What is Vertical Milling?
Vertical milling is a type of machining where the cutting tool moves up and down, with its axis pointing straight down into the material. The tool spins fast while moving across the work surface to cut away material and make precise shapes.
At Istar Machining, we use vertical milling to create parts with amazing accuracy. The main part of a vertical mill is the spindle – that’s what holds and spins the cutting tool.
Key Features and Benefits
Here’s why shops big and small love vertical milling machines:
- High-Speed Cutting: Our spindles run at 8,000-15,000 RPM, letting us cut through aluminum like butter!
- Amazing Accuracy: We can make parts within ±0.001″ (about the thickness of a human hair)
- See Everything: The vertical setup lets operators watch the cutting as it happens
- Space-Saving Design: These machines take up less shop floor space than horizontal mills
- Cost-Effective: Lower upfront costs make vertical mills great for getting started
As one of our machine operators says: “With vertical mills, what you see is what you get – there’s no guessing what’s happening under the cutter.”
Comparing Vertical vs Horizontal Milling
Not sure which type is right for your project? Check out this simple comparison:| Feature | Vertical Milling | Horizontal Milling |
| Tool Position | Points down at workpiece | Points across workpiece |
| Best For | Flat surfaces, pockets, drilling | Heavy material removal, slots |
| Visibility | Excellent – see cutting action | Limited – tool may be hidden |
| Setup Time | Faster for simple jobs | Longer setup but faster for big jobs |
| Floor Space | Compact (6’x4′) | Larger (8’x6′) |
| Learning Curve | Easier for beginners | Steeper learning curve |
Materials You Can Machine
Vertical mills are amazing at working with many different materials:
Real-World Applications
Our customers use vertical milling for all kinds of cool projects:
Aerospace
We make lightweight parts for planes using high-speed spindles that can reach 30,000 RPM for aluminum CNC machining. The surface finish is so smooth it looks like a mirror!
Medical Industry
Our vertical mills create surgical tools with tolerances of ±0.0005". That's five ten-thousandths of an inch - crazy precise!
Automotive Parts
Engine blocks need many precise holes and flat surfaces. Vertical mills make this work easy and accurate.
Jewelry Making
Custom designs in brass and steel with amazing detail are possible with micro-tooling on vertical mills.
Education and Training
Schools love vertical mills because they're easier to learn on and students can see exactly what's happening during the cut.
Why Choose Vertical Milling?
Vertical milling machines offer the perfect blend of precision, versatility, and value. They can handle so many different jobs.
Whether you’re creating prototypes, making small production runs, or crafting one-of-a-kind parts, a vertical mill delivers the accuracy you need without breaking the bank.

Frequently Asked Question
Yes! With the right carbide tools and proper speeds, vertical mills can work with hardened steel up to Rockwell 60C hardness.
Bed mills have a fixed column and moving table, while turret mills allow the head to move for more flexibility.
Absolutely! Vertical mills can create amazing wood projects, though dedicated CNC wood machining equipment might be better for very large projects.
Yes! In fact, vertical mills excel at drilling operations because of their up-and-down motion.
