Sherline ER-16 Headstock and Motor Unit 3308

Sherline ER-16 Headstock and Motor Unit 3308ER-16 Headstock and MotorThe 3308 would replace the standard headstock, motor and speed control assembly that come on Sherline machines. The ER-16 nut that ships with your order may be plain or have a black oxide finish.ER-16 Spindle AvailableNote that the headstock, DC motor and speed control can also be ordered with an ER-16 collet spindle nose. This would be in place of the standard Sherline #1 Morse internal taper and 3/4-16 thread on the nose for those who prefer to use ER-16 collets. Sherline does not supply the collets, but they are available through MSC Industrial Supply Co . and other tool suppliers. Keep in mind that if you order the ER-16 nose, no Sherline accessories that use a #1 Morse taper or 3/4-16 thread will work on this spindle.To power and control the motor, you will need a more sophisticated speed control unit. This unit accepts any incoming AC current from 100 VAC to 240 VAC, 50 or 60 Hz. It automatically outputs 90V DC to the motor. You can use this unit anywhere in the world without a transformer.SpeedAll you need is the correct wall plug or converter. Once switched to the ?ON? position, a speed control knob is used to vary the speed over the entire range. With the pulley in the ?normal? position, the speed range is about 70 to 2800 RPM. In the ?high torque? position the maximum speed is cut in half but torque at any given speed is much greater.This unit can be purchased to replace an existing AC/DC motor on an older Sherline machine, to turn a mill XYZ base into a complete mill so that you don?t have to swap power units back and forth from the lathe, or as a stand-alone unit for custom tooling designs. This very compact and well-engineered unit costs far less than other DC units of similar power offered in major industrial tool supply catalogs.
