Qhov tseeb ntawm gantry machining center yog ib qho tseem ceeb ntawm kev ua tau zoo, cuam tshuam ncaj qha rau qhov loj, zoo, thiab qhov tseeb ntawm qhov chaw machined. Los ntawm kev pom kev, qhov tseeb yog feem ntau txiav txim siab los ntawm lub tshuab cuab yeej tsim qauv, tsav lub cev (xws li lub pob ntsia hlau thiab cov kab ntawv qhia), spindle kev ua tau zoo, thiab kev tswj lub peev xwm ntawm CNC system. High -precision gantry machining centres feem ntau ntiav kaw- voj lossis ib nrab- kaw- lub voj voog tswj, siv qhov ntsuas lossis ntsuas ntsuas los muab qhov tseeb- lub sij hawm txoj hauj lwm tawm tswv yim, xyuas kom meej qhov chaw yuam kev nyob rau hauv ± 0.005mm thiab repeatability mus txog 003mm. Cov yam ntxwv cuam tshuam rau qhov tseeb tuaj yeem muab faib ua cov tshuab, hluav taws xob, thiab ib puag ncig. Mechanically, guideway straightness thiab spindle radial runout (feem ntau Tsawg dua los yog sib npaug rau 0.002mm) thiab axial play (Less dua los yog sib npaug rau 0.001mm) yog qhov tseem ceeb. Hluav taws xob, lub servo tsav cov lus teb ceev thiab CNC system interpolation algorithm ncaj qha cuam tshuam qhov tseeb qhov tseeb. Ib puag ncig, kub hloov pauv (pom zoo hauv ± 2 degree), av noo (40% -60%), thiab kev co hauv pem teb (tsawg dua lossis sib npaug li 5μm) yuav tsum tau tswj nruj me ntsis. Cov txheej txheem kev lag luam hais tias txoj kab sib koom ua ke qhov tseeb ntawm qhov siab -kawg gantry machining chaw yuav tsum ua raws li ISO 230-2 thiab VDI/DGQ 3441. Piv txwv li, rau lub tshuab nrog thaj tsam machining ntawm 1400 × 1350mm, X / Y / Z txoj hauj lwm yog sib npaug ntawm Lcuracy. 0.01mm / m, thiab rov ua dua Tsawg dua lossis sib npaug li 0.005mm / m. Hauv kev siv aerospace, aerospace qhov chaw (xws li cov hniav thiab cov casings) yuav tsum tau micron - qib raug, thaum cov pwm ua qhov tseem ceeb dua ntawm qhov roughness (Ra Tsawg dua lossis sib npaug li 0.8μm) thiab qhov tseeb contour. Kev ntsuas txhawm rau txhim kho qhov tseeb suav nrog kev ntsuas qhov ntsuas tsis tu ncua (pom zoo txhua rau lub hlis), kev siv cov khoom siv high-precision (xws li xoom-point positioning systems), optimized txiav tsis (xws li spindle speeds ntawm 8000-12000rpm thiab pub tus nqi ntawm 1000-3000mm / min), thiab kub deformation.
