Changzhou Fenglan New Materials Co., Ltd.

Computer Numerical Control machining

-- Steady & Reliable Manufacturer --

Introduction

CNC (Computer Numerical Control) machining is a subtractive manufacturing process in which pre-programmed software controls the movement of machine tools — lathes, milling spindles, drill heads, and more — to remove material from a solid workpiece and produce a finished part to precise dimensional specifications.

Fenglan has operated CNC machining centers since our founding in 2010, continuously investing in equipment and process capability to serve automotive, industrial, and electrical precision part buyers worldwide. Our shop floor runs multi-axis turning centers, 3- and 4-axis vertical machining centers, and Swiss-type CNC lathes, giving us the flexibility to machine small complex parts (sub-10 mm) through to medium-size components (up to 600 mm).

We work in a broad range of materials — aluminum alloys, brass, stainless steel, carbon steel, titanium, copper, and engineering plastics — and support both high-volume production runs and low-volume prototype quantities from a single piece upward.

Applications

  • Automotive: Engine components, transmission parts, brake system housings, sensor brackets, and EV battery module hardware.
  • Industrial Machinery: Pump bodies, valve seats, manifold blocks, precision shafts, and bearing housings for process equipment.
  • Electrical & Electronics: Heat sinks, connector housings, motor shaft assemblies, and EMI shielding enclosures.
  • Medical Devices: Surgical instrument components, implant trial pieces, diagnostic equipment housings, and fluid-handling manifolds.
  • Aerospace & Defense: Structural brackets, actuator components, and precision housings where material traceability and tight tolerances are non-negotiable.
  • Consumer Products: Camera mounts, drone frames, bicycle components, and wearable device enclosures where surface finish and dimensional accuracy drive user experience.

Advantages

  • High Repeatability: CNC eliminates operator variability. Once a program is proven, every subsequent part is identical — critical for interchangeable assemblies and mass production.
  • Tight Tolerances: Achievable tolerances of ±0.005 mm on critical features surpass the capabilities of casting, forging, or 3D printing for precision-critical applications.
  • Material Flexibility: One machining center can process aluminum, brass, steel, and plastics with tooling changes only — no re-investment in new equipment per material.
  • Scalable Volumes: Economical from single prototypes (no tooling cost) through millions of production pieces, with per-unit cost declining as volume rises.
  • Complex Geometry: Undercuts, internal threads, cross-holes, and compound curves that cannot be cast or forged are routinely achievable with multi-axis CNC.
  • Fast Turnaround: Digital workflow from CAD file to machined part in as little as 3 days for prototypes, supporting agile product development cycles.

Payment & Shipping

Payment Terms: We accept T/T (wire transfer), L/C at sight, PayPal, and Western Union. A 30% deposit is required before production begins, with the remaining 70% settled before shipment. For established long-term customers, flexible credit arrangements can be discussed on a case-by-case basis.

Lead Time: Standard production lead time is 7–15 business days after deposit confirmation. For urgent orders, expedited scheduling may be available — please contact our sales team to check availability.

Shipping & Logistics: We ship worldwide via DHL, FedEx, UPS, TNT, and by sea (LCL or FCL). Incoterms supported include EXW, FOB Ningbo/Shanghai, CIF, and CFR. The most cost-effective option is selected based on order weight and destination.

Packaging: All items are individually inspected, then packed in anti-rust film and foam-lined export cartons. Custom branding, inner packaging, and labeling are available on request. Packaging fully complies with international freight standards.

Quality Assurance: Every shipment is accompanied by an inspection report and, where applicable, material certificates (e.g., RoHS, REACH). We support third-party inspection arrangements (SGS, BV, etc.) if required.

FAQ

  • Q: What file formats do you accept for CNC machining orders?
  • A: We accept STEP (.stp/.step) and IGES (.igs) for 3D models, and DWG/DXF or dimensioned PDF for 2D drawings. STEP is preferred as it preserves geometry most reliably. Please always include a drawing with critical tolerances, surface finishes, and material callouts — 3D files alone are not sufficient for production orders.
  • Q: What is the tightest tolerance you can hold?
  • A: With our precision CNC turning centers and post-machining grinding, we can hold ±0.005 mm on bore diameters and shaft ODs. Flatness and parallelism of ±0.01 mm are achievable on milled surfaces. Tolerances tighter than ±0.005 mm require grinding or lapping and additional lead time — please discuss your requirements upfront.
  • Q: Can you machine exotic materials like titanium or PEEK?
  • A: Yes. We regularly machine Ti-6Al-4V (Grade 5) titanium and engineering plastics including PEEK, Delrin (POM), and PTFE. These materials require specialist tooling and cutting parameters — add-on cost is included in our quotation.
  • Q: Do you offer design-for-manufacturability (DFM) feedback?
  • A: Yes, our engineering team reviews every new part file and flags features that may increase cost or risk (e.g., unnecessary tight tolerances, very deep thin slots, sharp internal corners). DFM feedback is provided free of charge before you confirm the order.
