Good reasons to choose Walther Trowal

Our advantages

Free trials using your original workpieces before you invest

The process can be tested using your specific workpieces at our Test & Training Centre in Haan. This allows us to verify whether the desired surface quality and specifications can be achieved.

 

 

 

 

We deliver the optimum surface finish to meet your requirements

The grinding performance, shape and size of the abrasive media influence the resulting surface finish. At Walther Trowal, we manufacture a range of consumables and abrasive media with varying degrees of abrasiveness for this purpose. Drawing on our experience as the inventors of mass finishing, we can tailor the process to your workpiece, material and desired surface finish.

Step-by-step instructions for achieving your desired result

 

At the Test & Training Centre, your workpiece samples are assessed and machining concepts are developed specifically for you. In doing so, we also take into account specific requirements such as surface roughness, edge rounding or readiness for electroplating.
