2025-05-21
From medical implants to aerospace components, extremely precise parts are the key to keeping some of most critical aspects of our modern world running smoothly.
Manufacturing these small, complex parts efficiently, and within demanding tolerances, requires the right state-of-the-art equipment paired with the engineering skills to exploit it.
Increasingly such parts are manufactured in a single set-up using mill/turn machinery.
This blog is intending to explain how a mill/turn works, how a mill/turn is used in high precision parts manufacturing, and the many benefits of the mill/turn’s combined functionality.
What Is a Mill/Turn Machine?
A mill/turn machine is a hybrid CNC (computer numerical control) machine that combines both milling (tool rotating) and turning (workpiece rotating) functionalities into one fast, powerful, and flexible machine that can complete complex operations faster and with greater accuracy than traditional machining technologies.
While other machines perform a single function, mill/turn machines can accomplish up to four operations at the same time.

Benefits of Mill/Turn Machines
2025-05-21
Mill/turn machines are a newer technology, and because of that, they are less common in machine shops compared to traditional milling and turning machines. However, combined mill/turn technology enables a wide variety of benefits compared to traditional machines, including:
Ability to machine more complex parts
Mill/turn machines are able to create more complex and intricate parts without needing to transfer the part from one machine to another. This opens a world of possibilities. Use of this equipment can enable UK manufacturers to take on more complex and higher precision jobs and produce the parts more competitively. Parts that many would perhaps have previously either turned away, or been unable to produce efficiently.
Faster operations
Because a mill/turn can complete 4 operations at the same time, the total time needed to create each part is significantly reduced. In addition to machining the parts faster, mill/turns can also be set up more quickly than other machines. Most of this time savings is because raw material only needs to be set up once to perform all the different operations, without requiring the part to be adjusted or moved to another machine after each operation.
Higher accuracy
Because a mill/turn can complete 4 operations at the same time, the total time needed to create each part is significantly reduced. In addition to machining the parts faster, mill/turns can also be set up more quickly than other machines. Most of this time savings is because raw material only needs to be set up once to perform all the different operations, without requiring the part to be adjusted or moved to another machine after each operation.
Automation of menial tasks
Since most mill/turn machines are newer, they offer more built-in automation than traditional machining equipment. Tasks like loading material, probing, and removing parts are done automatically, freeing up the machinist’s time to do other more interesting and value-added activities.
Using mill/turn machines to combine operations, means less machinery – or less floor-space. Fewer machines in turn means reduced operators. It also means less power and compressed air is consumed. All of these reductions combine to deliver cost savings and improve profitability.
As the advances in user-friendly CAD/CAM packages with Mill/turn platforms and post-processors, mean it is also much more accessible and no-longer just the preserve of large tier one specialists.
And with more machine tool manufacturers beginning to produce Mill/turn technology so it becomes more commonplace and more affordable than you might think.
The benefits of this technology is increasingly being harnessed by forward thinking sub-contractors, looking for a competitive edge.

What's the difference between CNC milling and CNC turning?

What are CNC Mills and CNC Lathe Machines?
Milling and Lathe Turning are fundamentally similar processes that use subtractive manufacturing to create the desired output. However, they differ in process. While CNC milling involves holding the source block of material steady while the tools move to cut it into shape, the CNC lathe process involves holding the tools steady while the block is moved to get the desired output. Let us understand the difference between CNC Mills and CNC Lathes in detail.
Difference between CNC Lathe and CNC Milling
We all have used duct tape or at least seen someone use it. If you need a piece of tape, you can pull out as much as you need, hold it steady, and use a pair of scissors to cut at the desired length. On the other hand, you can use a duct tape cutter where you pull the tape up to the desired length and then tug at it sharply for a stationary blade to cut through. This is the simplest way to explain the difference between a CNC Lathe and CNC Mill. The primary difference between a CNC Milling Process and CNC Lathe Process is the way the part and machine rotate.
CNC Lathe – rotates the part or material against fixed cutting/shaping tools
CNC Mill – keep the material stationary and rotate the cutting/shaping tools around it
While the difference is subtle, it allows them to create specific objects. A CNC Conventional Lathe is good for creating objects that are symmetrical and uniform across a cylindrical or conical surface. Some examples are knobs, disc cams, crankshafts, screws, etc. CNC Milling helps create flat surfaces, create pockets and grooves, and drill deep holes across a wide range of objects.
Which One Should You Opt For?
CNC Mills and CNC Manufacturing Lathes are ideal for different outputs. Hence, to choose the right option for your needs, it is important to consider your requirements and analyze the design carefully. Phillips Machine Tools offers a range of tools to help you leverage the power of CNC Machining into your operations. For Milling and Lathe Turning machines, we have partnered with one of the top industry leaders in CNC Manufacturing. HAAS CNC. We also offer CNC machine pairing with additive manufacturing tools and robotics and provide training to help users use these machines to their utmost capacities.
Conclusion
While CNC Milling machines offer a wider range of tools for cutting and shaping, CNC Lathes are ideal for cylindrical objects. Make sure that you assess your production needs and choose one accordingly.
