LR010297 NEW Crankshaft for Land Rover Discovery 3 and Range Rover L405 3.0 TDV6

1. CNC internal milling cannot process undercut grooves on journals; CNC high-speed external milling cannot process axial undercut grooves, but turning (including turning-turning) can process.

2. When the journal of rance Rover Genuine Crankshaft has no undercut groove, several processes can be processed.

3. When the side of the balance weight of the crankshaft does not need to be processed, the machining cycle time of CNC turning (including turning-turning) is almost the same as that of CNC internal milling.

4. When the side of the balance weight of the crankshaft is to be processed, the processing cycle time of CNC internal milling is much better than that of CNC turning (including turning-turning).

5. When the side of the balance weight of Land Rover discovery 3 crankshaft is to be processed, the process of turning (including turning-turning) is adopted. Since the side of the balance weight is processed intermittently, and the crankshaft speed is very high (about 1000r/ min), the knife-cutting phenomenon is relatively serious, and it is unreasonable to use the turning process to process the side of the crankshaft balance weight.
