PCM Group Home Company Services Machinery Processing Contacts Machining ›Turning The turning is a process of industrial production obtained by chip removal. Turning is defined by a rotary motion of the piece and a mostly rectilinear motion of the tool. The cutting edge of the tool penetrates the material of the workpiece and detaches the excess part ( allowance ), thus forming a chip. EuroProMec Srl specializes in small and medium-sized turning operations. Types of turning : According to the surface to be obtained, the turning is divided into: flat turning (or facing ): flat surfaces perpendicular to the rotation axis of the piece conical turning : conical surfaces cylindrical turning : cylindrical surfaces coaxial with the rotation axis of the piece helical turning : helical surfaces, eg threading on the lathe form turning (or profiling ): surfaces of complex contours According to the position of the tool it is distinguished in: external turning : machining of the external part of the piece internal turning : machining the inside of a hollow piece According to the degree of finish, the processing is called: roughing : first stages of processing finishing : last stages of processing Euro Pro Mec Srl Srl - Via Curiel, 10 - 61033 Fermignano (PU) - VAT number 01462590413 credits This site or third-party tools used by this make use of cookies necessary for the operation and useful for the purposes described in the cookie policy.
