Cov ntsia hlau me me yog cov khawm me uas txuas cov khoom lag luam nrog cov ntawv me me, tab sis nws ua lub luag haujlwm tseem ceeb hauv kev txuas cov ntu tseem ceeb. Dav dav siv hauv tshuab hluav taws xob, hluav taws xob, khoom siv hluav taws xob, rooj tog, khoom siv tshuab thiab lwm yam.
Precision screws xav tau hardened.
Kev nruj ntawm precision screws ntawm cov khoom lag luam feem ntau ua tiav. Vim tias ntau qhov unscrewed precision screws yooj yim plam lossis tawg thaum siv. Qhov laj thawj tseem ceeb tshaj plaws rau kev plam thiab tawg xov yog tias lub siab tsis ncaj screws tsis nyuaj. Yog li no, qhov ntsuas screws nrog hardness yuav tsum muaj zog.
Cov khoom siv sib txawv precision ntsia hlau.
Precision screws yog ua los ntawm carbon hlau thiab stainless hlau. Carbon steel precision screws feem ntau yog ua los ntawm cov hlau tsis muaj steel, thiab cov ntaub ntawv yog cov carbon hlau tsawg, nruab nrab carbon hlau thiab siab carbon steel. Cov khoom siv hlau ntsia hlau yog 1010 A, 1018, 10 B 21, 45 hlau, thiab lwm yam.
Stainless hlau precision screws feem ntau yog ua los ntawm cov xov hlau tsis muaj steel. Nws cov khoom siv yog cov kab xeb hlau 201, stainless hlau 304, stainless hlau 410, stainless hlau SUS 316, stainless hlau SUS 404 thiab lwm yam.
Precision ntsia hlau plating yog txawv.
Kev electroplating ntawm precision screws feem ntau hais txog carbon hlau precision screws, thaum hlau stainless precision screws feem ntau tsis xav tau electroplating tsuas yog thov los ntawm cov neeg siv khoom.
Precision ntsia hlau plating raug faib ua kev tiv thaiv ib puag ncig thiab kev tiv thaiv ib puag ncig.
