Hands-on training for engineers, programmers, setup personnel and operators.

Technical milling training at Dapra's Midwest Tech Center

We believe that education of the process – not just on our product – is critical to our customers’ success. This is why we incorporate many practical examples in our training. We want class attendees to get a firsthand look and understanding of the process, in a safe environment where no parts are scrapped, and where help is readily available.

Attendees have repeatedly told us how much they appreciate this training, and how much more they learned by doing it with us versus simply watching a prearranged demo put on by the host company.

Mike Bitner – Vice President, Sales & Product Management

Technical milling training classes at our Training and R&D Center are focused exclusively on practical, usable machining principles – not on product marketing.

Classes at the Training and R&D Center provide a combination of both theoretical and practical training, with a 30-horsepower Haas VM-2 mold making machine tool on the classroom floor for hands-on demonstrations. This mold/die machine is well-suited for complex 3-dimensional surfacing, as well as typical 2D profiling and face milling. All training classes cover many practical examples to give attendees a thorough understanding of the process, providing immediate visual confirmation of the parameters and tooling chosen for the cut.

Attendees often tell us that the repetition involved in choosing the right tool and operating parameters, then doing the calculations for correct speeds and feeds, really helps to cement the concepts covered. Related processes and technologies such as workholding and spindle-mounted dot peen part marking can also be demonstrated.


What are our milling training goals?

  • Improve general milling applications knowledge base
  • Milling principles
  • Formulas
  • Tool selection and optimization, application-based
  • Troubleshooting
  • Improve working knowledge of Dapra products, including: cutter applications; carbide geometries and grades selection; workholding applications and capabilities
