Abstract
The milling machine disclosed herein offers significant advantages over prior milling machines, particularly in the field of milling composite panels. The structure of the milling machine, having a C-shaped frame with a clamping mechanism that cooperates with roller transfer balls, provides an accurate and stable reference during the milling operation. A vacuum system substantially eliminates the dust produced during the milling operation, so that the machine is cleaner and grinds more accurately. An electrical system, having a retractable bit control and emergency stopping modes, facilitates even more accurate grinding without undesirable results.
