Thaum broaching zoo tib yam structural steel thiab cam khwb cia hlau, lub roughing ceev yog feem ntau 3-7 m / min, thiab cov tiav broaching ceev yog tsawg tshaj li 3 m / min. Rau qhov nyuaj-rau- tshuab hlau xws li siab- kub alloys lossis titanium alloys, cov txiaj ntsig txaus siab tsuas yog tuaj yeem tau los ntawm kev siv cov cemented carbide lossis siab tshiab -ceev steel broaches ntawm lub tshuab high-speed broaching nrog zoo rigidity ntawm speeds ntawm 16-30 m / s. Siv cov khoom siv helical broaching, qhov twg lub helical broach thiab workpiece undergo tus txheeb ze linear thiab rotary motion, internal threads, helical spline qhov, thiab helical internal zog kuj yuav broached.
Broaching feem ntau siv cov kua txiav nrog cov khoom zoo lubrication, xws li txiav cov roj thiab cov emulsions siab heev. Thaum lub sij hawm siab - ceev broaching, lub txiav kub yog siab, thiab tshuaj txiav cov kua thiab emulsions nrog zoo txias zog yog feem ntau xaiv. Yog tias siv cov broach txias sab hauv, cov kua txiav yog txhaj rau hauv qhov siab siab rau hauv txhua lub nti zawj ntawm lub broach, uas muaj cov txiaj ntsig zoo ntawm kev txhim kho saum npoo zoo, txo cov cuab yeej hnav, thiab ua kom cov khoom ua tau zoo.
