[edit] Wells Index 20567
[edit] History
Serial number 20567 (1980) Serial number 20567 is a USA made mill and shipped without a model number in November 1979 to a company in Texas who installed the control on it for the 1980 IMTS show in Chicago. I am not positive but that is what I remember and see in the records. Parts are still available for the mechanical part of the machine.
[edit] Spindle
It shipped with 200KS spindle taper. Tooling is still available from Wells Index.
According to Wells Index:
200 KS stands for 200 Kwik Switch 200 Kwik Switch designed by Universal Engineering and it is not like any other. Other companies make tooling that will fit it and call it rapid switch or rapid change. It is about the same size as #30 NMTB or #30 MMT. Used and new tooling is available. The spindle taper is not grindable as it has to be a specific depth in relation to the nut that holds the tool in so you have to grind it deep and then build it back up with hard chrome and then grind it again to the correct depth. This is doable but the hard chrome starts flaking off after a while. We have tried this before and the results were not satisfactory. If the spindle taper is bad the spindle has to be replaced with a new spindle and the bearings also need to be replaced. If you do not have any tooling I would suggest replacing it with a # 30 taper spindle as this is a better spindle with tooling readily available from us and other companies. The #30 can also be touched up by ID grinding later in the machines life.
[edit] Moving this thing
Shipping weight for a CNC mill is 3700 lbs.
You need to remove the ball screw and table bracket on both ends and then the gib. . The ball screw can stay assembled with the left side table and motor bracket assembly. You can then slide the table out onto a cart
Height of the machine with the motor removed = 84 Inches
- Lower table and Center table left to right. Move as close to column as
possible. Center over arm in and out.
- Pick up by over arm with fork lift at front and back of column or use straps in
same locations - use wood to protect the way.
- Do not slide forks under base of mill as mill is top heavy and will fall over.
This is the most common mistake made.*
