3-axis and multi-axis CNC milling for housings, plates, brackets, cavities, prototypes and complex milled components.
Custom CNC Turning Services
CNC turning for shafts, bushings, threaded fittings, round metal products and precision cylindrical components.
CNC Machining for Prototyping to Production
Whether you need rapid machining, a small pilot batch or repeat OEM manufacturing, our CNC machining services scale with your project while maintaining practical tolerances, documented requirements and clear communication.
China's CNC Machine Shop. Ship Globally
Yishang helps international OEM buyers move from drawing to machined products without managing too many suppliers. We support sample approval, batch production, finishing, packaging and export communication from one coordinated source.
For buyers, the pain is rarely machining alone: it is slow feedback, unclear tolerance risk, surface scratches, late rework and products that do not assemble. Our CNC machining workflow is built to reduce those risks before production starts.

Precision CNC Machining Capabilities
Choose the process around product geometry, not around a fixed machine. Our engineering review considers workholding, tool reach, deformation, tolerance stack-up, surface requirements and expected annual demand.
Every capability is confirmed against your drawing before quotation.

From Costly Sourcing Delays to a Stable Repeat Order
A commercial equipment buyer needed machined aluminum housings with cosmetic anodizing, critical mounting dimensions and individual surface protection. Previous suppliers quoted machining and finishing separately, creating unclear responsibility when appearance defects occurred.
One Drawing Review, One Coordinated Delivery
Yishang reviewed datum selection, cosmetic zones and anodizing allowance before the first sample. After approval, machining, finishing, inspection and protective packing were controlled under one order.
Buyer value: fewer handoffs, faster approval, more consistent appearance and a repeatable purchasing route for future batches.
Fewer Supplier Handoffs
Machining, finish and packing coordinated together.
Repeat-Order Ready
Approved requirements retained for the next batch.

Quality Assurance for CNC Machining Services
CNC machining problems usually show up as tolerance drift, wrong material, burrs, scratches, missing threads or products that fail assembly. Yishang focuses on early DFM review, first-piece confirmation, critical dimension checks, surface protection and export-ready packing.
For repeat orders, we keep production notes so future batches are easier to control.
DFM Review
Tool access, tolerance risk, material choice and finish planning before quoting.
Dimension Check
Critical dimensions checked against drawing requirements before shipment.
Surface Review
Burrs, scratches, coating risk and visible features reviewed before packing.
Export Packing
Protect machined products from collision, moisture and surface damage.
Design Guidelines for CNC Machining
Good CNC design reduces tool changes, setup time, chatter, scrap risk and inspection cost. Final recommendations depend on material, geometry and function.
Use practical corner radii instead of sharp 90-degree internal corners; larger radii allow stronger, faster cutting tools.
Keep pocket depth reasonable relative to tool diameter; deep narrow cavities increase vibration, deflection and cycle time.
Specify standard thread sizes, required engagement and whether full-depth threads are functionally necessary.
Avoid unnecessarily thin walls, especially in aluminum; thin features can distort during clamping, machining or finishing.
Apply tight tolerances only to functional interfaces and define datums clearly so inspection matches design intent.
Mark visible zones and acceptable appearance standards so handling, finishing and packing can be planned before production.

CNC Machining Services FAQs
What is CNC machining?
CNC machining is a subtractive manufacturing process that uses computer-controlled tools to remove material and create precise custom products or components from metal or plastic.
What CNC machining services does Yishang offer?
Yishang supports CNC milling, CNC turning, drilling, tapping, deburring, finishing coordination and inspection support for OEM projects.
Can you make both prototypes and production orders?
Yes. We can support prototype samples, pilot runs and repeat batch production depending on material, finish, tolerance and quantity.
What files should I send for a CNC machining quote?
Please send STEP, STP, IGS, X_T, DWG, DXF or PDF files, plus material, quantity, surface finish, tolerance notes and target delivery date.
How fast can you quote CNC machining projects?
For complete drawings, we target fast RFQ feedback. Complex products may need DFM review before a final quote.
Can you help with surface finishing and assembly checks?
Yes. We can coordinate finishing, deburring, surface protection, simple assembly checks and export packing based on project requirements.
What is the difference between CNC milling and CNC turning?
CNC milling uses rotating cutting tools and is suited to plates, housings, pockets and multi-sided geometry. CNC turning rotates the workpiece and is efficient for round products such as shafts, sleeves and bushings.
What tolerances can you hold?
General tolerances are confirmed by drawing and material. Many features are produced around +/-0.05 mm, while selected critical features may target +/-0.01 mm after engineering review.
How can I reduce CNC machining cost?
Avoid unnecessarily tight tolerances, deep narrow pockets, sharp internal corners and difficult tool access. Standard materials, realistic surface requirements and flexible quantities also help reduce cost.
Can you protect cosmetic surfaces during production and shipping?
Yes. Identify cosmetic zones on the drawing. We can plan handling, surface inspection, protective film or individual wrapping and export packing around appearance requirements.
