The features of spring spindle
Spring type spindle usually appears in NSK products. Most of people are afraid of this because of the 2.2 – 2.4 kgf lower initial gripping force. However,it is actually better for the safety and durability.While you push the bur like dentists drilling the teeth, the spindle holds harder and the gripping force will rise to 3 – 4 kgf.At this point,flying bur events are impossible to happen.
Before we try to replace anything, we usually take a look at the specification and want to know if it may cause any side-effect. It applies to replacing spindle as well! The main features of spring spindle are
1. two steps retention force
2. when the spindle breaks eventually, most of the time the bur sticks in the spindle
So, basically if your customers can accept the above features, then spring spindle cost you less in the same warranty situation.
