CNC Milling Service for Materials, Tolerances and Quality Support

  • Our CNC milling service supports aluminum, stainless steel, brass, copper, titanium, and engineering plastic parts for prototypes, small batches, and production orders.
  • For each CNC milling project, we review 2D drawings, 3D models, material requirements, tolerance requirements, surface finish needs, and key machining features before quotation.
  • CNC milling is suitable for housings, plates, brackets, fixtures, flanges, heat sinks, mechanical frames, and custom precision components.
  • Surface finishing and inspection can be arranged before shipment according to customer drawings and common quality management standards.
  • This helps customers confirm CNC milling quality and reduce communication risks before shipment for prototype and batch production orders worldwide.

What Is CNC Milling?

CNC milling is a subtractive manufacturing process that uses rotating cutting tools to remove material from a solid block. It is ideal for producing parts with flat surfaces, pockets, slots, holes, threads, contours, and complex mechanical features.

At iPrecision CNC, our 3-axis, 4-axis, and 5-axis milling capabilities support both prototype and production parts with consistent accuracy, clean surface finish, and reliable repeatability.

✓ Suitable for complex machined features
✓ Supports prototypes and production runs
✓ Available for aluminum, steel, brass, copper, and plastics

Frequently Asked Questions About CNC Milling

Answers to common questions about CNC milling tolerances, materials, drawings, and lead times.

We machine aluminum, stainless steel, steel, brass, copper, titanium, and engineering plastics such as POM, ABS, PC, nylon, PEEK, and PTFE.

Standard tolerance is typically ±0.05mm. Tight tolerance up to ±0.005mm may be possible depending on material, part size, geometry, and drawing requirements.

We accept STEP, STP, IGS, IGES, STL, X_T, DWG, DXF, PDF, JPG, PNG, and ZIP files. For accurate quotation, 3D files are strongly recommended.

Yes. We provide anodizing, hard anodizing, sandblasting, polishing, plating, powder coating, brushing, and other custom finishing options.
