What may happen if the wrong lever is moved on an off-car brake lathe during rotor machining?

A. Excessive lateral runout will warp the rotor and bend the lathe arbor shaft.
B. The lathe will rotate backward, causing the rotor to be machined backward.
C. The lathe will flash a warning light and a buzzer will sound.
D. The lathe will feed in the wrong direction, cutting a deep groove in the rotor surface.

Moving the wrong lever on an off-car brake lathe can lead to the lathe feeding in the wrong direction, which will cut deep grooves into the rotor surface. Such mistakes not only damage the rotor but also can affect the lathe's operation. Ensuring careful operation is crucial for the integrity of both components.

Explanation:

Effects of Moving the Wrong Lever on an Off-Car Brake Lathe

Using an off-car brake lathe for rotor machining requires precision and attention to detail. If the wrong lever is moved during operation, several issues can arise. The most critical scenario is that the lathe may feed in the wrong direction, which could potentially result in cutting a deep groove in the rotor surface, rendering it unusable.

This unintended action not only damages the rotor but may also affect the overall machining process. Other potential issues include excessive lateral runout that could warp the rotor or damage the lathe itself, as well as the possibility of the lathe operating incorrectly, such as rotating backward.

Conclusion

It is essential to ensure proper lever operation on the lathe to maintain the integrity of both the rotor and the machining equipment.
