Tolerances
This page summarizes the general production tolerance standards referenced by Laser Master for metal and non-metal parts. Small dimensional deviations can occur during manufacturing for mechanical reasons, and these allowable deviations are defined as tolerances. The achievable tolerance range depends on the processing method.
Please note: if you need to deviate from the general tolerances, you should leave a comment with the order. Processing time and price can then vary.
Laser Cutting Tolerances
Standard linear tolerances
Use BDS EN ISO 9013-1 for standard linear tolerances of laser-cut parts.
