EMAG PMD 2 grinds down crankshaft costs
The PMD 2 crankshaft grinder developed by EMAG Naxos-Union is said to drive down manufacturing costs by delivering higher output rates. It is designed for the machining of crankshafts for passenger cars and features twin grinding heads that allow for the simultaneous grinding of two pin or main bearings in a single set-up, using two CBN grinding wheels. According to EMAG, a four-cylinder crankshaft can be machined in less than 2 minutes.
The capacity of the PMD 2 covers small components of up to 500 mm length. The machine is equipped with a direct-driven work spindle, hydrostatic guideways and a linear motor in the X-axis, as well as an in-process measuring control that allows for roundness monitoring and correction in the machine.
The grinding wheels can, if required, be arranged very close together, so that adjoining pin and main bearings can be machined simultaneously.
