In the graphite processing industry, graphite dust is a significant threat to the normal operation of CNC machine tools. First, graphite dust has strong corrosiveness. When it adheres to electronic components, it can gradually corrode the circuit boards and chips of the machine tool, leading to malfunctions or even permanent damage. According to industry statistics, about 30% of electronic component failures in graphite processing machine tools are related to dust corrosion.
Second, graphite dust can easily enter the guide rails and ball screws of the machine tool. As time passes, it accumulates and hardens, causing blockages. This not only affects the smooth movement of the machine tool's moving parts but also increases the wear and tear of the guide rails, reducing their service life. It is estimated that the guide rail wear rate of machine tools in a dusty environment is 2 - 3 times higher than that in a clean environment.
Finally, the presence of graphite dust can seriously affect the machining accuracy of the machine tool. Even a small amount of dust on the worktable or tool can cause errors in the machining size and surface finish of the workpiece, resulting in a decrease in product quality. In some precision machining scenarios, the machining accuracy error caused by dust can reach up to 0.05mm.
The DC6060G dry vacuum graphite machining center adopts a combination of a full - sealed cover and a high - efficiency dust collection system to effectively control graphite dust. The full - sealed cover is made of high - strength and wear - resistant materials, which can completely isolate the machining area from the external environment, preventing dust from escaping during the machining process.
The dust collection system is the key to controlling dust. It uses a powerful suction fan and a high - precision filter to quickly suck the graphite dust generated during machining into the dust collection box. The filter can effectively capture dust particles as small as 0.1 microns, with a dust collection efficiency of up to 99%. The coordinated operation of the full - sealed cover and the dust collection system forms a double - protection mechanism, which greatly reduces the impact of graphite dust on the machine tool.
Regularly check the sealing performance of the full - sealed cover. Look for any signs of damage, such as cracks or loose seals. If any problems are found, repair or replace the seals in time to ensure that the dust cannot leak out of the machining area.
Clean the filter and dust collection box of the dust collection system regularly. A clogged filter will reduce the suction power of the dust collection system, affecting its dust collection effect. It is recommended to clean the filter at least once a week and empty the dust collection box when it is 80% full.
Keep the working environment of the machine tool clean and dry. Avoid excessive humidity, as this can cause the graphite dust to agglomerate and increase the difficulty of dust control. At the same time, ensure good ventilation in the workshop to quickly discharge the dust in the air.
Regularly lubricate the moving parts of the machine tool, such as the guide rails, ball screws, and spindles. Use high - quality lubricants to reduce friction and wear, ensuring the smooth operation of the machine tool. The lubrication cycle should be determined according to the machine tool's operating instructions.
Record the operating status of the machine tool, including the operating time, machining parameters, and any abnormal phenomena. This record can help you detect potential problems in time and take corresponding maintenance measures. It is recommended to record the operating status every day.
To facilitate on - site execution and standardized management, we have prepared a detailed inspection checklist. This checklist clearly lists the inspection items, inspection frequency, and inspection methods for each maintenance point. Here is a simple example:
| Inspection Item | Inspection Frequency | Inspection Method |
|---|---|---|
| Sealing of the full - sealed cover | Once a week | Visual inspection, air leakage test |
| Filter of the dust collection system | Once a week | Check for blockage, clean if necessary |
