In the field of graphite machining, the choice between wet and dry processing techniques significantly impacts the efficiency, precision, and longevity of CNC machine tools. This article delves into the stability advantages of wet graphite machining technology over traditional dry machining, supported by industry - measured data.
Wet graphite machining employs coolant for immediate flushing during the processing. This process has two main functions. Firstly, it effectively controls heat. In dry machining, the heat generated during the cutting process can reach up to 500°C, which may cause thermal deformation of the workpiece and tool. In contrast, wet machining can keep the temperature below 100°C through the continuous cooling effect of the coolant. Secondly, it helps in cleaning graphite dust. Graphite dust is not only harmful to the health of operators but also can cause serious wear on machine tool components. The coolant can wash away the dust in time, reducing the probability of dust accumulation.
To achieve the best results in wet machining, it is crucial to optimize the technical parameters. The flow rate, pressure, and spraying method of the coolant all play important roles. For example, in the mass production of high - precision molds and electrode graphite products, a coolant flow rate of 15 - 20 liters per minute and a pressure of 2 - 3 bar are often recommended. Regarding the spraying method, a targeted spraying directly at the cutting edge can ensure the most effective heat dissipation and dust removal.
| Parameter | Recommended Value |
|---|---|
| Coolant Flow Rate | 15 - 20 L/min |
| Coolant Pressure | 2 - 3 bar |
Dry machining has several significant risks. The high - temperature environment can cause thermal deformation of the workpiece, reducing the dimensional accuracy by up to 0.05mm. Moreover, the graphite dust produced in dry machining can accumulate in the machine tool, increasing the wear of moving parts and reducing the service life of the machine. In contrast, wet machining effectively mitigates these risks, improving the processing accuracy and the reliability of the equipment.
In the era of intelligent manufacturing, wet machining plays a key role in automated continuous production. For example, in some large - scale graphite product manufacturing enterprises, wet machining centers can operate continuously for 24 hours, with a product qualification rate of over 95%. This high - efficiency and high - quality production mode meets the needs of modern manufacturing.
