iMX Exchangeable Head End Mills

The iMX series is a revolutionary end mill system that enables efficiency, high accuracy and rigidity by combining the advantages of both solid carbide and indexable end mills. Security and rigidity close to that of a solid type end mill because the clamping faces are all carbide.Excellent for reduced inventory over a variety of applications due to the exchangeable head.

Smart Miracle (EP7020)Smart Miracle is a newly developed (Al, Cr)N group coating which delivers substantially better wear resistance. The surface of the coating has been given a smoothening treatment resulting in better machined surfaces, reduced cutting resistance and improved chip discharge. This is the next generation of coated end mills that delivers long tool life when machining stainless steel and other difficult-to-cut materials.

Exchangeable head end mills have a cost advantage compared to solid end mills. In a comparison test against a ø10mm corner radius end mill, the iMX type was shown to become more cost effective at the point where a 3rd solid end mill was needed. In addition performance doesn’t deteriorate with iMX, but the re-grinding of solid end mills results in changes of dimension and shorter tool life.

* The above is for reference only. Results may vary depending on the re-grinding tolerance.

*Note 1) Do not handle cutting edges with bare hands.

*Note 2) Please use the wrench provided. It is thinner than a standard wrench to prevent damage to the flutes when tightening.

Before installing the head, thoroughly clean all contact faces.Applying anti seize compound to the thread is recommended, but do not apply to the taper faces.

Use the wrench provided to tighten until there is no clearance between the head and holder end face.

The recommended tightening torque is shown in the table below.

Depth of cut

1) The use of cutting fluid is recommended when machining stainless steels, titanium and heat resistant alloys.2) If the depth of cut is shallow, the revolution and feed rate can be increased.3) The irregular helix flute end mill has a larger effect on controlling vibration when compared to standard end mills. However, if the rigidity of the

machine or the workpiece installation is poor, vibration or abonrmal sound can occur. In this case, please reduce the revolution and feed rate proportionately, or set a lower depth of cut.

4) % is the inclination angle of the machined surface.

Result

The tool reduced machining time by 30% and also produced a good surface finish.

The irregular helix flutes combined with the solid carbide holder gave better performance than the competitors tools.

Machining wi thout v ibrat ion was achieved even when the workpiece radius and tool radius were the same.
