Exporting Files for CNC

Hello everybody, hope someone can help.

    I  am using Corel X3 to draw and export files to cut artwork on a CNC machine using Mach3 software. My problem is that Corel is exporting arcs and circles as short line segments causing the machine to cut jerky, starting and stopping at every node. I need to find out how to export the files as clean as possible, either in .eps, or .dxf. From what I am gathering, Corel exports very poorly and in low resolution. Can somebody point me in the right direction? I will post a file for someone to look at.  Thanks,
