Our best estimate for a sinker edm (ram edm) in this class — not a quote from GF Machining Solutions. Configuration moves it a long way.

Overview

The Form 3000 is a very large sinker EDM listed with 1,000 x 800 x 500 mm of travel, a work tank of approximately 1,500 x 1,000 mm and a 5,000 kg workpiece limit. GF Machining Solutions does not list it in its current range, and the figures here are the listed ones, not checked against a GF source.

The listed control is an AC CNC with the iGEN4 adaptive generator, rated at 64A peak discharge current. The table gives two finish figures: Ra 0.4 to 0.8 under standard finishing, and Ra 0.1 micron under mirror conditions. On mould bases of this size most of the surface is finished in the standard range, with mirror conditions kept for the visible cavity areas.

At approximately 30,000 kg listed machine weight, buying one used means planning a foundation, heavy transport and installation before anything else. Dielectric can be kerosene-type oil or deionized water according to the table, with integrated filtration.

Strengths & Limitations

Strengths

1,000 x 800 x 500 mm of travel over a tank of approximately 1,500 x 1,000 mm
Listed workpiece capacity of 5,000 kg
Listed mirror finish of Ra 0.1 micron, with Ra 0.4 to 0.8 under standard finishing

Limitations

Approximately 30,000 kg machine weight makes relocation a major project
64A peak discharge current is modest for roughing the large electrode areas this envelope allows

Best For

Large mould bases and die blocks up to 5,000 kg Cavities spread over a 1,000 x 800 mm area Mirror finishing on large visible surfaces

Frequently Asked Questions

01 How big a workpiece does the Form 3000 take?

The listed travel is 1,000 x 800 x 500 mm, the work tank is approximately 1,500 x 1,000 mm and workpieces can weigh up to 5,000 kg. Blocks larger than the travel can sit in the tank, but only the area the axes reach can be eroded.

02 What does it take to move a used Form 3000?

The listed machine weight is approximately 30,000 kg before dielectric. That calls for a foundation survey, heavy transport and rigging, and confirmation of which dielectric, oil or deionized water, the machine was set up for.
