Destiny Tool Viper Outperforms the "Name Brand" End Mill

2/18/2015

0 Comments

 
Mechanized Numerics, a machine shop located in Ann Arbor Michigan ran a a comparative test with our Viper End Mill against a "name brand" tool.  We think you'll like the results. We certainly do!
We've been saying this for many years: You can rough AND finish with the same end mill!!

"A demonstration example of slotting between two supposedly "high performance" aluminum-cutting endmills. The cutter and parameters shown here are IDENTICAL. However, the cutting is not excessive and one of the tools vastly outperformed the other.

The proper endmill shown is a Destiny Tool Viper (V33224S). The other endmill is from a different high-end name brand that we formally used with some success in the past, though we no longer use them."
  • Tool size: 1/2 inch diameter; 1.5 inch flute length, 3 inch overall length.
  • The same toolholder and collet were used with both.
  • Identical endmill projection for both (distance to gauge line was 4.6 inches)
  • Identical endmill extension for both (2.25 inch length from collet nut).
  • Spindle speed: 12kRPM
  • Feedrate: 0.004 inch-per-tooth (144 inches/minute)
  • Axial depth of cut: 0.210 inches.
  • The aluminum material had a thickness of slightly under 1.25 inches total

"The only real difference between the two cutters was their coating; the Viper was stealth coated while the other was ZrN coated. (not that it should make a difference at this conservative feedrate)"

"I have nothing to gain by posting this clip. I just want to show people the ridiculous sound from supercharging an endmill that can't be supercharged under these conditions. It's by no means a scientific test, but still evident of the problems encountered with certain tools floating around the industry, and the way it *should* be with a proper cutting tool."
Mechanized Numerics specializes in small production work in aluminum, intricate 3d features, complex surfacing, or otherwise unorthodox workpieces.
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.
