Custom CNC Turned 6061 Knurled Internal Thread Lock Ring Aluminum Thread Nut Ring for Precision Equipment

This knurled aluminum thread ring is precision fabricated on CNC lathe from 6061 aluminum alloy. It is designed with vertical straight knurling on outer surface for easy manual twisting and complete internal thread for locking and position adjustment.
The workpiece undergoes rough turning, finish threading, knurling processing, facing and deburring before high-gloss natural clear anodizing, delivering mirror-like bright silver appearance with improved corrosion resistance.
We operate as an experienced OEM custom manufacturer, accepting custom service based on customers’ technical drawings or physical samples. Various dimension, thread specification and surface finishing options can be customized to match different precision assembly requirements. Widely adopted as aluminum lock ring and optical lens adjustment ring in multiple precision optoelectronic and mechanical assemblies.

• Optical equipment, optical lens assembly, lens focus adjustment structure
• Precision instrumentation & measuring equipment
• Photographic equipment and imaging accessories
• Automation small mechanical adjustment assemblies
• Electronic equipment locking and positioning components
• Laboratory precision testing fixtures

We provide full one-stop OEM custom service for CNC machined aluminum parts:

1. Custom production according to customer technical drawings or physical samples
2. Adjustable outer diameter, length, inner bore & internal thread specifications
3. Multiple knurling patterns available upon request
4. Optional surface treatments: different color anodizing, polishing, sandblasting
5. Flexible minimum order quantity for prototype trial & mass production
6. Custom packaging and labeling service

We are a professional custom manufacturer specializing in CNC turning precision metal accessories.

• Inconsistent thread precision? Our threads are processed by CNC finish turning and inspected with thread go/no-go gauges to avoid assembly failure.
• Loose slipping during manual adjustment? Uniform vertical knurling delivers reliable friction for effortless twisting positioning.
• Dull, uneven surface look after finishing? High-gloss controlled anodizing ensures consistent mirror bright silver appearance for high-end equipment.
• Unable to find suppliers supporting small-batch prototype customization? We offer flexible OEM custom service for both prototype trial and bulk orders.
• Unstable dimensional accuracy causing assembly gap? Strict CNC machining tolerance control guarantees interchangeability of parts.

1. Raw material inspection for 6061 aluminum bar before production.
2. In-process dimension sampling inspection during CNC turning, threading and knurling.
3. Full deburring & ultrasonic cleaning to remove residual aluminum chips.
4. Thread 100% check via go/no-go thread gauge.
5. Final full inspection including dimensional tolerance, surface finish, appearance check.
6. Batch quality report available upon customer request.

• 1. Can you make custom size knurled aluminum thread ring other than standard dimensions?
  Yes, we provide full OEM custom service, accept processing per your drawings or samples.
• 2. What tolerance can you achieve for CNC turned aluminum lock ring?
  Normal tolerance ±0.03mm, tighter tolerance can be arranged for special precision demands.
• 3. What other surface treatments are available besides natural silver anodizing?
  We support colored anodizing, bead blasting, mechanical polishing and other aluminum surface finishes.
• 4. Is sample order available before mass production?
  Yes, prototype samples can be produced for your assembly testing.
• 5. How long is the lead time for custom CNC machined aluminum parts?
  Sample lead time around 7–12 working days; mass production lead time depends on order quantity.
