HC Series

These ‘hybrid’ machining centers are built for high-speed graphite milling, hard milling, small hole drilling, and micro milling.

Why purchase two high-end vertical milling machines—one for graphite and another for hard milling—when you can get both from one machine?

Spanning four different models—each with the same high-rigidity, bridge-type “monoblock” structure that allows for high-speed, high-precision machining—the HC series hybrid vertical milling machines combine industry-leading graphite milling with hard milling capabilities.

The result is a dual-purpose VMC solution that’s accurate, fast, reliable, and, best of all, durable—and more than versatile enough to be useful in a wide variety of situations.

HC Series


  • All HC series machines have been designed to deliver industry-leading accuracy, reliably and consistently. From advanced dust collection and prevention technologies that make graphite milling less prone to defects and errors to a unique “monoblock” casting that keeps the entire machine rigid under operation, these machines are the answer for any job that needs to be done right the first time.


  • With access to multiple milling capabilities all in one single machine, you can handle more jobs more economically than ever before. Hard milling? Graphite? The HC series gives you multiple machines in one, increasing production efficiency and reducing your costs overall.


  • Automation is your shop’s ticket to new levels of efficiency and profitability, and the HC series is more than ready to get you there. This machine is highly configurable, allowing you to create the processes you need to get and stay ahead of the game through less costly, more productive operation.


  • Hard milling and graphite milling capabilities through “super hybrid concept” design
  • Enhanced accuracy via a high-rigidity, bridge-type monoblock structure with a minimized distance between the guide surface and spindle center
  • High repeatability thanks to the high-rigidity bed with ideal rib distribution
  • High-speed direct hard milling through dry (or optional semi-dry) oil-mist systems
  • Ideal machine for high-speed milling, drilling, and tapping
  • Wide RPM ranges and long spindle operating lifetime
  • Easy, intuitive programming and operation via on-board CNC controller



  • Highly rigid structure
  • High-rigidity HSK-E25 and HSK-E40 tool holders (6x more clamping power than previous)

  • "Not only does the 5-axis capability of the OPS Ingersoll Eagle V5 milling machine enable us to burn parts with less physical electrodes, it also has a robotic tool changer so we can focus more during the day on things that need constant attention."

    Brad McDowell, Quality Tool & Die president Read case study
  • "The OPS Ingersoll 5-axis milling machines are fast, accurate, easy to operate and have a small footprint."

    Bill Yakle, Owner of Aisling Industries learn more
  • "The Eagle 800 has burn technology that gives us a competitive advantage because it takes about half the time to burn and uses fewer electrodes, which saves both time and money. Our goal is to run it all day and all weekend. I like that we also are cutting down on our carbon footprint by using fewer graphite electrodes and less copper wire than before."

    Steve Michon, President at Zero Tolerance view case study
  • "We used to struggle with tool deflection on deep cuts. Now we’re able to tip that up in a five axis and actually hit on the bottom of the flute. And we’re not getting that tool push anymore. Electrodes are so, so much more accurate."

    Chad Kearns, Quality Tool & Die vice president Read case study
  • "Our biggest supply chain issue is labor, but we have been able to achieve lights-out operation by adding the MC Machinery equipment. We have kept costs down while improving accuracy and doing more with the same number of employees."

    Todd Doerfert, Operations Manager at Mantz Automation learn more
  • "The kinematics of the Roku-Roku VMCs allow us to run faster feed rates and not sacrifice surface finish or accuracy. The machines are efficient in terms of increased cutter life, reliable Fanuc control and overall machine stability. We can run longer intervals on downstream inspection on parts that the Roku-Rokus machined."
