Product Description

Aerospace-level technical standards

The Sanluo Precision factory strictly adheres to the aerospace CNC machining technical standards when conducting processing. The processing accuracy reaches IT6 and IT5 levels, with form and position tolerances of ±0.002mm, and the surface roughness is no more than Ra0.2μm. It masters the low-stress cutting and constant-temperature processing technologies for aerospace-specific materials such as titanium alloy TC4, high-temperature alloy GH4169, and aluminum-lithium alloy. It controls the deformation and residual internal stress of the materials to ensure the long-term use of the parts. Special equipment and environmental conditions include the DMU85 five-axis machining center from DMG MORI and the VF series vertical machining center from Haas. There is a dedicated production processing area with strict management systems for personnel and raw material entry and exit.

Quality Traceability System

As a professional precision aerospace CNC machining manufacturer, Sanluo Precision Company has a well-established quality traceability system. Each part has a complete quality file, including the batch number of raw materials, heat treatment reports, processing parameters, and test data throughout the process are all stored in the file. Non-destructive testing technologies such as spectral analysis, ultrasonic testing, and X-ray inspection are used to ensure the internal and external quality of the parts. All key dimensions are measured using ZEISS three-coordinate measuring machines, and the test reports comply with AS9100D standards. The company has provided customized NC machining services for important components for multiple aerospace models, with a qualification rate of over 99.8%.
