Read our blog introducing Lenchor full-service CNC machining solutions. We cover custom milling, turning, rapid prototyping, low-volume production and secondary surface treatments. Find guides on our workflow, quality inspection and one-stop manufacturing service for custom precision components.
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

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

Why CNC Machining Dominates 2026’s Manufacturing Landscape 1.1 The Core Role of CNC Machining in Modern Industrial Production As we advance into 2026, the manufacturing industry undergoes profound transformation, with CNC (Computer Numerical Control) machining at its core. This indispensable technology drives high-precision component production across diverse high-tech sectors. CNC machining uses pre-programmed software to

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,
When “The Price is Too High” Actually Means “We Didn’t See This Coming” At Lenchor Precision, we’ve reviewed thousands of machining quotes and heard the same frustration repeatedly: “How did this simple part become so expensive?” What most customers don’t realize is that CNC machining quotes aren’t mysterious—they’re predictable. The difference between a budget-friendly quote
The Hidden Truth: Your Design Decisions Directly Determine Machining Costs At Lenchor Precision, we’ve analyzed thousands of CAD files and found a consistent pattern: up to 40% of CNC machining costs are determined by design choices that have nothing to do with part function. These “silent cost drivers” are often invisible to engineers but painfully obvious
