Zvinhu zve thread
Tambo yacho inosanganisira zvinhu zvishanu: chimiro, dhayamita yezita, nhamba yemitsara, pitch (kana lead), uye gwara rekutenderera.cnc machining chikamu
1. rudzi rwezino
Chimiro chechidimbu cheshinda chinodaidzwa kuti chimiro chechimiro panzvimbo yechikamu ichipfuura nepakati peakisi yeshinda. Kune katatu, trapezoid, zigzag, denderedzwa arc uye rectangle.
Thread profile kuenzanisa:

 

 
2. Diameter

Kune dhayamita hombe (D, d), dhayamita yepakati (D2, D2), dhayamita diki (D1, D1) mushinda. Iyo dhayamita yezita idhayamita inomiririra saizi yeshinda.

Iyo dhayamita yezita yeshinda yakafanana ndiyo dhayamita huru.cnc kutendeuka chikamu

 

 
Shinda rekunze (kuruboshwe) mukati (kurudyi)

 
3. nhamba yemutsara
Tanda inoumbwa nehelix imwe inodaidzwa kuti tambo imwe chete, uye shinda inoumbwa nemahelikisi maviri kana anopfuura akagovaniswa zvakaenzana paaxial direction inodaidzwa kuti multi line thread.
Single

shinda (kuruboshwe) shinda mbiri (kurudyi)anodizing aluminium chikamu

4. Pitch uye mutungamiri
Pitch (P) chinhambwe cheaxial pakati pemapoinzi maviri anowirirana pamutsetse wedhayamita yemeno maviri ari padyo.
Lead (PH) chinhambwe cheaxial pakati pemazino maviri akabatana pahelix imwechete uye mapoinzi maviri anoenderana pamutsetse wedhayamita.
Pashinda imwe chete, lead = pitch; kune shinda dzakawanda, lead = pitch × nhamba yeshinda.

 
5. kutenderera nzira
Shinda inopindirwa kana ichitenderedzwa newachi inonzi shinda yekurudyi;
Shinda inopindirwa kana ichitenderedzwa newachi inonzi shinda yekuruboshwe.
