This ElTee Pulsitron TRM-21 Sinker (Ram) EDM is a precision toolroom Ram EDM built around a 16" x 11" work table, a 19.75" x 14.75" x 12" dielectric work tank, and 8" x 6" x 10.5" of X / Y / Z travel — with the Z-axis programmable for repeatable burn cycles. Power is supplied by ElTee Pulsitron's matched EP-300CP 30 Amp power unit, the quill carries up to 100 lbs of electrode (22 lbs with magnetic tooling), and the machine ships with its dielectric / chiller unit, a 3-axis DRO, and a hand cross feed for the toolmaker-style operation Pulsitron machines are known for. Compared to earlier ElTee Pulsitron models like the TRM-10 and the original Pulsitron M-series that relied on simpler analog regulators and lacked any programmable axis, the TRM-21 paired with the EP-300CP brings a programmable Z plus full 30 Amp average-current capacity into a footprint that still fits in a one-machine tool-and-die shop. The result is a sinker EDM that handles graphite or copper electrode burns on production die details, mold cavities, and short-run punch work at a fraction of the cost of a comparable Japanese sinker, with US-based ElTee Pulsitron parts and service still readily available.

About This Machine

Stop fighting an aging analog sinker EDM through every die job — this ElTee Pulsitron TRM-21 brings a programmable Z-axis, a 3-axis DRO, and a matched 30 Amp EP-300CP power supply into a single toolroom-grade Ram EDM with 8" x 6" x 10.5" of travel, a 16" x 11" table, and up to 100 lbs of electrode capacity. Plug it in and your shop can run repeatable cavity and detail burns the same week, with US-based ElTee Pulsitron parts and service still readily available.
