Maintenance points for metallographic grinding and polishing machines
- Regular inspection
Regular inspection of the metallographic grinding and polishing machine can not only increase its service life, but also effectively reduce the occurrence of metallographic grinding and polishing machines. Therefore, enterprises can organize personnel to inspect once a month or quarterly. The most important thing is to inspect the metallographic grinding and polishing machine and solve various minor problems and failures of the equipment. - Regular cleaning
The main reason is that the metallographic grinding and polishing machine will produce a large amount of waste after long-term use, which contains a large amount of hard metal materials. These metal shavings, which look like a lot of hard metal, will clog the teeth of the metallographic grinding and polishing machine and cause failure, so it is very necessary to clean the metallographic grinding and polishing machine regularly. The purpose is to ensure conditions of use. - Replace main parts
Just don’t clean it frequently. In fact, the cutting parts of the metallographic grinding and polishing machine are very life-consuming. If not replaced, the life of the metallographic grinding and polishing machine will be consumed and the equipment will be completely scrapped. These things are things that companies don’t want to happen, so it is very important to regularly replace the cutting blades of the metallographic grinding and polishing machine.
Generally speaking, the production process of metallographic samples includes sampling, inlaying, touch grinding and polishing, corrosion, etc. Metallographic grinding and polishing machines are generally used for impact grinding, fine grinding and rough polishing. In order to make the sample have a relatively flat surface and remove parts with structural changes, the edges and corners of the sample can be smoothed and the observation surface can be smoothed. This is usually done on a grinder. Use steel. Fine grinding means removing some traces of the film. In order to make the surface smoother, sand is generally used to sand from coarse to fine, usually in a clockwise direction.
In the preparation process of metallographic samples, there are two very important processes, namely grinding and polishing, which are usually completed by two types of equipment, namely metallographic sample pre-grinding machine and metallographic sample polishing machine. The metallographic grinding and polishing machine consists of basic components such as a base, a polishing plate, a polishing cloth, a polishing cover, and a cover.
The motor is fixed on the base, and the taper sleeve that fixes the polishing disc is connected to the motor shaft through screws.
The polishing fabric is secured to the polishing pad via a ferrule. After the motor is energized via a switch on the base, the sample can be polished by hand on the rotating polishing pad. The polishing fluid added during the polishing process can flow into the square plate next to the polishing machine through the drain pipe in the plastic plate fixed on the base. The polishing cover and cover can prevent dust and other impurities from falling on the polishing cloth when the machine is not in use, affecting the use effect.
There are some tips for using metallographic grinding and polishing machines:
- When the grinding abrasive is squeezed from one cylinder to another, the constrained parts will produce a grinding effect. By adjusting the stroke position and preset honing times in advance, the parts will be ground, polished and rounded. The extrusion honing machine is simple to operate, easy to adjust and has multiple functions.
- Metallographic grinding and polishing machines are used to fix parts and fixtures in designated positions and apply a certain extrusion force to the abrasives. An extrusion honing machine has two opposing grinding cylinders that clamp parts or fixtures when closed.
When using a metallographic grinding and polishing machine to polish objects, you need to master some skills of the polishing equipment in order to give full play to the effectiveness of the equipment and maximize the efficiency of the equipment.
