The invention is a bi-fluid actuator for precise bi-directional movement and positioning of a mechanical object or load. The bi-fluid actuator includes a pneumatic fluid container defining opposed first and second pneumatic fluid chambers, and having a first mechanical object secured between the chambers; a hydraulic fluid container defining opposed first and second hydraulic fluid chambers, and having a second mechanical object secured between the first and second hydraulic chambers; a pneumatic fluid controller; and, a hydraulic fluid controller. Directing pneumatic fluid into either the first or second pneumatic chambers, while controlling flow of hydraulic fluid between the first and second hydraulic chambers, controls movement and positioning of the mechanical objects which may be secured to a load.

A process according to claim 13, further comprising the step of subjecting the skiving blades to preliminary tension against said common body. 15. The process according to claim 13, wherein said common body is subjected to preliminary tension in a first operating position relative to the skiving blades. 16. A process according to claim 15, further comprising the step of pressing said common body into a second relative position to displace the skiving head in a peeled-out out body without machining the body by imposing an external force against the preliminary tension, in which position the radial distance between the cutting edges and the central axis of the skiving head is smaller than in an operating position. 17. A skiving head for skiving out cylinders and cylinder tubes comprising: a common body having a substantially conical shape and which is movably disposed in said skiving head; and at least three skiving blades being arranged floating and radially movable in the skiving head in relation to the skiving head by said common body, said skiving blades being positioned on a substantially same plane wherein said at least three skiving blade are in contact with said common body so that a movement by said common body in an axial direction causes a corresponding movement of said at least three skiving blades in a radial direction. 18. A skiving head for skiving out cylinders and cylinder tubes comprising: a common body having a substantially pyramidal shape and which is movably disposed in said skiving head; and at least three skiving blades being arranged floating and radially movable in the skiving head in relation to the skiving head by said common body, said skiving blades being positioned on a substantially same plane wherein said at least three skiving blade are in contact with said common body so that a movement by said common body in an axial direction causes a corresponding movement of said at least three skiving blades in a radial direction. lication.
