OEM Precision Metal Parts, Stainless Steel CNC Machining
OEM precision metal parts in stainless steel, aluminum, titanium and brass. Custom CNC machining, milling, turning, threaded components, sleeves, shafts and brackets from drawings or samples.
Turn Mill Machining, Custom Non-Standard Metal Parts Service
This CNC machining portfolio presents a turn-mill combination approach for producing complex non-standard components from customer drawings, CAD files, samples or BOMs. The image shows brackets with holes, cylindrical sleeves, flanged housings, clamp-like parts, linkage plates, slotted plates, threaded fittings, knurled knobs, shafts, rings, covers and small inserts. These forms may require a coordinated sequence of turning, milling, drilling, boring, threading, slotting, chamfering and deburring; the final route depends on the approved design. The service supports turn mill machining, custom non standard metal parts and a one stop CNC machining service for prototypes, small batches and OEM assemblies. Material, tolerance, finish, inspection and delivery are confirmed per project.
Custom CNC Screws, Precision Machine & Self-Tapping Fasteners
Socket-head, slotted, Phillips, countersunk, pan or rounded-head screws, long threaded forms and pointed self-tapping styles. Silver, black, gold, purple, blue and green appearances are visual references only; material and finish require specification. The service is suitable for custom CNC screws, precision machine screws and custom self tapping screws for machinery, fixtures, equipment, furniture hardware, electronics and OEM assemblies. Submit a drawing, sample or BOM to confirm thread, head, drive, length, tolerance, surface, treatment, inspection and packing.
Custom CNC Fastener Parts & OEM Screws, Nuts and Washers
Customers can submit a 2D drawing, 3D CAD file, sample or BOM for project review. The service can cover CNC turning, CNC milling, drilling, tapping, threading, deburring, surface treatment and assembly-oriented packing where applicable. The actual material, finish, size, tolerance, quantity and delivery plan are confirmed from the approved specification.
Rapid Prototyping, OEM ODM CNC Machining Service
Professional rapid prototyping and OEM ODM CNC machining for stainless steel, aluminum and customized metal parts. CNC milling, turning and 5-axis fabrication from drawings, CAD files or samples.
Custom Stainless Steel CNC Turning Parts & Waterjet Cutting
The service can combine material cutting and CNC secondary operations. Waterjet cutting may be considered for suitable flat metal profiles, while CNC turning is suited to coaxial shafts, rings, sleeves and threaded bodies. CNC milling adds slots, flats, pockets, holes and irregular faces. A combined process plan can reduce extra handling when a part requires cut stock, turning, milling, drilling, threading and inspection. Material grade, heat treatment, surface finish, critical dimensions and inspection documents should be stated in the RFQ.
5 Axis CNC Machining, Custom Precision Milling Parts
These custom precision milling parts suit buyers needing small components rather than catalog hardware. The image shows compact parts with external/internal threads, stepped bodies, bores, radial holes, slots, clamps and shoulders. Parts appear silver or gold-colored; exact material must be confirmed from the drawing.

The service supports 5 axis CNC machining for multi-face or angled access, plus milling, turning, drilling, boring and threading. It produces small aluminum CNC machined parts, prototypes, replacement parts and low-volume assemblies. Final grades, tolerances, finishes and inspection requirements are confirmed per project.
Aluminum Stainless Steel CNC Parts, Custom OEM Machining
This drawing-based service produces functional components rather than catalog-only hardware. The images show stepped shafts, sleeves, flanged rings, gear-like parts, threaded connectors, hollow housings and custom brackets.

Our custom CNC machined metal parts can be developed from drawings, CAD files or samples. The CNC machining service for aluminum and stainless steel supports housings, fittings, shafts and assembly hardware. Custom CNC turning and milling parts can combine rotational features with holes, flats, pockets, slots and mounting faces. Final material grades, tolerances, finishes and inspection requirements are confirmed per project.
Custom CNC Machining, Anodized Aluminum & Prototype Parts
We provide a one-stop custom CNC machining service for engineers, OEM buyers and manufacturers. Send 2D/3D drawings or samples for DFM review and prototype planning. The images show anodized brackets, aluminum housings, flanges, rings, turned shafts, threaded fittings, heat sinks and gears.

Our service produces anodized aluminum CNC parts and CNC machining prototype parts, plus stainless steel parts, CNC turning, milling and Swiss-type machining. The images show drawing review, raw-material procurement, FAI, machining, IPQC, dimensional inspection, batch inspection, surface treatment, final inspection and delivery. Exact grades, tolerances, finishes and schedules are confirmed per project.
CNC Machining Prototype, Rapid Aluminum & Stainless Steel Parts
Our custom CNC machining prototype service supports engineers, product developers, maintenance teams and OEM buyers. Send a 2D/3D drawing or approved sample for geometry review and prototype planning. The images show threaded shafts, stepped pins, sleeves, flanges, bushings, housings, connectors and brackets.

This rapid prototyping CNC service produces CNC aluminum stainless steel parts for one-piece development, fit checks, functional testing, design verification and small batches. The image states 5–7 day prototyping, free DFM feedback, one-piece MOQ and 100% QC before shipping. Final grade, finish, tolerance and inspection documents are confirmed per project.
