MAXMAKE HiMill D1S Feeds & Speeds Guide: Aluminum, Acrylic, Wood & PCB
Achieving professional-grade results on a desktop machine like the MAXMAKE HiMill D1S isn't magic—it’s about mastering your Feeds and Speeds.
Are you struggling with broken bits, melted edges, or "chatter" marks on your CNC projects? In this comprehensive technical guide, we break down the tested parameters and tooling choices for the four most popular materials in desktop manufacturing.
1. CNC Aluminum Machining: Mirror Finish & Zero Clogging
Aluminum is the ultimate test for any desktop CNC router. The key challenge is preventing the metal from sticking to the bit, a phenomenon known as chip welding.
Recommended Tooling
- 3-Flute Tungsten Carbide End Mill: Offers superior rigidity to prevent tool deflection while maintaining enough flute space for efficient chip clearing.
Core Parameters (HiMill D1S)
- Spindle Speed: 12,000 - 13,000 RPM
- Feed Rate (XY): 100 - 200 mm/min
- Stepdown (Ap): 0.1 - 0.3 mm
Always use a cutting lubricant (like WD-40 or specialized cutting fluid) along with a strong air blast. This prevents the bit from "re-cutting" chips, which ruins surface finish and snaps tools.
2. CNC Acrylic Cutting: Melt-Free, Crystal-Clear Edges
To avoid melted, gooey edges and micro-cracks in acrylic CNC projects, you require high feed rates and a razor-sharp cutting edge.
Recommended Tooling
- Single Flute Spiral End Mill: Single flute designs feature a massive chip gullet, allowing them to carry heat away from the cutting zone much faster.
Core Parameters (HiMill D1S)
- Spindle Speed: 10,000 - 13,000 RPM
- Feed Rate (XY): 600 - 800 mm/min (High speed prevents heat buildup)
- Stepdown (Ap): 0.5 - 1.0 mm
If the acrylic starts to melt or turn white (frosting), immediately increase your feed rate or decrease your spindle speed. Keep the tool moving!
3. Machining Tooling Board & Pattern Wood
For high-detail models, prototypes, and molds, tooling board (pattern wood) is the go-to material. It machines beautifully with very low resistance.
Recommended Tooling
- 2-Flute Solid Carbide Flat / Ball Nose End Mill: Perfect for smooth 3D relief carving and rapid material removal.
Core Parameters (HiMill D1S)
- Spindle Speed: 12,000 - 13,000 RPM
- Feed Rate (XY): 1,000 mm/min
- Stepdown (Ap): 1.0 - 3.0 mm (Material resistance is low)
Utilize the D1S’s built-in magnetic brush or your workshop vacuum during machining. This prevents ultra-fine dust from settling on the lead screws, ensuring long-term machine precision.
4. Precision PCB Engraving: Micron-Level Accuracy
The MAXMAKE HiMill D1S excels at in-house PCB prototyping, largely thanks to its rigid structure and ±0.02mm repeatability.
Recommended Tooling
- Corn Teeth End Mill (PCB Router Bit): Specially designed for composite materials, leaving sharp traces without delamination.
Core Parameters (HiMill D1S)
- Spindle Speed: 12,000 - 13,000 RPM
- Feed Rate (XY): 800 - 1,000 mm/min
- Stepdown (Ap): 0.05 - 0.2 mm
Surface Mapping: Always use the Auto-leveling feature. By electrically probing the surface of your copper-clad board before cutting, the software compensates for microscopic warping, ensuring a consistent 0.05mm engraving depth.
