Torus A521 Fan Track Boring Machine

Brought to you by Torus, our specialist testing brand, the Torus A521 Fan Track Boring Machine was developed to produce an accurate fan track bore in a fraction of the time, while also reducing labor and operation costs.

With the ever increasing need for Turbo Fan engine efficiency in mind, Torus have developed the A521 CNC Fan Track Boring machine. The machine produces an accurate fan track bore in a fraction of the time of any other system, while also at the same time requires fewer personnel for set-up and operation.

Increase efficiency

Torus’ A521 Fan Track Boring machine features a CNC control of the cutting path, negating the need for expensive fixed profile templates prone to inaccuracy and wear. Additionally, profiles can be easily edited from fan track profile CAD files giving unprecedented flexibility, dramatically reducing lead time and costs for new profile variants.

The integrated measurement system is utilized for pre-machining inspection, optimizing the cutting sequence to give ultimate machining efficiency. Of course, the same system is also used for final inspection, producing a measurement report tailored to the end user’s requirement to include:

• Full profile scanning
• Gauge point measurement
• Full radial scanning

The reports can be networked for full traceability.

Versatility of the A521 Fan Track Boring machine

Ideal for Aerospace applications, the A521 Fan Tracking Boring Machine is capable of machining partial fan tracks (maybe required at overhaul) and full fan tracks (typical to engine production). There is also the facility to custom cut profile diameter to match the fan set.

Integrated vacuum extraction system removes dust directly from the cutting tip, leaving the working environment free from contamination, meaning that the cutting operation can be conducted in the engine build area.

Transportable through the factory once folded away into its compact position on the wheeled base.

All interlocked guarding is integrated within the trolley, and once machine is located, is quickly & easily positioned.

Loading of the machine on to the engine is effortless; the pneumatic manipulator is balanced to give the boring bar an almost weightless feel. This of course, also ensures there are minimal external forces on the LP shaft or through the fan case during machining.
