CNC tshuab cuab tam guideways yog ib feem tseem ceeb ntawm kev txhawb nqa thiab taw kev txav ntawm cov cuab yeej siv tshuab. Lawv hom thiab cov yam ntxwv cuam tshuam ncaj qha rau machining raug, efficiency thiab stability. Raws li kev sib txhuam cov khoom thiab cov qauv, cov lus qhia kev tsheb nqaj hlau ntawm CNC tshuab cuab yeej qhia tau muab faib ua peb pawg hauv qab no, txhua tus muaj nws tus kheej cov txiaj ntsig zoo thiab tsim nyog scene:
I. Sliding Guideways: Ib qho Kev Xaiv Yooj Yim
Nta:
Cov qauv yooj yim: kev sib cuag ncaj qha ntawm qhov chaw ntawm cov kev taw qhia kev tsheb ciav hlau los tsim kev sib txhuam zawv zawg, tsis muaj cov txheej txheem dov lossis cov tshuab hydraulic, yog li cov nqi tsim khoom qis, tsim nyog rau kev siv nyiaj - txwv tsis pub siv.
Qhov tseem ceeb rigidity thiab kev vibration tsis kam: qhov saum npoo ntawm cov lus qhia kev tsheb ciav hlau muaj qhov chaw sib cuag loj, uas ua rau nws tuaj yeem tiv taus qhov loj txiav quab yuam thiab kev cuam tshuam, thiab nthuav tawm kev ruaj ntseg hauv cov cuab yeej siv tshuab hnyav lossis kev ua haujlwm ntxhib.
High Frictional Resistance: siab zoo li qub kev sib txhuam coefficient (feem ntau yog 0.1 -0.3), qis ceev yog ib qho yooj yim rau "squirm", uas ua rau cov neeg pluag positioning raug.
Kev hnav thiab tsim kua muag nrawm: kev hloov kho tsis tu ncua thiab lubrication ntxiv yog xav tau tom qab ua haujlwm ntev, ua rau qhov tsis zoo ntawm kev tuav pov hwm. Feem ntau yog siv rau cov khoom siv CNC yooj yim nrog cov kev xav tau tsawg precision.
Cov ntawv thov: tsawg ceev, tsis tshua muaj load daim ntaub ntawv xws li Economical CNC lathes thiab milling tshuab.
ii. Qhia Rail ntawm Rolling Mill: Mainstream Solutions rau Siab -Speed Servo Precision Processing
Nta:
Kev sib txhuam coefficient tsis tshua muaj siab: los ntawm kev siv cov khoom siv dov xws li lub pob, nruas lossis tus pin, zawv zawg kev sib txhuam yog hloov mus rau hauv kev sib txhuam, uas ua rau kev sib txhuam coefficient tsawg li 0.0025-0.005, ua rau lub zog du thiab hloov tau.
High Positioning Accuracy: qhov sib txawv ntawm dynamic kev sib txhuam coefficient thiab zoo li qub kev sib txhuam coefficients me me, kom ntseeg tau tias du thiab qis ceev txav tsis tau nkag. Repeatability tuaj yeem yog ± 0.001mm, txaus siab qhov yuav tsum tau ua ntawm precision machining.
Hnav tsis kam thiab lub neej ua haujlwm ntev: lub cev dov thiab qhov chaw ntawm cov kev taw qhia rail kev nyuaj siab yog sib npaug, hnav tus nqi tsuas yog 1/50-1/100 ntawm cov kev taw qhia rail, zoo heev lengthening txij nkawm cycles.
1. Cov kev vibration tsis muaj zog: dov cov ntsiab lus yog rhiab heev rau cov loads, yuav tsum muaj siab -rigidity txaj thiab vibration damping li, thiab yuav tsum tau muaj kev tiv thaiv siab (plua plav thiab nti tiv thaiv).
Subtype:
Daim ntawv qhia pob: taw tes rau kev tsim qauv, kev sib txhuam qis, kev kub ceev, haum rau lub teeb thauj khoom, qhov xwm txheej ceev (xws li siab -cov chaw machining ceev). Cov lus qhia rau cov menyuam yaus: xaim kev sib cuag tsim, 3-5 zaug muaj peev xwm nce, haum rau kev txiav hnyav (xws li cov tshuab loj gantry milling).
Needle roller guide rail: compact qauv, haum rau cov khoom siv me me ntawm cov lej txwv hauv qhov chaw.
Cov ntawv thov: High-cov chaw machining ceev, precision sib tsoo tshuab, tsib-axis CNC tshuab cuab yeej thiab lwm yam siab -precision, siab- daim ntawv thov ceev.
III. Hydrostatic cov lus qhia: cov kev daws teeb meem zoo tshaj plaws rau ultra- cov ntawv thov raug thiab hnyav
Nta:
Kev sib txhuam cov kua dej tsis tu ncua: Cov roj tsis tu ncua los ntawm cov txheej txheem hydraulic sab nraud mus rau saum npoo ntawm cov lus qhia kev tsheb ciav hlau, tsim cov yeeb yaj kiab tsis sib xws (thickness 0.01-0.03mm), cov kua dej ntshiab, kev sib txhuam coefficient tsawg li 0.0005.
High precision thiab rigidity: siab roj zaj duab xis bearing muaj peev xwm (100 MPa thiab siab dua), rigidity 3-5 lub sij hawm ntawm dov qhia rail, smooth txav tsis tau nkag, ruaj khov qhov tseeb nyob rau hauv ± 0.0005mm.
Kev co zoo heev thiab kev pab cuam lub neej: roj zaj duab xis absorbs txiav kev co, txo deg waviness, vim hais tias tsis muaj kev sib cuag ncaj qha ntawm kev taw qhia rail nto, theoretical kev pab cuam lub neej yog unlimited (tsuas yog roj zaj duab xis stability).
Compact thiab kim: Precision hydraulic systems (xws li lim, twj tso kua mis, thiab lwm yam) yuav tsum tau, nrog raug nqi 2-3 zaug ntawm dov qhia rails. Nws kuj tseem muaj cov kev cai nruj rau kev huv ntawm cov roj (NAS 6 lossis siab dua) thiab tswj qhov kub thiab txias.
Subtype:
Liquid static Liquid hydrostatic guide: mineral oil or synthetic oil as medium, haum rau ultra-precision machining (xws li, optical grinders, coordinate boring machine).
Gas static guide rail: Compressed air as a medium, tsis muaj kuab paug, tab sis tsis tshua muaj peev xwm nqa, feem ntau yog siv los ntxuav ib puag ncig (xws li, integrated circuit manufacturing khoom).
Cov ntawv thov: Ultra- precision machining chaw, hnyav- lub luag haujlwm CNC gantry milling tshuab, aerospace tivthaiv ua cov khoom siv thiab lwm yam siab - precision, hnyav load scene.
Cov kev xaiv: Cov peev nyiaj tsawg, cov kev xav tau tsawg tsawg: Ua ntej zawv zawg cov lus qhia rau kev sib npaug ntawm tus nqi thiab kev ua haujlwm yooj yim.
High-ceev, siab- precision machining: cov lus qhia rau cov menyuam yog thawj qhov kev xaiv, raws li kev thauj khoom tuaj yeem xaiv lub pob lossis cov menyuam hom.
Hydrostatic qhia yog tib txoj kev xaiv thiab yuav tsum muaj kev tshaj lij hydraulic system thiab pab pawg saib xyuas.
