The Super Heavy Duty - yet super fast - 5 Axis Series CNC Routers carry the "No Compromises" design of our Extreme Duty machines to the next logical, power-production level. Ranging from the twin table, fixed bridge models of the HD series to the moving gantry machines with super-large 15ft x 60ft fixed tables, you won't find a heavier, faster, higher performing machine anywhere - at any price.

On the fixed bridge HD Series, Onsrud starts with the largest standard cast iron frame offered anywhere in the marketplace today.

The massive "oversized" cast iron bridge on the HD Series has over double the cast iron of even our legendary C Series models. The massive cast iron frame is then mated to our one-piece, self-supportive, heat- treated, stress-relieved and normalized, internally-reinforced, thick-walled, tubular steel base for unrivaled weight, mass, rigidity, durability and super fast feeds and speeds.
