Uchazwa njani "uchaneko" kwisikhokhelo somgca?

Ukuchaneka kwenkqubo kaloliwe yomgca ngumbono obanzi, sinokwazi malunga nayo kwiinkalo ezintathu ngolu hlobo lulandelayo: ukuhamba ngokuhambelanayo, ukungafani kobude kwizibini kunye nokwahlukana kobubanzi kwizibini.

Ukuhamba ngokunxuseneyo kubhekiselele kwimpazamo yokunxulunyaniswa phakathi kweebhloko kunye neplani yedatum kaloliwe xa iibhloko ezithwele umgca zisebenza kubude obupheleleyo beereyili xa isikhokhelo somgca sigxininiswe kwinqwelomoya yedatum ngebholithi.
Umahluko wobude ngokwezibini ubhekiselele kobona bukhulu kunye nobuncinane bobude bemilinganiselo yeebhloko zesikhokelo ezinqamlezileyo ezidityaniswe kwinqwelo-moya efanayo yedatum.

Umahluko wobubanzi ngokwezibini ubhekiselele kumahluko phakathi kobukhulu kunye nobungakanani bobungakanani bobubanzi obuphantsi kwibhloko yesikhokelo somgca ngamnye kunye nelayini yesikhokelo somzila wenqwelomoya yedatum efakwe kumzila kaloliwe omnye.

Ngoko ke ukuchaneka kwesikhokelo somgca kwahlulwa kwixabiso lezalathi ezininzi: isibonelelo sobude bobude H, umahluko wobude ngokwezibini ukuba ubude H, isibonelelo sobukhulu bobubanzi W, umahluko wobubanzi kwizibini zobubanzi W, ukuhambelana kokuhamba komphezulu ongaphezulu. yebhloko yesilayidi ehambelanayo ukuya kumphezulu ongezantsi wesilayidi sesilayidi, ukuhamba ngokuhambelana kwendawo esecaleni yebhloko yesilayidi ukuya kumphezulu wecala lomzila wesilayidi, kunye nokuchaneka komgca wobude bomzila wesikhokelo somgca.

Ukuthatha umzila wesikhokelo somgca we-1000mm njengomzekelo, ukuchaneka kwesikhokelo somgca we-PYG kuyafana ne-HIWIN, eyahlulahlulwe kwiklasi ye-C eqhelekileyo 25μm, iklasi ye-H ephezulu 12μm, iklasi ye-P echanekileyo 9μm, iklasi ye-ultra-precision SP 6μm, i-ultra -echanekileyo UP iklasi 3μm.

Udidi lweC~P lwezikhokelo zePYG zinokuhlangabezana ngokupheleleyo nezixhobo zoomatshini eziqhelekileyo, kwaye iklasi ye-SP kunye nezikhokelo ze-UP zilungele ngakumbi izixhobo zesayensi kunye nezobuchwepheshe kunye nezixhobo.Ngaphandle koko, ngokwembono yesicelo, ukuchaneka kwezikhokelo zomgca kwakhona kugqitywe ngokuqina kwezinto, ibakala lokulayishwa kwangaphambili kunye nokunye.
