en.Wedoany.com Reported - The China XCMG XM505 milling machine is the main model for repairing diseases in municipal streets, alleys, community roads, and around manhole covers. It is equipped with a standard 500mm milling drum and 54 sets of cutting tools. During daily construction, tool wear not only increases the procurement cost of accessories but also frequently interrupts the construction schedule.

Based on the working characteristics of the XM505, the following is a technical solution for tool selection and replacement.

Recommended Tool Selection

For asphalt road conditions, the X5 reinforced tool holder is recommended. It features a tool removal slot design, large-diameter washers to protect the tool holder, and a high-penetration tip design, suitable for general working conditions.

For concrete road conditions, the X2 slotted tool holder is recommended. It has outstanding rotation performance, is equipped with wear-resistant washers to protect the tool holder and large-diameter cylindrical carbide, and undergoes special heat treatment, providing superior wear resistance and excellent rotation characteristics.

Abnormal Tool Wear Issues and Solutions

Common problems include tool non-rotation, carbide tip breakage, carbide tip loss, and tool holder wear.

Milling Machine Tool Replacement Method

When replacing tools, the milling drum drive must be turned off. Due to inertia, the milling drum will continue to rotate for a short time. Do not approach the milling drum until it has come to a complete stop.

Turn off the engine and store the key properly to prevent accidental engine start.

Open the rear door and use a punch to knock out the worn or damaged tools.

The milling drum can be rotated using an electric slow-rotation device to inspect or replace all cutting tools.

Finally, install the new tools.

Scientific maintenance can extend the service life of the tools. When wear exceeds the limit, replace them promptly to avoid secondary failures and additional costs.
