As we continue our journey in CNC machining export business, today we want to talk about one frequently asked surface finishing option: black oxide, commonly known as blackening. The part shown here is a large CNC-machined steel cylindrical tube with multiple perforated holes and fine groove features, finished with black oxide treatment. When communicating with […]
1. Raw Material Is Non-Magnetic, But Machined Parts Are Magnetic? Many customers test AISI 321 bar stock with a magnet and find no magnetism. But after CNC milling or turning, the finished part attracts a magnet slightly. Does this mean the material is defective? The answer is: It is normal, and it is not a

Introduction In precision CNC aluminum machining, anodizing is the most widely‑used surface finishing process for aluminum components, commonly applied to medical‑device assemblies, instrument housings and precision structural parts. Many mechanical engineers encounter a subtle yet troublesome problem: threads pass go‑no‑go gauge testing perfectly right after CNC machining, yet some threaded holes fail the no‑go gauge

In the fast-paced world of product development, the ability to quickly transform an idea into a physical part can make or break your timeline. When it comes to rapid prototyping and small-batch production, two technologies dominate the conversation: 3D printing and CNC machining. While both can produce high-quality parts, they operate on fundamentally different principles—one builds layer by layer, while the other
In the world of precision manufacturing, choosing the right CNC machining partner can feel like a high-stakes gamble. When quotes arrive, it’s tempting to let the decision be driven by two simple factors: price and delivery lead time. After all, these are tangible, easy to compare, and directly impact your bottom line and project schedule. However, experienced procurement

Introduction: The “Curse” That Keeps Countless Engineers Awake at Night “The prototype tested perfectly—why do problems keep emerging once we move to mass production?”“The client was very satisfied with the first batch of samples, but formal orders always get stuck due to quality fluctuations.”“The design was verified in small batches—why does everything fall apart when
In the realm of modern surgery, the evolution from open procedures to minimally invasive surgery (MIS) represents a quantum leap. At the heart of this revolution are endoscopes and surgical robots—devices that grant surgeons “eyes and hands” deep inside the human body with minimal trauma. Their performance, however, hinges on an often-overlooked foundation: the exquisitely
When Every Gram Matters: The Weight-Performance Equation in Drone Manufacturing As drone technology evolves from hobbyist toys to industrial tools and delivery systems, manufacturers face an increasingly critical challenge: how to make structures stronger while making them lighter. At Lenchor Precision, we’ve worked with drone companies on everything from consumer quadcopters to industrial inspection drones,
