CNC milling (3, 4 and 5-axis simultaneous), CNC turning and Swiss-type turning, together with the deburring and inspection steps that complete the part. Surface treatment — anodizing, passivation, plating, coating — is not done in house; it is placed with qualified local subcontractors selected for environmental compliance.
Tolerances and surface finish
±0.005 mm typical on 3-axis work and ±0.01 mm standard on simultaneous 5-axis. Surface finish down to Ra 0.2 µm is achievable. The achievable window is confirmed per drawing during a DFM review.
Size range
CNC milling covers workpieces up to 2000 × 1000 mm. Swiss-type turning covers Ø 0.5–20 mm for small-diameter work; conventional CNC turning covers Ø 2–65 mm with lengths to 300 mm. Larger turned envelopes are quoted per part.
Materials
Kovar, tungsten alloys, Permalloy, titanium, Inconel, stainless steel, aluminum, and engineering plastics including PEEK, PI, PTFE, PVDF and POM.
Inspection
Every critical dimension is verified on a Zeiss SPECTRUM CMM, material grade is confirmed by spark-OES spectrometer, and first article inspection reports are available on request.
Certifications
Quality management is certified to ISO 9001:2015 (GICG). For automotive work, our Shenzhen site holds IATF 16949:2016 certification from AENOR, covering the production of LIDAR metal housings and metal spectacle frames.
