· Stopping and starting the mass of the motor and spindle: Since everything in a large machine is larger and weighs more, it takes more energy to get it going, and then stopping it. Not only does it take more power, but in most cases it also takes much longer. Longer cycle times also converts into more expensive machining costs.

· Working too hard to turn small parts at higher RPM: Since larger machines are working harder to turn the heavier spindle, more massive spindle bearings, and drive belts, it takes more power to keep the spindle running at higher speeds. 3500 rpm is simple for the OmniTurn. A machine with a 6" chuck running at the same 3500 rpm is really working hard.

· In warm weather it gets even worse. When you run a large machine it consumes energy and generates it back into the shop as heat. Just imagine a 100w bulb. Think about how much heat it gives off. Now think about a large lathe generating over 8000watts. If you are in a cold climate this is a great source of heat! If you have to rely on air conditioning, now you have to pay to get rid of the excess energy!

If you do the math on how much extra you are paying to run a large machine for small parts you would be amazed. Below is an example using rough numbers on a 10HP lathe vs the OmniTurn HE model, both with a part being run at 3500rpm, 30 second cycle, no spindle reverses (reversing would make the case for OmniTurn HE even stronger).

Older OmniTurns can be converted to High Efficiency systems for minimal cost. If your power is expensive, give us a call
