Cotta Tech Talk – Hard Turning

Hard Turning: Did you know?

Cotta has increased the use of hard turning, as an alternative to precision grinding, for achieving dimensional tolerances and surface finishes, faster. Hard turning is very efficient for cylindrical shaped parts such as gears, shafts, and pinions. While precision grinding provides the ability to achieve higher dimensional tolerances, we can often reduce setup and machining time through hard turning. This process can also be more environmentally friendly because the metal chips leftover from hard turning can be recycled, versus the disposal involved with the swarf generated by grinding. Cotta takes great pride in our manufacturing, and this process improvement isn’t too “Hard”.
