Polishing and smoothing of aerospace parts with Stream Finishing Machine

Highly efficient, ultra-reliable engineering is crucial in the aerospace industry, which is why
manufacturers expect their components and production processes to meet such stringent
requirements. Very low surface roughness values as well as rounding and/or deburring processes
play a fundamental role in significantly reducing friction in the engine.
Requirements:
■ Homogeneous smoothing - “Super Finishing” -
down to Ra 0.4 μm - 0.04 μm
■ Extremely low process variation of 1 μm compared to other processes with ~ 5-10 μm
■ Deburring and even rounding to a defined radius in one operation
■ Only minimal changes to the workpiece geometry during processing
Stream finishing solution:
■ Higher efficiency due to less friction
■ Applicable to milled, blasted and coated blades
■ Pre- and post-processing (smoothing) of coated parts
■ Simultaneous deburring while smoothing if necessary
■ High output by clamping up to 5 parts simultaneously
■ Maximum part dimensions: Ø 650 mm, l = 650 mm, m = 200 kg
■ Surface levelling of milling grooves
