CNC Machining

Introduction to CNC Speeds and Feeds Calculations Whether you are a design engineer specifying tolerances or a CNC machinist standing in front of a 5-axis mill, mastering Speeds and Feeds is mandatory. Guessing these numbers leads to shattered endmills, melted workpieces, and horrific surface finishes. At 3Q Machining, our CAM programmers calculate precise cutting parameters […]

Introduction to Drill Bit Sizes and Tap Drill Calculations Whether you are a design engineer detailing a CAD model or a CNC machinist standing at the control panel, selecting the correct drill bit size is the foundation of precision manufacturing. At 3Q Machining, we know that a simple “Drill Size Chart” isn’t enough. The most

Introduction to Reducing CNC Machining Costs Whether you are prototyping a single component or planning a high-volume production run, CNC machining offers unparalleled precision. However, it is an inherently subtractive process—meaning machining time equals money. At 3Q Machining, we regularly receive RFQs (Requests for Quote) featuring designs that are needlessly expensive to manufacture. By applying

Introduction to CNC Machining Burrs and Deburring In the world of metal cutting, burrs are public enemy number one. A burr is an unwanted raised edge or small piece of material that remains attached to a workpiece after a machining process like milling, drilling, or turning. Left untreated, burrs ruin part assembly, cause severe cuts

✓ Technical Fact-Checked | Expert technical review by Mose Li | Application: Aerospace & Medical Tooling Introduction to Choosing CNC Tool Holders If you visit any professional machining forum like Practical Machinist, you will quickly learn a fundamental truth: You can buy the most expensive carbide endmill in the world, but if you put it
