Computer-Controlled Blasting.

Guyson has introduced its Model RSSA-8 rotary automatic blast machine, the first in a series with a multiple-axis PC-based motion controller providing integrated closed-loop servo motor performance for precision nozzle positioning. Developed for blasting applications that demand the greatest precision and repeatability, the motion control system makes the machine more flexible than the firm's PLC-driven models. The system is network-capable to enable programming, monitoring and data acquisition from a remote computer terminal. The gantry-style motion system allows extremely accurate motion control and positioning of one or more suction-blast or direct-pressure nozzles that is synchronized with controlled rotation or indexed movement of the product's rotary table. All servo motors and precision components are sealed and located outside the work enclosure for protection from the abrasive enviroment. Compatible with CAD/CAM programming packages for simplified motion program development and downloading of data on components to be blasted, the control system can store and recall processing parameters and coordinated motion routines for a range of parts, eliminating the need for set-up time or manual adjustment.
