Case

FIWOK METALWORKS specializes in high-precision cnc milling for the Semiconductor & Industrial Automation sectors, operating from our advanced facility in Shenzhen, China. Since 2012, we have accumulated 14+ years of industrial expertise in build-to-print contract manufacturing for intricate prismatic components, base plates, and structural carrier frames. We leverage 3-axis CNC milling machines to process premium aluminum alloys, notably Aluminum A7075-T651, delivering exceptional geometric accuracy. Our robust process control system guarantees strict material source traceability and comprehensive dimensional batch inspection reports for every production run. 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 precision Aluminum 7075 fixture base plate used for industrial fixture, equipment assembly, and positioning systems. The project focused on multi-hole positioning, flatness control, drawing-based inspection, and low-to-medium volume production support.
