Custom Aluminum Diagonal Serrated Knurled Bushing CNC Mill-Turn Composite

Our custom 6061 aluminum diagonal serrated knurled bushing is fully processed on CNC mill-turn machine in one single setup, eliminating secondary clamping errors. Made of standard 6061 aerospace grade aluminum alloy, the part adopts special diagonal zigzag serrated knurling on outer surface to deliver reliable anti-slip performance.

The surface is finished with gold hard anodizing treatment, improving surface hardness, abrasion resistance and anti-corrosion performance while maintaining stable color that resists fading.

As a professional precision machining manufacturer, we provide custom service and OEM manufacturing for all kinds of mill-turn bushing, sleeve and insert components. We can produce parts strictly following your technical drawings, samples and tolerance requirements for diverse mechanical assembly projects.

This anti-slip knurled insert bushing widely applies to automation equipment, instrumentation, consumer electronics, power transmission assemblies, fixture & tooling, medical device accessories, and general mechanical connection assemblies. It serves as positioning, fastening and anti-slip lining sleeve for precision mechanical assembly.

We provide full custom service and OEM manufacturing for CNC composite machining parts. Customers can submit 2D/3D drawings or physical samples for quotation. We support customization on material selection, dimensions, knurling patterns, tolerance range, anodizing colors and surface finish. Our engineering team reviews drawings and offers technical suggestions before mass production. Small batch and large volume orders are both accepted.

• One-time CNC mill turn forming avoids repeated clamping deviation, solves poor concentricity and low precision pain points.
• 6061 aluminum alloy with stable mechanical property, effectively reduces part deformation under assembly stress.
• Gold hard anodized coating features strong adhesion, solves easy wear, oxidation and color fading issues.
• Custom serrated knurling design delivers stable anti-slip performance to prevent loose fitting during operation.
• Strict tolerance control meets high-precision assembly requirements, eliminates mismatching problems in finished assembly.

We implement full quality control throughout the whole production flow. Raw material inspection for aluminum alloy certification, in-process dimensional checking by calipers and micrometers, finished product inspection for dimension, surface finish and knurl quality. All custom machined parts are inspected before packing. We can provide inspection reports upon request for OEM orders.

Lead Time: Sample order: 3-7 working days; Mass production: 7-15 working days based on order quantity and custom requirements.

Shipping: Support express, air freight and sea freight. We cooperate with reliable logistics providers. We carefully pack precision CNC machined components to prevent scratch and damage during transit.

1. Can I get custom dimensions and different knurling patterns for this aluminum bushing?  Yes, we are a manufacturer with custom & OEM service, we can adjust size, knurl style, tolerance and surface finish per your drawings.
2. What tolerance can your CNC mill turn machining achieve?  We can hold tolerance from ±0.01mm to ±0.03mm, tighter tolerance is available upon special requirement.
3. Can you make samples before mass production?  Sure. We support sample production for validation before bulk OEM order.
4. What file formats do you accept for custom machining?  We accept STEP, IGES, SolidWorks, PDF 2D drawings for quotation and CNC programming.
5. Is the gold anodizing wear-resistant?  Gold hard anodizing offers excellent abrasion resistance and anti-oxidation performance, not easy to fade under normal working environment.
