A peeling apparatus for at least partially removing an external circumferential surface of an approximately cylindrical body is provided. The peeling apparatus includes: a C-shaped or C-like shaped base body, which has two free ends to form a peripheral opening, the cylindrical body being insertable between the two free ends and positionable concentrically in relation to a center of an incircle defined by the internal face of the base body; at least one external bearing mounted on an external axis positioned at each of the free ends, the external bearing abutting the cylindrical body when the body is positioned concentrically in relation to the center of the incircle; at least one central bearing attached to or positioned on the base body, spaced apart from the free ends and on a central axis; and a blade holder into which a blade is insertable so that the blade extends beyond the incircle.

A low surface-roughness part is formed at a first tapered part, and, as a result, the roughness of an opening-edge of a groove part of an internal spline part that opens at the first tapered part is reduced, and surface pressure applied by the opening edge to a tooth of an external spline part can be reduced. As a result, the opening edge of the groove part of the internal spline part can be kept from digging into the tooth, and variation, between products, in the insertion load of a second shaft part can be suppressed.

A flex adapter for a stripping tool for treating plastic pipes or pipes coated with plastic, comprising a base body, at least two fins with respective sops. The fins are flexibly designed such that an outer radial load on the stops produces an opposing spring force; the fins are present in the rear region of the base body. The flex adapter according to the invention further comprises tensioning elements that are arranged integrally in the front region on the base body.

A beveling cutter can include a body with a shaft hole formed through the center. The cutter can also include a plurality of 10 cutter blades arranged at predetermined distances on the circumferential surface of the body, each having a radial primary blade with a radial primary relief angle (a) ranging from about 5 to about 15 degrees and a radial secondary blade with a radial secondary relief angle (b) ranging from about 16 to about 30 degrees. The cutter can also include discharge grooves formed longitudinally between the cutter blades to discharge chips produced in beveling, and a key groove formed at a portion inside the body, in which the helix angle (d) of the cutter blades ranges from about 5 to about 45 degrees. With the beveling cutter, it is possible to smoothly discharge chips produced in beveling and to prevent damage to the cutter blades.

A contact detection module includes a first conductive layer applied to an area of a precision tool tip that processes an object when in contact therewith. A conductive unit of the module includes a first conductive line connected to the object, through which an electric signal flows, and a second conductive line connected to the first conductive layer, through which the electric signal flows. A detection unit of the module includes a signal generation unit to supply the electric signal to at least one of the first and second conductive lines. A detection unit in the conductive unit detects whether the electric signal flows through the entire conductive unit, and determines whether the object and the precision tool tip are in contact with each other, in the lathe wherein the object is cut, based on a change in the electric signal detected.
