Konrad Seidler MINIMAXX 1800

For sale is a high-quality CNC carousel turning, drilling, and milling center from the German manufacturer Konrad Seidler from Neuss – Holzheim, model: MINIMAX 1800, manufactured in 2013.

The machine comes from its first owner and was used in a single-shift operation in our own production facility. After the commissioning of a new manufacturing solution, the machine was decommissioned, extensively overhauled, and has only been used to a limited extent since then.

The machine is in fully functional, operational, and regularly maintained condition. An inspection and a test run under power can be arranged at any time.

It is particularly worth mentioning the extensive general overhaul of the drilling/milling spindle in 2025, which brought a major wear component of the machine back to as-new condition.
