What is the advantage of 3 jaw chuck?
3-jaw chucks are also better suited for machining longer workpieces because the longer collet chuck limits Z-axis travel. Spindle performance: Because they are lighter in weight, collet chucks have less mass, so the lathe spindle gets up to speed faster and puts less strain on the spindle motor.
What is the demerit of 3 jaw chuck?
