Kev tsim cov txheej txheem ntawm Surface grinders
I. Cov qauv tsim thiab xaiv cov khoom siv
Main Structural Layout
Cov txheej txheem ntxaiv (kab rov tav lossis ntsug) yog txiav txim siab los ntawm txoj kev sib tsoo (peripheral lossis ntsej muag sib tsoo); Ua ke qhov no nrog lub rooj zoo (lub voj voog lossis voj voog) ua rau plaub qhov kev teeb tsa lub tshuab tseem ceeb.
Lub tshuab txaj feem ntau siv siab -rigidity cam khwb cia hlau lossis hlau alloy, raug rau kev laus kev kho mob kom txo tau cov kev ntxhov siab sab hauv thiab xyuas kom ntev - lub sij hawm stability.
Key Component Design
Spindle System: Ua haujlwm hydrostatic bearings lossis siab -precision dov bearings; muaj peev xwm mus txog ntau txhiab RPM nrog radial runout tswj ntawm micron theem.
Kev taw qhia System: Siv cov kev taw qhia cov menyuam precision lossis hydrostatic guideways, ua ke nrog tes -scraping cov txheej txheem los xyuas kom meej cov lus tsa suab.
II. Kev tsim cov txheej txheem rau cov khoom tseem ceeb
Spindle Machining
Cov ntaub ntawv xov xwm yog siv los siv ultra- precision grinders thiab txhim kho kev hnav tsis kam ntawm siab - zaus quenching lossis nitriding, ua raws li kev ntsuas qhov ntsuas.
Worktable Manufacturing
Rectangular tables yuav tsum flatness nyob rau hauv 0.005 mm / m, thaum lub rooj voj voog yuav tsum tau axial runout nyob rau hauv 0.003 mm; hybrid txheej txheem ntawm kev sib tsoo thiab tes-scraping yog ua haujlwm.
Sib tsoo Log System Integration
Lub taub hau lub log sib xyaw ua ke tsis siv neeg ntsuas qhov ntsuas thiab siv cov pob zeb diamond rau cov menyuam hnav khaub ncaws lossis CNC hnav khaub ncaws tshuab kom ua tiav kev hnav khaub ncaws zoo ntawm kev sib tsoo log.
III. Kev Sibtham thiab Kev Ua Haujlwm Kev Ua Haujlwm
Precision Assembly
Spindle-rau-table perpendicularity thiab parallelism yog calibrated siv laser interferometers, nrog kev ua yuam kev tswj kom tsawg dua los yog sib npaug li 0.005 mm.
Sib nqus chuck los ua ke yuav tsum sib nqus ncej sib nqus kom ntseeg tau tias tuav lub zog zoo ib yam thiab tiv thaiv kev txav ntawm qhov chaw ua haujlwm.
Dynamic Commissioning
Kev taw qhia rigidity yog kuaj nyob rau hauv simulated machining loads, thiab servo system tsis yog optimized rau suppress kev co.
IV. Txheej txheem Optimization thiab tshuaj xyuas
Tshwj xeeb Machining Techniques
Ultra{0}}ntev workpieces undergo segmented sib tsoo, nrog thermal deformation tswj los ntawm lub coolant ncig system.
Rau kev ua cov kauj ruam me me lossis chamfers, nplua -grit sib tsoo log (120K–360K) yog siv los ntxuav cov ces kaum hauv cov kauj ruam txuas ntxiv.
Kev tshuaj xyuas thiab calibration
Qhov loj me tseem ceeb raug tshuaj xyuas los ntawm kev siv lub tshuab ntsuas kev sib koom tes (CMM), thiab qhov roughness ntawm qhov chaw raug txheeb xyuas los ntawm ib qho dawb -light interferometer (Ra Tsawg dua lossis sib npaug li 0.1 μm).
V. Piv txwv ntawm Cov Txheej Txheem Txheej Txheem
Tshuab txaj casting → Kev laus kho → Rough milling → Precision sib tsoo ntawm txoj kev → Tes scraping;
Spindle forging → Rough tig → Thaum tshav kub kub kho → Precision sib tsoo → Dynamic ntsuas;
Worktable machining → nto sib tsoo → Sib nqus ncej sib dhos → Tuav lub zog kuaj;
Kev sib dhos tshuab → Laser calibration → Dynamic test → process verification.
