- Targeted lubricoolant supply to the machining site
- Highly robust
- Suitable for very confined spaces
- Available in many supply widths
To extensively customize a nozzle to your particular grinding task, the Grindaix team employs 3D printing during nozzle manufacture. However, we only recommend the use of 3D-printed nozzles where this really makes sense. It is not generally the case that innovative 3D printing can be used meaningfully across the entire range of mechanical parts. That said, the undisputed advantages of this process lie in the production-independent, geometrical freedom, which allows the generation of far more complex geometries than is possible with conventional manufacturing operations. This enables the production of nozzles which sufficiently supply sites in the machining process that could not be reached using lubricoolant nozzles produced by conventional means.
Both geometrical restrictions (e.g. assembly space, collisions, etc.) as well as functional drawbacks (e.g. pipe friction losses) can be circumvented with 3D printing. Where it makes sense we can produce your future Grindaix nozzles using state-of-the-art 3D printing processes. We can carry this out quickly and free of all restrictions posed by conventional production processes – with perfect customization to your particular grinding tasks. To produce your nozzles, we use plastics as well as stainless steel and titanium alloys.
The challenges of producing Grindaix nozzles using 3D printing lie in the choice of laser sintering process parameters, the general material selection and composition as well as in maintaining a consistent metal powder granularity. Furthermore, process control is of great importance in terms of layer thicknesses, sintered densities and the associated surface qualities which can be achieved on the external and internal surfaces. This determines the scope of subsequent reworking following the actual printing process. All necessary steps must be combined attractively from a cost standpoint and result in a significant user benefit – in other words, maximum operational cost effectiveness.

Our 3D printing nozzles in use - examples
The 3D print nozzles from Grindaix are individually adapted to the grinding processes and space conditions in the machines. The 3D print nozzles can be used in a wide range of grinding processes due to their freedom of production and geometry. This ensures an optimum lubricoolant supply from internal cylindrical grinding to crankshaft grinding.
Advantages for grinding processes thanks to the 3D printing nozzles:
- Flow-optimized nozzle geometry
- Can be combined with the gFlex from Grindaix
- Defined outlet velocity
- can be used in the tightest installation spaces
- Various geometries possible
- production-independent
Internal cylindrical grinding
Internal cylindrical grinding is a process for machining internal surfaces, such as bores, and places special demands on the coolant supply (coolant lubricant). The limited space between the grinding wheel and the workpiece offers little room for the coolant nozzles. Although an optimum coolant supply is essential for the success of the process and the prevention of grinding burn, in many cases the coolant does not reach the cutting zone directly. Grindaix GmbH offers a solution here with specially developed 3D printing nozzles that meet the special requirements of these processes. Thanks to 3D printing, various geometries are possible so that all grinding machines can be equipped and thus ensure a targeted and demand-oriented coolant supply. It does not matter which material is required for the 3D printed nozzle.
Crankshaft grinding
Crankshaft grinding is a manufacturing process in which the crankshaft is ground very precisely in order to achieve a high surface quality. The challenge with the coolant supply lies in the complex geometries of the crankshaft, which makes it difficult for the coolant to reach the cutting zone and can impair quality. The 3D printed coolant nozzles from Grindaix GmbH have been specially developed to supply coolant to grinding processes that are difficult to reach. To ensure that all surfaces of the crankshaft are supplied with coolant, the design of the 3D printed nozzle also takes into account the supply via the grinding wheel. Production is carried out by 3D printing professionals who work precisely according to the designs of our coolant supply experts. Together, this results in a nozzle that is individually adapted to your process and makes complex geometries possible.

The cooling lubricant jet of the 3D printing flat jet nozzle
The 3D flat jet nozzle from Grindaix GmbH has been specially developed for flat profile grinding. It enables a reliable and targeted coolant supply where conventionally manufactured flat jet nozzles cannot be used. Nevertheless, the 3D-printed version offers a cooling lubricant supply that is just as precise as the conventionally manufactured coolant nozzles. Take a look at the coolant outlet speed and jet of the 3D printed flat jet nozzle:
Equipment for the Grindaix 3D nozzles
The right equipment for Grindaix 3D nozzles helps to increase productivity and longevity. However, finding the right equipment for nozzles is often a challenge, which is why we have developed equipment that meets the requirements and is precisely tailored to Grindaix nozzles!
The Coolant Protectors from Grindaix GmbH make it possible to provide almost any nozzle geometry with protection. This serves to protect against wear and to dissipate and stabilize air. Our coolant pressure gauges, as well as the Coolant Display and the Coolant Pointer, have been developed to make the alignment and display of your coolant data better and faster. The quick-change systems also have the task of exchanging different nozzle variants and gFlex lengths quickly and practically.
