Release agent spraying in laser processing machines
Consistent, reproducible release agent application for stable engraving quality
In laser processing machines used for engraving printing cylinders, extremely fine chips are generated during the machining process. These chips must continuously and reliably slide away from the engraving point. A targeted, pulsation-free release agent spraying process supports controlled chip sliding and contributes to stable machining conditions and consistent engraving quality.
A micro annular gear pump mzr-2921 supplies the release agent within a flow rate range of 0.1 to 18 ml/min and feeds it into a two-fluid spray nozzle. Spraying takes place directly at the machining point. The spray nozzle and the pump operate in synchronization, ensuring precise and reproducible release agent application.
What requirements does release agent spraying in laser engraving processes impose?
Consistent engraving quality requires:
- constant flow rates at low dosing volumes between 0.1 and 18 ml/min
- pulsation free spraying for homogeneous wetting
- reliable sliding of fine chips
- stable operation on moving machine axes
- compact integration within limited installation space
A constant and reproducible release agent spraying process is essential for maintaining process stability throughout the entire processing cycle.
How is the micro annular gear pump integrated into the machine axis?
Due to its compact design, the self-priming micro annular gear pump mzr-2921 is mounted directly on the moving engraving axis. This configuration minimizes hose lengths and supplies the release agent directly to the two-fluid nozzle. The result is responsive spray control and stable spray characteristics even during dynamic axis movement.
The medium used is an oil-water emulsion with aqueous viscosity. The DC servo drive with integrated microcontroller is controlled via RS-232 and can be precisely integrated into the control architecture of the laser processing machine.
What benefits does this provide for machine and plant engineering?
By integrating the micro annular gear pump, machine manufacturers can:
- achieve stable and uniform release agent spraying
- maintain consistent machining conditions during engraving
- actively support controlled chip sliding
- reduce installation space through compact pump design
- seamlessly integrate the spray system into existing machine control architectures
The micro annular gear pump therefore provides a compact and process-reliable solution for high-quality laser engraving systems in special machine engineering.
