5 Tips for Finding the Right CNC Mill

CNC Milling toolThere are a lot of new and used CNC machines on the market, but some of them are no bargains. While it might not take much to fix up an old wreck that’s been milling for the last three decades, that “great deal” on the showroom floor could end up forcing you to do more repairs than milling. And that brand-spanking new machine? It’s a hefty investment, so you have to be careful with that option, too.

Generally, you should approach buying a used CNC mill with the same caution you’d have when buying a used car—kick the tires, take it for a spin and look under the hood. The same goes for a new one. If the sales rep tells you that it was gently used every Sunday by a little old lady from Pasadena, put a hand on your wallet and back away slowly. Before you lay out the cash, check out these tips for getting an affordable CNC mill that won’t let you down.

What size CNC machine will you need?

The answer to this question will depend on a couple of factors. First, you need to determine the amount of floor space you can allocate for the new machine and its gear. Next you need to determine the size of the components you’ll be producing, and how to store the raw materials. You may also need to make room for a vented hood, particulate mitigation and even a water-cooling system.

What materials are you machining?

If you’re machining mostly simple parts, you can get by with an older rebuilt or gently-used CNC machine. If your parts are more complex, however, or you need more axes to produce your parts, then you would probably be better off with a newer, more versatile machine.

What are your maintenance costs?

If you’re currently paying for frequent maintenance and repairs on the machine you have now, you may want to consider buying a newer machine. Just like a car, a CNC mill requires maintenance, but at some point it can become more cost-effective to invest in a new machine rather than try to keep an old machine on life support.

Is the manufacturer still in business?

Are replacement parts still readily available for your old CNC mill? If not, buying a newer but lightly-used machine could be your best bet. Custom-machining replacement parts for a discontinued model from a company that is no longer in business could end up costing you as much as the brand new machine you thought you couldn’t afford.

What are your productivity needs?

If business is booming and you want to use a CNC machine to speed up production, you would do well to look at new models. Newer machines are generally more capable than older models, so if time is of the essence, you will do better with a more up-to-date station.

Before you commit to a purchase, you might want to ask the seller if you can “test drive” the machine. If you’re not very experienced with CNC machines, bring an experienced CNC machinist with you to evaluate the machine’s performance and condition. Ending up with a lemon on the shop floor could cost you time, money and even customers. It’s worth taking your time to find the right machine that will save you cash and aggravation down the road.

CNC Milling Allowed Apple to Create the World’s Thinnest Laptop

MacBookA decade ago, Steve Jobs unveiled the MacBook Air in a clever on-stage demonstration by removing the two-pound laptop from a flat manila envelope. At just .76 inches at its thickest point, it was the thinnest laptop ever created. The MacBook Air challenged preconceived notions about industrial design, and ushered in a whole new era of ultra-slim laptops that seem to defy the limits of their hardware.

Now, ten years after consumers first laid eyes on the MacBook Air, Apple is reportedly preparing to retire the laptop from its product lineup. That’s why we’d like to take a moment to highlight the contribution CNC milling made to the original design of the world’s thinnest laptop.

In 2008, Apple’s designers were working to develop new manufacturing techniques that could streamline the process of creating unibody aluminum products. At the time the company was using CNC machines to design product prototypes, but not to mass-produce its final products.

In an effort to make the MacBook Air a reality, Apple began investing heavily in its CNC infrastructure so that it could be scaled-up for mass production.

Since then, Apple has begun using CNC mills to mass-produce other products like iPhones and MacBook Pros as well. These sleek, seamless aluminum bodies have become a trademark of Apple’s design aesthetic, and it’s all thanks to the power and precision of CNC machining. In recent years, other laptop manufactures like Acer and Asus have even adopted Apple’s methodology to create their own super-skinny “Ultrabook” PCs.

The MacBook Air may be nearing the end of its lifespan, but the CNC processes that made the innovative laptop possible are still having a profound effect on today’s consumer electronics.

What a CNC Mill Turn a Block of Aluminum Into a Cylinder Head

What a CNC Mill Turn a Block of Aluminum Into a Cylinder HeadCNC machines are the industrial sculptors of the modern era. There’s something downright mesmerizing about watching a CNC mill transform a blank piece of material into a complex piece of functional equipment.

Take the video below, for example, where a massive 5-axis CNC machine effortlessly mills a cylinder head out of a solid block of aluminum.

