Kwa nini vifaa vya sahihi vinavyotengeneza vifaa vinavyotumiwa? Lengo kuu la uchimbaji ni mara mbili. Kwanza, inaweza kuongeza mwangaza wa moli na kuboresha mtazamo wa kimapenzi wa kazi hiyo. Pili, inaweza kufanya vifaa rahisi kujenga demokrasia.Baadae, EMAR itachukua kuelewa njia za sera za kawaida za kuendelea kwa urahisi.

1. Mechanical polishing: Mechanical polishing is a method of polishing a smooth surface by removing the convex parts after polishing through deformation processes such as cutting precision stamping molds and plastic deformation of material surfaces. For precision stamping workpieces with high surface quality requirements, ultra precision polishing can be used. Ultra precision polishing uses specially designed grinding tools, which are pressed tightly against the surface of the workpiece to be processed in a polishing solution containing abrasives, and perform high-speed rotational motion.

2. Electrolytic polishing: Precision stamping molds can be smoothed by removing small protrusions on the material surface through electrolytic polishing. Compared with chemical polishing, it can eliminate the influence of cathodic reactions and achieve better results.

3. Ultrasonic polishing: Place the material to be polished into a grinding suspension and place it together in an ultrasonic field. Then, through the oscillation of ultrasonic waves, the abrasive is ground and polished on the surface of precision stamped workpieces. Utafiti wa Ultrasonic una nguvu ndogo ya kikosi na haitasababisha mabadiliko ya kazi hiyo, lakini utafanya uzalishaji na kuweka vifaa vinavyostahili vigumu zaidi. Utafiti wa Ultrasonic unaweza kuunganishwa na njia za kemikali au umeme. Kutokana na uchunguzi wa ufumbuzi na umeme, ukatili wa umeme unatumiwa kuitengeneza suluhisho hilo, na kusababisha bidhaa zilizovunjwa juu ya upande wa kazi ili kutenganisha na korozo au elektrolyt karibu na uso wa juu kuwa uniform; Matokeo ya ukatili ya mlima katika maji yanaweza pia kuzuia mchakato wa mafuta, ambao unafaa kwa mwangaza wa umeme wa kazi zilizopangwa.
