Graf GmbH
Our Technology
Production and quality control
Requirements
The quality of a die can be seen from its blank using only German steel. We have strict requirements for the material specification
of the blank, the drilling and hardening processes and also for the final inspection.
Machinery
Our machinery has been carefully selected and further developed in-house. The CNC lathes are modified to suit our needs and our gun drilling machines, with which we have most experience, guarantee precision and consistency of hole bore quality. Following the vacuum hardening process, dies undergo a final machining process in accordance with your requirements.
Production
All stages of our production are coordinated with one another.
Dies are inspected after each process; this is how we attain
our “Made in Germany” stamp of quality.
