Qaadashada-macdanta ee 'Semi-Metallic' ee Qalabka Kala-baxa. Tilmaamaha ugu muhiimsan: 1. Qiimaha jaban. 2. Xadgudubka kuleylka sare. 3. Isu caabbinta wanaagsan. 4. Ku habboon xaaladaha xaaladaha xaaladaha culus ee khasabka ah.

1. Sanqadha, oscillation iyo xumaanta ayaa si fudud u keenta sanqadha isdaba joog ah, oo ay weheliso wakaalad rabshado wata.

4. Wadahadalka kuleylka sare iyo heerka kuleylka sare iyo kuleylka sare ayaa kululaynta kuleylka kululeeyaha caliper-ka iyo qaybahaas, ka dibna dardar geliya gabowga caliper-ka, shaabada bastoolka iyo soo celinta ilaha soo celinta. Tallaabada kuleylka sare ayaa si fudud sababa jahwareerka kuleylka iyo heerkulka heerkulka sare ee xogta is khilaafsan, kaas oo sababi doona dahaarka jajaban ee lagu dhaco ama jebiyo.

5. Adhesion adag, oo aan sahlanayn inuu miridhku yahay. Dhiirrigelinta ka dib, cufnaanta ama waxyeelada waa laba lakab, oo xidhashada ayaa sii xumaanaya.
