CNC MILLING

Precision CNC Millingfor Complex Custom Parts

Custom 3-, 4- and 5-axis milled parts from prototype to low-volume production, with tolerances down to ±0.01 mm after drawing and process review.

CNC milling process and prismatic machined parts

Five Milling Configurations. One Production Partner.

From straightforward prismatic parts to indexed and simultaneous multi-axis work, we match the machining route to part geometry, tolerance and delivery requirements.

Critical features down to ±0.005 mm may be supported after drawing, material, process and inspection review.

Multi-axis part size and final delivery date are confirmed against the rotary envelope, fixture strategy and stock availability.

Materials for Precision CNC Milling

OUJI specializes in aluminum, iron and stainless alloys, with experience across metals and engineering plastics. Drawing-led planning supports dimensional and deformation control down to 0.01 mm.

CNC milled aluminum, iron alloy and stainless steel parts

CORE EXPERTISE

Aluminum, Iron & Stainless Alloys

Deep milling experience for housings, brackets, tooling plates and structural parts. Material-specific fixturing, cutting and inspection strategies help control dimensions and deformation.

  • 6061 & 7075 Aluminum
  • 304 & 316 Stainless
  • Alloy & Tool Steels
CNC milled parts made from a broad range of metals and engineering plastics

BROADER EXPERIENCE

Dozens of Machinable Materials

Multi-process experience spans copper, titanium, nickel, magnesium and engineering plastics, supported by drilling, tapping, boring, finishing and dimensional inspection.

  • Copper & Brass
  • Titanium & Nickel
  • Engineering Plastics

Fast Prototyping. Controlled Production.

OUJI combines the speed needed for new-part development with a separately managed system for stable batch production—so neither workflow has to compromise the other.
01

RAPID PROTOTYPING

Fast Routing for New Parts

Each drawing is translated into material, setup, toolpath, inspection and finishing tasks, helping the team route work quickly and respond to design changes.

  • Process plan created after drawing review
  • Capacity-aware routing to suitable machines
  • Short feedback loops for revisions and iteration

BATCH PRODUCTION · 500+ PARTS

Dedicated Control for Repeat Production

Orders of 500 parts or more do not run through the prototype workflow. They enter an independently managed production system with separate workshop planning, personnel, scheduling, process control and quality gates.

  • Prototype and production orders managed separately
  • Dedicated personnel, planning and production control
  • Locked processes, inspection gates and traceable output

APPLICATION-LED CNC MILLING

CNC Milling for Demanding Industries

OUJI supports precision components from prototype through controlled production. Each project is planned around material behavior, tolerance, inspection, repeatability and delivery—not a one-size-fits-all machining route.
