Nto Roughness nyob rau hauv ntau yam txheej txheem txiav

Deg roughness yog hais txog qhov tsis sib xws thiab sib txawv hauv qhov kev ntxhib los mos ntawm cov khoom tom qab nws tau raug rau kev txiav. Nws yog ib qho tseem ceeb parameter uas ncaj qha cuam tshuam rau functionality, durability, thiab zoo nkauj txaus siab ntawm cov khoom kawg. Ua kom tiav qhov xav tau qhov roughness yog qhov tseem ceeb rau kev ua kom haum, txo kev sib txhuam, thiab txhim kho tag nrho cov kev ua tau zoo ntawm cov khoom siv machined.

1. tig

Tig yog txheej txheem machining qhov twg lub workpiece rotates thaum lub cuab yeej txav linearly los yog ua raws txoj kev nkhaus nyob rau hauv ib lub dav hlau los txiav cov khoom. Qhov kev ua haujlwm no feem ntau ua rau ntawm lub tshuab dhos rau tshuab sab nraud thiab sab hauv cylindrical nto, kawg ntsej muag, conical nto, tsim nto, thiab threads.

Qhov kev ntxhib los mos ntawm qhov chaw ua haujlwm yog los ntawm Ra 1.6 txog 0.8 μm.

• Rough tig lub hom phiaj kom ua tiav kev ua haujlwm siab los ntawm kev siv qhov tob tob ntawm kev txiav thiab pub tus nqi yam tsis txo qhov kev txiav ceev, uas ua rau qhov roughness ntawm Ra 20 txog 10 μm;
• Semi-tiav thiab ua tiav txoj siav siv kev nrawm dua nrog cov nqi me me thiab qhov tob ntawm kev txiav, ua tiav qhov roughness ntawm Ra 10 txog 0.16 μm;
• High-precision lathes nrog finely honed pob zeb diamond cov cuab yeej tuaj yeem tsim cov hlau tsis muaj hlau nrog qhov roughness ntawm Ra 0.04 txog 0.01 μm thaum lub sijhawm ua haujlwm siab ceev.

2. Milling

Milling suav nrog kev siv lub tshuab sib hloov ntau lub tshuab kom tshem tawm cov khoom siv los ntawm kev ua haujlwm, muab txoj hauv kev zoo rau kev siv lub dav hlau, grooves, ntau qhov chaw tsim (xws li splines, zog, thiab xov), thiab cov duab tshwj xeeb ntawm cov pwm. Nyob ntawm seb qhov kev taw qhia thawj qhov kev tshaj tawm qhov sib tw los yog tawm tsam cov khoom noj khoom noj, milling tuaj yeem raug cais raws li cov pa (nce) milling lossis nce (down) milling.

Hom milling nto roughness txawv ntawm Ra 6.3 txog 1.6 μm.

• Rough milling ua rau qhov roughness ntawm Ra 5 txog 20 μm;
• Semi-finishing milling ua tiav qhov roughness ntawm Ra 2.5 txog 10 μm;
• Kev ua tiav milling yields nto roughness ntawm Ra 0.63 mus rau 5 μm.

3. Sib tsoo

Sib tsoo yog txheej txheem machining precision uas siv cov nplej abrasive lossis cov cuab yeej tshem tawm cov khoom siv ntau dhau los ntawm cov khoom ua haujlwm, dav siv hauv kev tsim khoom siv tshuab.

Kev sib tsoo feem ntau yog siv rau kev ua haujlwm ib nrab thiab ua tiav, nrog rau qhov chaw roughness xws li Ra 1.25 txog 0.16 μm.

• Precision sib tsoo ua rau qhov roughness ntawm Ra 0.16 txog 0.04 μm;
• Ultra-precision sib tsoo tuaj yeem ua tiav qhov roughness ntawm Ra 0.04 txog 0.01 μm;
• Lapping lossis polishing tuaj yeem ua rau saum npoo tiav zoo dua Ra 0.01 μm.

Qhov saum npoo roughness ntawm machined Cheebtsam muaj qhov cuam tshuam loj heev rau kev tsim khoom thiab engineering industries. Nws cuam tshuam ncaj qha rau kev ua haujlwm, kev ua haujlwm, thiab kev ntseeg siab ntawm cov khoom siv tshuab, cov cuab yeej, thiab cov khoom siv. Los ntawm kev nkag siab txog kev sib raug zoo ntawm cov txheej txheem txiav thiab nto roughness, engineers thiab manufacturers tuaj yeem ua kom zoo dua lawv cov txheej txheem ntau lawm, txo cov khoom pov tseg, thiab xa cov khoom zoo tshaj plaws rau kev ua lag luam.
