Thaum lub chaw CNC machining los yog siab - nrawm ntau- axis theem poob qhov tseeb txawm tias txhim kho lub pob ntsia hlau ua ntej, cov kws ua haujlwm hauv teb feem ntau cem cov ntsia hlau pitch yuam kev lossis servo tuning tsis. Nyob rau hauv lub khw hauv pem teb, kev poob siab (rov qab) thiab tsav ntxov ntxov- kawg kev co yog feem ntau tshwm sim los ntawm kev xaiv cov kabmob tsis raug lossis tsis raug mountingPob Screw Support Units (BK/BF Series).
Cov kev txhawb nqa blocks ruaj ntseg ntsia hlau spindle rau lub tshuab ncej. Yog hais tias lub vaj tse flexes txawm me ntsis nyob rau hauv thrust, qhov micro-deflection hloov ncaj nraim mus rau hauv axial poob zog ntawm lub workpiece. Txhim khu kev ntseeg tau lub pob ntsia hlau tsav teeb tsa tau faib txoj haujlwm nruab nrab ntawm chav tsev ruaj khov (BK) thiab chav nyob ntab (BF). Lub thaiv ruaj ruaj tuav txhua qhov me me ntawm axial load los ntawm kev nrawm nrawm, nres, thiab ua haujlwm hnyav. Zoo BK blocks packs matched khub ntawm angular hu pob bearings (feem ntau nrog ib tug 30℃los yog 60℃kev sib cuag lub kaum sab xis) mounted nyob rau hauv ib tug rov qab - mus rau -rov qab (DB) kev npaj. Qhov kev teeb tsa no kaw qhov kawg ntawm axial-ua si, ua kom lub ntsej muag nruj tiv thaiv lub sijhawm qaij, thiab tswj kev txhawb nqa nruj. Ib tug precision locknut nrog tooj dag locking pins clamps cov kabmob puab rings nruj nreem tiv thaiv lub xub pwg nyom tsis ua rau cov ntsia hlau threads. Nyob rau ntawm qhov tsis yog -tsav kawg, lub floating unit (BF) tuav lub ncej radially thaum tso cai rau nws swb rov qab thiab tawm mus dawb.
Floating -kawg chav tsev (BF) yuav tsum tso cai rau axial txav dawb thaum txwv radial runout. Lub tsev BF muaj ib qhov tob -groove pob bearing tuav ntawm cov ntawv xov xwm ncej nrog lub nplhaib sab nraud. Raws li cov ntsia hlau spindle tig ntawm kev kub ceev, kev sib txhuam ua kom sov, ua rau cov ncej hlau nthuav dav ntawm kwv yees li 12 μm / (m·℃). Yog hais tias ob qho tib si ncej kawg yog axially xauv, thermal expansion tsim muaj zog compression loj nyob rau hauv lub spindle, ua rau lub hau hneev thiab yuam cov bearings overheat thiab spill. Tso cai rau cov ntawv xov xwm floating kom plam axially hauv BF vaj tse absorbs thermal kev loj hlob thiab tswj kev sib tw tsav torque.
Kev daws teeb meem Field Integration: FAQ rau Kev Muag Khoom & Pab Pawg Sib Koom Tes
Vim li cas lub axis nthuav tawm axial backlash txawm tias tom qab txhim kho lub preloaded, xoom-backlash pob txiv ntoo?
Axial txav feem ntau tshwm sim hauv qhov kev txhawb nqa ruaj khov es tsis yog pob txiv ntoo. Yog tias tus neeg muag khoom hloov tus qauv radial sib sib zog nqus-groove pob bearings rau kev sib tw angular contact bearings hauv BK unit, axial loads yuav hloov cov kabmob rings hauv lawv cov radial clearances. Backlash kuj tshwm sim yog hais tias qhov precision locknut nyob rau hauv - torqued los yog lub xub pwg nyom lub ntsej muag tsis perpendicular mus rau lub journal axis, tsim uneven bearing zaum.
Dab tsi yog cov txheej txheem kom raug rau kev sib koom ua ke BK / BF txhawb nqa thaum lub sijhawm sib dhos tshuab?
Mounting kev txhawb nqa tsis muaj qhov taw qhia kev sib dhos ua rau muaj kev sib khi hnyav thiab qaug zog tsis ua haujlwm ntawm cov ntawv xov xwm ntsia hlau. Ua ntej, ntsia liaj qhov rooj BK tsau rau lub hauv paus tshuab thiab ruaj ntseg lub pob ntsia hlau phau ntawv xov xwm nrog lub xauv. cheb lub dial taw qhia raws tus ntsia hlau xov av thaum manually txav lub carriage mus dlhos lub floating - kawg puag phaj. Tsuas yog zawm BF thaiv bolts tom qab ua kom cov ntsia hlau ntxaiv nyob twj ywm rau tib lub sijhawm rau cov kab ntawv qhia kab hauv 0.01mm hla tag nrho cov hlab ntsha ntev.
Cov engineers xaiv li cas ntawm thaiv -hom (BK/BF) thiab flange-hom (FK/FF) txhawb units?
Qhov kev xaiv nyob ntawm qhov mounting interface ntawm lub tshuab qauv. Base-mounted BK/BF blocks feature tiaj hauv qab nto nrog keyways los yog dowel pin qhov, tsim los zaum ncaj qha rau ntawm kab rov tav machined siv txaj. Flange-mounted FK/FF units feature puag ncig vaj tse flanges tsim los ntxig los ntawm boreholes nyob rau hauv ntsug bulkheads los yog lub cev muaj zog mounting vaj tse, ua rau lawv haum rau compact Z- axis theem los yog tubular tshuab thav ntawv.
Technical Performance Matrix
| Unit Configuration | Internal Bearing Spec | Axial Load Mechanism | Thermal Expansion Behavior | Application Interface |
| BK (Fixed Base Unit) | Matched Angular Contact Pair (30℃/ 60 degree, DB Teeb) | Bidirectional High Axial Thrust | Rigidly Constrained ntawm Drive End | Bolted rau lub tshuab pav ca txaj / rooj |
| BF (Floating Base Unit) | Tib Deep Groove Pob Bearing | Kev taw qhia Radial nkaus xwb | Dawb Axial Slip Sab Hauv Tsev | Tsis yog-Drive Shaft End Support |
| FK (Fixed Flange Unit) | Matched Angular Contact Pair (30℃/ 60 degree, DB Teeb) | Bidirectional High Axial Thrust | Rigidly Constrained ntawm Bulkhead | Muab tso rau hauv Perpendicular Housing Wall |
