A pipe cutting apparatus comprises at least one work-holding fixture and a cutting device pivotable about the axis of the pipe to be cut and having a cutting tool and drive. The cutting device is movable manually and/or by means of at least one transmission gearing for the feed of the tool about the pipe to be cut. The transmission gearing has a spur gear interacting with a crown gear.

Pipe cutting apparatus

A pipe end machining unit (,) is provided with a housing (,) which is composed of two parts (,a,,b). The clamping device (,) and the tool support (,) are supported in the upper housing part (,a). The lower housing part (,b) is of modular design and accommodates at least those components (,) which are relevant for controlling the motor. With a pipe end machining unit (,) designed in such a manner, conversion from an electrical drive to a pneumatic drive, or vice versa, is possible in a simple manner and within a very short time. Furthermore, the essential parts can be standardized, which results in major advantages from the manufacturing point of view.

Pipe end machining unit

Device for the machining of tube ends

Device for welding tubular components of plastics material

A treating device for mechanically treating the outer circumferential surface of tubular components. The treating device includes a grinding tool and is rotatably mounted on an internal chuck. The internal chuck is chucked by means of chuck jaws concentrically relative to the inner diameter of the tubular component. The grinding tool includes a drive shaft and a drive motor and is eccentrically mounted in a bushing which can be swivelled by means of a worm drive. By swivelling the grinding tool, the grinding tool is moved toward the tubular component for the appropriate processing depth. Subsequently, the outer surface of the tubular component is treated by rotating the treating device about the internal chuck.
