One of the most well-made CNC routers, ideal for cutting tougher woods and metals like aluminum.
What are CNC Mills?
CNC mills are a type of computer numerical control machine that cut, shape, and engrave materials like wood and metals. Milling is the process of using rotary cutters to remove material from a workpiece. The milling cutter is held by a spindle and can cut in different angles as it moves along the different axes.
CNC mills can range from 2-axis machines up to 5-axis mills. The number of axes defines how they cut. For example, a 2-axis machine can only cut vertically and horizontally, whereas a 5-axis CNC mill can cut complex shapes for uses such as in prosthetics and other medical applications, and car models.
CNC mills differ from manually controlled mills in that they’re operated using a computer. The computer number control is a programmed code that relays instructions for precise movements to be carried out by the mill. The control software converts the numerical code into Cartesian coordinates which allows mills to work with extreme precision.
CNC Mills are used across a huge range of industries, from simple carpentry to automotive and aerospace design.
What are CNC Mills Used For?
CNC mills can cut and engrave a wide variety of materials, from wood to metals like titanium. They are mostly used by businesses for manufacturing products, though many hobbyists also use them for home CNC projects.
Because of their versatility, CNC milling machines can help with applications like:
How Much Do CNC Mills Cost?
Entry-level CNC mills start at around $2,000 and then go up to +$40,000 for more advanced mills.
However, included in this price is the machine as well as the control software used for the machine. More expensive CNC mills operate at an industrial level and will include advanced features like automatic tool changing and more axes.
Those looking to use a CNC mill at home are best sticking to the entry-level machines, like the TAIG we have listed, or going with a CNC router if you want to save a couple of bucks.
CNC Mills vs CNC Routers
To the untrained eye, CNC mills and CNC routers may appear very similar. While they both do have similar functionalities, there are several key differences. In fact, if you want to buy a cheap CNC machine, your only options really are to buy a router, as low-cost CNC mills start in the several thousand dollar price ranges.
Arguably the most important difference is that CNC milling machines are designed to cut and engrave extremely strong materials like metal with ease.
CNC routers are best for softer materials like plastics, acrylics, wood and aluminum, while CNC mills are capable of cutting much tougher materials such as steel and titanium.
CNC routers use stationary workpieces and spindles that move in X, Y, and Z. In contrast, CNC milling machines use parts that move in X and Y and spindles that move in Z. The difference in axis motion means that CNC mills have increased clearance along the Z axis, allowing them to perform thicker cuts of tougher materials.
Most mills also have spindles that are slower but have more torque than those used in routers, which primarily rely on rotational speed for cutting. This higher torque — the force that causes objects to rotate around axes — provides more power to cut harder materials.
Whereas most routers use a gantry frame design, CNC mills typically use a C-frame structure with a column and base. The C-frame structure helps make mills more robust so they can handle harder materials than CNC routers.
CNC routers are typically mounted upon stationary work tables and usually have a larger workspace than mills.
CNC Mill Price
The price for CNC mills and routers varies a lot depending on the type of machine you’re buying. However, on the whole, CNC mills are generally more expensive than CNC routers of comparable quality — even mini CNC mills command a higher price tag.
Low-cost, benchtop CNC routers are much more common than cheap, small CNC mills.
One of the main limitations of CNC mills is their price. It’s rare to find a CNC mill that costs less than $5,000, but that’s cheap when it comes to these machines – the best ones used in industry cost tens of thousands of dollars.
Keep that in mind while we look at some more affordable CNC routers later on. While these won’t offer the same speed or accuracy as highly advanced industrial CNC mills, they’re a great choice for hobbyists who can’t afford to splash out huge amounts.
Tips for High End CNC Machines
There are many premium CNC mills out there, such as the UMC-500 by Haas, one of the leading manufacturers of industrial CNC machines.
The first thing you’ll notice is that this is a 5 axis router. 5 axis machining is much more advanced than the standard 3 axis machining seen in most hobbyist machines. It adds two rotational axes in addition to the standard Y, X, and Z-axis, meaning it can machine parts with significantly higher precision and flexibility. 5 axis mills like this are used to process highly complex products, such as aircraft parts and even military weapons.
You can use 30 different tools with this machine and it can mill even the hardest metals like steel, unlike hobbyist machines which are restricted to aluminum.
Of course, as this is a CNC machine, highly technical designs can be created beforehand, simulated, and then fed to the machine which will process workpieces accordingly with little to no manual intervention needed.
Haas and other distributors of this machine don’t even advertise the price – you have to get in touch for a quote – but you can be sure it’ll set you back tens of thousands.
CNC Mills FAQs
What is a CNC mill operator?
A CNC mill operator is someone who sets up, operates, and tends to the milling machine. They work on a range of tasks including, but not excluded to:
– Removing workpieces from the machine
– Quality checking workpieces
– Loading materials onto the machine
– Observing the operations
– Managing cutting speeds, cutting depths, feed rates, and applying shop mathematics
– Studying and crafting workpiece blueprints
What are the different types of CNC mills?
When it comes to CNC mills, there are two main types – vertical and horizontal.
Vertical CNC mills use a vertical machining center (VMC) to sport a vertically-orientated spindle that holds and rotates the cutting tool against the stationary workpiece. The spindle moves up and down while pushing into the workpiece in order to remove excess material.
These typically have thinner, longer cutting tools and provide great visibility so you can supervise how the cut is progressing.
Vertical machines are best for plunge work, small parts, short series, and precision parts.
There are a further two types of CNC vertical mills: turret milling machines and bed milling machines.
The main difference between these two styles is how the parts move.
With a turret machine, the spindle and bed move perpendicular and parallel to the axis, while bed milling machines only move the table perpendicular to the axis. Because of this, most companies prefer turret machines as they hold the bulk of the versatility.
Turret machines work best with small projects and excel with milling precise small parts. Alternatively, the bed machine’s rigidness and larger frame make it ideal for milling bigger parts.
Horizontal CNC mills, as you might expect, possess a horizontal machining center (HMC) and a spindle that holds the cutting tools horizontally instead of vertically.
Horizontal tools are shorter and thicker and are used to make deeper, heavier cuts than vertical tools. Horizontal mills were actually created first, and it was through the creation of attachments and modifications that the vertical mill came about.
Horizontal CNC mills work best for long material work, like cutting gears and cutting grooves and slots into workpieces. It’s meant to work for heavier materials and pieces.
