Biirta rogrogmada waa qaybo muhiim ah oo si weyn loogu isticmaalo injineernimada farsamada, waxqabadkooduna si toos ah ayuu u saameeyaa isku halaynta hawlgalka ee mashiinka oo dhan. Tijaabada adkaanta ee qaybaha rogrogmada waa mid ka mid ah tilmaamayaasha lagu hubinayo waxqabadka iyo badbaadada. Heerarka Caalamiga ah ee ISO 6508-1 "Hababka Tijaabada Adkaanta Qaybaha Rogidda" waxay qeexayaan shuruudaha farsamo ee tijaabada adkaanta qayb, oo ay ku jiraan waxyaabaha soo socda:
1. Shuruudaha adag ee qaybaha qaadista ka dib marka la kululeeyo;
1) Birta chromium-ka ee kaarboon sare leh (taxanaha GCr15):
Adkaanta ka dib marka la kululeeyo waxaa badanaa loo baahan yahay inay ku jirto 60 ~ 65 HRC (cabirka adag ee Rockwell C);
Adkaanta ugu yar waa inaysan ka hooseyn 60 HRC; haddii kale, iska caabbinta xirashadu ma ku filnaan doonto, taasoo horseedaysa xirasho hore;
Adkaanta ugu badan waa inaysan ka badnaan 65 HRC si looga fogaado jajab xad dhaaf ah oo ku yimaada walxaha, taasoo keeni karta jabka marka culayska la saaro.
2) Qalabka loogu talagalay xaaladaha shaqada ee gaarka ah (sida birta la shiiday ee la shiiday, birta la shiiday ee heerkulka sare leh):
Birta la shito ee kaarbooraysan (sida 20CrNiMo): Adkaanta lakabka kaarbooraysan ka dib marka la kululeeyo guud ahaan waa 58 ~ 63 HRC, adkaysiga xuduntana waa mid hooseeya (25 ~ 40 HRC), taas oo dheellitirta iska caabbinta dusha sare iyo adkaysiga xudunta;
Birta heerkulka sare leh (sida Cr4Mo4V): Ka dib marka lagu kululeeyo jawi heerkul sare leh, adkaanta badanaa waxay ku sii jirtaa 58 ~ 63 HRC si ay u buuxiso shuruudaha iska caabbinta xirashada heerkulka sare.
2. Shuruudaha adag ee qaybaha qaadista ka dib marka la kululeeyo heerkulka sare;
200°C Raceway 60 – 63HRC Steel Ball62 – 66HRC Roller61 – 65 HRC
225°C Raceway 59 – 62HRC Steel Ball62 – 66HRC Roller61 – 65 HRC
250°C Raceway 58 – 62HRC Steel Ball58 – 62HRC Roller58 – 62 HRC
300°C Raceway 55 – 59HRC Steel Ball56 – 59HRC Roller55 – 59 HRC
3. Shuruudaha aasaasiga ah ee muunadaha la tijaabiyay ee tijaabada adag, iyo sidoo kale qeexitaanno kala duwan oo tijaabo ah sida xulashada hababka tijaabada adag, xoogga tijaabada, iyo booska tijaabada.
1) Tijaabooyinka tijaabada adag ee Rockwell: 60kg, 100kg, 150kg (588.4N, 980.7N, 1471N)
Kala duwanaanshaha awoodda tijaabada ee tijaabiyaha adag ee Vickers waa mid aad u ballaaran: 10g ~ 100kg (0.098N ~ 980.7N)
Xoogga tijaabada ee tijaabada adag ee Leeb: Nooca D waa qeexitaanka ugu ballaaran ee loo isticmaalo xoogga tijaabada (tamarta saameynta), oo ku habboon inta badan qaybaha birta caadiga ah
