The machine shown has almost all the options added.
We begin the rebuild by completely stripping down the whole machine to its component parts.
Note: All bearings in the head and quill are replaced as standard with NSK or SFK bearings, this includes the spindle (Super precision) and Knee bearings.
All parts are inspected and anything with unacceptable wear is always replaced,
On all rebuilt machines with reground beds we always replace the XYZ axis leadcsrews with brand new and the double nut systems in XY axis plus the single standard nut system on the Z axis.
All belts are replaced as standard in the heads.
Variable speed and Belt drive head
We strip and rebuild both types of heads replacing all the bearings including the motor bearings and all the belts are replaced as standard. The variable speed head in particular takes a lot of parts during the rebuild process. We only know once we strip the head, which addition parts need replacement such as pulleys or the motor rotor. The parts bill on the variable speed can be in the thousands.
The quill is stripped and the bearings replaced in the spindle with NSK super precision bearings and the top spindle bearing is an SKF. The Spindle is sent away for the regrind of the R8 taper – during that time, the quill housing has the old paint removed smoothed sanded and re painted. Once the spindle returns, we rebuild the quill ensuring the feed mechanism works as per a new machine replacing parts where needed.
The re-grinding process is carried out by the best slideway regrind company in the UK and they regrind the XY saddle the top of the knee and then the table. The table gets the bottom done first, then to ensure it is still square the top of the table and the 2 side are also reground. All the gibs are then turcited and scraped back in. The column and back if the knee is also reground and the Z axis gib re-turcited and scraped back in.
Once all the parts have been stripped we remove the old paint and fill and sand then paint every piece individually with original Bridgeport colour Blue/grey enamel paint. We use enamel to ensure it is very hard wearing and so will look good for years to come. The painting process takes at least 2 weeks.
During the rebuild process we keep as close as possible to the original Bridgeport specification .
For example if the lube system has been changed for the newer and not better black pipe, which has a much smaller bore, we remove this and put back the original clear pipe with a bigger bore. The clear pipe also allows you to see the lube flow. This will reduce wear and ensure your investment will stay accurate and productive for years to come. When we purchase a new Z axis leadscrew it doesn't come with the original oil ports so we will re drill the deep oil port. This ensures good oil flow to your new Z axis leadscrew and Nut and thus ensuring good longevity of the machine.
