The current era is full of challenges and opportunities, and you can always feel the crisis that comes upon you, because when you think you have done well, inadvertently, someone far ahead of you. No matter what industry you are in, you are being chased and driven forward. An invisible inertia force is pushing you forward for a moment without stopping, so we sigh: it's not easy to do anything! We, as metallographic engineers, also need to make samples quickly and well to meet the constantly increasing testing volume and the constantly improving quality requirements of inspection and testing. The key to preparing high-quality samples lies in the grinding and polishing steps, so metallographic polishing is not easy.

   To prepare high-quality metallographic samples, in addition to having extensive sample preparation experience, a better metallographic polishing machine is necessary. There is nothing to say about experience, it depends on practical accumulation and personal understanding. However, the choice of a better metallographic polishing machine depends on the method.


With the continuous innovation of material research and the continuous improvement of production and manufacturing processes, the quality of metallographic sample preparation, grinding and polishing has reached a nanoscale polished surface. Such metallographic sample surfaces are no longer satisfied by ordinary metallographic polishing functions. How can we choose a high-quality metallographic polishing machine?


The editor of Lianneng Metallography believes that methods can be used to collect information, screen reliable information, consult one by one, determine alternative solutions, conduct in-depth communication, conduct on-site inspections, and ultimately determine the plan for procurement.


Collect information: Collect supply information of metallographic polishing machines through various channels and methods, including internet, exhibitions, introductions from classmates and friends, etc.


Screening information: The editor believes that among all the information that is more direct and reliable, it is introduced by classmates and friends, followed by actual experiences at exhibitions, and again, it is network information. The network information is relatively complex and needs to be identified as true or false, so it is more time-consuming and laborious.


Consultation one by one: Sort out the screened information and register it, then search for the contact information of suppliers one by one for preliminary communication and consultation. During the consultation process, another batch of suppliers that do not meet the requirements can be eliminated through a pass, and the remaining ones can be treated as alternatives.


Determine alternative solutions: Further communication will be conducted with several suppliers as candidates to clarify their needs. Suppliers will make corresponding metallographic polishing machine selection, accessories, and consumables configuration plans based on specific needs. Compare and analyze the solutions of various companies horizontally, such as brand, application performance, technical parameter satisfaction, price, delivery time, payment period, warranty period, after-sales service, etc. It is better to select and determine around 3 solutions.


Deep communication: Further communicate with the suppliers one by one regarding these selected solutions, and the one that will ultimately impress you is the one you want to choose.


Finalize the plan through on-site investigation: Conduct a final confirmation of the plan that can move your heart more. Before confirmation, it is difficult to determine whether it is suitable for you without obtaining on-site inspection of the prototype and actual operating experience. Buying a metallographic polishing machine equipment is similar to buying a small car. Without actual experience, it is difficult to make a final judgment on whether it is suitable for you. After the final confirmation of the plan, price negotiations were conducted, and both parties reached a consensus. At this point, the purchase of a metallographic polishing machine has basically completed 80% of the workload, and the rest will be handed over to the procurement process.


Procurement: According to the agreed plan, price, delivery date, warranty period, and after-sales service with the supplier, sign the contract, pay the payment according to the contract, and the merchant delivers, installs, debugs, and operates normally according to the contract.


At this point, the task of purchasing a metallographic polishing machine is considered complete. Does it sound a bit complicated? Yes, it is difficult to achieve the desired outcome without these detailed steps when choosing a device with better quality. Usually, our metallographic engineers do technical work