It’s a powerful tool with a light touch, shaving of fractions of a centimeter at a time to achieve a degree of precision that human machinists can only dream of. Thanks to the machine’s 5-axis design, the cutting tool is able to approach the raw material from just about any angle. In just under three minutes, you can watch a hunk of metal become the heart of an internal combustion engine.

A Vertical Milling Machine Can Save Space in Your Shop

Although there are many different CNC mills on the market, they typically fall into two broad categories—vertical CNC machines and horizontal CNC machines. Another, less common type of CNC machine is the universal CNC machine, which converts from a vertical mill to a horizontal mill, offering the best qualities of both types of machine in one convenient package.

The most common type of milling machine is the vertical machine because it takes up less floor space.

This type of machine utilizes a spindle that comes down from the top of the machine, making it much taller than it is long or wide. As a result, many hobbyists and business owners prefer to use a taller vertical machine instead of a horizontal one, which may take up too much valuable floor space in their shops. If you’ve been hesitant to invest in a CNC machine in the past due to space constraints, a vertical mill is a great option to consider.

Take the SUPRA CNC vertical knee mill, for example.

This vertical CNC mill offers a small footprint and highly functional design that is ideal for both beginners and experienced CNC operators. It also comes equipped with our own Master MX software that makes it easy to execute complex commands and create highly-detailed designs.

Factors that Affect CNC Milling Quality

Factors That Affect CNC Milling QualityThanks to their ability to execute complex instructions and fabricate products to precise specifications, CNC mills can be incredibly useful tools to have around. But just because you finally got your hands on a CNC mill doesn’t mean you’ll be able to press ‘Go’ and start machining engine blocks right away.

Ultimately, the quality of your finished product will depend on a few different factors.

There are two main factors that control the results of CNC milling: Hardware and software.

These factors determine the capability of the milling machine and, consequently, the quality of work that can be produced. It is important that the software and hardware of a CNC machine should complement one another. At CNC Masters, we include our own custom CNC Master MX software package with each of our CNC mills.


A typical mill is composed of four axes or pivot points that animate the machine head. These pivots make it possible for the machine to rotate, turn, and work on surfaces that are at difficult angles with the head. The more axes in a machine, the more flexible and versatile it will be.


Software, on the other hand, is what drives the axes for precision machining; this is the brain of the machine.

CNC stands for computer numerical control, a set of alphanumeric commands that operators can enter into the software’s user interface.

  • These commands are then translated into a computer language called G-Code.
  • Each code corresponds to a precise action that the machine can interpret and execute in sequence to achieve a desired end result.
  • A complex project might utilize thousands of these G-Codes, each of which constitutes one small step in the manufacturing process.

CNC Machining Vs. 3D Printing

CNC Machining Vs. 3D Printing


CNC Machining and 3D printing methods are two forms of object manufacturing that draw a lot of comparisons, although they operate very different from each other. For example, CNC machining is programmed to manufacture an object by carving a material to a desired object shape, while 3D printing builds an object via layers.

While both printing methods are very different, we have outlined some advantages and disadvantages for CNC Machining and 3D printing.

Under CNC Machining (or CNC milling), a customized computer program is created for the manufacturing of an object, while accurately controlling several factors such as feed rate, location, coordination and speeds. Using CNC programming the computer program better controls exact positioning which ultimately leads to the highest standard of accuracy. Not only is CNC Machining precise, it is also very easy for repetitive manufacturing while also maintaining accuracy.

Another perk to CNC Machining is how it can work with a large variety of materials such as plastic, metal, wood and wax as well as several others.

CNC machining is faster than 3D printing. CNC machining creates an object by cutting away material to create an object, while 3D printing works by reducing an object via tiny layers until it creates the shape of an object. The process of 3D printing can’t be sped up, so when it comes to manufacturing speed CNC milling has the upper hand.

CNC milling has a higher level of quality settings. When you’re in the prototype stage, sometimes it’s nice to complete a task with speed rather than accuracy to speed up the development phase of a project, which is a big benefit to CNC milling.

With 3D printing, one must endure the slow production of a product layer by layer, which really slows down the prototype research and development phase.

Another downside to 3D printing is that it requires a larger workforce to design operate and maintain product production. Couple this with the higher setup costs, and 3D printing becomes inferior to CNC Machining.
