At JUPITER, grinding means less cylindrical grinding, with CBN too on request. JUNKER combines this cylindrical grinding method with CBN wheels to create significant productivity advantages, especially with large batch sizes. This is coupled with the simultaneous abrasion along the entire grinding wheel width, which ensures considerably reduced machining times for both large and small-scale production.

There are two principles for less grinding: feed-through grinding and plunge-cut grinding. JUPITER can achieve both principles.

Bolts and bearing supports, large rings, smaller rings, piston components (e.g. for compressors), shafts with constant diameter, piston rods (e.g. for shock absorbers), small pistons for hydraulic and injection systems, precision wires and rods, piston bolts.

Rotor shafts, gearbox parts, bearing surfaces of camshafts, pipe components for composite camshafts, cardan joints, needle components for injuction systems, valve shanks, spherical rollers.
