Features of the PM 2 / PMD 2:
++ CBN technology also for grinding with radii and shoulders
++ Oscillating stroke grinding of pin bearings with centrally c lamped workpieces
++ Maximum productivity through
Machining Automobile Crankshafts with the PM 2 / PMD 2 Standard features include 30 kW motor spindles for the grinding wheels and a workpiece headstock with a direct drive unit, as well as a stable tailstock and a linear motor for the X-axis.

Integrated Quality Management Correction values, determined using the EMAG "Roundness Testing“ software package, are used to optimize the grinding process.
»» Roundness measurement: using the post-process diameter measuring device on the finish-ground bearing »» Roundness correction: correction values are calculated and confirmed by the operator »» Grinding with optimized values: the next workpiece is then ground using the corrections »» Optional: processing of correction data from an external measuring machine possible

Main features of the PM 430 / PM 460
++ Oscillating stroke grinding of
large crankshafts: grinding main and pin bearings on the same machine.
++ Use of conventional aluminum oxide grinding wheels or CBN grinding wheels
++ High productivity coupled with high flexibility
Machining Large Crankshafts with the PM 430 / PM 460 The PM 430 / PM 460 are fitted with linear motors and hydrostatic guideways in the X- and Z-axes to ensure maximum dynamics and excellent grinding results. The workpiece spindle is directly driven by a torque motor. Workpieces with a length of 3,000 mm or longer are powered from both sides. When using aluminum oxide, the grinding wheel is powered by a motor and belt drive. CBN grinding wheels are powered through a motor spindle. The fully cased machine is fitted with large automatic front doors, providing excellent access to the machining area.
++ Fully automatic, semi-automatic or manual grinding processes possible
++ In-process diameter m easurement for maximum precision and roundness check in the machine
PM 430 / PM 460
++ Universal axial and radial
alignment of the shaft prior to grinding to ensure the highest possible component quality and maximum flexibility
++ Very rigid 2-axis NC steady rests for excellent crankshaft support
