Part two is about making the spindle axis perpendicular to the table …
↓↓↓ Complete description, time index and links below ↓↓↓

In a first step we’ve adjusted the head and z-axis ways of the Proxxon BFB 2000 mill/drill stand, to make the z-axis as perpendicular as possible to the table (link below). Now it’s time to do same with the spindle axis.

So we clamp the Proxxon BFW 40/E spindle into the stand, attach a dial gauge to the spindle collet using an adapter shaft (link below), and measure the tramming error. However, that error can only be corrected by shimming the spindle.

00:00 Intro – tramming the spindle axis
00:54 Remark – things will not go as planned
02:01 Shimming – the way to adjust the spindle
03:06 Runout – the enemy of tramming
05:38 Setup – tramming table and dial gauge
06:47 Measuring – the tramming error
12:25 Correcting – the tramming error by shimming
13:20 Verifying – the shimming reduced the error
16:30 Wrap-up – things went not as planned, bye
