One-Piece Flow Blast System

Guyson Corporation’s new model rotary indexing spindle-blast machine is for shot peening, descaling, deburring, finishing, surface preparation and other impact treatment operations that require 360-degree coverage of components. The downsized RXS-400 is especially suitable for single-piece flow production. The rigidly welded chassis of the machine’s cabinet is 30" wide and 36" deep, so the automatic blast cabinet presents a narrow profile for tight work cell layouts.

Guyson Corporation’s new model rotary indexing spindle-blast machine is for shot peening, descaling, deburring, finishing, surface preparation and other impact treatment operations that require 360-degree coverage of components. The downsized RXS-400 is especially suitable for single-piece flow production.

The rigidly welded chassis of the machine’s cabinet is 30" wide and 36" deep, so the automatic blast cabinet presents a narrow profile for tight work cell layouts. The system's rotary table is mounted on a precision 180-degree cam indexer and has two rotary spindles to which components are fixtured. Loading and unloading components can be done during the blasting cycle.

Inside the cabinet, the spindle is rotated at controlled speed, and the component is exposed to blast from multiple nozzles that are adjustably bracketed at the correct angles on a programmable ballscrew and ballnut linear traverse. Spindle speed, traverse speed, stroke and other process parameters can be quickly adjusted with a few finger strokes at the touchscreen control panel.

The touchscreen human-machine interface simplifies selection or entry of dimensional and process data by graphically representing system functions on multiple displays configured by a controls engineer. It also allows the machinery designer to provide visual prompts and text instructions to guide the operator, including explanation of sensor-triggered system faults and corrective actions. Numerous buttons, switches, readouts and other wearable electrical or electronic components have been eliminated.
