When it comes to the selection of metallographic polishing machines, it is widely believed subconsciously that automatic ones are better than manual ones.

&Ldquo; Automatic polishing machine programming, effortless, automatic and good&rquote;

&Ldquo; The automatic polishing machine does not pick people, sets the parameters well, and can be started with just one click. It can grind the sample well without too much experience;

Many people firmly believe that automatic metallographic polishing machines are easy to use and place specimens on fixtures. After setting the parameters, start the equipment and it will automatically stop after a process is completed, which is very convenient.

The automatic metallographic polishing machine is equipped with a fixture that can simultaneously grind 6-10 samples, with very high efficiency, programmability, and good repeatability. It is perfect for batch repeated sample preparation, as one machine can handle several manual grinding operations. In this case, an automatic metallographic polishing machine must be selected.

However, when the metallographic analysis materials in the laboratory are relatively diverse and all are individual sample preparation, batch preparation cannot be used, and every day the samples are new and do not have repeatability, the automatic polishing machine is difficult to resist. Why? Because for the first prepared sample, the grinding process is in the exploratory stage and needs to be observed while grinding. During the grinding process, it is necessary to occasionally pick up and visually inspect the grinding effect. This situation cannot be achieved with a fully automatic metallographic polishing machine; If it is a manual/self integrated metallographic polishing machine, it cannot avoid the machine stopping and rotating. Due to the need for balance, the fixture cannot grind a single sample and needs to be equipped with a balanced sample, which is more time-consuming and labor-intensive. The advantages of an automatic polishing machine are not fully utilized, and redundant operations greatly reduce the preparation efficiency. On the contrary, it is not as convenient as using a manual metallographic polishing machine!

Is manual definitely more flexible than automatic?

The manual metallographic polishing machine is relatively flexible and useful for grinding individual specimens, but it requires experience accumulation for the operator. Therefore, for the case of batch repeated sample preparation, automatic is more suitable than manual. On the contrary, manual is more suitable than automatic.

Fortunately, a hand/self integrated metallographic polishing machine, also known as a semi-automatic metallographic polishing machine. It has both manual grinding and polishing functions and can use automatic mode to achieve automatic functions such as programming, storage, and one click preparation. It combines the advantages of manual and automatic, and is also a widely adopted model.

So, is it okay to just choose a semi-automatic one? Of course, there is no problem without considering the price factor.

And we often consider economic benefits, and price is still a relatively important factor. No matter what unit you are, cost saving is an eternal topic. Relatively speaking, manual metallographic polishing machines have a lower price, followed by semi-automatic ones that are about half higher than manual ones, and fully automatic ones that are more than half higher.

Seeing this, I believe you already know that both manual and automatic metallographic polishing machines have different applications and their respective focuses. Different types of equipment are designed to meet different user needs, and for different applications, what is more suitable is better. If you are a production enterprise and need to repeatedly prepare metallographic samples in large quantities every day, it is recommended to choose fully automatic; If you are a school student interning, it is recommended to choose manual mode; If you are an ordinary user, you can consider semi-automatic. Simply put, what is more suitable for you to use, can bring convenience to your work, and improve economic efficiency is better.
