Who says desktop CNCs are only for wood?
Today, I’m putting the HiMill D1S to the ultimate test! For this 2026 Perpetual Calendar project, I boldly experimented with a hybrid material design: a "Walnut backplate + Aluminum alloy slider."
The fusion of cold, industrial metal with the warmth of natural wood turned out beautifully—the final product looks like a high-end designer piece. Want to know how to stably cut aluminum on a desktop machine? This guide is all you need!
🛠️ Project Overview
- Project Name 2026 Wood & Aluminum Industrial Perpetual Calendar
- Equipment HiMill D1S Desktop CNC
- Core Challenge Aluminum cutting (rigidity & cooling test)
- Key Features Minimalist style, Brushed texture, Everlasting
- Main Materials Walnut & 3mm 6061 Aluminum Alloy
📋 1. Preparation
Since we are dealing with "hard-on-hard" machining, material selection and tooling are critical.
Hardware Materials (BOM)
- Aluminum Sheet: 6061 Aluminum is highly recommended (excellent machinability, less "gummy"), 3mm thickness.
- Wood: A dark hardwood like Walnut is ideal to contrast the silver sheen of the aluminum.
- Cooling/Lubricant: Alcohol spray bottle or cutting fluid is mandatory to prevent material welding to the bit.
Recommended Tooling (Aluminum Specific)
Never use a standard 2-flute straight bit for aluminum—it will snap!
- The Secret Weapon: Single Flute Spiral End Mill.
- Why: It provides a large chip clearance area, allowing aluminum chips to be ejected rapidly. Recommended diameter: 3.175mm or 2mm.
- Wood Engraving: Laser module.
💻 2. CAM Programming Strategy
Machining aluminum is entirely different from wood. The golden rule is: "Slow feed, thin passes."
Step 2.1 Aluminum Slider Settings
To ensure a mirror-like finish on the edges, use these conservative parameters:
- Spindle Speed: 13,000 RPM
- Feed Rate: 200 mm/min
- Step Down: 0.1mm - 0.2mm (CRITICAL!)
Step 2.2 Tolerance Fit
Unlike wood, aluminum has zero elasticity. The fit must be exact. In the design phase, I applied a -0.1mm negative tolerance to the aluminum slider.
⚙️ 3. CNC Machining Process
The HiMill D1S’s time to shine!
- Wood Processing: Easily handle the digital engraving and outer contour of the Walnut backplate.
-
Aluminum Processing (The Main Event):
- Clamping: Secure the sheet tightly using pressure plates and double-sided tape.
- Lubrication: Spray alcohol every few dozen seconds during the cut.
- Observation: The Z-axis of the HiMill D1S remains rock steady, producing holes with perfect circularity.
🎨 4. Post-Processing: The Brushed Look
- Deburring: Use a deburring tool or fine file to remove sharp aluminum slivers.
- Brushed Finish: Rub the surface repeatedly in a single horizontal direction using a Scotch-Brite pad or 400-grit sandpaper. This creates that high-end "MacBook" texture.
- Oiling: Apply wood wax oil to the Walnut to deepen its tone and bring out the grain.
🧩 5. Assembly & Summary
When the silver brushed aluminum is embedded into the deep walnut grooves, the contrast is stunning. The slider moves smoothly, and the circles align perfectly with the numbers.
Summary: This project proves that the HiMill D1S is fully capable of light metal fabrication. With the right parameters, you can create professional-grade metal crafts at home!
