Namco has taken on two new apprentices.

This will ensure that these young persons will have the ability to produce high quality tooling.

A further trainee grinder, is now working on the thread grinding section, and is making excellent progress.

Two more apprentice engineers are planned to start soon and will receive a thorough basic training during this first year.
