Metallographic cutting machine is one of the main equipment for conventional sample preparation in metallographic laboratories, and every large sample sampling cannot be separated from the precise cutting of metallographic cutting machine. Suitable for cutting metallographic specimens of various metal, non-metal, and rock materials. It is a common equipment in metallographic testing laboratories of factories, scientific research, and universities.


The metallographic cutting machine uses a high-speed rotating ultra-thin cutting saw blade to cut metallographic samples. Unlike ordinary cutting machines, it is precise and can be precise to the micrometer level. It can cut very small samples to meet research and testing needs. Another advantage is good heat dissipation, no obvious deformation or damage to the cut section, and no burns caused by heating. Metallographic cutting machines are generally equipped with automatic cooling circulation devices, which can automatically supply water for cooling while cutting, and timely take away the heat generated during cutting to avoid changing the metallographic structure of the sample due to heat exposure. Due to its higher requirements compared to ordinary cutting machines, it is also necessary to be more precise during use. Some details need to be paid more attention to in order to ensure the safe and reliable operation of this high-speed rotating machine. The editor has summarized some daily usage precautions to share with friends.


To enhance the safety and reliability of metallographic cutting machines, the following points should be noted during the use of metallographic cutting machines:


1. Stable and firm workbench: It is required that the workbench on which the metallographic cutting machine is installed should be relatively stable and firm, and the platform should be kept level. Only in this way can the supporting wheels at the four corners of the metallographic cutting machine base be leveled, installed firmly, and rotated flexibly. Ensure that the machine is placed in a balanced and reliable manner, and there is no obvious vibration during operation.


2. The protective cover must be safe and reliable: The cutting chamber of the metallographic cutting machine has a transparent protective cover. Only when the protective cover is fully locked can the cutting operation be started. This not only prevents misoperation and increases safety, but also prevents cutting debris and coolant splashing out, which is safe and environmentally friendly.


3. Power off first, then replace: When the metallographic cutting blade needs to be replaced, the machine must be shut down and the power must be cut off before removing the old cutting blade and replacing it with a new one. When installing the cutting blade, it is necessary to follow the installation procedure, and do not try to save time to avoid phenomena such as loose fastening, eccentricity, and imbalance, which may lead to hidden dangers.


4. Formal operation after balance test: After replacing the cutting blades of the metallographic cutting machine, a trial operation should be conducted to observe whether there is obvious vibration. Only after confirming its normal operation can it be put into use.


5. Grounding protection: Every device must have grounding protection, which goes without saying and must be dropped at times.


6. The fixed clamping device should be intact: fixed clamping devices such as vises and fixtures should be flexible in operation and able to clamp reliably; The handwheel, screw, nut, etc. must be in good condition to ensure that the sample can be firmly clamped and increase safety.


7. Workplace safety: Metallographic cutting machines are not allowed to be used in places with explosive dust.


8. Power off and clean after use: After use, cut off the power supply, clean and place it properly. Although this may not seem obvious, keeping the equipment clean for a long time can help extend its lifespan and improve its cutting ability

    The above are some small details summarized by the editor that are often overlooked by everyone. Generally speaking, it is not a big deal, but we are not afraid of ten thousand. We are afraid that in case of an accident, everything will be too late. For the safety of ourselves and others, let your metallographic cutting machine operate safely and reliably. You need to take good care of these details.
