CNC Milling

CNC Milling

Computer Numerically Controlled (CNC) Milling

The milling technique means the material typically is stationary and the tooling rotates to remove the excess material and create the unique shape and characteristics. The design is specified on a computer using CAD (Computer Aided Design) tools to instruct the machine tool as to the profile and shape of the design. This capability allows for complex parts to have extremely high quality and very responsive delivery lead-times because of high repeatability.

In Tolerance uses both Hurco and Mazak technology programmed, set-up, and operated by CNC machinists with an average of 20 years of experience. Our machining centers offer up to 18,000 rpm, 120 station tool holders, and conversational PC based controls networked to a centralized repository housing both programming and set-up files to ensure tight process control.


In Tolerance operates:

  • 7 Mazak CNC Vertical Mills with maximum size of 16x20x12, holding a .001 tolerance.
  • 5 Mazak Horizontal Mills with maximum part size of 16x16x16, holding a .001 tolerance.
  • 3 VM-1 Hurco Mills with maximum part size of 16x20x12, holding a .001 tolerance.
