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.

All C.R. Onsrud 5-axis machines have large vertical rams and "oversized" servos for fast positioning and smooth cutting.

C.R. Onsrud 5-axis machines are faster, smoother and far more rigid than our competitors' comparable machines.
