Rounded edges, reliable processes, less wear: mass finishing is a winner for Wunschmann precision tools
In drag finishing (or mass finishing), parts – in Wunschmann’s case milling tools for metal cutting – are pulled through a bulk container. The material abrasion is clearly specified beforehand: debur-ring/rounding or smoothing/polishing. This optimises the tool’s surface and improves its functional properties. more...

04/20: Stay up and running: tablet Tools with flawless surfaces
Automatic polishing saves time and money
A smooth pressing surface reduces friction between the punch and the powder, often increasing production rates as a result. It also reduces the tendency for tablets to stick, and therefore quite literally guarantees smoother processing. Polishing can significantly extend tool life as well as reducing the cost of replacement dies and machine downtime..

Why custom processes for edge rounding on carbide tools are vital
Edge rounding (honing) on carbide tools is an established process that extends tool life and im-proves PVD coating adhesion. Rounding and smoothing the cutting edges minimises the risk of mi-crobreakage and significantly increases their mechanical stability. That’s the objective. Clear and simple.

BOOSTING EFFICIENCY: OTEC MEETS THE DEMANDING REQUIREMENTS OF AIRCRAFT CONTROL TECHNOLOGY
Precision deburring and smoothing of roughness peaks along with defined edge rounding on bushings and spools not only reduces friction in the valve but also increases its contact ratio. High-precision processing also enables the closest possible tolerances – a critical factor in system tightness. It also permits a higher switching or stroke frequency, significantly increasing control accuracy.
03/20: Automotive: Targeted Surface processing has measurable benefits
No doubt you’ve seen in the press that the EU plans to introduce automotive industry fines this year. Manufacturers will have to pay Brussels €95 for every newly licensed combustion engine vehicle that exceeds the CO2 threshold of 95 g/km. According to the Council on Clean Transportation, aver-age emissions in 2018 were 121 g/km.
Florian Reinle, an R&D engineer at mechanical engineering company OTEC Präzisionsfinish, high-lights how vehicle manufacturers can optimise their production processes and reduce friction at the same time.
