The half-lane Roadtec RX-600e milling machine is now equipped with the ACE grade and slope control system. The automated control of elevation or ACE system from Roadtec uses a network of grade and slope sensors combined with one central microcontroller that is designed to automate the elevation of the milling machine.

The cold planer is available with four-track assemblies or optional three-track assemblies. Milling machines with three-track suspensions are expected to be more maneuverable in the cut, lower in weight, while four-track machines are designed to provide greater tractive effort and flotation, according to the manufacturer.

The machine is designed to allow contractors to cut up to 13-in. (33 cm) deep with width of 6 ft. 3 in. (1.9 m), 6 ft. 7 in. (2 m) or 7 ft. 2 in. (2 m). A two-stage front load-out conveyor, with 60-degree swing to either side, is intended to provide ample loading capacity.

The mainframe is constructed from A656 grade 80 steel, which is said to offer twice the yield strength of mild steel found in many machines on the market. Steering of this machine is performed from the tops of the front legs using steering keys that are replaceable. This design requires no linkage under the primary conveyor between the front legs. Four steering modes include, crab, coordinated, rear only and front only.

The cut material conveyor is 32-in. (81.3 cm) wide with 1-in. (2.5 cm) tall molded cleats, and infinitely variable speed. The conveyor features pulleys designed to be self cleaning, releasing wet material from the conveyors to increase efficiency. Canvas conveyor covers also comes standard, designed to provide better access.

The cutter housing and drum are modular allowing it to be interchanged with other width housing and drums. The inside walls of the cutter housing are fully lined with replaceable chromium-clad wear plates.

Specialty cutter drum designs are available from wide spaced excavating patterns to fine spaced micro milling patterns as well as double hit drums which are designed to improve production without sacrificing quality of cut. Multiple tooling options are available including Sollami, Kennametal and Keystone Quick Change systems. Roadtec can design custom drums to meet user applications. All of the cutter drums are designed and built using three-dimensional solid modeling and robotic welding.
