A CUSTOMER’S QUESTION

What do you mean by extreme precision?

 

 

REPLY FROM PROTOPAJA

Extreme precision is required when really thin materials and small-sized components are worked on, with tolerances measured in micrometres.

The thinnest material we can process is only 0.05 millimetres thick. It is half of a regular copy paper and a just little thinner than human hair.
