Our MEC-ARC-120 is a new concept of keyseating machine: it is the result of years of experience in the construction of this type of machine. MEC ARC-120 is designed for machining large workpieces with inner and outer notches and grooves of any shape and size.

The ‘arc’ configuration of our MEC ARC range provides an unprecedented working stiffness in this type of machining. MEC ARC-120 has three or four working axes, which are synchronized via an automatic system. The incorporation of a CAM in the system allows our MEC ARC-120 to work with maximum precision when it comes to defining any type of shape, however complex it may be. 

With the MEC ARC series, MECO achieves the highest level of technological capability: customizing, designing, and building the most suitable MEC ARC for each customer’s needs.

Our MEC ARC-120 is a unique and revolutionary keyseating machine that will undoubtedly place us at the forefront of the construction of this type of machine worldwide.
