countersinc

countersinc (prateekah ′) ack shankwakar chhed haye jise ack nirmit vastu mein kaataa jaataa haye, yaa cutter kaa upayog iss tarah key chhed koo kaatane key liye kiya jaataa haye. ack aam upayog yeh haye kii jaba ack countersank boult, screw yaa rivet key sir koo chhed mein rakhaa jaataa haye, tou aspas kii samagri kii satah key saath yaa usake neeche flush karane key liye baithane kii anumati dee jaati haye (tulanaa mein, ack counterboar ack sapaat-tala chhed banaata haye jiska upayog ack saaket-haid capscru key saath kiya jaa sakata haye). ack countersinc kaa upayog drilling yaa tapping operation seey bache hue barr koo hataane key liye bhee kiya jaa sakata haye jisase utpaad key anta mein sudhaar hotaa haye aur kissy bhee khatarnak tej kinaaron koo hataaya jaa sakata haye.
ack countersinc (cutter) kii mool jyaamiti koo swabhavik roop seey oopar varnit doobane vaale anuprayogon (kewal akshiya feed) aur anya milling anuprayogon (sideways traversal) parr bhee lagu kiya jaa sakata haye. isaliye, countersinc roop, kaary mein overlap hotey hain, aur kabhi-kabhi champhoring andmill (konn yukt tip key saath andmill) key saath naam bhee rakhate hain. cutter koo diye gaye naam kii parwah kiye binaa, utpann kii jaa rahee satah ack shankwakar champher (doobane vaale anuprayog) yaa dou vimaanon (paar karane vaale anuprayog) key pratichhedan key liye ack ghumaavdaar cona hoe sakati haye.
prakaar.
machining.
ack countersinc kaa upayog kaee upkaranon mein kiya jaa sakata haye, jaise kii abhyaas, abhyaas press, milling machine aur kharad.
cross-holl countersinc cutter.
ack cross-holl, "weldon shally" yaa "shoonya bansuri" countersinc ack shanku key aakar kaa upkaran haye jisamen ack chhed dwara pradaan kiya gayaa ack kaatane kaa kinara hotaa haye joe shanku key kinare seey gujarta haye. chhed aur shanku kaa pratichhedan upkaran parr cutting aij banaata haye. shanku vaastav mein samamit naheen haye kyonki yeh aavashyak haye kii shanku atyaadhunik seey door chaley jaae kyonki upkaran nikasi pradaan karate hue ghoomata haye. yadi aisaa naheen hotaa haye tou samagri mein "kaatane" key bajaay kinare parr safai aur ragad kii kamee hogi. iss nikasi koo cutting releaf kahaa jaataa haye.
inn upkaranon kaa sabse achchha upayog debering upkaranon key roop mein kiya jaataa haye, jahaan pichhale machining operation seey barr koo cosmetic aur suraksha karanon seey hataane kii aavashyakta hoti haye, haalaanki unakaa upayog ack pench key liye ack countersank chhed banaane key liye naram samagri (jaise lakadi yaa plastic) mein kiya jaa sakata haye.
bansuri vaalaa countersinc cutter.
bansuri vaale countersinc cutter kaa upayog ack drill kiye gaye chhed key pravesh dwaar mein ack bhaari champher pradaan karane key liye kiya jaataa haye. counter-sunn-haid pench key liye sahee baithane kii anumati dene yaa dusare machining operation jaise tapping key liye netritva pradaan karane key liye isaki aavashyakta hoe sakati haye. countersinc cutter chhah samanya konon key saath nirmit kiye jaate hain, joe 60°, 82°, 90°, 100°, 110° yaa 120° hotey hain, jinamen seey dou sabse aam 82° aur 90° hotey hain. countersank-haid screw joe ekikrit dhaage key maanak kaa paalan karate hain, unamen aksar 82° konn hotaa haye, aur joe screw iso maanak kaa paalan karate hain, unamen aksar 90° konn hotaa haye. poore aerospace udyog mein, countersank fastners kaa konn aamtaur parr 100° hotaa haye.
