Best Answer

The hollow spindle of a lathe allows for longer lengths of material to be held in the chuck thus eliminating constant material changing to and from the lathe in production turning. The best advantage is the saving in material costs. If one had to manufacture 20 bushings and they were all cut into separate billets, half of the material would be lost because the chuck needs some material to grip the work piece on.

If for example 20 bushings of 50mm OD by 50mm long have to be made, one would need a piece of material of at least 1150mm long. A single shaft or hollow bar of this length can usually be stuck into the hollow spindle with only enough material sticking out to make one or two bushings at a time. Once they are parted off, the material can simply be pulled out and the next one or two bushings can be machined. In the end the wastage will only be a piece of material of 70mm long instead of 20 pieces of 40 or 50mm long without a hollow spindle.

What does a knock out bar for a mini lathe do?

The headstock of a lathe is pushed into a tapered hole in the head spindle. It gets stuck in there in normal use, and you cannot pull it out when you want to change it. So . . . the spindle is hollow all the way through the lathe head. To get the headstock to lossen you insert a round knock-out bar into the front of the spindle until it touches the back of the headstock. A few taps with a mallet will jar the headstock loose. Then you remove the knock-out bar.

What do you mean by spindle in lathe machine?

The spindle of a lathe is a rotating hollow tube within, and protruding the head stock and to which a chuck, drive plate or facing plate attaches and rotates to enable machining. It is housed within the head stock in bearings and has some gears around it which is driven by other gears which in turn is driven by an electrical motor.

What two factors are used to determine the size of a lathe?

The two factors that determine the size of a lathe are the "swing" and "distance between centers". The swing of a lathe is the length measured from the center of the hollow spindle or chuck to the nearest part of the bed multiplied by two. Distance between centers is the distance measured between the chuck and tail stock.

Why the bed of the lathe machine is hollow?

The bed ways of a lathe in itself are not hollow, but the area between the ways are. This is primarily to reduce the weight of the machine and also the cost due to much less material used to manufacture it.
