Value Added CNC Machining Services

Heat Treatments

The heat treatment process increases the hardness, strength and durability of  CNC machined components. Depending on the grade to which the component is heat treated, additional benefits can include improved integrity, machineability and corrosion resistance.

Destructive and Non-Destructive Testing

Destructive and Non-destructive testing (NDT) determine how a component will behave under pressure until failure. NDT examines a component for defects and discontinuities without damaging the original part.

Metal Plating/Finishing

Finishing alters the surface of a workpiece and prepares it for bonding, plating or painting.


The exact type of welding process and machine required, Mig, Tig or Plasma Arc, depends on the material being machined and final product design. Welding provides an added degree of precision for intricate CNC components.

Sinker and Wire EDM

Our operators can use innovative Sinker and Wire EDM to create complex, highly accurate tooling and intricate shapes.


Grinding refines the surface finishes of finalized CNC components. This can involve tampering, stepping, grooving, profiling, chamfering and more to either create a better finish or prepare a component for additional finishing services.


Honing improves or corrects the diameter, shape, surface finish and tolerances of a machined component.

Sheet Metal

There are many different ways that we can fabricate sheet metal to meet your application requirements. Popular sheet metal fabrication services include:

  • Cutting
  • Punching
  • Forming
  • Holemaking
  • Stamping
  • Threading


Taking a CNC machined component to a fully-assembled product streamlines manufacturing to save on time and costs.

Swiss Machining

Miller CNC can fulfill Swiss CNC machining requirements for smaller, intricate parts that require extreme accuracy.
