Hi Guys,
Since you were so helpful with my first post on this forum I figured I would try again.
On one of our 32-60 Blanchard grinders, the operator has noticed that the machine is running hotter than what he is used to. It seems to be getting hot near the lower spindle bearing area. The highest temperature I saw was 167 F.
The operator also said he hears a different noise than he is used to. I really don't hear much, but he runs the machine five days a week, so I'm sure his ears are more in tune with his machine than mine.
We have checked to make sure that grease is getting to the bearing. We made sure the fan above the spindle motor was clear and functional. We made sure that there is no swarf build up between the Faceplate and the wheel guard.
I am thinking that the bearing may be on its way out, but I don't want to take any drastic measures unless I am sure that it is a bearing issue. The bearings are crazy expensive, but it is a busy machine that makes us money everyday.
If you guys have any other suggestion of things for me to check I would appreciate it, or if you think I'm on the right track with the bearings.
On the drawing it looks like the lower bearing can be changed without pulling the spindle. I imagine if one is going the other may not be far behind. It looks like you need to pull everything to change the upper bearing.
