When it comes to dialing in an ER system’s performance to match a specific application’s requirements or long life, there are three components to consider: the collet, the body of the holder and the nut.
The medical industry pushes the limits of precision for machining and tools. The trend toward less-invasive surgery using smaller parts translates to a need to better control the precision and tolerances of micromachining processes.
Cleanliness is key to achieving good runout control when assembling tool holders. Small particles or oil in a tool holder can cause large runout of the cutting tool, deceasing tool life and performance.
While we specialize in holders, we do offer some specialized cutters with these materials and often get questions about PCD and CBN inserts. Here we tackle some of the most frequently asked questions.
