At CNC-Tool we provide top quality Tightening Stands for CNC Tool Holders. We offer Top Mount Tightening Stands, Side Mount Tightening Stands for HSK, ISO, SK, and BT Tool Holders. We recommend using a tightening fixture and torque wrench to make sure cutting tools and retention knobs are properly tightened. Over-tightening can distort or even crack collets, causing run-out problems and premature failure of the collet, nut, tool holder and cutting tool. Under-tightening can also cause poor cutting performance, or allow cutting tools to fly out of the spindle – a very serious safety hazard. |
