Used Small Hole EDM Machines: Start Holes for Wire EDM

Used Small Hole EDM Machines: Start Holes for Wire EDM

wire EDM start holes, small holes in hardened steel, and vent, cooling and injector holes. Where a start hole goes and how big: inside the profile so the slug can drop out, clear of the finished face, and matched to the wire — the machine's 0.25 mm electrode ceiling sits at the fine end of the 0.03–0.3 mm wire range. How the process removes metal: two machine types share the name, and this one uses Sodick's rigid shanked electrodes from 0.08 mm to 0.25 mm, cleared by a retract cycle, so depth follows flushing rather than electrode length. What the published specifications decide: travel, table, workpiece limit, electrode range and envelope, read against the work rather than the page.

Doosan Machine Tools Is Now DN Solutions: What Changed

Doosan Machine Tools Is Now DN Solutions: What Changed

DN Solutions is Doosan Machine Tools renamed. The Korean machine tool business has carried four names — Daewoo Heavy Industries, Doosan Infracore, Doosan Machine Tools, and since 2022, DN Solutions — but the machines did not change with the name. The DNM, Mynx, PUMA, Lynx, NHC and DBC model families all continue under DN Solutions. What does change is the individual model designation. Doosan's current DNM series is catalogued as DNM 4500, 5700 and 6700, while older machines of the same size class are badged DNM 5705 and DNM 6705 — identical travels, different number. Buyers should check the builder's plate, the CNC control model and the spindle specification on the specific unit, and search by model number rather than by brand.
