CNC Machining

What is Precision CNC Machining? CNC (Computer Numerical Control) machining is the world's most precise subtractive manufacturing process. Pre-programmed software (G-code / M-code) dictates every movement of cutting tools — speed, feed rate, depth, coordinate — removing material layer by layer from a solid metal block until a custom-designed part emerges with ±0.01mm tolerance. At HY-HK, our core CNC technology spans 3-axis to 5-axis simultaneous machining on Mazak, Brother, and other premium platforms. We process 304/316L stainless steel, titanium alloy (Ti-6Al-4V), aluminum, copper, brass, Inconel, tungsten, and PEEK — from single prototypes to 100,000-piece production runs. Our proprietary core technology ensures every part meets AS9100 / ISO 13485 / IATF 16949 standards. And because it's under the HY-HK roof, every CNC-machined part can be seamlessly passed to our PVD coating line — one factory, one quality standard, zero handoff.

Technical Principle

How It Works — From Digital File to Metal Part in 5 Steps:

① CAD Design: Your part is designed in 3D CAD software (SolidWorks, UG, CATIA, etc.) — every curve, every hole, every tolerance defined digitally.

② CAM Programming: The CAD model is converted into toolpaths using CAM software — selecting the right tool, speed, feed, and strategy for each feature. The output is G-code — the language CNC machines understand.

③ Setup & Fixturing: The raw metal block (blank) is secured in the machine vise or custom fixture. Tool offsets are calibrated. Zero-point is set.

④ Machining: The CNC machine executes the G-code — spindle spins at up to 20,000 RPM, tools move along X/Y/Z (and A/B for 5-axis) axes, removing material layer by layer. Our core technology uses real-time thermal compensation and in-process monitoring to maintain ±0.01mm throughout.

⑤ Inspection & Delivery: Every part is inspected by CMM (Coordinate Measuring Machine) — verified against the original CAD model — then packaged for assembly or surface treatment.
