Avoid costly repairs to machine spindles
Many factors can contribute to a spindle failing, but the leading cause is from contamination, such as chips or condensation. The humid atmosphere created in many machines, especially closed-type ones, further contributes to contamination. When the spindle is operating, its temperature is hot, and when the spindle is stopped it begins to cool, causing a…
Selecting the right motion component for CNC motion
Most CNC machines are built with high quality components, especially spindles. However, not every motion on a CNC machine is mission critical. CNCs have one or more axes that do not require high degrees of accuracy and precision. These axes can include doors and other auxiliary systems not associated with cutting. By picking an appropriate…
