Yuav Ua Li Cas Xaiv Ntawm Indexable thiab Khoom Carbide Drills rau Stainless

Stainless hlauua hauj lwm-hardening nyiam thiab abrasive chips xav tau xyaum ua kom sib npaug hnav tsis kam thiab kub dissipation. Thaum indexable xyaum ua tus thawj coj kev lag luam hnyav rau lawv cov kev hloov pauv tau, cov khoom sib txawv carbide yog nyiam rau aerospace-qib precision. Qhov kev tshawb fawb xyoo 2025 no hloov kho cov qauv xaiv nrog cov ntaub ntawv hauv ntiaj teb tiag tiag los ntawm 304L thiab 17-4PHstainless hlau machining.

Xeem Tsim

1.Khoom siv:304L (annealed) thiab 17-4PH (H1150) stainless hlau daim hlau (thickness: 30mm).

2.Cov cuab yeej:

●Indexable:Sandvik Coromant 880-U (ϕ16mm, 2 inserts).

●Khoom carbide: Mitsubishi MZS (ϕ10mm, 140 ° taw tes lub kaum ntse ntse).

●Parameters:Tsis tu ncua pub (0.15mm / rev), coolant (8% emulsion), ntau yam ceev (80-120m / min).

Cov txiaj ntsig & Kev Ntsuam Xyuas

1.Tool Lub Neej

●Khoom carbide:Ntev 1,200 qhov hauv 304L (flank hnav ≤0.2mm).

●Indexable:Yuav tsum tau hloov pauv txhua 300 qhov tab sis raug nqi 60% tsawg dua rau ib lub qhov.

2 .Nto tiav

 Khoom carbide ua tiav Ra ​​1.6µm vs. indexable's Ra 3.2µm vim txo qhov khiav tawm.

Kev sib tham

1.Thaum xaiv Khoom Carbide

●Cov ntawv thov tseem ceeb:Cov cuab yeej kho mob, nyias phab ntsa drilling (vibration-sensitive).

●Cov khoom me me:Tsis txhob tso cov nqi khoom muag.

2.Kev txwv

Kev ntsuam xyuas tsis suav nrog qhov tob tob (> 5 × D) xwm txheej. High-sulfur steels tuaj yeem nyiam cov khoom siv coated.

Xaus

Rau stainless hlau:

●Khoom carbide:Qhov zoo tshaj plaws nyob rau hauv 12mm txoj kab uas hla los yog nruj tolerances.

●Indexable:Kev lag luam rau ntau lawm khiav> 500 qhov.

Kev ua haujlwm yav tom ntej yuav tsum tshawb nrhiav cov cuab yeej hybrid rau hardened steels.
