OM651 2.1L 8 Panels Crankshaft OE 6510300401 For 220w S600

1) External milling of crankshaft main journal and connecting rod journal

When processing w220 crankshaft parts, due to the influence of the structure of the disc milling cutter itself, the cutting edge and the workpiece are always in intermittent contact and there is an impact. Therefore, the clearance link is controlled in the entire cutting system of the machine tool, which reduces the vibration caused by the movement clearance during the machining process, thereby improving the machining accuracy and the service life of the tool.

2) Grinding of crankshaft main journal and connecting rod journal

The tracking grinding method takes the center line of the main journal as the center of rotation, and completes the grinding of the crankshaft connecting rod journal in one clamping (it can also be used for main journal grinding). The grinding method of the connecting rod journal is controlled by CNC The feed of the grinding wheel and the rotary motion of the workpiece are linked by two axes to complete the feed of the crankshaft. The tracking grinding method adopts one clamping and completes the grinding process of crankshaft main journal and connecting rod journal sequentially on a CNC grinding machine, which can effectively reduce equipment costs, reduce processing costs, and improve processing accuracy and production efficiency.

3) Crankshaft main journal, connecting rod neck fillet rolling machine tool

The rolling machine was applied to improve the fatigue strength of the camshaft for Mercedes Benz s600. According to statistics, the crankshaft life of the ductile iron crankshaft after fillet rolling can be increased by 120% to 230%; the life of the forged steel crankshaft can be increased by 70% to 130% after fillet rolling. The rotational power of rolling comes from the rotation of the crankshaft, which drives the rollers in the rolling head to rotate, and the pressure of the rollers is implemented by the oil cylinder.
