Air Compressors for CNC Machine Shop

CNC Machining Shop Air Compressors

For computer-aided metalworking, a reliable compressed air supply is arguably just as important as the machinery itself. CNC machine tools require compressed air to perform many critical functions needed to meet production targets and satisfy customers. 

Improve your CNC machining capabilities with a compressed air system from Werther International. Whether you need a standard compressor system or a custom solution, we have the knowledge, expertise, and dedication to quality to meet your unique needs. 

Importance Of Compressed Air For CNC Machining 

Put simply, CNC machine tools need compressed air to perform many operations. Examples include:

-Transporting Oil To The Spindle Bearings

-Powering Handheld Tools

-Actuating Tool-Change Mechanisms

-Removing Chips Or Contaminants From Workpieces

The latter is often overlooked, but it’s actually incredibly advantageous. When an automatic tool change occurs, the tool holder shank and the spindle taper become exposed to chips, oil, dirt, and other contaminants in the cutting zone. Any particles stuck to exposed surfaces can reduce machining accuracy and stiffness, and they may even cause permanent damage.

With a reliable supply of compressed air, these issues can be resolved. CNC machine tools can leverage blasts of dry compressed air to keep exposed surfaces clean. 

Trusted CNC Machining Air Compressors

Werther International is an ISO 9001:2015- and 134585-certified provider of silent air compressor systems, oil-less air compressors, nitrogen generators, high-efficiency rotary screw air compressors, and compressed air accessories for CNC machining applications. We understand that a standard or off-the-shelf air compressor may not be best for every facility, which is why our team also provides custom solutions. 

When making the jump to a custom compressed air system, you can rest assured knowing we’re with you from design to delivery. Our experts with your team assess your compressed air needs and technical specifications. Things we look out for include:

  • Budget
  • Condensation
  • Cubic Feet Per Minute, Or CFM, Requirements
  • Noise
  • Electrical Complicity  

It’s important to know the compressor can drive the tools and equipment used in your shop. Condensation is also a key factor to consider during design. Air with undesirable amounts of moisture may condense on workpiece and tooling surfaces, ultimately resulting in corrosion. 

After the assessment, our experts take everything they’ve learned about your application and develop the ideal compressed air equipment design. Upon approval, manufacturing takes place at our facility in Houston, Texas.

With Werther, You Have The Compressed Air Edge

The lifeline of any CNC machining center is its compressed air supply. Age, improper installation or sizing, and unwanted pressure loss can result in a compressor working far harder. This can shorten its working life, waste energy, and increase costs. 

No matter your facility layout, working environment, or budget, Werther International can help you overcome compressed air challenges. Our standard and custom air compressors are relied upon by CNC machine shops small and large to perform various tasks.


  • Lathe Working
  • Milling
  • Cutting
  • Shaping
  • Electronic Discharge Machining, or EDM
  • Plasma Cutting
  • Water Jet Cutting
  • Grinding
  • Painting
  • Chip, Dust, Oil, Dirt, And Contaminant Removal
  • Fluid Recovery Systems


Optimal Air Compressors For CNC Machining 

CNC machining requires highly specialized air compressor equipment to ensure finished products fit, form, and function as intended. 

Our rotary screw air compressors are superb for efficient CNC machining operations, whereas nitrogen generators are perfect for laser-cutting stainless steel or aluminum parts. The nitrogen gas acts as a shielding agent, stopping the burning process and facilitating material vaporization. It also helps remove oxygen from the cutting zone, boosting product quality and preventing oxidation, scaling, and discoloration.

In CNC machine shops, safety is paramount. The silent air compressors we produce can minimize noise, which helps protect employee hearing and create a more enjoyable working environment. 

Let’s Team Up

While it may not seem like it, compressed air plays a pivotal role in CNC machining success. At Werther International, we don’t have a job to do until you do. Therefore, your compressed air challenges become ours, too. 

Powering your equipment should be the easiest part of your job. With our standard or custom CNC machining compressors, it will be.
