Type keyword s to search. The universal carbide grade for railway re-turning is P15, which is recommended as the standard first choice for most conditions.

How Diesel Locomotives Work

Have you ever thought about how trains stay on the tracks when they round corners? Article Post: For most heavy freight wheels, inserts with high plastic-deformation resistance are needed for the heavy, deep cuts.

This not only adds years of life to the railway wheels, but has the added advantage of extended rail life. These flat spots are extremely hard and are difficult to machine. The downside of using steel wheels is that they don't have much traction.

Steel Wheels. The amount of energy used by the tires is proportional to the weight that is on them.

Re-Turning Adds Life to Train Wheels

The end result is a train that stays on the tracks. Cutting speed is determined by the type of grade being worked with and the wheel condition. Heavy locomotives, high-speed trains and metro trains tend to use these under-floor machining setups.

Also, flat spots can occur on the track-contacting wheel rim, particularly if the wheels locked up or began sliding across the rail when braking.

Since a train weighs thousands of times more than a car, the rolling resistance is a huge factor in determining how much force it takes to pull the train. Train wheels aren't perfect cylinders. The grade features technology that provides maximum tool life through a unique, unidirectional crystalline coating structure.

Chip control is particularly important in under-floor machines, as gravity pulls chips into the operator areas.

The Science of How Trains Turn Without Falling Off the Tracks

Grades P25 are typically used with a style R1 chipbreaker. Tires bend and deform a lot as they roll, which uses a lot of energy. Eastec 2019: How Diesel Locomotives Work.
