Qog'oz kesgichni nam yoki changli muhitda ishlatishdan qochish kerak va har oy harakatlanuvchi qismlarga oz miqdorda moylash moyi qo'shilishi kerak. Agar foydalanish to'xtatilgan bo'lsa, zangni oldini olish uchun yuqori va pastki pichoqlar oz miqdorda zangga qarshi moy bilan qoplangan bo'lishi kerak.
The new blade equipped with the A4 paper cutter needs to be used after it has been sharpened. Sometimes the new knife that has just been sharpened will have a phenomenon of incision pulling when cutting. Many people think that it is a knife flower. In fact, this is a cognitive phenomenon. Misunderstanding, because this kind of pull flower phenomenon will disappear naturally with the increase of cutting amount. It is observed through magnification that this is caused by the adhesion of steel chips after grinding to the blade, which is usually called a burr. The burr will automatically fall off with the continuous movement and friction of the blade, which is essentially different from the blade. Therefore, after the grinding is completed, in order to make the cutting edge sharper and smoother, the cutting blade should be sharpened with a whetstone after sharpening, and then a bamboo piece (wood block or plastic can also be used) to keep the blade along the cutting edge. The granular burrs on the blade are scraped off, and at the same time, oil (anti-rust) is applied to the blade to prolong the service life of the blade and make the cut edge smoother. If it is found in the cutting work that there is a blade pulling the paper on some cutting surfaces, it should be polished with a whetstone at any time.
Bir tomondan, pichoqning sifati va undan foydalanish oqilona bo'ladimi, to'g'ridan-to'g'ri kesish sifatiga ta'sir qiladi. Boshqa tomondan, asossiz o'tkir burchak va foydalanish qog'oz kesgichning aniqligi va ishlash muddatiga jiddiy zarar etkazadi. Bu tafsilot masalasiga o'xshaydi, lekin agar u noto'g'ri qo'llanilsa, bosma mahsulotlarning sifati va ishlab chiqarish samaradorligiga chuqur ta'sir qiladi va yuqori baholanishi va e'tiborga olinishi kerak.
