Guyson Corp. has introduced a pressure-blast version of its Model T-50 tumble-blast system that offers advantages for certain challenging batch processing applications. The tumble-basket machine is designed for overall blasting of small components.
Direct pressure media delivery is capable of efficiently accelerating shot or grit to higher velocities, imparting more energy to component surfaces. Not only does pressure-blast speed up the cycle time per batch, but it enables the performance of some surface treatment work that could not be accomplished by suction-blast equipment, such as high-intensity shot peening of racing valve springs, peening other high performance springs or small parts, stripping of tough coatings, blast cleaning heavy scale and etching hard materials.
The T-50 tumble-blast cabinet features a 30-inch diameter basket that is 15 inches deep and has a working capacity of approximately one cubic foot or 75 lb of components per batch. The rotation speed of the basket is adjustable, so the tumbling action of different components can be optimized.
The equipment manufacturer claims its tilted basket design reduces part-on-part impingement that could damage fragile components and generates better circulation of parts in the batch, yielding more thorough coverage, greater uniformity of finish and significantly shorter blast cycle times compared to barrel or endless belt tumble-blast equipment.
Prospective users of tumble-blast finishing or shot peening equipment are invited to submit sample components for free laboratory testing and application engineering evaluation at the machine builder's factory in northeastern New York State
