Tools and maintenance

All tools for the production are manufactured at Norma by Norma’s own toolmakers and all tools are inspected according to fi xed routines. We  measure all production tools with a measuring device that has an accuracy of up 1/10000 mm, and which in turn is regularly calibrated. In Norma’s production there are much as 2517 measuring instruments used – all are inspected and calibrated at fi xed intervals.
