What Is Arbor CNC Milling?
Arbor CNC milling uses a special rod (called an arbor) to hold cutting tools. The arbor spins fast while a computer controls how it moves. This helps make perfect cuts in metal, plastic, and other materials.
What makes it special? We can put multiple tools on one arbor! This means you can do rough cuts and smooth finishing all at once. It’s like having many workers doing different jobs at the same time.
How It Works
When we use CNC milling services, the machine follows a computer program to make precise cuts. With arbor milling, the cutting happens on a horizontal setup instead of a vertical one.
Here’s how it works:
- The arbor(metal rod) holds one or more cutting tools
- The machine spins the arbor very fast (up to 15,000 RPM)
- The computer moves either the tool or the material being cut
- Coolantsprays on the cutting area to keep things from getting too hot
This setup is perfect for making parts with flat surfaces and deep pockets.
Types of Arbors
Arbor Type | Details | Best Used For | Speed Range |
MT1, MT2, MT3 | Morse taper connection | Small to medium jobs | 5,000-10,000 RPM |
R8 Taper | Common in many mills | General purpose work | 8,000-12,000 RPM |
ISO 40/50 | Industrial standard | Heavy-duty production | 8,000-15,000 RPM |
HSK63 | Quick-change system | High-speed machining | 10,000-15,000 RPM |
The right arbor type depends on what we are making and how big your part is. At Istar Machining, we help you pick the best setup for your project.
Benefits of Arbor CNC Milling
Why choose arbor milling over other types? Here are the big benefits:
- Faster Production: Cut material 30% fasterthan with vertical mills
- Better Finish: Makes smoother surfaces with less tool marks
- Longer Tool Life: Tools last longer because of better chip removal
- More Stable: Less vibration means more precise parts
- Multiple Operations: Can do roughing and finishing in one setup
One of our customers made helicopter rotor hubs and cut their production time in half by switching to arbor milling!
Technical Specs of Arbor CNC Milling
- Work Size: Most machines handle parts up to 40″ x 20″ x 25″
- Spindle Power: 15-50 HP motors for different materials
- Coolant System: High-pressure (200+ PSI) for better chip evacuation
- Control System: Fanuc, Siemens, or Haas computer controls
- Tool Changing: Automatic systems for non-stop production
Our 5-axis machining centers combine these features with multi-directional movement for complex parts.

Arbor vs. Other Milling Methods
How does arbor milling compare to other types?
- Vertical Milling: Arbor milling removes material 30% fasterand is better for large, flat surfaces
- End Milling: Can use multiple cutters at once instead of just one
- Face Milling: Better for long, continuous cuts across wide areas
At Istar Machining, we offer both vertical milling and arbor milling to handle any type of project.
Reasons for getting the best results
We follow these tips so we can get the best results from arbor CNC milling:
- Use Climb Milling: Cut in the same direction as the spindle rotation when possible
- Match Feed to Speed: Find the right balance of cutting speed and feed rate
- Check Arbor Alignment: Make sure everything is straight before starting
- Use Proper Coolant: Keep tools cool for longer life and better finishes
- Secure Workpieces Firmly: Prevent movement during cutting

Frequently Asked Question
The key difference is that arbor CNC milling uses a horizontal rod (arbor) that can hold multiple cutting tools simultaneously. This often allows for faster material removal, especially on wide, flat surfaces, compared to typical vertical milling which usually uses one tool at a time in a vertical orientation.
Arbor milling can be faster primarily because multiple cutting tools can be mounted on the same arbor, allowing different operations (like roughing and finishing) or wider cuts to happen in a single pass. This setup is also very stable, permitting more aggressive cutting speeds and feeds, leading to up to 30% faster production compared to some vertical milling methods.
This method is particularly well-suited for parts requiring large flat surfaces, deep pockets, or grooves. It’s commonly used for components in industries like aerospace (engine parts), automotive (transmission housings, engine blocks), medical (implant molds), and energy (turbine components).
