Scratch / gucukumbura nkibintu byo kwisiga byabonetse ku kirahure mugihe cyo gutunganya cyane. Hasi igipimo, giteye ubwoba. Porogaramu yihariye igena urwego rwiza kandi rukenewe. Cyane cyane, usobanura imiterere yububiko, agace ka gratches no gucukura.
Ibishushanyo- Igishushanyo gisobanurwa nkumurongo uwo ariwo wose "wajugunye" hejuru yikirahure. Urwego rwo gushushanya bivuga ubugari bwa scratch kandi bugenzure kubugenzuzi bugaragara. Ibikoresho byikirahure, gupfunga no gucana bikagira ingaruka kandi isura yicyuma murwego runaka.
Gucukura- Ubucukuzi busobanurwa nkurwobo cyangwa ikirahuri gito hejuru yikirahure. Impamyabumenyi yo gucukura igereranya ubunini nyabwo bwubucukuzi mu majana ya milimetero kandi igenzurwa na diameter. Diameter yubucukuzi budasanzwe ni ½ x (uburebure + ubugari).
Scratch / gucukura imbonerahamwe:
| Gushushanya / gucukumbura amanota | Scratch Max. Ubugari | Gucukura max. Diameter |
| 120/80 | 0.0047 "cyangwa (0.12mm) | 0.0315 "cyangwa (0.80mm) |
| 80/50 | 0.0032 "cyangwa (0.08mm) | 0.0197 "cyangwa (0.50mm) |
| 60/40 | 0.0024 "cyangwa (0.06mm) | 0.0157 "cyangwa (0.40mm) |
- 120/80 ifatwa nkurwego rwubucuruzi
- 80/50 nigipimo rusange cyemewe cyo kwisiga
- 60/40 ikoreshwa kubushakashatsi bwa siyansi
- 40/10
- 20/10 ni optic neza ubuziranenge
Sadya Grall ni ikirahuri cyemewe ku isi cyo gutunganya cyane mu buryo bwo gutunganya ubuziranenge, igiciro cyo guhatanira no igihe cyo gutanga. Hamwe nibirahure byifashe ahantu hatandukanye hamwe ninzobere mu kayira kegeranye, ikirahure cyaka, AG / AF / AF GAHIGO NUKO HALCOOR.
