Micromachining End Mill Handles Materials as Hard as 65 Rc

Expanding the Jabro range of solid carbide end mills, Seco’s JM100 Mini is designed for shops struggling to machine micro-size workpieces with adequate surface finish, accuracy and precision.

Expanding the Jabro range of solid carbide end mills, Seco’s JM100 Mini is designed for shops struggling to machine micro-size workpieces with adequate surface finish, accuracy and precision. Intended for use in micromachining operations with zero visibility of workpiece and cutting tool, the JM100 Mini is said to provide longer tool life, stability and good surface quality because of precise tool geometries, almost zero runout, advanced coatings and tight radius tolerances.

Engineered to achieve precise surface finishes on mold and die components and able to machine tool steel as hard as 48 to 65 Rc, the JM100 Mini thus helps shops minimize secondary benchwork that can increase part processing time. The end mill’s coating reduces tool wear to help lower overall tool costs and eliminate the need for frequent tool changes. Tight radius tolerances of ±0.005 micron on the tool reduce runout virtually to zero, increasing output and contributing to lower cost per part with high process precision, stability and reliability.

The JM100 Mini is available in diameters ranging from 0.2 to 3.0 mm (0.008" to 0.118"), corner radii ranging from 0.05 to 0.3 mm (0.002" to 0.012"), and overhang lengths ranging from 1.5×D to 20×D, with two and three-flute versions.
