AUTOMATIC TAPPING MACHINES BY REVERSING SPINDLES - INTERNAL THREADS FOR METAL PARTS

The Automatic Tapping Machines are based on the reversible spindle architecture, mechanically driven by lead screw or brushless synchronized motion systems. Internal threads, within the range M2 to M36 can be executed with standard taps in both the technologies, cutting and forming. Modularity is at the base of our machines; in relation to the characteristics of the application, it's possible to place single/double spindles having that way two autonomous working areas. Flexibility is also maximized since the possibility to work contemporary two different parts in a completely autonomous process. Precision in operation is achieved by means the structural rigidity of the frame and the very fine design and engineering of the positioning/clamping devices. Orthogonality and concentricity as well as the other dimensional/geometrical features, are so lifelong guaranteed. In terms of productivity, a configuration with four spindle, with an output rate about 200 pieces/minute, represents the most complete machine architecture.
