"A brief video showing a 3d roughing operation on these extender brackets. The previous tools couldn't handle the full-depth cut length unlike these Destiny Tool Diamondback roughers. The operation now takes half as much time, and the total part time was reduced by over 10%.
1/2" diameter 3 flute flat Diamondback roughing endmill, 10,000-RPM, 140-IPM (must avoid pulling the parts from their fixture!).
3/8" diameter 2 flute spherical Diamondback roughing endmill, 10,000-RPM, 96-IPM.
Not shown in the video, the finishing operation is done using a 3/8" diameter 2 flute spherical Viper endmill running 0.003-IPT at 12,000-RPM with a 0.020" stepover."
Mechanized Numerics (MNL) was formed in 2009 in effort to expand the fabrication abilities of contract work being done for the fluid power industry. In the months that followed, the machine shop was expanded to encompass additional manufacturing for new projects and markets. A secondary goal of the business was to provide unique design options for automation technologies used in workcell and process development activities.
In 2011 they created a subdivision called Nummech which is meant to specifically support non-industrial products and services. Through this brand they sell a number of parts and equipment made for camera components, paintball accessories, vehicle parts, lighting accessories, and others. They provide OEM products for several companies looking to maintain a foothold in US-based production.
