Innovation and Simplification Hallmarks of Bomag Cold Planer Milling Machines

Bomag’s two new models of milling machines, the BM500/15 and the BM600/15, feature an innovative rotor geometry to reduce vibration, simplified drum replacement, and increased service life.

The new rotor geometry uses optimally arranged teeth and a thick shell for uniform, low-vibration and very 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. The centre supports are precisely mounted in the milling pockets for maximum power transfer and quick cutter maintenance.

Furthermore, drum replacement has been drastically simplified. Featuring an industry exclusive rotor mount design, the cutting width of the machines can be adjusted with the removal of just a few bolts. All cables and hydraulic hoses are clearly routed away from the door, giving the operator easy access to the drum. Whereas rotor replacement on other models typically takes four to five hours, the unique design of the BM500/15 and BM600/15 shortens the job to 30 minutes or less.

The units are powered by a 125-hp Deutz liquid-cooled diesel engine. 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.

The machines have three variable cutting speeds to optimize milling performance. For operating next to walls, the conveyor belt assembly can be quickly and easily removed by one person in less than five minutes. To keep the cutter cool and enhance service life, the units include a water system with spray control.

The units are designed so the operator can always work from a seated position where he can clearly see the milled edge.
