Wirtgen milling machine maintenance is introduced       

XM series of road milling machine is one of the main equipment maintenance of asphalt concrete pavement construction, mainly for the renovation of highway excavation, urban roads, airports, etc of asphalt concrete surface layer, can also be used to clean the surface upheaval, oil wave, crazing, rutting and other defects, can also be used to the excavation surface pits and grooves, and galling and the surface of cement pavement layer dislocation milling.

XCMG road milling machine with advanced performance, high working efficiency, simple construction process, milling depth is easy to control, convenient and flexible operation, good maneuverability, old material milling can be directly recycled, is the ideal equipment for pavement maintenance mechanization.

1. First, the machine must be operated by professional staff, and carefully read the operation manual or instructions;

The main work part 2, milling machine as milling cutter, bearing shims, milling drum, and pavement friction due to long time operation, consumption is the fastest in this part, the regular replacement, check in order to extend the service life of the machine;

3, for the sake of safety in milling machine maintenance before, should first put the power broken motor, preferably by a qualified mechanic;

4, cutter shaft should be daily check, if the above grinding groove more than 25 of the diameter of the cutter shaft, to replace the. Generally speaking, the life of cutter shaft is half life of tungsten steel milling cutter. From the square area, the life, the milling depth of 5mm is about 350-500 square meters. But please note that there are many factors that can affect the life of cutter shaft, so to daily check;

5, each operation of milling machine to check the motor turning and milling machine, all parts of the fastening pieces are loose (must tighten loose)

6, each used for a period of time, the milling machine bearing grease. A grease, while playing side milling drum rotation, the grease evenly coated on the entire bearing;

The machine with the naked eye examination in 7, each operation of milling machine: all fasteners are tightened? Are there obvious wear or tear of parts? Check the bearing, check the protective cover is covered;

8, each operation of milling machine, check the belt tightness. The new belt in 4 operation hours should re adjust the degree of tightness must maintain proper belt tightness, to transfer the engine output horsepower to the cutter drum, when a tight belt will be easy to wear, but also shorten the service life of the bearings, such as broken marks, severe wear belts should be immediately replaced;

9, in general, cutter cracking is very rare, if occurred, usually have the following situations: A: cutter milling drum arranged irregularly; B: single milling is too deep; C: the removal of different types of pavement milling cutter is not suitable; D: milling surface strength is too large;

10, each change cutter arrangement, check cutter shaft and bearing. If the wear grooves appear on the shaft, need to replace the new change, and change the bearing to the shaft.

11, milling machine milling drum if properly maintained, usually can be used for 3 months. In the more milling cutter or maintenance, check the central axis of milling drum whether there is cracks, shaft sleeve hole is oval, weld seam whether there is cracks, if found any damage, must replace the new drum.
