Vibratory finishing machines, also known as trowalizers or trowal machines, are machines used for surface finishing of metal and plastic parts. These machines are usually widely used in the manufacturing industry and are used for a variety of applications, including deburring, smoothing, polishing, cleaning, degreasing and coating parts. The operation of vibratory finishing equipment is based on the principle of vibratory finishing. In this process, the parts to be processed are placed in a rotating drum or container together with abrasives and an abrasive medium (often water and cleaning agent). The rotation of the drum sets the abrasives and the abrasive medium in motion, causing the parts to be machined against each other by the relaive motion of the abrasives and the abrasive medium. The type and size of the abrasive media and the abrasive media can vary depending on the application to achieve different effects on the parts being machined. For example, larger and harder abrasives are often used for deburring, while smaller and softer abrasives are preferred for polishing. The advantages of vibratory finishing systems are that they can process large numbers of parts in a short time and with a high degree of precision. In addition, they can also help extend the life of tools and machines by improving the surface treatment of parts.
