Every part we produce in our CNC turning center is under the close supervision of a team of CNC machinists, who are dedicated to creating the best products within a timeframe and budget that fits your project needs.

CNC Turning Capabilities

Our CNC turning center equipment has a precision measurement of plus/minus .0005” or better, producing parts with higher quality than ever before. Offering a “DONE IN ONE” machining process, our ISO 9001 certified machinery is capable of working with many different materials, ranging from more malleable materials such as aluminum and brass to more complex materials such as steel, stainless steel, titanium alloys and high nickel alloys and can provide a variety of finishing processes. Our high precision turning equipment includes:

  • Haas ST-10 Mill/Turn Center with Bar Feeder (Max Barfed Bar Diameter @ 1-3/4”)
  • Mori Seiki SL204SMC Main/Sub Mill/Turn Center with Bar Feeder (Max Barfed Bar Diameter @ 2-9/16”)
  • Hardinge Talent 51 Turn/Mill Center with Bar Feeder (Max Barfed Bar Diameter @ 2″)

The new generation of Haas turning centers specialize in being extremely rigid, highly accurate and very thermally stable. The ST-10 model includes rugged 2 axis lathes, dual-spindle, super speed and Y-axis models for producing parts that are sure to outperform anything in their class.

How it Works

When you contact M&M Automatic Products requesting a quote, we will set up a consultation to review your product needs and design a plan based on your timeframe and budget. We can even help you design your parts and determine what would be the best raw materials to use to produce them. Our CNC milling machinist will then manufacture your parts and will have them shipped and into your hands on-time and on-schedule. We’re even capable of producing your parts on an expedited timeframe if needed!

What is CNC Turning?

Turning is one of the oldest methods for shaping pieces. Originally, this was done by hand, but the addition of computer controls has made turning faster, more efficient, and more precise. CNC stands for Computer Numerical Control and it refers to the computerized control system that controls the turning machine. A CNC turning machine uses a spinning lathe and cutting tools to shape a piece of stock, usually metal, and sometimes wood, plastic, or other materials.

What is the difference between CNC Turning and CNC Milling?

CNC turning and CNC milling are similar processes, and are often included in a single category under CNC machining. Both of these are considered subtractive processes, meaning they remove material from a piece of stock in order to create a shape. In general, CNC milling is used for more complicated or intricate parts, while CNC milling is used for creating simpler cylindrical or oblong parts, like shafts. The other significant difference between CNC turning and CNC milling is the way the machines operate; turning rotates the stock against the cutting tools while milling rotates cutting tools against the workpiece.

What is CNC Turning used for?

Though there are many types of CNC turning lathes, each with a variety of capabilities, CNC turning is generally used for less complex parts compared to CNC milling. Because of the way CNC turning operates, it’s ideal for shaping cylindrical parts, such as shafts, tubes, knobs, some crankshafts, disc cams and similar components.

What materials do CNC turning machines use?

CNC turning machines often use many of the same materials as CNC milling machines. Usually, CNC turning machines use round bar stock, while CNC milling machines use square or rectangular bar stock. Both machines can work with many different metals and alloys, including aluminum, brass, steel, titanium, and nickel, as well as some types of plastic.

How close are your CNC turning machine tolerances?

Our CNC turning center operates at a tolerance of plus/minus .0002”

What is a typical run for a CNC turning machine?

CNC turning is generally best for prototypes and short runs between 10 and 1,000 pieces.
