POK Rod

POK rod serves small-batch, non-standard and fast-delivery requirements. Typical uses include bushings, rollers, guide wheels and machined parts that need wear and hydrolysis resistance.

When turning, use a higher cutting speed and a smaller feed with coolant to control temperature rise; ream after drilling to hold fit accuracy. Because POK has slightly more spring-back than POM, interference-fit tolerances should be opened up a little.
