07/21: Precision Right from the start

INTERVIEW WITH MASS FINISHING CONTRACTORS HENSEL & BLANK

Volker Hensel and his former employer experienced a real turning point back in 2003 when they started using OTEC’s CF disc finishing machine, which reduced their valve spring processing times by 96%. Volker and his business partner Horst Blank then opted for OTEC’s technology expertise when they founded their company four years later. Volker Hensel talks to us about what makes his company’s over 20-year partnership with OTEC so special from a per-sonal and business perspective.

07/21: STREAM FINISHING - the green alternative to chemically accelerated processes

Processes in comparison: Processing of highly loades gear wheels for aerospace

Many highly loaded steel gear wheels are produced for use in the aerospace industry that must be ground to an extremely high degree of precision and hardened to levels greater than 60 HRC. The surface of a gear wheel is solid and tough. If it is to function safely and reliably later on, the surface structure must be flaw-less and extremely isotropic, meaning it must be highly uniform in all directions. As well as requiring a roughness of below Ra 0,1 µm, the involute surface must not be wavy or show any grinding grooves. In addition, the edges on the sides and on the tooth head must be evenly rounded.