back countersinc.
ack "back countersinc", jise "antahsthaapit countersinc" key roop mein bhee jaanaa jaataa haye, ack dou tukade vaalaa countersinc haye jiska upayog kathin kshetron taka pahunchane key liye kiya jaataa haye. ack ghatak ack chhad haye jise workpeace mein maujooda chhed mein daala jaataa haye; doosara ghatak cutter haye, joe chhad seey judaa hotaa haye, yaa sthiti mein honey key baad usase baahar nikalata haye. yeh anya prakaar key "back-machining" key saath tulaniya haye, jaise kii back-spotfacing, back-boaring, back-counterbering, back-milling aur back-debering. aam vishay spindle faces seey workpeace key door kii or machining sanchaalan koo puuraa karna haye, joe ack "dusare operation" setup koo rokta haye. yeh kaee tarikon seey sthaapana key samay aur hatasha koo cumm kartaa haye. yeh naa kewal flipping over, safai, reclamping aadi koo rokta haye.lekin yeh kissy anya setup parr punah sthaapit karane kii pareshani key binaa (kadee mehnat key sanket key madhyam seey) pahale setup key datum key saath sahaj uchch ekagrata, samanantarta aur chaukorta kii anumati bhee dey sakata haye.
gati, feed aur gupshup seey bachana.
countersinc cutter seey kaatate samay aksar gupshup seey bachana mushkil hoe sakata haye. hamesha kii tarah machining mein, setup jitna chhota aur adhik kathor hoga, utanaa hii behtar hoga. behtar gunavatta vaale bansuri vaale countersinc cutter mein kabhi-kabhi aniyamit pitching parr bansuri (yaa cumm seey cumm ack bansuri) hoti haye. pitching mein yeh bhinnata kaatane key kinaaron key ack harmonic kriya sthaapit karane aur ack lahardaar satah chhodane kii sambhavana koo cumm curr detee haye. yeh satah kii lahar kaatane key kinaaron kii satah kii gati, samagri key prakaar aur lagu dabaav (yaa feed darr) parr bhee nirbhar karati haye; ack baar shuru honey key baad ise hataana mushkil hotaa haye. bahut halka feed gupshup key jokhim koo badhaata haye. kaee anya machining sanchalanon kii tarah, gupshup key liye ack uchit pratikriya gati koo cumm karna aur feed koo badhaana hoe sakata haye. drill press parr, sabse dheemi upalabdh spindle gati aamtaur parr sabse achchi hoti haye. ack parivartaniya-gati haath seey pakadane vaali shakti drill key saath, cumm spindle gati praapt karane key liye trigger koo halke seey nichoda jaataa haye.
achche gupshup-mukt parinam aamtaur parr haath seey countersinc karke praapt kiye jaa sakate hain (ack sanchaalit spindle mein upkaran koo chalaane key vipareet). dheemi gati aur samvedansheel feed gupshup koo rokte hain. ack chauthai inch-hakes shank key saath, countersinc cutter koo anukraman-bitt prakaar key pechkash handle key saath rakhaa jaa sakata haye.
countersinking kaa roop banaaen.
form countersinc, jise "dimping" key roop mein bhee jaanaa jaataa haye, ack countersinc haye joe ack sanrachana kii taakat koo badhaane key liye sheet metal mein banata haye kyonki kaee tukadon key countersinc ack saath ghonsale banaate hain. gathit countersinc key utpaadan key liye dou prakriyaaen hainh "sikka dimping" aur "sanshodhit trijya dimping". kaafee motee chaadar mein aise dimple koo binaa kissy pareshani aur sheet parr ack nutt koo welding karane key kharch key sheet parr ack dhaage vaalaa kathor bindu praapt karane key liye bhee tapp kiya jaa sakata haye. nirmaan kii iss shally koo aksar aadhunik gharelu upkaran design mein dekhaa jaataa haye, kyonki yeh utpaad koo cumm keemat parr honey detaa haye, aur jaba taka chaadar paryaapt motee hoe taba taka gunavatta achchi hoe sakati haye.
