Junker this circular grinding method with CBN grinding wheels, which opens up significant productivity benefits from the long service life of the grinding wheel, especially at high volumes. In addition, the simultaneous removal takes on the entire Schleswig-Holstein, which provides both in mass production and in small batches for significantly reduced processing times. Hsdpfx Afjt Uw Avocji The grinding process with JUPITER When centerless grinding, there are two grinding processes: the through grinding and plunge. Both methods are possible with the JUPITER. Applications through grinding: Pin and Bushings Body, rings, smaller rings, piston parts (eg compressors), waves with constant diameter piston rods (eg shock), Small piston for hydraulic and fuel injection, precision wires and rods, piston pins. Applications Plunge: Rotor shafts, transmission parts, bearing surfaces of camshafts, tube and pipe fittings for composite camshafts, universal joints, parts for needle injection, valve stems, barrel rolls. *
