Which is better, manual or automatic?

Active polishing performance programming. Active is good "save trouble. Active polishing machine does not pick people. One-click start, configuration parameters are good. The sample can be ground well without much experience."
Many people believe that active metallographic polishing machines are easy to use. After starting the equipment, it can stop after a grinding process and place the sample on the fixture. After setting the parameters. Very easy.
Active metallographic polishing machine. The efficiency is also very high, and the equipped fixture can grind 6-10 samples at the same time. Programmable and repeatable. No matter how good it is for batch anti-replication samples, a rigid machine can be used by several private workers to manually grind this environment. It is not necessary to choose an active metallographic polishing machine.
But when the metallography of the test chamber clarified that the specific gravity of the materials is diverse. It cannot be prepared in batches, and it is all system-like. Moreover, when the samples of each day are new and non-repetitive, it is difficult for the active polishing machine to parry it. Why? Because for the first preparation of the sample, the grinding process is in the exploratory stage, and it is necessary to investigate while grinding. It is necessary to pick up the grinding effect from time to time to observe the grinding effect. This environment cannot be used for the full active metallographic polishing machine. Realized; if it is a manual / self-integrated metallographic polishing machine, it can't stop the rigid stop and stop turning. Due to the need of balance, the fixture has no measures to grind a single sample, so it needs to set up a balanced sample. The advantage of the machine is that there is no time to show it, and the redundant operation greatly reduces the preparation efficiency. Instead, it is more convenient to use a manual metallographic polishing machine!
Isn't manual inevitability better than active maneuver?
The manual metallographic polishing machine is convenient for the grinding specific force of a single sample. It is more active than manual. Conversely, experience accumulation is required for the operator. So for a batch anti-replication-like environment. The combination of manual and active.
Thanks to the metallographic polishing machine. Can also use active mode, also known as semi-active metallographic polishing machine. With manual grinding and polishing effect. It realizes the active functions of programming, storage, and one-click preparation. It combines the advantages of manual and active, and is also a model widely accepted.
Yunyun seems. There is no problem if the cost factor is not considered. It ’s not ok to directly choose a semi-active one? Of course it can.
And I always think about economic benefits. Regardless of your unit, the price is still a factor of tension. Cost saving is an eternal topic. Relatively speaking, the manual metallographic polishing machine has the lowest cost, followed by a semi-active one that costs more than half of the cost of a manual operation, and a full-active one that costs more than half of the cost.
