Case

FIWOK METALWORKS, a Shenzhen contract manufacturer with 14+ years of industrial expertise, presents Case 004: precision 5-Axis CNC Machining of an Aluminum A6061-T6 Thin-Wall Prismatic Enclosure for a 100 Pieces run. Sourced from raw saw-cut plate stock to relieve residual stresses and maintain stability during high-feed metal removal, the component features a deep-cavity layout with thin partitions. The process holds parallelism within 0.02 mm to datum A and position tolerance within a 0.02 mm cylindrical zone to datums A, B, and C. Full material traceability is maintained via mill test reports alongside dimensional batch inspection reports. First Article Inspection (FAI) via in-house CMM ensures alignment within automated optical and semiconductor carrier assemblies.

FIWOK METALWORKS, a Shenzhen contract precision manufacturer with 14+ years of industrial expertise, presents Case 021 covering custom Precision Step Punch Pins. The project utilized Swiss Turning (Sliding Headstock) to machine High-Carbon Tool Steel (AISI D2, heat-treated condition) specified for wear resistance into multi-stepped segments. This batch run of 5,000 Pieces met dimensional specs for linear deviation and runout mitigation. FIWOK maintains lot-based material traceability with mill test reports and batch quality documents. Certified third-party dimensional inspection and hardness reports are provided upon explicit engineering request to verify compliance for tooling constraints in high-wear stamping die applications.

We optimize production methodologies to ensure exceptional consistency for low-volume prototypes and medium-to-large batches.

FIWOK METALWORKS, a premium contract hardware manufacturer based in Shenzhen with 14+ years of industrial expertise, presents Case 031: the precision 3-Axis CNC Milling of an Aluminum A6061-T6 Mounting Bracket for a 200 Pieces repeat production run. Sourced from raw saw-cut plate stock to relieve rolling-induced residual stresses and maintain stock stability during high-feed metal removal, this component features dynamic trochoidal pocketing and rigid symmetric face milling. This process controls planar flatness to within 0.02 mm and holds a position tolerance within a 0.02 mm cylindrical zone relative to the specified datum reference frame established by primary datum A, secondary datum B, and tertiary datum C per ASME Y14.5-2018. Full material source traceability is maintained with comprehensive mill test reports, alongside standard dimensional batch inspection reports.

Engineering project study of Case 015 by FIWOK METALWORKS, highlighting precision CNC milling services for a custom Aluminum 7075 multi-cavity structural component. Operating from our Shenzhen facility since 2012 with 14+ years of B2B contract manufacturing expertise, our machine shop utilizes multi-axis CNC milling centers to manage specialized tool rigidity control, deep cavity side-hole toolpath configurations, and structural pocket geometry stability. This production run of 100 pieces was manufactured with zero product development involvement, relying strictly on customer blueprints to hold tight linear tolerances down to ±0.005mm based on complex features. Quality gating was executed via digital height masters, VMS optical projectors, and micrometers to provide material source traceability and batch dimensional inspection logs prior to post-machining bead blasting and anodizing.

This case demonstrates CNC milling of a PEEK laser equipment mounting block used in laser equipment and optical system applications. The project involved high-volume PEEK CNC machining with 20000 pcs produced within a 30-day lead time. Typical tolerance was controlled according to drawing requirements, with ±0.02 mm applied to specified critical dimensions.
