Third Party Workholding Options
With a 5-axis machine there are numerous ways to fixture your parts on the Pocket NC machines depending on your application. Pocket NC offers two workholding options which are discussed here, but in this post we’re going to share several other options created by Pocket NC customers. Because there are numerous ways to fixture your parts for multi-axis machining customers frequently inquire about alternative workholding options that are an ideal fit for their application. Some benefits of different workholding can include utilizing a larger work envelope or making your part(s) more efficiently.
