Metallographic cutting machines are common equipment for sample preparation and sampling in laboratories. Generally speaking, the frequency of use of cutting machines is very high. Although flowing water does not rot and household hinges do not get rotten, the cutting machine has a high load during operation, and the cutting process is also impactful. The internal and external environment during use is often harsh, which brings many problems. Moreover, in order to meet the needs of production and sampling, and to prevent adverse effects caused by overheating, metallographic cutting machines are usually equipped with a cooling system, which further deteriorates the usage environment.

It is precisely because there are so many unfavorable factors that maintaining the metallographic cutting machine well in daily life to avoid interference with experimental work has become a top priority. Next, let's talk about the maintenance and upkeep of cutting equipment.

1、 Check before use

Cutting machines are generally driven by electricity and have a high current load during operation. Before use, it is necessary to check whether the circuit is intact and whether there are power supply faults. Prevent leakage, electric shock, short circuit, and other situations.

2、 Visual inspection

If there is a significant change in the shape of the cutting machine, do not continue to use it. Because the cutting machine is designed with many protective devices, once the appearance changes, the user may not receive the corresponding protection, and the equipment may not function properly. Because metallographic cutting machines are electrical equipment, there may also be a risk of electric shock.

3、 Cutting cooling lubricant must be used

Although the metallographic cutting machine has undergone a lot of anti-corrosion treatment, such as anti-corrosion T-groove workbench, anti-corrosion and easy to clean inner wall epoxy resin coating, anti-corrosion treatment of all metal fuselage meeting various working conditions, stainless steel or chrome plated metal parts, etc., anti-corrosion and antirust treatment has been done almost everywhere, but corrosion is still inevitable, which is a physical necessity&mdash& Flash; Entropy increase.

There are many reasons for corrosion, the main one being that water is used as a coolant without rust prevention treatment or adding rust inhibitors such as cutting cooling lubricants. Water causes significant damage to electrical equipment, mechanical structures, and metal parts and cannot be used directly. Cutting and cooling lubricants must be added to the water in proportion and mixed before use.

Attention: The coolant needs to be replaced, and whether to replace it depends on the usage and usage time; The coolant has a lubricating effect, can alleviate impact, and is beneficial for extending the service life of the equipment.

4、 Some cutting machines require the use of lubricating grease

Some cutting machines need to be lubricated. Usually, there are one to several lubrication ports that require the addition of grease. The adding port is usually located at the positions of the screw, bearing, and loading platform, because the purpose of adding lubricating grease is to protect these components.

5、 Pay attention to regular cleaning

I personally recommend doing a simple cleaning every time you use it, and regularly performing meticulous cleaning. When replacing the coolant in the water tank, the water tank can be cleaned.

6、 Open protective cover

Due to the use of the cutting machine, the cutting chamber is often in a damp environment and difficult to dry. If conditions permit, the protective cover can be opened and the cutting chamber dried, which is beneficial for protecting the equipment. The premise is to have good indoor ventilation and not let the smell of the cutting room affect others. For safety reasons, after drying, the protective cover can be closed or the contact of idle personnel can be restricted.

7、 Contact the manufacturer for maintenance and upkeep

If the equipment level is high, there is no dedicated person responsible, and there is no maintenance experience, you can contact the manufacturer, who will be responsible for maintenance.

8、 Contact the manufacturer if a malfunction occurs

The first seven items mentioned in this article can be used as a reference for daily maintenance and upkeep of equipment. If the equipment malfunctions and users have not received maintenance training, it is recommended to contact the manufacturer and have a dedicated person solve the problem.
