On-Site Machining

DL RicciHydratight's range of milling machines will cover a large range of applications including keyway cutting, turbine bedplates and foundation pads. With the geniSYS 220 portable 3D CNC milling machine, large diameter surfaces can be levelled with a higher level of accuracy by utilising the laser levelling equipment.

Laser levelling equipment can be used to complement all Hydratight on-site machining where accuracy is essential when setting the equipment to existing datum’s, or its orientation to mating equipment.

The equipment can be used to carry out surveys on items such as flange faces or pump bedplates, to identify the degree of distortion prior to a machine being installed. This can help reduce down time by identifying problem areas quickly.
