Precision CNC Turning for Prototypes & Production

At Ranglink, we provide high‑quality CNC turning services for custom metal and plastic parts. Whether you need a single prototype or a medium‑batch production run, our modern lathes and skilled machinists deliver tight tolerances, fast lead times, and reliable quality.

We specialize in rotational parts – shafts, bushings, threaded components, discs, and custom cylindrical geometries. No minimum order quantity. ISO 9001 certified.

What is CNC Turning? – Ranglink

What is CNC Turning?

CNC turning is a machining process where the workpiece rotates at high speed while a stationary cutting tool removes material. It is ideal for creating cylindrical or round parts – shafts, bushings, threaded rods, discs, and custom rotational components.

Unlike CNC milling (which uses rotating tools to cut a stationary block), turning is best for axisymmetric shapes. With live tooling, we can also mill, drill, and tap off‑center features in one setup.

✅ Typical parts: shafts, sleeves, pulleys, flanges, threaded fittings.

Available Materials for CNC Turning

CNC turning works with a wide range of materials – metals (aluminum, steel, brass, copper), plastics (acrylic, nylon, ABS), composites (carbon fiber, fiberglass), and even foams. Machinability depends on factors like hardness and thermal conductivity. Below are the materials we commonly use for CNC turning at Ranglink.

FAQ – CNC Turning | Ranglink

Frequently Asked Questions (FAQ)

Everything you need to know about our CNC turning services

What is the difference between CNC turning and CNC milling? ▼

CNC turning rotates the workpiece while a stationary tool cuts it – ideal for cylindrical parts like shafts and bushings. CNC milling rotates the tool while the workpiece stays stationary – best for complex 3D shapes like housings and molds.

Do you offer prototyping for turned parts? ▼

Yes – we specialize in fast prototyping. Minimum order is one piece. Typical lead time for prototypes is 3 business days.

What file formats do you accept for quotes? ▼

We accept STEP (.stp), IGES (.igs), STL, SolidWorks (.sldprt), and PDF drawings. STEP files are preferred for best accuracy.

Can you machine complex geometries on a lathe? ▼

With live tooling and multi‑axis capabilities, we can perform off‑center milling, drilling, and tapping in a single setup – reducing lead time and improving accuracy.

What is your quality control process? ▼

We inspect first pieces, then perform in‑process checks and final inspection using calipers, micrometers, height gauges, and CMM. Full inspection reports are available upon request.

Do you sign NDAs? ▼

Absolutely. We treat your designs as confidential and are happy to sign a Non‑Disclosure Agreement before any project discussion.
