Mukuchera maindasitiri epamusoro-soro uko kusarongeka kunoreva njodzi,HSS Taper Shank Twist Drillsinobuda seyekupedzisira mhinduro yekugadzira zvimiro, kugadzirisa, uye inorema kugadzirisa michina. Yakagadzirirwa kurovera simbi yakakandwa, alloys esimbi uye dense composite pasi pemaitiro akasimba ekushanda, aya maMorse taper shank drills anoshandura brute force kuita yekuvhiya chaiko.
Yakakura-Gomba Protocol: Iyo Yakatsikwa Kuchera Kubatsira
Kune makomba > Ø60mm, iyo 3-nhanho yekuchera inoteedzana inodzivirira kutadza kwechishandiso:
Pilot Precision: Ø3.2-4mm HSS bit inogadzira kushushikana-kudzoreredzwa pekutangira
Yepakati Danho: Ø12-20mm taper drill inowedzera gomba ne chip clearance
Final Bore: Yakazara-diameter taper shank bit inoshanda pa80-120 RPM
Mhedzisiro: 60% yakaderera torque inoda kuchera Ø80mm maburi musimbi yakakandwa vs. single-pass kuedza.
Toolholding Mirairo: Iyo Pfupi & Yakasimba Dzidziso
Shank Engagement: Morse taper sockets inofanira kunge isina ruvara-kusvibiswa kunokonzera 70% grip kurasikirwa.
Protrusion Control: Drill overhang ≤4xD kureba (semuenzaniso, Ø20mm bit max 80mm kuwedzera)
Kutadza Kudzivirira: Zvishandiso zvipfupi zvinoderedza chatter amplitude ne300% musimbi isina tsvina.
RPM Zvakazarurwa: Iyo 80-120 Sweet Spot
| Material | Yakakwana RPM | Torque (Nm) | Kudyisa (mm/rev) | Thermal Danger Zone |
|---|---|---|---|---|
| Cast Iron | 80-100 | 120-180 | 0.15-0.25 | >150 RPM (650°C) |
| Structural Steel | 90-110 | 150-220 | 0.10-0.20 | >130 RPM (720°C) |
| Aluminium Alloy | 100-120 | 80-130 | 0.25-0.40 | >180 RPM (550°C) |
Physical principle:
Yakaderera RPM = Yakakwira torque = Yakamanikidzwa chip kuumbwa (kucheka chiito)
High RPM = Fruction dominance = Kumucheto tembiricha inodarika HSS red-hardness (540°C)
Material Science Edge
Core Metallurgy: M2 high speed simbi
Thermal Defense: TiN coating inowedzera 150 ° C yekupisa buffer
Flute Geometry: 32 ° helix inogonesa chip kuyerera nekumhanya kwakaderera
Operator Survival Kit
Inotonhorera Mandate: Emulsified mafuta (8: 1 ratio) mafashama kutonhora
Chip Clearance: Kudzvanywa kwemhepo kuputika panguva yekudzosa peck
Kukundikana Zviratidzo:
Blue shank = Over-RPM
Snapped tip = Chip clogging
Oval makomba = Mutyairi asina kukwana
Mhedziso
HSSTaper Shank Drillskubudirira uko high-torque chaiyo inosangana nekuraira kwekushanda. Nekugona - 90 ° kurongeka, kudhirowa nhanho, kushoma overhang, uye 80-120 RPM - inogara yakasimba, inoita zvirinani, uye inodhura kupfuura vamwe mukirasi yavo.
