204 Heavy Duty Combination Brake Lathe
OPERATION
SPEEDS
1. Spindle speeds are 60, 100, and 170 RPM. To change RPM loosen thumb screw
(Figure 4 A & B). To remove belt guard (machine must be off) loosen wing nut
(Figure 4C), lift motor to free belt and put belt in proper groove. Replace motor and
tighten with medium tension on belt, replace belt guard. A larger diameter drum or
rotor requires a lower RPM. For most applications, Van Norman recommends the
middle pulley groove for passenger cars and light truck brake drums and rotors. The
outer pulley groove is for extremely small rotors and drums and the inner pulley
groove for very large drums and rotors.

FEED SLIDE
1. Feeds per revolution are 0 to .020". Feed per revolution should be as high as
possible for most profitable operation. Drums require a good finish. A setting of
.020" is used for rough cuts.
2. A large diameter drum or rotor requires a higher feed.
3. To change speeds loosen knob (Figure 5A) and move handle (Figure 5B), to desired
speed and lock knob.
