Ba’zi zagotovkalarni mahkamlashga ketadigan vaqt frezalashga ketadigan umumiy vaqtning anchagina qismini tashkil etadi. SHu sababli ba’zi zagotovkalarni frezalashda havo yoki suyuqlik bilan ishlaydigan maxsus va tezsikar moslamalar ishlatiladi. Bu moslamalardan asosan ko’p seriyali va yalpi ishlab chiqarish korxonalarida foydalaniladi.
