Bomag’s BM500/15 and the BM600/15 both feature new rotor geometry to reduce vibration, increase service life, and simplify drum replacement. The rotor geometry features optimally arranged teeth and a thick shell for uniform, low-vibration and precise cutting. The edge cutter is also designed to produce a smooth edge with minimum damage, which helps reduce extra costs and ancillary work for the contractor. To minimize downtime, the diagonal cutters protect the rotor when driving around bends, and they prevent abrasion to the bracket edges.
Furthermore, drum replacement has been drastically simplified. The cutting width of the machines can be adjusted with the removal of just a few bolts. All cables and hydraulic hoses are routed away from the door, allowing easy access to the drum. According to the company, rotor replacement takes 30 minutes or less.
The new mills are powered by 125 hp Deutz liquid-cooled diesel engines. The BM500/15 offers a standard cutting width of 19.7 inches, whereas the BM600/15 delivers a 23.6-inch cutting width. Both models feature a maximum cutting depth of 8.3 inches and a milling radius of less than 10 inches. They are ideal for repair work, the removal of asphalt strips, fine milling work, trench work, joint cutting, or milling close to manhole covers and curbs.
Operator visibility and comfort are maximized on the new machines. The units are designed so the operator can always work from a seated position where he can clearly see the milled edge. The steering wheel, armrests, and seat are insulated to reduce vibration.
For operating next to walls, the conveyor belt assembly can be quickly and easily removed. The conveyors on the BM500/15 and BM600/15 can be disconnected by one person in less than five minutes.
The machines have three variable cutting speeds. All controls, such as the cutting speed and depth, are digitally and clearly displayed in the operator’s line of sight.
To keep the cutter cool and enhance service life, the units include a water system with spray control. It features an automatic setting, which only uses water when the machine is planing. The system also controls the spray volume to eliminate unnecessary water consumption and decrease the number of refills needed. Maintenance of the water system is kept simple, thanks to the easy-access spray bar that can be quickly removed and serviced without tools.
Available options include a weather protection roof, split rear-scraper door, working lights, and a four-wheel version for optimal traction and stability. Various milling drum options are also offered.
