Mass finishing technology

Using the perfect combination of machine, abrasive media and compounds, we can attune the mass finishing process to ensure that your workpieces have the surface you require.

Mass finishing, also known as trowalizing, is based on processes in nature. Here, sand and water grind down rough blocks of stone to smooth, perfectly rounded pebbles. What we do in modern manufacturing technology is no different. With the right combination of machine, abrasive media, compound and water, we can perfect virtually every surface precisely to your requirements, using processes ranging from mass finishing, deburring, polishing and descaling to cleaning, smoothing and rounding.

Vibratory Bowls

From deburring and rounding to high-gloss polishing, vibratory bowls can be used everywhere in the mass finishing industry. These bowls can come as stand alone machines or can be part of an automated production process.

Centrifugal Disc Finishing units

Centrifugal disc finishing units have an abrasive action that is ten times stronger than that of vibratory bowls. This helps remove heavy burrs and round off edges on small and medium work pieces.

Inline Thru-Feed Vibratory Tubs

Our inline thru-feed vibratory tubs can be installed to continuously process your work pieces in the production process. The individual parts are added to the mass finishing machine in cycles, without interrupting the process.

Vibratory Tubs

If your work pieces are too large for circular vibratory bowls, simply process them individually in the vibratory tub. Sensitive parts can be secured or processed in separate chambers. Great for all types of mass finishing solutions.

Process Water Technology

Our process water technology is effective and efficient. Reusing process water (mixture of water and compound) and feeding it back into circulation during mass finishing can help you both save costs and protect the environment.

Accessories

Our wide range of accessories can help you adjust vibratory bowls, vibratory tubs, inline machines and all other processing systems to your individual requirements. Walther Trowal offers the accessories to improve your processes.

Media and Compounds

The right combination of process media and compounds can ensure perfect processing results. Ideal surfaces can be created with our ceramic or plastic abrasive media combined with compounds that suit your needs. We can find the exact combination of media and compounds to meet your needs!

Drums and Rotating Barrels

Drums and rotating barrels are the cost-effective solution for processing small parts, such as those in precision mechanics. These machines work best with small and medium batch sizes and are suitable for fine finishing and polishing.

Dryers

After mass finishing, parts are generally wet or moist and must be dried using one of our dryers. This is done using either a heated drying medium or hot air, depending on your individual needs.

Drag finishers

Drag finishing is great for high-value, delicate work pieces with complex shapes. Drag finishing is also great for work pieces made from tough, difficult to machine materials. They are mounted to special fixtures and dragged through a stationary bed of grinding or polishing media. Since the work pieces never touch each other during the process, they cannot scratch or nick each other.
