Not only do JUNKER and ZEMA cylindrical grinding machines master all fundamental grinding processes such as longitudinal, plunge-cut and angular plunge-cut grinding, they also handle more complex processes such as profile, screw, thread and plane surface grinding. External and internal grinding processes are also possible and can be combined. Typical workpieces machined on cylindrical grinding machines include all kinds of shafts and bolts, such as gear, turbocharger and rotor shafts. The cylindrical grinding machines from JUNKER and ZEMA are ideal for prototype, small, and large scale production.
