Plate 4 shows an example of the controlled shot peening of aeroengine fan blade "roots", using a Vacu-Blast programmable multi-nozzle array. Precision movement of the six peening nozzles and other peening parameters are governed and monitored continuously by the company's latest "Vacutrol II" surface treatment control system which operates via a PC under Windows. The fan blades are processed to pre-determined parameters to the latest stringent MilSpec aerospace standards.

A similar controlled multi-nozzle technique can also be used for a wide variety of other precision surface preparation or treatment applications on "critical" or complex components. These include surface preparation for thermal spraying, etching surfaces prior to bonding or the application of wear or corrosion resistant coatings and the delicate cleaning of intricate mould surfaces.

The nozzle arrays and the associated control system can be fitted or retro-fitted to new and existing Vacu-Blast cabinet machines. These not only ensure optimum accuracy when shot peening or abrasive blasting: but also maximise production efficiency and throughput ­ producing long-term cost benefits.

Up to ten or more nozzles ­ suction or pressure fed ­ can be fitted to an array for use with all types of abrasive blast media, from plastic and organic materials such as wheat starch, to steel shot and glass and ceramic beads.
