Metal Magic manufactures a series of compact CNC mills. 3 and 4 axis machines with and without tool changers are available. The Metal Magic compact mills are a high performance CNC mill designed for precise machining of Electrodes , Engraving dies, Jewelry patterns and more.

Our compact mills offer rugged industrial construction that ensures smooth machining with tolerances that are very high, with accuracy at .0003" and repeatability at .0001".

These machines are at the top of the precision engraving markets, and compete with high end machines.

          Available sizes:
Series 12 - 12" X 12" X 6" travel
Series 18 - 18" X 18" X 12" travel
Series 24 - 24" X 24" X 12" travel

Choice of manual tool change or automatic tool change, the ATC is a 12 position carousel unit that is fully enclosed and has automatic doors

Spindle speeds up to 100,000 rpm. A typical engraving machine with ATC will have a brushless, variable speed spindle that is liquid cooled and runs up to 60,000 rpm. Manual tool change machines are typically supplied with 42,000 rpm or 50,000 rpm spindles. We also offer slower speed spindles up to 5 HP.

Depending on the spindle configuration, the machines can engrave tool steel dies in complex surfaces, graphite electrodes in complex surfaces, or metals as hard as aluminum at normal machining speeds (i.e. .050 deep at 30 - 50" per minute).
    

Optional 4th axis rotary table. The Centroid 4 axis CNC control provides interpolated machining on all 4 axes. The machine can simultaneously move any combination of axes in conjunction with the rotary table and provides a real time position readout of the rotary table in degrees. Intricate patterns can be machined on any cylindrical object.

Most customers use the machines in production applications and find they run reliably in multi-shift operations.

Other applications they are involved in include medical, electronic, modeling and prototyping, EDM electrodes, deburring, jewelry molds, and many others.

The combination of the fast, precise carriages with the advanced features of the Centroid control enable the machines to produce parts extremely rapidly, and usually much more rapidly than machining centers and other, larger machines. "High Throughput Machining".

The EDM series of Metal Magic compact mills are equipped with Laser certified high precision ball screws and 60,000 rpm variable spindles which provide fast material removal with a extremely fine finish and no chipping.  The mho compact mill machines both graphite and copper electrodes.  The EDM series mills are fully enclosed and equipped with a dust removal system.  The plenum and laminar flow system captures both chips and dust.
