EMI’s Advanced Cutting-Tool Technologies

RotanTM – Rotary-Insert Cutting Tools

(U.S. Patents Pending; E.U. Patent Pending)
EMI-developed Rotan rotary tangential-mount technology brings all the benefits of a rotating insert into perfect alignment with semi-finish and finish machining. All the benefits of rotary-insert machining — continuous indexing of the full circumference of the insert’s cutting edge, no potential for notch wear, management of heat, and smart use of the large insert radius — plus application strategy and special tooling hardware enhancements that produce fine finish with no visual artifacts of insert rotation. Rotary-insert machining can provide up to 90% reduction in cycle time and projected increases in tool life (servicing interval) of 50x or more.


(U.S. Patents Issued)
EMI’s Micro-Quantity Internal Cooling (MQuIC™) technology offers extended tool life in finish-machining of difficult-to-machine materials. MQuIC™ technology addresses thermally induced wear by concentrating a cooling medium close to the process heat source.

Micro-Jet Array

(U.S. Patent Issued)
EMI’s Micro-Jet Array (MJA) precision-cooling technology is derivative of the MQuIC™ concept, except that the coolant is applied at micro-scale via jets originating external to the insert rather than from within the insert.

EMI Technologies on the Horizon


(U.S. Patent Issued)
EMI’s ThikCoat™ technology, having recently completed the
commercial feasibility stage under a Phase-I SBIR project, addresses abrasive wear by creating a
significantly thicker hard coating on a substrate than is traditionally possible.

Universal Chip Breaking:

Currently in the technical feasibility stage, EMI’s Universal Chip Breaking (UCB) technology offers a single cutting insert geometry for all cutting classes (rough, medium, finish).


(U.S. Patent Issued)
Applications include vehicular storage for hydrogen- and CNG-based transportation and oxygen/air storage for home medical oxygen patients…
