Tolerances for steel processing
Each metalworking technique has a 'bandwidth' of tolerances. These tolerances are set out in standards. Cutting carried out by De Boer Snijbedrijf meets the requirements of NEN-EN-ISO 9013. This international standard applies to oxy-fuel cutting from 3 mm - 300 mm, plasma cutting from 1 mm - 150 mm and laser cutting from 0.5 mm - 40 mm.
