INNOVATION

Especially for the aircraft industry (OEM/MRO), Walther Trowal has developed a wealth of processes and solutions in the field of surface finishing. From corrosion protection coatings to deburring and surface polishing, we offer the proper and suited process to finish:

• Landing gear / motor parts
• Structural parts
• Hydraulic /pneumatic components
• Brackets
• Gears

These processes are specifically adapted to customer requirements and components. The surface finish is important because surface smoothness and blending of machine marks and sharp corners improves engine performance, fuel consumption and safety. The surface finishing of casings and large structures on both new and re-built aero engines and air frames has always been expensive when is performed manually, which require a high skill level. Unfortunately, this method produces variations in finish resulting in quality problems. Throughout the aerospace industry, there are many types of Walther Trowal vibratory machines in use for finishing of large/long structures.

Walther Trowal manufactures specialised range of circular vibratory bowls without a centre column. These machines are used to surface finish blisks and disks (complete stator rings). New MV Vibratory (patent pending) model produce unique media movement, which significantly reduce cycle time in polishing or deburring processes. Walther Trowal circular/rotary vibratory machine line includes drying systems and waste water treatment systems.
