XL-Circular Mills are specifically designed to machine horizontal or near horizontal circular faces from 20’ to 150’ diameter. Like its smaller brother, XL-Circular Mills are relatively compact and fast to assemble on the work piece because it does not require large bearings and housings to support a rigid arm from the center of the work piece or complex and precisely set rails to run on. Instead a milling head, rotating at the diameter to be machined is supported on wheels rolling on the surface being machined and connected by beams to a central pivot post.
The machine cuts a flat plane because the wheels are adjusted to maintain the milling cutter at a level plane by laser reference, which has been set to the desired plane. Again, like Circular Mills, many other concentric and parallel faces can be machined from a single setup by relocating the milling cutter.
