Product Description

The Introduction of the Five Axis High Rail Gantry Series machining centers and mills signifies C.R. Onsrud's continued and growing commitment to the advanced materials industry. The HR Series was designed and built with a focus on the needs of manufacturers to produce high precision non- ferrous, light ferrous, or composite products that require a sizable working envelope to accommodate their large sizes or awkward shapes. To this end; Finite Element Method design, and Finite Element Analysis was performed extensively throughout the design and engineering processes. Thus, you can be confident that this machine will provide the accuracy, repeatability, speed, structural rigidity, and high material removal rates demanded when machining structural aluminum components, aircraft surface skins, automotive molds, helicopter blades, plugs for boat molds, and structured insulated panels just to name a few examples.

C.R. Onsrud High Rail Gantry machines feature a unique frame design that specifically addresses the needs of non-ferrous metals, plastics, composites, and light steel; whether wet or dry cutting. Two rows of heavy steel support pillars are joined at their precision machined shoulders, forming support walls, onto which the X-Axis guide ways and drive systems are mounted. A massive moving bridge featuring over 4-foot bearing spacing, spans these stationary support walls to form the Y-Axis. Electronically tensioned, dual synchronous direct drives on each end of this bridge allow for smooth, fast, precise, and back-lash free motion. This design allows the electronics and mechanical drives to be located completely outside of the machining envelope and prevents their potential contamination from wet or dry machining. This design also eliminates the vertical pillars present in many other moving bridge machines. Eliminating the vertical columns minimizes potential frame deflection or distortion, and increases overall volumetric accuracy. This design also allows for the more efficient and more rapid movements of a substantially larger and heavier bridge; and for the use of a much taller and stiffer z-ram. A taller Z-Axis cutting envelope is made possible, and the machine is able to be more rigid and more accurate at these taller working heights.

Safety and usability have always been hallmarks of Onsrud machining centers. As a result of these concerns, side panels and doors completely surround the working envelope to help ensure safe operation, reduced noise levels, and to control debris. When contamination concerns are more critical, the optional retractable bellows roof can fully protect the surrounding environment from fine airborne particulate or contamination. Also, there are optional lighting, down-draft dust collection systems, and auger or conveyor systems, making it possible to better control and capture most of the dust and particles. The roomy open design gives easy unobstructed access with a forklift or overhead crane.

With our largest variety of options, sizes, upgrades, and possibilities, the flexible High Rail Gantry series is built and engineered-to-order, around your products, your requirements, and your needs. The High Rail Gantry makes use of the foundation and floor of your facility, to deliver the heaviest bed load capacities available on any design. The floor inside the machine is left free and uncluttered, ready for any table, tooling, fixture, clamping, or POGO part holding system. Various table options include Above Floor Roll- In, Above Floor Fixed, Flush Mounted or Pit, Aluminum T-slot, Steel T-Slot, Drilled and Tapped, Slab Plate, Magnetic, or Vacuum. Multiple spindle options range from higher RPM lower torque routing spindles to lower RPM higher torque milling spindles with flood, mist, dry, or near-dry capabilities. Large capacity automatic tool changers are available with HSK-63F or HSK-63A tooling. The High Rail Gantry is available with open architecture controllers from OSAI or FANUC, to deliver the best 5-Axis machine motion and the most programming capability and flexibility. Both available controller options include Tool Center point Programming (TCP) and High Speed Machining (HSM) as standard. And, all of the controller options are compatible with optional volumetric laser compensation and accuracy enhancing linear scales on all axes.
