Makino’s EDGE2 Sinker EDM With Fine-Hole Option

Advanced Technology and Superior Quality Ideal For Micromachining

AUBURN HILLS, MI—September 2008—Plastic injection mold builders, aerospace and forging die job shops that want to begin performing fine-hole electrical discharge machining (EDM) can now rely on an advanced, high quality EDM solution. Makino’s EDGE2 Sinker EDM machine with fine-hole option achieves maximum micromachining performance with superior surface finishes.

EDGE2 Features
The EDGE2 with fine-hole option features 12 x 10 x 10 inch travels and weighs a sturdy 6,000 pounds. The machine bed is a heavily ribbed, single piece casting. Anti-friction linear guides and bearings complete the high-performance design, combining excellent rigidity with low-mass dynamics. This heavy-duty construction, combined with the fixed table, brings high levels of rigidity to every application.

Makino's award-winning drop tank design and dielectric chiller completes these features. The drop tank improves many aspects of the EDM process, as the retractable tank walls provide wide-open table access for safe, simple slide-on loading and faster, more accurate setups. The adjustable tank depth allows matching of dielectric fluid level to workpiece size.

Standard Features Promote Unattended Operation
The EDGE2 with fine-hole option is further enhanced by an array of Makino's standard EDM
features, including:

  • an eight- or 16-station automatic electrode changer for unattended operation and improved throughput.
  • An MA rotating head capable of standard 10 to 1,000 rpm rotation. 
  • High performance Z-axis spindle capable of up to 400-in./min. high speed jump. 
  • An automatic fire extinguisher to protect the operators, workpiece and machine. 
  • A fixed table that eliminates dielectric weight shift during machining and improves servo reaction speed and precision. 
  • Fine-Hole machining option capable of automatically changing 0.0039-inch diameter x 12-inch long pipe electrodes from the ATC unit. 
  • Fine-Hole machining option capable of utilizing 0.0012” diameter electrodes.
  • Special electrode dressing operations permit automatic dressing routines to produce electrode to as small as 0.00024” diameter.
