The Gomba Rakadzika Boring Tube ndicho chepakati chikamu cheBTA (Boring uye Trepanning Association) yakadzika gomba yekuchera masisitimu. Yakagadzirirwa kugadzirwa kwepamusoro-soro kwemakomba akadzika ane kudzika-kusvika-dhayamita reshiyo (D: d) ≥ 10: 1, inoshandiswa zvakanyanya muaerospace, simba, uye maindasitiri emotokari. Inoenderana neese Single Tube (STS) uye Double Tube (DTS/Ejector) masisitimu, ichishandisa yakakwirira-kudzvanya inotonhorera uye yakasimba dhizaini kuti ive nechokwadi chakagadzikana chip evacuation.
Core Positioning & Working Principle
- Essence: Chimiro chetubular chinoshanda nehunyanzvi kudhiraivha / kufinha misoro kufambisa simba rekucheka, kuendesa yakakwira-kutonhora inotonhorera, uye kubudisa machipisi.
- Single Tube (STS/BTA): Inotonhorera inopinda munzvimbo yekucheka kuburikidza neannulus pakati pechubhu OD uye rusvingo rwegomba; machipisi anoburitswa nepaburi remukati rechubhu. Inoda workpiece chisimbiso uye kumanikidza musoro. Yakanakira gomba madhayamita 12–850 mm uye kudzika reshiyo ≥ 100:1. Kunyatsoita 3-5 nguva iyo yekuchera pfuti.
- Kaviri Tube (DTS/Ejector): Inotonhodza inoyerera nepakati pemachubhu emukati nekunze; machipisi anoburitswa nemuchubhu yemukati. Hapana musoro wekumanikidza unodiwa, uchiita kuti uchinje kune akajairwa muchina maturusi. Yakakurudzirwa max kudzika ndeye 1000 mm (kusvika 2000 mm ane maadapter anokosha), akakodzera gomba madhayamita 18-250 mm.

| Tube Straightness | ≤ 0.02 mm/m | ≤ 0.03 mm/m | Yakakosha kune gomba kutwasuka uye cylindricity |
| Kukasharara Kwepamusoro | ID Ra ≤ 1.6 μm | ID Ra ≤ 3.2 μm | Inoderedza njodzi yekuvhara chip |
| Connection Akarurama | Thread Runout ≤ 0.01 mm | Zvakafanana neKuruboshwe | Inovimbisa concentricity uye dynamic balance |
Mamiriro ekushandisa & Sarudzo Yekutungamira
- Zvishandiso Zvakakodzera: Carbon simbi, alloy simbi, Stainless simbi, titanium alloy, yakakwirira-tembiricha alloys. Kunyanya kushanda kune zvinhu zvinogadzira machipisi akareba, ane tambo.
- Mamiriro ekusarudza:
- Diameter/Kudzika: Pamakomba <18 mm, koshesa Single Tube. Pakudzika> 1000 mm, koshesa Single Tube + Pressure Head.
- Mhando yemuchina: Shandisa Double Tube kune akajairwa lathes/vertical machining centers; shandisa Single Tube kumichina yakatsaurirwa gomba rakadzika.
- Kubudirira: Single Tube inopa hunyanzvi hwepamusoro; Double Tube inopa kuchinjika kukuru.
Zvakanakira & Operational Notes
- Core Advantages: Yakakwira kudzika-kusvika-dhayamita reshiyo kugona, yakakwira machining chaiyo (Hole Tolerance IT7-IT9, Surface Ra ≤ 1.6 μm), yakatsetseka chip evacuation, uye yakafara zvinhu kuchinjika.
- Operational Notes:
- Inotonhorera kusefa kurongeka kunofanirwa kuve ≤ 10 μm kudzivirira kuvhara.
- Gomba rekutyaira rinodiwa (Diameter = Boring Tube ID - 0.5 mm, Kureba ≥ 2x gomba dhayamita).
- Kudzora kutema parameters: Speed v = 30-100 m / min, Feed f = 0.1-0.3 mm / rev (gadzirisa zvichienderana nezvinhu).
