Thread: Another Swiss Grinder

Hi BT,
Interesting machine indeed. Did you work out how the spindle is driven yet? or how the spindle height is adjusted?

The table feed is a great idea that seems like it would be easy to fit to lots of machines.

The spindle is mounted on a pivoting arm. It looks like the handwheel to control the spindle height, is behind the right hand end of the table. I imagine a drive belt runs up from the base to a pulley mounted on the pivot which in turn drives another pulley and belt to the spindle. I will ask Martin how it all works.

I searched for Dubied. There is a firm of the same name located in Couvet that has made knitting machines for a long time. Could well be the same firm that made the grinder..... further searching has revealed that there is a Dubied knitting machine in the Museum Victoria collection. The cast in name looks the same as that on the grinder.

All interesting stuff Stuart. I love it.

Hi BT,

The "dust collector" plumbing is a bit weird, I suppose that would connect to a vacuum system when not using coolant?

Just looking at the layout, I can imagine coolant spraying all over the place..

Interesting machine.

BT,
I wonder if it's primarily a T&C that can do a little surface grinding as the depth of cut would be a little "rough". Still what "rough" is depends on what you are trying to achieve.

Ray,
I wonder how often vacuum systems get used? most of the surface grinders I have used have had the nozzle but none of them were ever connected. Is coolant normally used grinding cast? (a possible excemption is a flywheel grinder, but I cant be sure).
It would be nice to use the vacuum when dressing the wheel, which I've always done dry. Could it be done wet?Would it make any differeance?
The wheel guard looks to be able to rotate, but I would have thought you'd have to put something vertical on the left side of the bed at least a little higher than the work surface or you'd be swimming in no time.

Well Bob and Stu, Phil gound my cast iron straight-edge/level for me and he used lots of coolant - to stop the wheel from loading up with dust and to prevent the level from heating up and moving. Interestingly, when we started, the level was bent (about 2 thou), so he stuck it to the chuck with double sided tape, as the magnetic chuck would have pulled it straight - only to return to the bent shape on release of course.
