5083 Aluminum CNC Turning: Improving Surface Consistency
A 1,000-part order for optical equipment called for consistent tool marks and a bright machined surface. OUJI adjusted the feed and reassessed tool selection to improve the appearance across the batch.

01
The Challenge
The visible surfaces needed an even machining pattern and a bright appearance from part to part. Early production could not meet that requirement reliably, making surface consistency the main obstacle on this order.
02
OUJI's Approach
OUJI optimized the feed and reassessed the cutting-tool selection. These changes addressed how the visible surface was produced during machining and improved the proportion of parts meeting the appearance requirement.
03
The Result
The revised machining approach improved the surface result substantially. Tool-quality variation remained an issue, according to the production team, and the remaining roughly 10% of nonconforming parts were handled through rework.

Project questions
What was the main requirement for these optical-equipment parts?
The 5083 aluminum parts needed consistent tool marks and a bright appearance on their visible machined surfaces. The order quantity was 1,000 parts.
What should an RFQ specify for a similar visible surface?
Mark the appearance-critical faces and include the material grade, quantity and surface treatment. Provide a reference sample or clear criteria for the machining pattern and brightness, and state whether the requirement applies before or after treatment.
