High Tolerance Positioning Connection Custom Precision CNC Parts Cnc Machined

Product Overview

Engineered exclusively for high-precision positioning and connection scenarios, this custom aluminum adapter flange is manufactured on 5-axis CNC turn-mill composite centers, built to eliminate assembly backlash, maintain consistent runout, and deliver long-term structural stability under dynamic load.

Core Product Specification Table

Material-Focused Product Introduction

1. Material Performance & Raw Material Control

We only select premium wrought aluminum billet as base stock for all standard adapter flanges, no recycled material, no casting porosity, no hidden internal defects.

• 6061-T6 aluminum: balances excellent machinability, medium tensile strength and corrosion resistance, the cost-effective choice for general automation, packaging equipment and factory automation connection

• 7075-T6 aluminum: ultra-high strength comparable to mild steel, outstanding fatigue resistance, perfect for high-load, high-speed motion, aerospace and automotive test rig scenarios
  【HIGHLIGHT】 All raw material batches come with official material Mill Test Report (MTR) free on request, you get full material traceability for all critical assemblies.

2. 5-Axis Turn-Mill Machining Features

Every adapter flange goes through one-shot full processing on 5-axis turn-mill composite machine, no secondary clamping, no accumulated alignment error:

• Single setup completes all face turning, bore boring, tapping, chamfering and contour milling in one pass

• Zero tolerance misalignment between mating faces, inner bore and bolt circle

• No tool chatter marks, no sharp residual burrs, all transition edges are manually deburred for clean assembly
  【HIGHLIGHT】 Parallelism of two mounting reference faces is guaranteed ≤0.02mm across full part diameter, no extra shimming or manual adjustment needed on your production line.

3. Core Part Competitive Advantages

This custom precision flange directly solves common pain points of off-the-shelf standard flanges:

• 100% custom geometry that perfectly matches your existing shaft, equipment interface or legacy part drawing

• Concentricity between inner bore and outer reference circle ≤0.01mm, no eccentric runout even under 10,000+ RPM high speed rotation

• Higher stiffness and lower weight than equivalent steel flanges, reduces total moving mass for motion systems
  【HIGHLIGHT】 Direct drop-in replacement for your obsolete, damaged or hard-to-source flange parts, no redesign or modification to your existing equipment required.

4. Typical Industrial Application Scenarios

This custom positioning connection flange is widely deployed across high-precision industries:

• Automation & robotics: joint connection, rotary platform positioning, servo motor shaft adapter

• Semiconductor & electronics equipment: vacuum chamber sealing, wafer transfer module connection

• Aerospace & UAV: test fixture mounting, propulsion system interface, sensor calibration jig

• Medical & optical equipment: imaging module alignment, precision instrument base connection

• New energy & EV: motor housing adapter, battery module positioning plate, end-of-line test bench fixture

Multi-Material Diversified Machining Capability

Beyond premium aluminum alloys, our 5-axis CNC turn-mill workshop supports full custom precision machining on a wide range of engineering materials to match any special working condition you require:

• Engineering plastic materials: POM/Delrin, PEEK, PC, acrylic, 30% glass fiber reinforced nylon

• Special non-metal: technical ceramics, carbon fiber composite parts (custom order available on request)

FAQ (Frequently Asked Questions)

1. Q: Can I order a fully custom adapter flange that does not exist as a standard part?
   A: Yes. We are a 100% custom CNC machining factory, all flanges are manufactured strictly per your 2D/3D CAD drawing, no mandatory minimum order quantity, supporting 1-piece prototype all the way to 10,000+ unit mass production.

2. Q: I don’t have a finished CAD drawing right now, can you still make the flange for me?
   A: Absolutely. Our engineering team can finalize the full manufacturable drawing for free from your basic parameters: shaft diameter, bolt circle dimension, total thickness, load requirement and working environment, before we start any machining work.

3. Q: Can you guarantee the tight tolerance requirement for my high-speed rotary or vacuum application?
   A: Yes. All your critical specified tolerance items will be marked on our individual inspection sheet, and full CMM (coordinate measuring machine) inspection report can be provided free on request before shipment.

4. Q: Do you offer different surface treatment and marking options for aluminum flanges?
   A: We cover all common industrial surface treatments for aluminum: hard anodizing, clear/color anodizing, chromate conversion coating, bead blasting, electropolishing, PTFE dry lubricant coating, and custom laser engraving / part marking.
