If a linear traversing movement is to be achieved in CNC milling and turning machines in particular, the decision is often made to use a threaded rod in combination with a lead screw nut. As reliable as this solution may be, it still leads to a wear problem that should not be underestimated. Depending on the specific machine application and the use of the threaded rods within the system, by-products from the machining process such as metal swarf or simply dust can clog the surfaces and gaps of the thread over time. If the components are not checked and cleaned regularly, they contribute to faster wear of the thread over time, which can have a negative impact on the performance and downtime of the machine. Careful consideration of the choice of components at an early stage can bring great benefits later on.
