Inverted Machining Centers - Next generation machine tools

MODIG is turning the industry upside down. The next generation of machining has begun.

With this world’s first inverted machining center, MODIG is transforming the way we will think about generic five-axis part and component machining. MODIG’s inverted machining centers are setting a new standard for machining. The industry has been waiting for the next shift in performance after the CNC-machines debut during the ’60s and horizontal machining centers in the ’80s. Inverted machining means a new way of performance with the spindle machining from below.


Tomorrow’s Technology Today

Thinking new is not new to MODIG, its a continuation of MODIG’s decade long technological leadership positioning and trend setting machine tool designs. So, let us think inverted!

 “Let’s think new.
Let’s think inverted!”

– David Modig, President Modig Machine Tool

What is inverted machining?

The short answer would be that an inverted machining center is a vertical machining center turned upside down. An inverted machining center is, in other words, a machine processing from below. But the question has a more complex answer as inverted machining is an entirely new revolutionary manufacturing method when it comes to machining.

Increased demand for higher and higher tolerance

Today everything from the body of a smartphone to an airplane is manufactured by machining. The complexity of these products and components is continually increasing. Traditional manufacturing methods for these products use vertical milling machines with a tool machining from above over a work piece or horizontal milling machines where the device is working from the side. But there is an increasing demand for higher and higher tolerance. For matching these requests, there is a need for enhanced solutions.

The MODIG way

To meet the increasing need for improved machining solutions with higher speed and precision and improved handling of removed material, MODIG needed to think outside the box. After many simulations, it turned out that when the cutting tool was working from below, it was possible to remove chips from the work piece effectively. Further, the design allows for a more stable machine, which results in improved speed and precision.

The inverted machining center with all the advantages it encompasses over traditional processing methods was born. This is available with single or multi-spindle options.


How rigid is an inverted machine?

In today’s production we strive for even tighter tolerances and better precision, and that requires stable and reliable processes. Based on this, MODIG created the inverted machining centers.

With technical ingenuity and the ability to meet our customers’ needs, MODIG has built a stable machine with a cast iron base around the structure. A construction that makes the machine extremely rigid and extremely fast. As well as a reduced footprint.

“Rigid, inverted, think upside down!”

The engineers at MODIG have managed to separate the forces that occurred from the trunnion table’s vertical movement from the spindle’s horizontal directions to make the machine more stable. Doing this has reduced the side to side forces so that it does not affect performance and the machine work with best-in-class precision.

Optimal chip handling with inverted machining centers

How to build a machine with an optimal chip handling system?

This question has been a million dollar question for machine builders through history. By turning the machining industry upside down, introducing inverted machining centers, MODIG is as close you can come to optimal chip handling today. Working inverted means easier chip evacuation with less consumption of coolant. The gravity makes the chips fall with a natural flow from the work piece and the working area.

Inverted machining innovation turns the industry upside down

For many machined components there has been a problem with vertical and horizontal machining centers where chips filling up the work piece’s pockets and, after a while, the whole working area. Even if a horizontal approach creates more natural chip removal, the solution has not been perfect. Before operators had to stop the machine for manual removal of chips. With inverted machining centers, MODIG has set a new standard for chip handling.
