Internal skiving and burnishing tool STGA-T

roller

Machining for cold drawn or hot rolled and drilled pipes. Technology with STGA-T: • Dual combined Skiving and Roller Burnishing STGA-T with movable skiving head These tools are used for the internal finishing of cylinder tubes. The tool eliminates irregularities in circular form such as rippling, that occur during the manufacturing process of hydraulic cylinders. During the roller burnishing process the tool also creates a perfect surface. The combined tool STGA-T can achieve a diameter range of Ø 40 up to Ø 250 mm and a length up to 12m. With the operating of STGA-T the tool can achieve a diameter range of Ø 125 up to Ø250 and a maximum length of 4 m. Larger diameters on request. The tool STGA-T is equipped on the head with three viper plates and at the skiving head with three more skiving knife plates. Tool STGA-T is equipped with 3 boring plates mounted to the boring head, as well as six viper plates mounted to the skiving head. The exchange of the plates is a quick and simple. STGA-T tools has a cutting efficiency of up to 3 mm in diameter. STGA-T tool has a cutting ability of up to 8 mm. The excess material will be removed during the boring process and the skiving head will remove the rest up to the set diameter and prepares the optimal surface for the roller burnishing process. Rollers placed in a cage on the tools circumference are forced into the cylinder´s inner wall thus smooth the surface of the cylinder tubes. The forming process increases hardness and enhances, the wear and the fatigue resistance of surface subjected to dynamic working load.
