Bearings replacing and ball screws preloading during milling machines refurbishing process

Having bearings and ball screws in excellent conditions in a CNC milling machine, become essential for achieving a clean and vibration-free shaft movement in the axes. These elements allow axes displacement with friction-less than for sliding movement and, therefore, with low friction losses.

Ball screw rotates, thanks to an engine, transforming its rotational movement into linear movement on the axes. Bearings are located at the ends of the spindle for supporting them as well as for making their movement possible.

The importance of CNC programming in milling machines

At the end of the 60´s, computerized numerical control and its CNC programming was introduced in the industrial machinery, which allowed programmable automation of production and achievement of impossible movements to be done manually. This resulted in a significant increase in productivity, accuracy, safety, speed, repeatability and flexibility, together also with a reduction in waste in the manufacturing industry.
