Insert milling machine stops during the milling process (M10x, M151, M202, M251, M30x)

If a single-pass milling machine suddenly stops during the milling process, there can be various reasons for this. Often, however, it is simply because the axis motors have to use too much energy to move the axes. This can be caused by a lack of lubrication, but also by a blunt milling cutter or a feed rate that is set too high. As the machine's control system has a current limiter for the axis motors, it issues an error message if the set value is exceeded.
If the milling process runs without milling material, this indicates one of the above-mentioned causes or a combination of these.
Therefore, check regularly whether the milling cutter is still sharp, the axes have sufficient lubrication and the feed rate is adapted to the hardness of the milling material.
To further reduce friction when driving the axles, it can help to rub a little oil into the sealing lips in which the axles are guided. The use of WD40 is not recommended, as this agent can penetrate into areas where it has a counterproductive effect due to its strong creeping properties and can cause faults that are difficult to locate.
