Milling machines remove anywhere from just enough thickness to level and smooth the surface to a full depth removal. 2d milling provides smooth results for elevation and slope control by using a sonic averaging system. pick a reference elevated string line, surface string, poured curbs, or
With trimble gcs900 grade control system on a milling machine, you can now mill surfaces at variable depth and slope without stringlines. controlling the precise cutting depth of the mill minimizes overcutting, creates a smoother surface and reduces the need for additional costly asphalt or concrete material in the ensuing repaving process.
Pavement milling is achieved using a heavyduty piece of construction equipment known as a milling machine, or a cold planer. milling machines utilize a large, rotating drum that removes and grinds the surface of the asphalt. scrolls of tool holders cover the exterior of the drum and hold the carbide cutters that actually cut the pavement.
