CNC Machines, Spindles
September 26, 2013
Most of us first heard the term “horsepower” when we became interested in motor vehicles. As youngsters, the concept was pretty simple: More horsepower meant faster cars. That was before we learned about the other factors that affect automobile performance such as torque and RPM.
Electrical motors, including those used to drive CNC machine spindles, are also rated in horsepower and it’s sometimes difficult to evaluate the potential performance of a machine tool without falling into the “it’s all about horsepower” trap. In reality there are a number of factors to consider when evaluating the power, reliability and expected life of a CNC machine tool’s spindle motor. Here are a few:
Gosiger applications engineers can help you determine which CNC machine tools will provide the performance you require for your specific production demands. Okuma CNC machine motors, as an example, are designed to run cooler and to last the lifetime of the machine. They do not need to stop running to cool down, so they don’t waste valuable production time. The horsepower rating of these motors are defined as mechanical output, not simply power consumption. Okuma motors provide maximum torque at 50 RPM that is critical for low RPM machining. To learn more, contact Gosiger today.
