Magazon SBU Standard Bench
The Magazon SBU is a standard wet magnetic particle testing bench for production inspection, supplied in Malaysia by Asia NDE.
UK-built 2500A wet horizontal MPI bench with head-shot and coil magnetisation, digital metering and 99-program memory, in daily use across leading UK aerospace companies.
Overview
Key advantages
- In daily use at most of the leading UK aerospace companies.
- Designed and built by Baugh & Weedon in Hereford, UK.
- Nominal 2500A power pack with AC, and HWDC or FWDC waveform options.
- Digital metering of head and flux/coil current in PEAK, RMS or 2xMEAN.
- Microprocessor control with current pre-selection and memory for up to 99 test parameter sets.
- Reduced clamping pressure option to protect delicate components.
- Optional variable transformer control for a sinusoidal waveform where specifications require.
- Stainless steel drain tank on a steel plinth, movable by fork lift truck.
Overview
The Magazon SBU is fitted with a stainless steel drain tank incorporating a fixed headstock and movable tailstock, with the power pack mounted underneath in a heavy duty steel cabinet. Benches can be built to suit your parts and your budget. A “small piece device” can rotate components for easy viewing, and bed-bar mounted support rollers handle heavier test pieces.
Production line options
- Multi-directional “swinging field” – two magnetising circuits operate simultaneously, so defects in any orientation are revealed in a single shot and viewing.
- Automatic sequencing – clamping, inking, magnetising and unclamping run automatically while the operator inspects the previous part.
Ink application & inspection
The bench works with kerosene or water based MPI inks applied by manual spray or timed overhead shower. Excess ink drains to a free-standing stainless steel reservoir with pumped recirculation to keep particles in suspension. For fluorescent inks, UV lamps and a free-standing viewing canopy with front curtains, extractor fan, white light and UV power point are available.
