Vibratory Bowls – Vibratory Finishing Machines
Smooth, consistent finishes for many parts at a time – for cleaning, deburring and polishing products that must meet specific quality standards.
The machine
What is a vibratory finishing machine?
Vibratory finishing machines are usually spring-mounted open-top containers attached to an oscillation or vibration generator. Vibrations are induced by an excenter (a shaft with an offset mass connected to an electric motor).
Parts are placed into the open-top container, which already includes free abrasives (chips) and chemical compounds (or water). Finishing operations occur at vibrational frequencies of 15–50 Hz. The finishing rate can be accelerated by increasing the vibrational frequency. Water may be used instead of chemical compounds to reduce the material removal rate (MRR), which is necessary for achieving a fine surface roughness.
The process
What is the vibratory finishing process?
Vibratory finishing is a type of finishing that involves a bowl or tub. This process is unique because it requires you to place a large volume of parts into the bowl and let the parts vibrate inside it. The vibratory function causes friction, making the pieces rub against an abrasive medium until they lose their rough edges and achieve the desired texture.
Vibratory finishing machines are designed to create smooth, consistent finishes for multiple parts and products at a time. They’re useful for cleaning, deburring and polishing products that must meet specific quality standards. Depending on the project, you may choose to use either wet or dry vibratory finishing. The wet process requires the use of water, which can often be treated and recycled for other applications.
