Re: Hot bearings

Hi Pete Thanks for the link. I had already found that particular site, although I was put off by the lack of a definite manufacturer for that bearing. I think the banner just said 'FAG and other leading brands'. I've emailed them and they've indicated they will supply FAG or SKF bearings rather than...

Hot bearings

Hi I've been using my new Novamill for the children's school project ( engraving brass key rings). It's been running flat out for a couple of hours , but the spindle bearings have got so hot I could barely touch the casting. Most of the grease has migrated south and now the bearings sound less than ...

Novamill capabilities

Hi I'm thinking of buying a Novamill for model engineering , building7.25" steam locomotives. Typically I'll be working with mild steel, cast iron and brass. Assuming the workpiece will fit on the table, is a Novamill capable of machining these materials or am I expecting too much from a machine of ...

Re: Failed triac motor speed control

Sorry, forgot to say, the chap selling the machine tells me the spindle runs at approximately 500 RPM. Does this help to narrow down the likely problem ?

Thanks

Re: Failed triac motor speed control

The machine is described as "Fully enclosed and with a 6 station
tool changer,and Fanuc or Heidenhain simulated interchangeable
controls."

Does this help to identify which type of drives its likely to have ?

Thanks

Failed triac motor speed control

Hi

I have my eye on a Triac mill from around 1994. The spindle speed control doesn't work, so the spindle only runs very slowly.

In the worst case, how much is it likely to cost to fix ?
Are there any common motor speed control failures ?

Sorry if this is a bit vague.

Thanks

Denford TRIAC programming from cad drawing

Before I begin, please accept my apologies in advance for what may seem like a completely stupid question ! I am considering buying a TRIAC mill, believed to be from around 1994. I don't have a serial number, but I do know the machine is fully enclosed and with a 6 station tool changer and supports ...
