I use to do a lot of close work for Hurco at one time (3yrs). They do not have a thermal expansion compensation program. They do not have liquid cool heads, ball screws, tables or guides. Every time you change speeds and feeds it is going to change due to the heat. It was probably ordered without glass scales this would help some of the problem. The head is putting off most of the problem and at 8000 rpm you are at the top of the problem. Who was the sales man and what teritory are you in. Maybe I can help if you were sold more that you got. |
