Needle nozzle for cooling lubricant supply

In centerless grinding, the workpiece is held in a fixed position by a three-point support system consisting of the grinding wheel, regulating wheel and support rail. The coolant supply has several direct tasks here. First and foremost, all active grinding wheel surfaces that come into direct contact with the component must be cooled and cleaned. However, other important tasks in centerless grinding include penetrating the rotating air cushion and discharging grinding sludge from the machine bed. An oversupply of coolant should also be avoided with the three-point bearing, as otherwise an aqua-planing effect may occur. With the nozzles developed by our experts, centerless grinding with its diverse requirements can be optimally supplied. We know from experience: With centerless grinding, we can usually reduce your coolant consumption by about 60%.

Tool grinding refers to machining tasks that are necessary for the production or overhaul of a tool. These tools are often made of very hard materials due to their areas of application. This makes grinding more difficult and processing temperatures rise, which is why an adequate cooling lubricant supply is essential. The complex component geometries, for example in the case of grooves of a thread cutter and the associated changing contact areas, place high demands on the cooling lubricant supply. Thanks to the nozzles that Grindaix adapts individually to your process, sufficient cooling lubricant reaches all relevant zones that are difficult to reach and at risk of grinding burn. At the same time, we reduce the consumption of cooling lubricant, thus saving you money.

In gear profile grinding, internal gears can be ground which are machined gap by gap. Here, a sufficient cooling lubricant supply to the machining zones on both tooth flanks and on the tooth base is crucial. In addition, the cooling lubricant must be transported directly to the internal gears that are difficult to reach during gear profile grinding. Our coolant nozzles enable a precisely metered and targeted supply. The coolant supply and coolant exit speed, which have been customized by our experts, ensure that the grinding wheel is thoroughly saturated. The grinding wheel transports the coolant to the correct and hard-to-reach gaps where it is needed to prevent grinding burn.

Internal cylindrical grinding is a process used for machining internal surfaces such as bores. However, this process in particular presents special challenges for the coolant supply. The very limited space between the grinding wheel and the workpiece leaves very little room for the nozzles of the coolant supply. Even though an optimal coolant supply is essential, the coolant often does not reach the machining zone directly. Our nozzle experts develop robust yet delicate coolant nozzles for precisely such processes, which can be manufactured using both 3D printing and conventional methods. The slim design and the use of specially bent nozzle needles ensure a targeted and demand-oriented coolant supply.
