Anyone try grinding UHMW - Practical Machinist

The CTE (coefficient of thermal expansion) for UHMW-PE is 120 µin/in-°F. In other words, a 1" thick piece of UHMW will grow 120µin (0.000120") for every degree (F) increase. If you machine it dead on and the temperature changes 5 degrees one way or the other, it will be out of tolerance. (That's assuming it's 1" thick.
