CNC milling & turning

CNC custom processing services

Custom metal and engineering-plastic parts are reviewed from the drawing outward: geometry, material, quantity, critical features, surface finish and inspection evidence determine the manufacturing route.

CNC capability at a glance

What CNC machining work can Jinxi review?

Jinxi reviews CNC machining requirements for nearly all commonly machinable metals and engineering plastics, from approximately 5 mm to 500 mm in overall part size. For selected critical features, tolerance capability can reach ±0.003 mm when the material, geometry, machine route, inspection method and production conditions are suitable. This is a conditional capability, not a blanket tolerance guarantee for every dimension or project.

A Shanghai CNC supplier for ongoing production

CNC machining is Jinxi Precision’s core strength. From our Shanghai factory, we support buyers in Europe and North America with precision manufacturing, quality control and cost-conscious production planning. Our ongoing customer relationships include aerospace businesses in the United States, automotive businesses in Switzerland and shipbuilding businesses in South Korea.

We review requirements from dozens to hundreds of thousands of parts, including repeat orders. This is a project range, not a guarantee that every part or schedule is feasible: material, geometry, tolerances, inspection requirements, production capacity and delivery timing are confirmed for each order. Share your drawing, batch quantity and expected annual demand so we can assess a suitable supply plan.

Processing scope

What this service can include

  • CNC milling for prismatic, multi-face and complex 3D features
  • CNC turning for rotational, threaded and concentric components
  • Multi-axis access review to reduce setups on complex geometry
  • Precision mould, EDM, grinding and secondary-operation coordination where applicable
  • Prototype, low-volume and repeat-production planning from controlled drawings

Buyer inputs

What to include in the RFQ

  1. Latest STEP/DWG/PDF and revision

Material coverageMetals + plastics

Broad coverage across nearly all commonly machinable metals and engineering plastics; confirm the exact grade and condition at RFQ.

Tightest stated tolerance±0.003 mm

Available for suitable features when geometry, material, setup, datum strategy and measurement method support it.

Part size range5–500 mm

Approximate overall range; final fit depends on part shape, workholding, machine travel and required feature access.

Machinable materials

Broad metal and engineering-plastic coverage

  • Metals: aluminum, stainless steel, carbon steel, tool steel, brass, copper, titanium and other machinable alloys.
  • Engineering plastics: POM/Delrin, PEEK, nylon, PVC, acrylic, PTFE and other machinable polymers.
  • Specialty grades and heat-treated conditions are reviewed against tooling, deformation, finish and inspection risk before quotation.

Technical data

Project limits must be verified before commitment.

Published ranges help qualify an RFQ; the drawing still determines the approved process and inspection route.

Tolerance confirmation

Feature geometry, material condition, setup count, datum structure and measurement uncertainty are reviewed together.

Envelope confirmation

The 5–500 mm range is checked against workholding, travel, tool access, deformation risk and safe handling.

Evidence confirmation

Inspection reports, material records, traceability and first-article requirements are agreed before production.

Service FAQ

Questions to resolve before commitment.

Can Jinxi quote from a 3D model only?

A 3D model can start the review, but a controlled 2D drawing is preferred for tolerances, datums, notes and acceptance criteria.

What tolerance can be achieved?

Jinxi states capability down to ±0.003 mm for suitable features. Confirmation remains project-specific because geometry, material, setup, feature size, datum strategy and measurement method all affect feasibility.
