My Hyundai QT15N which is a mazak license copy has the T32B control, Its an old machine i know, think it is 1999 but its been ok since ive owned it, no issues or problems, no flat battery or memory loss etc but this last 2 weeks it has started to produce inconsistent diameters?
Normally il turn a part and then adjust the tool ofset until the dia is correct but now it seems to have different size errors on different diametrs all on the same feature using the same tool?
Say for example i turn a part with a 10mm od a 20mm od and a 30mm od the first may be under 0.4mm the second will be good and the third will be oversize by 0.7mm
The machine has not been crashed or bumped to cause this sudden inconsistency so i am stumped and have no idea how to try and fix it? yes i can lie about the part dimensions to dial it in but thats not what i want to do everytime i make a part, i don't use it everyday just as and when i need it so dont have the money to buy anything newer to replace it
Any ideas?
Thanks
Marc
