The Drag Finishing Technique developed by Walther Trowal is a special process for mass finishing of high value and delicate components and is most commonly used for grinding or radiusing. Walther Trowal Drag Finishing machines are also an excellent choice for those parts that feature sophisticated geometries or countours making them difficult to machine with other solutions.
One specific application that is perfect for this machine, for example, is the super finishing of car wheels. The drag finisher provides a high shine, almost chrome-like finish.
