PM 430 / PM 460

Quality – Productivity – Flexibility: Crankshaft Grinding with PM 430 / 460

The PM 4 series is for the crankshaft grinding of crankshafts with a length of up to 3,000 / 6,800 mm (118,1 / 267,7 inch).

The grinder PM 430 / PM 460 features linear motors and hydro-static guideways in X- and Z-axis, making them highly dynamic and guaranteeing excellent grinding results of crankshaft grinding. The workpiece is driven from both ends, using either drivers or hydraulic chucks, depending on the application. The work spindle is directly driven by a torque motor.

The grinding spindle is designed like a motor spindle with a maximum power rating of 100 kW. Higher torque rates are achieved with an optional auxiliary motor and belt-based speed transmission. All operator interfaces are easy to use, allowing for quick workpiece changeovers and resulting in high output rates of crankshafts. The grinder is completely enclosed and features automatic front doors that provide easy access to the machining area.
