Ukuchaneka kokuthwala kuqulathe ukuchaneka kunye nokuchaneka okujikelezayo komlinganiselo wokuchaneka yiprojekthi efakwa kwiishafts, ibandakanya ububanzi bangaphakathi, ububanzi bangaphandle, ububanzi, ukunyamezelana kobungakanani be-chamfer okanye ixabiso elivunyelweyo. Ukuchaneka kwejiyometri kubandakanya ukuphambuka kobubanzi, ukuphambuka okuphakathi kobubanzi bangaphakathi, ukuphambuka kobubanzi becala langaphandle, ukuphambuka okuphakathi kobubanzi bendandatho kwiplani enye yeradial. Ukuchaneka kokujikeleza kukujikeleza iPendulum, kubandakanya iringi yangaphakathi kunye nokujika kweradial yendandatho yangaphandle kunye nokubaleka kwe-axial, Icala leringi yangaphakathi kunye nobubanzi bangaphandle bomphezulu wokubambelela. Udidi lokuchaneka kokuthwala ukusuka kwibanga eliqhelekileyo 0 ukuya ku-6, 5, 4 kunye nebanga lesi-2, ngokulandelanayo, ngezantsi kukho uthelekiso lwetafile phakathi kweklasi ye-preeision ye-china GB 307 kunye neminye imigangatho yokuchaneka. Udidi olukhulu lokuchaneka kokuthwala luvela kwibanga lesi-6, 5, 4 kunye ne-2 lamanqanaba amane. 

Isangqa sangaphandle 11, isangqa sangaphakathi 12, kunye nebhola 13 eziqulathe izinto ezithwalayo yi-0.95 mass% okanye ngaphezulu kunye ne-1.10 mass% okanye ngaphantsi kwekhabhoni, i-0.05 mass% okanye ngaphezulu kwaye ingaphantsi kwe-0.3 mass% silicon, i-0.10 mass% okanye ngaphezulu kunye ne-0.50 mass% 11 A yeendlela zomdyarho zangaphandle kunye ne-12 A yeendlela zomdyarho zangaphakathi ezikumphezulu oqulathe intsimbi equlathe i-manganese elandelayo, i-1.30 mass% okanye ngaphezulu, kunye ne-2.00 mass% okanye ngaphantsi, kwaye yenziwe ngentsimbi equlathe isinyithi esiseleyo kunye nokungcola, kunye nokudibana nezinye izinto. Kwaye uxinaniso oluqhelekileyo lwenitrogen kwimimandla yomaleko womphezulu i-11B, 12B, kunye ne-13B eziziindawo ezikubunzulu be-20 μm ukusuka kumphezulu oqengqelekayo webhola i-13A yi-0.2% ngobunzima okanye ngaphezulu kunye ne-0.7% ngobunzima okanye ngaphantsi, kwaye kwimimandla yomaleko womphezulu i-11B, 12B, 13B, ii-carbides ezi-5 okanye ngaphezulu ezinobubanzi be-0.5 micrometer okanye ngaphantsi zikhona kwi-100 micrometer nganye.
