Product Description

Designed and built to be the heaviest, fastest, and highest performing machines available in the world at any price, the Onsrud Extreme Duty Series CNC Router is truly our "No-Compromises" model. We start with the largest standard cast iron frame offered anywhere in our marketplace today. The massive cast iron bridge on the HD Series has over double the cast iron of even our legendary C Series models. The cast iron frame is then mated to our one-piece, self-supportive, heat-treated, stress-relieved and normalized, internally-reinforced, thick-walled, steel base for unrivaled weight, mass, rigidity, durability, feeds and speeds. We then use only the highest-end, top-shelf, non-proprietary and readily available components in the world today to offer you the most technologically advanced Onsrud ever. Many of the standard features on the Extreme Duty may be options and/or upgrades on our other C.R. Onsrud models, but they are not even offered by the competition.

When you require unrivaled feed rates, machining speeds and rapid traverse rates, when your jobs demand the ability to run the largest diameter tool and take the deepest, heaviest cuts in the most dense and unforgiving materials, when you insist on the highest possible accuracy and repeatability, when you want the best possible machined finish that tooling can provide... if you want the lowest operating maintenance cost, the lowest number of occurrences and the shortest duration of downtime... when you want to have the assurance and satisfaction of knowing beyond a shadow of a doubt that you have purchased the biggest, heaviest, best built, fastest, most powerful, most durable and most productive machine available on the market today, then the C.R. Onsrud Extreme Duty Series is for you!
