CNC turning services for shafts, bushings, fittings and other rotational parts, reviewed against your diameters, threads and datums.
✓ Diameters and fits reviewed for assembly ✓ Threads and related features clearly specified ✓ Inspection requirements aligned across batches
Define how diameters, shoulders, bores and threads relate to the mating assembly—not just nominal size.
For precision CNC turning, diameter tolerance, geometric control and surface roughness are separate requirements. Each should be defined for the relevant feature.

Show non-turned features relative to the turned surfaces so the complete route can be reviewed.
Define hole size, depth and location relative to the shaft axis or shoulder. Identify internal intersections that require deburring.
Show feature width, depth and orientation. Mark any angular relationship to cross-holes, threads or other assembly features.
Critical fits or surface requirements may need grinding or another finishing operation. The sequence is reviewed around material condition and final acceptance requirements.

Engineering Consultation That Reduces Manufacturing Risk At Starway, engineering involvement starts before production begins. Our engineers work closely with customers to review drawings, tolerances, materials, and manufacturing feasibility, identifying potential risks early and proposing optimized solutions. By integrating engineering and sales teams, we ensure that technical decisions are accurately translated into cost, lead time, and production plans — avoiding surprises during execution.
New project success depends on speed, accuracy, and adaptability. Starway operates a dedicated project development team combining engineering, prototyping, and quality control. This allows us to deliver prototypes within 1–2 weeks, validate manufacturability quickly, and resolve technical challenges through real production trials — not assumptions.
On-time delivery and consistent quality are not outcomes — they are engineered results. All orders are managed through our MES system, enabling real time production tracking, quality traceability, and cross department coordination. This system-driven approach allows us to proactively manage risks, maintain schedule integrity, and keep customers informed with accurate production data.
At Starway, Easy Shipping is another key advantage. Our goal is to make customers' shipping easy, safe, and fully trackable. Our professional logistics team helps our customers handle all types of shipments — both air and sea — including EXW, FOB, CIF, DDP, etc. Our shipping system enables us to track and monitor all shipments in transit, ensuring they arrive safely and on time. Our customers are updated regularly with their shipping status.
Stainless steels are widely used in CNC machining due to their excellent corrosion resistance and strength.
Carbon and alloy steels offer high strength and durability for mechanical components, shafts, and industrial parts.
Aluminum alloys are lightweight, corrosion-resistant, and easy to machine. They are commonly finished with anodizing or coating to enhance surface durability.
Titanium and other high-strength alloys provide exceptional strength-to-weight ratios and corrosion resistance.
Engineering plastics such as POM (Delrin), Nylon, and ABS are easy to machine and lightweight.
Copper and brass are ductile and offer good thermal and electrical conductivity. They are often used in electrical components
CNC Turning is used to produce high-precision custom parts for industries such as automotive, aerospace, and electronics.
Common materials include aluminum, stainless steel, brass, titanium, ABS, and POM.
