Toolshop

As a department of Pronar Sp.z o.o., the Tool Shop – TN was set up in 1996. The first operation was the production of instrumentation for the needs of the Disk Wheels Department – WKT (Pol. Wydział Kół Tarczowych), which was being established then and which started its operations in 1997.

As the production capacities of WKT grew quickly, the Tool Shop obtained new machine tools, which enabled us to introduce new technologies for the manufacturing of instrumentation and complete process lines.

The subsequent years of Pronar’s development – new departments and facilities involved the growth of TN.

Today we may boast state-of-the-art tools and machine tools and a specialised staff of engineers who lead a team of experienced employees.

We work in the SAP environment and use Solid Edge, AutoCad Mechanical and Mastercam software.

Please, see our range for more details and you are welcome to cooperate with us.
