For many years, I was the proud owner of an AP lathe (AP being the
initials of its maker, Antoni Pujantell). This lathe was the very
first machine tool I brought home, and after many years of loyal
service, I sold it a few days ago.
This entry describes the Cincinnati-Chomienne model FP30 milling
machine. It has served me well for a number of years, but it is now up
for sale. Literature on this machine is scarce; I have only managed to
find manuals for similar Cincinnati-Chomienne models and a brochure
that details its main dimensions.
Some time ago I bougth an Isoma centering microscope with ans SK40 adaptor. However I have no SK40 machine at all. During the last days I have been turning a cylindric tail which let me to use the microscope in the lathe as well as in the milling machine.
The part was dimensioned from an original one. It is a M15x0.75 threaded end with two main features:
A 16mm bushing guide that assures concentricity, and A mating ring that assures perpendicularity.
One of the jobs done this summer is a special square intended to facilitate the alignment of the grinder axis. I own a Klaiber WSII tool grinder. This grinder has a head with several degrees of freedom and aligning it to the table is not easy given the poor quality of the head scales. Thus, I decided to build a particular square that fits in the head nose and offers a reference plane to test with the indicator or the protractor, for instance.
The tailstock Some time ago I bought an old series Boley Leinen lever tailstock to be fitted to my lathe. This is the tailstock:
It is of the old type because it uses a split casting to lock the barrel as you can see in the picture. Leinen buid two flavors of this tailstock: one with a barrel that takes 363E collets (the 25mm collets) and other that takes the 323E collets (15mm collets).
This post is the result of analysing the lubrication requirements,
data in the machine manual and availability of oils and greases. It
recommends how to lubricate the Boley Leinen LZ4SB. Surely, it could
be used for other Leinen lathes close enough to this.
Some months ago I bought an old Boley-Leinen collet closer. The gadget is almost complete but:
It lacks the supporting bars The ball plungers were broken The collet closer levers were broken The cosmetic was not at its best The collet closer as bought The following picture shows the collet closer assembled as usual:
Below, you can see some details of the parts. In the first picture, you can see the closer body.
Which are the collets that uses the Klaiber WS2 tool grinder? I found the answer few days ago while looking at ebay.de. A seller was offering a Klaiber grinder.In the machine pictures there was this one:
It is a 6mm collet for the klaiber. The picture has the answer!! Klaiber collets are of type 317E. It was a non usual collet size. I have not found any provider offering it. If somebody knows the nominal dimensions for this standard, I will be happy to hear about it ;-).
