Grinding programs for precision spindle shafts — 1.4μm runout achieved

The situation

A manufacturer of precision machine tool spindles was launching a new product line requiring CNC grinding programs for shaft profiles with a runout specification below 2μm. This level of precision in series grinding requires a programmer with direct experience in precision grinding processes — familiarity with wheel dressing cycles, thermal behaviour during grinding, and the relationship between cutting parameters and surface geometry. The client’s existing programming team did not have this background.

What GFE did

GFE provided a CNC specialist with a precision grinding background for a two-week on-site engagement at the client’s facility. The programs were developed directly on the production machines, with an iterative cycle of cutting, measurement, and parameter adjustment until the programs were stable and repeatable at the required accuracy level. The final programs, locked for series production, held an average runout of 1.4μm across the shaft profiles — below the 2μm specification. All programs were documented with the associated grinding parameters and setup conditions to allow the client’s team to maintain them in production.

Runout at 1.4 micron in series production. That is what we needed.

Why GFE for CNC programming

Programs are written and validated inside the client’s own CAM environment — using their software, file structure, and naming conventions. No separate system, no format conversion.

Each project is handled by programmers with direct experience on the relevant platform — Siemens NX, SolidCAM, Mastercam, or STUDER.

All programs are collision-checked and validated in Vericut before reaching the machine. This eliminates first-part scrap and reduces setup time on the shop floor.

All team members communicate in English. Senior programmers also speak German, enabling direct coordination with production and quality departments at client facilities in DACH.

Our customers

Our company produces safety-relevant welding assemblies for the chemical and pharmaceutical industry.

Due to the fact that it has become increasingly difficult to find good engineers and designers for our design department at our location in rural Münsterland, we set out at the end of 2018 to look for new external solutions in the service market.

 

Christian Menke

CEO V. KRANZ GmbH, Dülmen

I really appreciate GFE’s flexibility and openness for new challenges. They are not afraid to start a new journey.
If I think about the external circumstances of the project we started together, we reached a learning curve and relating results that I did personally not expect.

Daniel Ilge

Head of Technology & Product Management at WALDRICH COBURG GmbH

We required additional capacity and professional support for our R&D Team especially for a new product development.

And GFE Solutions offers capable support by very well-educated engineers. High professionalism. On time delivery and great communication (native German speakers).

Frank Pfister

CEO of CVS engineering GmbH

We are the company in constant need for plants for research or pilot projects of our clients. Last year we were working over the order in the field of medical technologies, which we succeeded to realize, including thanks to efforts of GFE Solutions team.

Dr. Thomas Bauer

Chief operating officer and member of the Board of DIENES Apparatebau GmbH

We were in need of help with our design department ressources and we had to move fast, internal ressources were not available and GFE was able to help quickly and competent. GFE works with dedication to the very needs of its customers, has a variety of specialists and has offered a fair price on a transparent basis.

Sebastian Schuelke

Managing Director at SICON GmbH

We were looking for additional engineers to expand our construction capacity. You seemed to be a young, motivated Team and except your professional expertise, your personal commitment made me confident to work with you. The cooperation has been seamless and very productive from the start. We are happy with the results.
