 The top spindle is Towpell's special # 40 taper. There are 3 sets of high precision P4 bearings at the bottom and a single bearing at the top. This gives extra rigidity and vibration resistance. We normally set these up to use Cat-V-40 tools. For comparison, below it is a standard spindle in a Bridgeport type R-8 spindle at the bottom with only 2 high precision bearings at the bottom. |
