Metallographic sample preparation is relatively difficult in the grinding and polishing process, so what methods can pulse detection have for metallographic grinding and polishing? The following three points are included in the minor part.


1. Qmaxis believes that selecting the appropriate diamond grinding disc and metallographic abrasive paper in the coarse grinding stage, together with the correct grinding scheme, can be improved

Qmaxis diamond grinding disc has high removal rate and good edge retention effect. It is particularly suitable for the sample surface of hard materials such as cemented carbide, thermal spraying coating and ceramics. It can not only reduce the grinding steps and sample preparation time, but also is more economical than using other grinding consumables. Therefore, it is very appropriate to select diamond grinding disc for the sample of this kind of hard material. Qmaxis provides flexidgd flexible diamond grinding disc with magnetic backing and metdgd metal bonded diamond grinding disc with adhesive backing.


Qmaxis silicon carbide metallographic abrasive paper carbipaper has uniform and dense particle distribution of grinding medium, strong paper-based toughness, good water resistance, high removal rate, less scratch and damage, and effectively shortens the sample preparation time. Complete specifications and models can meet various grinding requirements for metallographic sample preparation. For materials with general hardness, the grinding effect is very significant.


Therefore, in the coarse grinding stage of metallographic samples, it is better to use silicon carbide metallographic abrasive paper for general hard materials, while diamond grinding disc is more suitable for high hardness materials such as cemented carbide. Combined with the characteristics of sample materials and practical experience, it is very easy to improve the grinding effect by adopting a more appropriate grinding scheme.


2. According to pulse detection, it can be improved by selecting appropriate metallographic polishing fluid, polishing powder and appropriate polishing cloth in the polishing stage

Qmaxis diamond polishing fluid, a high-quality diamond polishing agent, is an ideal polishing consumable for metallographic polishing. It not only has high removal rate, good polishing effect, but also is environmentally friendly and non-toxic. It is a very good choice for manual polishing and automatic polishing. Polycrystalline and single crystal; Water based and oil-based, with high concentration of concentrated solution and diluent added with lubricant, it can meet various application requirements and is suitable for grinding and polishing of various materials.

Qmaxis aluminum oxide and silicon oxide polishing fluid for final polishing are nano scale high-quality oxide polishing materials. They are the polishing agents used for the final polishing of metallographic samples. They can remove finer scratches on the surface of samples, obtain ideal mirror polishing effect, and accurately reproduce the microstructure of materials.

Of course, in addition to aluminum oxide and silicon oxide polishing fluid, some materials are also quite good choices for final polishing with aluminum oxide polishing powder. Qmaxis provides agglomerated alumina polishing powder and non agglomerated alumina polishing powder to meet different polishing requirements.

With these polishing fluids, polishing powders and other metallographic polishing agents, you still lack metallographic polishing cloth, which can be used with the metallographic polishing agent you choose. Qmaxis metallographic polishing cloth is made of nylon, natural silk, man-made fiber, velvet and other materials with adhesive backing. It has a variety of knitting methods such as cashmere, short staple and long staple. It is suitable for various high-quality polishing fabrics with rough polishing, intermediate polishing and final polishing. It helps the polishing agent to play its high removal rate and obtain a very good surface finish. It is suitable for surface polishing of various materials. Compared with similar products, it has long service life and high cost performance.


It is very easy to improve the grinding effect by using good polishing liquid or polishing powder, with these high-quality metallographic polishing cloth, holding the grinding medium particles, and using a more appropriate grinding scheme.

3. According to the pulse detection, reasonable use of polishing cooling lubricant to assist polishing will also improve

Qmaxis polishing cooling lubricant, diafluid water-based and oil fluid oil-based polishing cooling lubricant, which is applied to the metallographic grinding and polishing process, is added to the polishing agent to play the role of cooling and lubrication, effectively reduce the damage of grinding and polishing medium particles to the material surface, improve the polishing effect, and is suitable for all kinds of materials. Water based materials are used for materials that are not sensitive to water, while oil-based materials are used for materials that are sensitive to water. They are auxiliary products of metallographic polishing agents. It is very helpful to improve the polishing effect by rational use of polishing cooling lubricant. Therefore, rational use of polishing cooling lubricant to assist polishing will also be improved.


No matter how hard it is to prepare samples, these metallographic polishing products can also be used to improve! No matter how good the idea of pulse detection is, it is better to test it with practice. Only after the test of practice can it be trusted. Pulse testing Nanjing laboratory provides imported metallographic equipment and qmaxis metallographic consumables, which can be tried for free. Bring your hard to prepare samples to the laboratory for on-site preparation. In order to make an appointment for you as soon as possible, please contact the pulse detection engineer now!
