Indlela Ama-HSK Tool Holders Akhulisa Ngayo Ukunemba Kwezimboni

Ukuphambuka konakalisa impilo yethuluzi. Ekugilingeni ngesivinini esiphezulu, i-radial runout engu-0.005 mm kuphela inganciphisa impilo ye-end mill nge-15% kuya ku-20%. Imishini yesimanje yokucubungula yezimboni idinga ukuxhumana okuqinile phakathi kwe-spindle nethuluzi okungagobi ngaphansi kwemithwalo ephezulu ye-centrifugal. Amadizayini e-Hollow shank taper (HSK) axazulula le nkinga yomshini ngokuxhumana kanyekanye kobuso kanye ne-1:10 taper.

Lapho ama-taper ajwayelekile agqamayo ehluleka kuma-RPM aphakeme, izixhumanisi ze-HSK zikhiya ngokuqinile njengoba isivinini sikhuphuka. Umphumela uwukuphela kwendawo okungalindeleka, ukuphindaphinda kwezinga le-micron, kanye nokonga izindleko okumangalisayo kuyo yonke imigqa yokukhiqiza enzima.

Isilinganiso Semakethe Yamathuluzi Anembile kanye Neqiniso Le-Runout

Ukutshalwa kwezimali ezinkulu ekucubunguleni okunembile kuyaqhubeka nokukhula njengoba ukubekezelelana kwezingxenye kuqina kuyo yonke imikhakha yezindiza, izimoto, kanye nokukhiqiza kwezempilo.

Imakethe yomhlaba wonke yemishini ye-CNC yafinyelela ku-$88.3 billion ngo-2023, ngokusho kwe-Gardner Intelligence's 2024 World Machine Tool Survey, kanti amasistimu e-5-axis asheshayo ahamba phambili ku-38% wokufakwa kwezimboni ezintsha.
Ucwaningo olushicilelwe ku-CIRP Annals (2022, Vol. 71) lwabonisa ukuthi ukugoba kwe-spindle interface kufinyelela ku-32% wesikhathi samaphutha okusebenza ngesikhathi sokusebenza ngamandla kwe-aluminium roughing.
I-VDMA Machine Tools and Manufacturing Systems Association yabika encwadini yayo yokuhlola umnotho ka-2024 ukuthi ukusethwa kwamathuluzi okuzenzakalelayo kwehlise isikhathi sokuphazamiseka kwe-spindle okungahleliwe ngo-19.4% kuzo zonke izindawo zokukhiqiza zaseYurophu.

Yebo, lelo gebe libaluleke kakhulu kunalokho ongakucabanga. I-runout ayiyona nje into embi ebusweni obugayiwe; iyisandisi-mali esikhula ngokwezinga eliphindaphindayo.

Umkhawulo we-Radial Runout ongu-0.003 mm

I-runout yethuluzi ikala ukuphambuka kwe-eksisi ejikelezayo yesisiki kusuka kumugqa waphakathi we-spindle wethiyori. Kukalwa ku-3× ububanzi bethuluzi (3D), izibambi ze-steep-taper ezijwayelekile zivame ukukhombisa u-0.008 mm kuya ku-0.012 mm we-total indicated runout (TIR).

Ngokuphambene, amasistimu e-HSK anemba agcina i-TIR ngaphansi kuka-0.003 mm. Lapho umphetho ngamunye wokusika uhlangana nento esetshenzwayo ngemithwalo efanayo yama-chip, ukuguga kwe-flank kukhula ngokulingana. Lokho kulingana kuvimbela ukuqhekeka kwangaphambi kwesikhathi kanye nokuqhekeka okuncane kumathuluzi e-solid carbide.

I-Spindle Speed Dynamics Engaphezulu kuka-15,000 RPM

Ezingeni lokujikeleza elidlula i-15,000 RPM, amandla e-centrifugal andisa imbobo yebheringi yangaphambili yesipindle somshini. Kuma-taper aqondile e-BT noma e-CAT endabuko, lokhu kwandiswa kwembobo kudonsela isibambi sijule ngakuyi-Z-axis (umphumela owaziwa ngokuthi i-Z-axis pull-in).

Izibambi ze-HSK zilwa nalokhu kwandiswa ngeminwe yokubamba yangaphakathi eyizingxenye. Ngenxa yokuthi udonga lwe-shank luyize futhi luncane, amandla e-centrifugal andisa kokubili imbobo yesipindle kanye ne-shank yethuluzi ngesikhathi esisodwa. Ingcindezi yokuthintana empeleni iyakhula njengoba isipindle sishesha.

Izilinganiso Zekhwalithi Ephezulu Zomshini Wokucubungula Wezimboni
