HC Series

The versatile Roku-Roku HC Series hybrid VMC performs high-speed graphite milling, hard milling, small-hole drilling and micro milling.

The HC Series eliminates the need for two high-end vertical milling machines—saving both money and floor space.

With an innovative high-rigidity, bridge-type monoblock structure, the Roku-Roku HC Series is painstakingly built by hand to the absolute highest standards.

Schedule a demo today to see this dual-purpose powerhouse that’s accurate, fast, reliable, durable and exceedingly versatile.

HC Series

ENGINEERED FOR ACCURACY

  • The HC Series is designed to deliver industry-leading accuracy, reliability and consistency.
  • Advanced dust collection and prevention technologies make graphite milling less prone to defects and errors.
  • The unique monoblock casting keeps the entire machine rigid.

ONE INVESTMENT, TWICE THE FUNCTIONALITY

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

FLEXIBLE, FUTURE-FRIENDLY DESIGN

  • 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.

CAPABILITIES:

  • Hard-milling and graphite-milling capabilities
  • 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

  • "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."
