Abstract: A machining device for machining the lateral surface of an approximately cylindrical object in portions thereof includes a chain for annularly surrounding the object to be machined. The chain consists of at least two hingedly connectable chain links, one of which is a tool holder having at least one tool for machining the lateral surface. The device also includes support rollers for rolling on the lateral surface. The at least one other chain link is a chain connecting link. The chain links are connectable in such a way that they form a closed chain ring around the object to be machined. The machining device further includes a feed adjuster capable of reversibly adjusting an axial position of facing ends of two chain links parallel to the axis of the closed chain ring relative to each other.
Abstract: A peeling tool designed for at least partially stripping the outer peripheral surface of rotationally symmetric objects, in particular cylindrical plastic pipes, with the peeling tool featuring a peeling head with a drive shaft having a longitudinal axis and coaxially to this drive shaft arranged cylindrical blade roller. The cylindrical blade roller moves with the drive shaft. The peeling tool also featuring at least one peeling blade inside the blade roller with the peeling blade having a cutting edge which extends beyond the blade roller surface and defines the maximum outer diameter of the peeling head. The peeling tool also features two cylindrical guide elements with longitudinal axes, which are mounted to the face sides of the blade roller in a coaxial arrangement.
