Note
When using a belt sander for sample pretreatment, follow the
instructions below.
● Use the belt sander dry.
● Regularly replace the belt sander. If the belt is worn, samples
cannot be polished properly, which results in lower analytical
accuracy.
●
Regularly replace the backing plate of the belt sander.
If an old backing plate is continuously used, flatness of the polished
sample surface becomes poor, which may result in argon gas
leakage and unstable discharge.
Note
When using a lathe for sample pretreatment, follow the instructions
below.
● Regularly clean the lathe.
● Regularly grind or replace the turning tool of the lathe. If the tool is
worn, flatness of the ground sample surface becomes poor.
●
When a lubricant is necessary for grinding samples, use ethanol. Do
not use grinding oil for machining or methanol.
Using machine oil may cause abnormal discharge.
●
If machine oil or other oil sticks to a sample, clean it with ethanol.
Do not use methanol.
