Advanced Thin-Wall Machining Solutions

Precision deformation control for aluminum alloy components with wall thickness down to 0.3mm

The Thin-Wall Machining Challenge

Deformation control in aluminum alloy components requires specialized expertise and technology

Thermal Deformation

Heat generation during machining causes uneven thermal expansion in thin-wall structures, leading to dimensional inaccuracies exceeding 0.2mm in critical aerospace components.

Chatter & Vibration

Low structural rigidity results in harmonic vibrations that cause surface finish defects, tool breakage, and dimensional inaccuracies up to 0.15mm in automotive applications.

Residual Stress

Material stresses introduced during casting or forging cause warping when released during machining, leading to post-machining deformation exceeding 0.3mm in medical device components.
