Minimise Limescale to Boost CNC Lathe Efficiency


Monday 9 March 2026, 11:40:10 AM


Managing water hardness, particularly limescale concentration, is crucial for the maintenance of CNC lathes. High limescale levels can lead to significant operational issues by clogging pipework and reducing the stability of the system. These problems can compromise overall machine performance.

The evaporation of water from the coolant sump over time can result in increased mineral concentration. This mineral build-up can deposit onto the slideways, obstructing carriage movement and potentially damaging the equipment. It is essential to avoid high limescale concentration in the water used for coolant preparation.

High concentrations of limescale can negatively affect both the cooling system and the lubrication processes of the lathe. Regular measurement of water hardness is advised, especially in regions with hard water. The use of industrial water softeners can be effective in maintaining appropriate water parameters.
