Blasting Machine cleans, finishes, and prepares surfaces.
December 10, 2004 - Rotary indexing blast system, Model RX-400, features 30 x 36 in. blast cabinet and large side door for inspection, adjustment, and maintenance. Hinged doors actuated by pneumatic cylinders seal front of cabinet at load/unload station to prevent escape of blast media. Inside chamber, multiple blast guns are mounted on gearmotor-powered oscillator. Stroke and frequency of sweeping nozzle motion is adjustable, as are stroke count and duration of blast cycle and blow-off.

Indexing Gritblast System
November 30, 2004 - Saratoga Springs, NY - Guyson Corporation has introduced a new design in its series of automated blasting machines for work cell cleaning, finishing and surface preparation. The Model RX-400 is the most compact standard rotary indexing blast system yet offered by the equipment manufacturer.
The blast cabinet is 30 inches wide and 36 inches deep, with a large side door to provide access to the finishing enclosure for inspection, adjustment and maintenance. Hinged doors actuated by pneumatic cylinders seal the front of the cabinet at the load/unload station to keep operating noise levels low and to prevent the escape of dust or blast media into the workplace environment.
In operation, one or two components are placed in custom-designed fixtures on the rotary table of the RX-400. The system's precision cam indexer ensures that the 180-degree motion of the table is accurate enough to be fully compatible with a tending robot or automatic pick-and-place loading device. Inside the blast chamber, multiple blast guns are mounted on a gearmotor-powered oscillator. The stroke and frequency of the sweeping nozzle motion is adjustable, as are the stroke count and duration of the blast cycle and blow-off. If the machine is being loaded by hand, the attendant must touch two thumb switches to initiate indexing and start the automatic blast cycle.
Alternatively, if more complex motion routines are required for automated treatment of various components, the machine can be supplied with programmable linear traversing blast guns or a multiple-axis nozzle manipulator. The manufacturer advises that many selective blasting applications, such as deburring or deflashing of small components, can be performed with one or more guns bracketed in fixed position, eliminating the need for nozzle motion.
When hard, fast-cutting grit is to be used in the RX-400 for applications such as descaling, etching and surface preparation, special features are incorporated in the system to protect against the abrasive action of the media. The entire blast cabinet has a bonded rubber lining, as does the cyclone separator. Heavy cast urethane ducting can be used to return abrasive grit to the media reclaimer. Bronze gun bodies and boron carbide-lined nozzles are fed by urethane media hoses.
The control panel of the automated gritblasting system is streamlined by the replacement of numerous switches, buttons and indicators with a single touch-screen interface. Not only does this simplify operation of the machine and reduce the opportunities for human error, but the reliable touch-screen panel can incorporate more control functions, including entry of data into the system's PLC and presentation of prompts and text instructions in the user's language.
Prospective users of the Model RX-400 or other manual or automated blast systems are encouraged to submit sample components for free testing in the application engineering laboratory at the manufacturer's Saratoga Springs, New York, factory.
