Galas Bebola Alur Dalam Miniatur
pengenalan
Galas bebola alur dalam mikro merujuk kepada siri metrik, diameter luar kurang daripada 9mm;Siri inci, diameter luar adalah kurang daripada 9.525mm semua jenis galas, bahan utama ialah keluli karbon, keluli galas, keluli tahan karat, plastik, seramik, dll, diameter dalam boleh sekecil 0.6mm, dalaman umum diameter 1mm lebih.
Ciri-ciri
Dalam apertur ultra kecil dalam galas kecil, jenis galas bebola dalam alur kecil mempunyai metrik 68 siri, 69 siri, 60 siri, dll, inci pada jumlah siri 6 R, berdasarkan ini, juga boleh dibahagikan dengan keluli ZZ siri galas penutup habuk, cincin pengedap getah dengan siri galas miniatur RS, siri pengedap galas teflon dan siri penal bebibir dan sebagainya.
Permohonan
Sesuai untuk semua jenis peralatan perindustrian, motor berputar kecil medan hingar rendah berkelajuan tinggi, seperti: peralatan pejabat, motor mikro, instrumen, ukiran laser, jam kecil, pemacu lembut, pemutar tekanan, gerudi pergigian, motor pemacu, motor melangkah, Drum magnet VCR, model mainan, kipas penyejuk komputer, kertas, mesin faks, dan sebagainya kawasan berkaitan.
Perhatian
1. Letakkan seterika kuk pada muka hujung enjin utama.
2. Masukkan palam ke dalam soket kuasa dengan suis kawalan.
3. Periksa sama ada wayar pembumian berada dalam keadaan baik, dan uji dengan pen pengukur selepas kuasa dihidupkan.
4. Tekan butang mula dan hos dihidupkan.
5. Periksa bahawa besi kuk tidak mempunyai voltan ke tanah.
6. Tekan butang berhenti untuk menghentikan pemanasan apabila mesin hos dimatikan.
7, Mengikut spesifikasi yang berbeza dari galas kecil atau bahan kerja lain, pilih penutup besi kuk yang berbeza, letakkan besi kuk di bahagian atas mesin utama, harus konsisten dengan licin.
8. Apabila memanaskan galas kecil, penderia hendaklah dimasukkan ke dalam "soket penderia" dan penderia hendaklah dilekatkan pada bahan kerja yang dipanaskan.
