling a direction of the rotation axis of the machining device in relation to a longitudinal axis of the pipe having the smaller inner diameter while removing material from edges of the hole with the protruding parts.
