Proxxon FD150/E

Roger B:
Thank you all for the comments.

Jo, the wine is actually borrowed from my neighbours cellar to set the scale. So far I haven't had any electrical problems with my Proxxon machines.

Derek, I initially queried the accuracy with the supplier who arranged for it to be sent to the local Proxxon service centre for checking. They said it was within the specification. I than discussed the findings with Proxxon's technical department. They have seen all the video clips and pictures. Their view is that they have delivered an acceptable price/accuracy combination however they were going to check the design of the collet nut.

The lathe and accessories in the picture cost CHF 635.

Having reached a reasonable accuracy I then tried some cuts.

First I turned a piece of 3mm brass down to 0.7mm and spotted the end with a 0.5mm centre drill. I then drilled to full depth with a 0.2mm drill followed by a 0.5mm drill all without problems at 5000rpm. Next I took a 0.5mm cut in a piece of 5mm silver steel again without problems.

I then checked the alignment of the centres with a steel ruler clamped between then, not too bad  :)

Finally for it's first job I drilled the ends of some 4mm grub screw for the tappet adjusters on my twin cylinder engine.

Hi Roger, a very nice addition to your cellar paradise. I like it also very  much to have my Unimat SL at the shelf for special jobs.

Roger B:
The details are in another thread, but I finally got round to modifying Sherline 3 jaw sc and 4 jaw independent chucks to fit this lathe  :) :wine1:

Kim:
Looks like a nice little addition there Roger!

I have been looking at insert grooving/parting tools being prompted by some of the threads on here. They all seem to start at 8mm high holders which will not fit the FD150. Looking at the tool holder the base seems quite thick and could have 2mm milled away. The cutting forces on this lathe will never be very large.

The clamping screws are burred at the end and were not easy to remove so I left them in place. One side is left standard for 6mm tools.

As a trial I drilled and tapped a piece of 8mm silver steel M2 and then parted it off with a home ground parting tool. With a slow steady feed and lubrication with an old tooth brush no problems  :)

I now need to select some suitable insert tools but that will be the subject of another thread.
