How Do You Define CNC Part Appearance Standards?
Defining clear appearance standards for CNC parts is a collaborative process that prevents subjective quality disputes. The goal is to establish objective, measurable, and documented visual acceptance criteria before production begins. This process starts with specifying critical cosmetic attributes on your technical drawings. Key parameters include maximum allowable scratch sizes, locations of acceptable tooling marks, […]
How to Ensure Authentic 7075 Material Standards?
Ensuring your 7075 aluminum is genuine and meets specifications is critical for high-performance applications. The most reliable method for material verification involves a multi-step quality assurance process. First, always source from reputable suppliers who can provide a detailed Material Test Report (MTR) or Certificate of Conformance (CoC). This document certifies the alloy’s chemical composition and […]
Why Do Lines Appear on Anodized 7075 Aluminum?
Material lines on 7075 aluminum after CNC machining and anodizing are most often caused by alloy segregation within the raw material itself. 7075 is a high-strength alloy containing zinc, magnesium, and copper. During the aluminum’s manufacturing, these elements can distribute unevenly on a microscopic level. While invisible on raw or machined aluminum, the anodizing process […]
Can CNC Parts Get a #180 Sandblast Anodized Finish?
Yes, applying a #180 grit sandblasted and anodized finish to CNC machined aluminum parts is a very common and highly effective manufacturing process. This multi-step procedure is ideal for achieving a high-quality, uniform appearance. The workflow begins after the part is machined via CNC. The part then undergoes sandblasting with #180 grit abrasive media. This […]
