Crankshaft Grinder, Twin-Grinding Head

EMAG Naxos-Union has launched a new Crankshaft Grinder, Model PMD 2 that provides for high output rates and impresses with its excellent price-performance ratio. The PMD 2 complements the EMAG crankshaft grinder program. 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 grinding wheels. Its capacity covers small components of up to 500 mm length. The basis for the PMD 2 is the well-proven “Series 2” of EMAG Naxos-Union and EMAG KOPP. These machines combine high-tech grinding technology with precision, great efficiency, process integrity and simple operation. In PMD 2, two CBN grinding wheels machine crankshafts to the highest precision. To achieve this, the machine is equipped with a direct-driven workspindle, 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 technology also scores with its simultaneous use of two grinding wheels. The twin-tool process opens up a number of possibilities for the user, depending, of course, on component and machining requirements. Two pin bearings or main and pin bearing are machined simultaneously, leading to a reduction in cycle times. The machine is also of compact but flexible construction.
