In a CNC automatic spraying machine, the flow rate is typically adjusted by an electronically controlled proportional valve or gear pump. The operator can input the target paint film thickness (e.g., 30μm, 60μm, etc.) in the control interface, and the system will automatically calculate the optimal parameters based on the spraying area and flow rate algorithm.

For minor clogging, gently clean the nozzle orifice with a soft brush; for severe clogging, use an ultrasonic cleaner to remove tiny residues from the nozzle through high-frequency vibration. Never use steel needles or wires, as this may enlarge the nozzle orifice and disrupt the spray pattern.

Common direct causes of uneven paint thickness include: • Unstable paint output from the spray gun; • Improper spray path spacing settings; • Mismatch between spray angle and workpiece surface; • Uneven spraying speed; • Poor paint atomization quality; • Inadequate equipment maintenance.

In high-end applications, such as piano lacquer panels, automotive parts, or high-gloss furniture, the spraying precision of CNC automatic spraying machines can reach within ±0.1mm, while the coating thickness control error can typically be controlled within the range of ±3 to 5μm. This level far exceeds the capabilities of manual painting.

Therefore, to allow CNC automatic spraying machines to achieve their intended high-precision advantages, it is essential to maintain a clean, temperature-controlled, and dust-free environment in the spraying area. This is the fundamental necessity of configuring a dust collector.

Water-based coatings are environmentally friendly coatings that use water as the dispersion medium. CNC automatic spraying machines have excellent compatibility with water-based coatings, and are widely used, especially in wood, plastics, electronic product casings, and automotive interior parts.

The CNC Automatic Painting Machine supports multi-layer spraying. The CNC system can preset the spraying parameters for each layer, such as spraying angle, spray volume, and spraying time. After the first layer is sprayed, the system automatically waits for the coating to dry or cure and prepares for the next layer.

The service life of a CNC automatic spraying machine is typically measured by total operating hours or years of continuous normal operation: • Standard industrial-grade equipment: 8-12 years • Heavy-duty, high-intensity equipment: Estimated lifespan: 5-8 years • With regular maintenance, some models can reach over 15 years

Before purchasing a CNC automatic spraying machine, the first step is to accurately analyze the spraying requirements of your product. Different spraying requirements will determine the type and configuration of CNC automatic spraying machine you should choose.
