CLEANING GRINDING WHEELS

The cleaning nozzle RD-LP 55 belongs to our product portfolio of high-pressure
cleaning nozzles. Equipped with six flat spray nozzles, they free the grinding wheel
of chip residues and impurities in a reliable way. This not only improves the grin-
ding result but also increases the service life of the grinding wheel. Free pores are
additionally flooded with lubricoolant, which has a positive impact on the cooling
effect in the machining zone.
Despite their very good cleaning performance, our nozzles only consume low
amounts of lubricoolant. These and other cleaning nozzles are available in all widths.
During grinding, material removal leads to loading of the grinding wheel surface. The pore spaces of We adapt the number of flat spray nozzles to the required width.
the grinding wheel become clogged by machining residues, such as chips, and can no longer take
up any lubricoolant. Besides this, the residues in the grinding wheel rim have a negative impact on
the surface quality. Influencing factors are the process-related chip formation geometry and the ma-
terial to be machined. If the level of loading on the grinding wheel surface is too high, the machining ADVANTAGES

Low lubricoolant consumption Cleaning of grinding wheel
The use of special high-pressure cleaning nozzles from Grindaix for removing residues from the pores
grinding wheel pores brings many benefits. High exit speed Increase in the service life of
the grinding wheels
Grindaix cleaning nozzles are available in two types. Low pressure: Here we achieve the same
cleaning performance at a supply pressure of below 25 bar and can thus use more cost-efficient
centrifugal pumps which are less prone to wear. High-pressure type: Supplied upon customer re-
quest. Here, screw spindle pumps are used, as considerably higher lubricoolant pressures (>25 bar)
are needed.

Although at 20 bar, the operating pressure of the Grindaix cleaning nozzles is still high – and this is
often necessary for achieving an optimum cleaning result – our cleaning nozzles only consume low GEAR TOOTH
volumes of lubricoolant.
PROFILE GRINDING
When cleaning grinding wheels, the orientation of the cleaning nozzles is also important. Here, it is
possible to spray in the same direction that the grinding wheel is rotating or counter to it, or else
vertically onto the grinding rim. It is also possible to use one row of cleaning nozzles or several. Our high-pressure cleaning nozzle RD-LP 70 is a flexible solution for cleaning
grinding wheels during gear tooth profile grinding. The nozzle applies lubri-
