Precision Dosing Units

In punching and forming processes, each lubrication point must be reliably supplied with the required amount of lubricant. Fluctuating machine cycles, high stroke rates, and multiple independent lubrication points make it difficult to achieve uniform dosing. Applying too much lubricant increases lubricant consumption and can interfere with downstream processes. Conversely, an insufficient supply can cause tool wear, scrap, and quality issues.

Precision metering units adjust the lubricant supply to match the press stroke or machine cycle. Metering pumps enable the reproducible application of even the smallest quantities. Depending on the application, dosages as small as a few nanoliters per lubrication point are possible.

The systems support a demand-based lubricant supply through:

• Up to six freely programmable outputs
• Separate supply to individual lubrication points
• Precise dosing with varying cycle rates
• Combination with roller conveyor lubricators, nozzle bars, and spray systems
• Connection of tool lubrication systems and minimum quantity lubrication nozzles
• Use with high-speed automatic punching machines and conventional presses

Consumption and order data are recorded and documented by the control system. This allows lubricant quantities to be analyzed in a traceable manner and used for quality assurance and process documentation.

The modular design allows for adaptation to different machines, lubrication points, and production conditions. Mobile models with an integrated reservoir and fill-level monitoring also facilitate integration into existing production facilities.
