What I was saying above is that we have a real need to set this. Ceramics are very abrasive and they get into everything. Changing ballscrews is just about an every week thing. We go through sealkits for the through spindle coolant like they are water. In fact, we don't get a warranty on the mechanical parts of the machines because of the type of stuff we machine. We do no metal working at all. I would say that we change out ballscrews about once a year in each machine. After all, you can use a ceramic block to sharpen a knife. Then you add the diamond dust from the cooling... You get the picture. |
