Design Guidelines

Threads and fasteners are critical functional features in CNC machined components. They are widely used to assemble parts, secure structural connections, and enable modular product design across a wide range of industrial applications.However, improper thread design can significantly increase machin

This CNC tolerances design guide explains how to specify machining tolerances clearly, avoid over-tolerancing, and reduce unnecessary manufacturing cost. Learn how standard CNC tolerances, tight tolerance features, hole fits, milling geometry, wall thickness, internal corner radius, GD&T, material selection, and 5-axis machining affect part accuracy and production cost. NAITE TECH shares supplier-side engineering insights to help designers apply tight tolerances only where they are functionally required.

Surface finish is an important design requirement for CNC machined parts. It affects not only how a part looks, but also how it performs in assembly, sealing, sliding, wear resistance, coating adhesion, corrosion resistance, and long-term reliability. A surface that looks acceptable may not be suita

Designing holes for CNC machined parts involves much more than simply defining a diameter in a CAD model. Hole size, depth, location, tolerance requirements, and threading specifications can all influence machining efficiency, production cost, and final part quality.Whether creating simple through h

In CNC machining, internal corner radius is one of the most frequently overlooked design features. While sharp internal corners may appear ideal in CAD models, they are often difficult, expensive, or even impossible to produce efficiently using standard CNC cutting tools.Understanding how internal c

Designing appropriate wall thickness is a critical factor in CNC machining. It directly affects part rigidity, machining stability, dimensional accuracy, and overall production cost.In general, recommended CNC wall thickness depends on material type and part geometry. For most metal parts such as al
