High-Torque Retention Knobs for CNC Milling Applications
J&M Machine will feature its High Strength series of high-torque retention knobs made from H-13 steel.
The Knob Problem
The retention knob is an unmistakably critical component of the machining process. However, the tightening of the knob itself can lead to the toolholder not seating securely in the machine. You may be losing tool life to knob tightness without even knowing it.
This footage illustrates how the toolholder taper is measured in a test designed to capture the retention knob’s effect on the shape of the toolholder taper.
