CNC Machining Services
with Shapeways
CNC machining continues to stand the test of time for manufacturers, offering undeniable power in industrial production. With the ability to manufacture thousands of parts in mass production without deviation in quality or detail, CNC manufacturing is often the most proficient route for satisfying customer project requirements–especially on the larger scale.
The Rise in CNC Machining Services
The rise in demand for CNC machining services continues to accelerate too, with ‘impressive growth’ noted currently and projected through 2029. Recent data shows the CNC Machine market valued at USD $64.47 billion, and expected to reach USD $154.02 by 2029–reflecting a CAGR of 10.70% during that time. Lathe machines are specifically in the highest demand for CNC machining applications.
“The primary reasons driving the industry include technological improvements in machine tools, such as robotic and multi-axis arms, as well as the growth in the manufacturing industry,” states Grand View Research.
CNC machining assures manufactures of excellence in product quality, while also offering greater speed and efficiency. While demand increases from industrial businesses, there is increased interest in CNC machining due to more economical cost in starting up, more streamlined setup processes than before, and the ability to produce in small or larger volumes. Automation is expected to become even more critical to this process, as well as more sophisticated–offering even greater benefits to a wide range of industries in the future.
What is CNC Machining?
In comparison to additive manufacturing or 3D printing, CNC machining is known as a subtractive process. Pre-programmed computer software controls machining, issuing instructions centered around a 3D file. CNC technology offers outstanding dimensional accuracy in parts, using a variety of automated tools and machines for fine-tuned precision, to include:
-
- Cutters – Machine tools constructed of metal materials like steel, CNC laser cutters consist of a head, lens, and nozzle. The cutter chips away at a block of material until the intended structure is complete and accurate. Cutters may also be used to mark or engrave parts or make customized shapes.
- Drills – Several drill types are used for CNC machining, employing a rotating cutting tool to create extremely precise openings for screws and bolts. Holes may be drilled into parts for other purposes too, including aesthetics. CNC drills are used with a wide range of materials and are known to be very accurate due to computer control.
- Grinders – These abrasive grinding machines finish parts for surface quality, while removing minimal material. These tools are accompanied by a rotating grinding wheel that moves in place for subtracting material from a part. CNC grinders may be categorized as surface grinders, centerless grinders, cylindrical grinders, internal grinders, or other parts. They are also used to sharpen CNC tools, especially cutters.
- Lathes – As mounted, stationary machines, lathes rotate materials on a spindle, ensuring manufacturing of precise shapes in CNC machining. Lathes are not just traditional tools–they harken back to ancient times where two people would use the tool to make simple woodwork. Since times like Ancient Egypt, the lathe has evolved into a modern, precision tool directed by software code.
“Milling machining is a common production process used in machine shops and industries to create high-precision products and parts in a wide range of forms and sizes. The need for milling machines is predicted to increase due to benefits, such as reduced human errors, exact cuts, high precision, and the ability to make individual components in small or big batches,” states Grand View.
These automated CNC manufacturing tools can also be added to with other choices like hydraulic vises as well as parts like probes allowing for more efficient setup. Automated coolers are helpful for long production runs, as well as side-mount tool changers for storing parts and switching to other tools.
The History of CNC Manufacturing Technology
Parsons’ work was built upon by engineers, evolving from punched tape used for telecommunications and data storage into digitally controlled machining using countless forms of material. Along with this machinery, CAD software evolved into the powerful technology we know today.
CNC Machining Applications
Typical industries relying on CNC production for parts include:
- Aerospace
- Automotive
- Construction
- Electronics
- Marine
- Medical and dental
- Oil and gas
- Transportation
The Benefits of Traditional Manufacturing like CNC Technology
Today, many businesses rely on hybrid technology. This means using a mixture of AM processes and CNC machining. For companies requiring versatility, hybrid technology can be the answer to retaining all the benefits possible, with AM complementing traditional manufacturing.
One of the greatest benefits of CNC machining is that it is compatible with so many different types of materials. Shapeways offers a range of materials for use with CNC machining, some of which are used in additive manufacturing, like thermoplastics, nylons, and metals.
While designers and engineers must consider tolerances to heat, design requirements and guidelines, stress resistance and more, our User Application team can always assist in answering additional questions as well as helping with more complex projects or customizations.
