Five major factors affecting the quenching deformation of parts

Quenching is often called steel’s “coming-of-age ceremony”—the leap that grants metal its essential hardness. But this process always carries a major risk: deformation. Deformation isn’t a mysterious occurrence; it is the direct result of the interaction among thermal, structural, and... Read More

Don’t mess with chamfering threaded holes; doing it wrong will cause jamming and damage to parts.

Who hasn’t casually marked “1×45°” for chamfered threaded holes on their drawings? Machining technicians have probably done it too! But you might not know that this seemingly “harmless” little mark can easily lead to assembly jams, thread scratches, and loose connect... Read More

Three-axis or five-axis? A comprehensive guide from manufacturing processes to costs.

In the workshop, you can often hear young engineers muttering, “Why can some machining centers mill complex impellers, while others can only do simple tasks like planing and drilling?” The answer is actually quite simple—the key lies in the number of axes! The axes of a machine tool a... Read More
