Okuma LT200MT Thermal Growth
Okuma LT200MT Thermal Growth
(OP)
We have a new LT200MY and are seeing huge amounts of thermal growth in the ZB axis. In a no load condition we have recorded up to .0065” in just over 2 hours. We have located one other shop with this same problem that saw almost 2 times this amount of growth and was wondering how many others are out there.
Thanks

Also contact an attorney about returning the machine as a defective design, not meeting the advertised tolerance specifications.
We had a new VMC that did not have the advertised spindle power, and until the attorney got involved, the dealer and manufacture would not do anything. After a couple of weeks the dealer paid us for our troubles and came and picked up the machine.
