Wakati wa matumizi ya Mkanyagia Raymond, hakuna mafuta ya kulainisha au mafuta ya kulainisha ambayo yanaongezwa kwa muda mrefu, lakini mchakato wa kuchagua mafuta ya kulainisha au mafuta ya kulainisha sio sahihi. Ikiwa ujazo hauwekwa vizuri, mashine itaharibiwa, na uvunjifu wa kuzaa na usakinishaji hautakuwa sawa. Roller ya kusaga inatetema nje, ikisisitiza dhidi ya
     
Shimo kubwa, lililojaa, huitwa tundu la upungufu. Eneo hilo linaitwa osteoporosis, ambalo ni dogo na limetawanyika. Uso wake wa ndani ni mgumu na kuna uchafu mwingi na vinyweleo vidogo kuzunguka. Kwa sheria ya upanuzi na kupungua kwa joto, upungufu ni jambo lisilopingika, ukubwa na eneo, au linapoenea kwenye ingot, ni kasoro katika kitu hicho. Ili kuzuia kasoro hizi kutokea mapema, tunaweza kuzizuia kabisa chanzo chake.
     
Mkanyagia Raymond's grinding roller grinding ring fails to escape the gas during metal solidification process. The metal is formed in a small hole, the ultrasonic wave has a high reflectivity, and because of its substantially spherical or elliptical shape, the porosity of the steel ingot is forged. Or after rolling, it is flattened into area type defects and found to benefit from ultrasonic testing. Ultrafine grinding of the grinding ring during the reaction of the grinding ring, or the addition of some components of the metal parts of the material to form incompletely molten metal inclusions, such as high density, high melting point, such as tungsten, molybdenum.
