1. Esiperimenta Design
●Ohun elo:Awọn ọpa Ti-6Al-4V (Ø50mm)
●Ohun elo:5-axis CNC pẹlu itutu-ọpa (ibiti titẹ: 20-100 bar)
●Awọn Metiriki Tọpinpin:
Dada roughness (Ra) nipasẹ olubasọrọ profilometer
Ọpa flank wọ nipa lilo USB maikirosikopu aworan
Gige iwọn otutu agbegbe (kamẹra gbona FLIR)
2. Awọn iṣakoso atunwi
● Awọn atunwi idanwo mẹta fun eto paramita
● Awọn ifibọ irinṣẹ rọpo lẹhin idanwo kọọkan
● Iwọn otutu ibaramu ni idaduro ni 22 ° C ± 1 ° C
Esi & Onínọmbà
1. Coolant Ipa vs dada Pari
●Titẹ (ọpa):20 50 80
●Apapọ Ra (μm) :3.2 2.1 1.4
●Aṣọ Irinṣẹ (mm):0.28 0.19 0.12
Itutu agbara-giga (ọpa 80) dinku Ra nipasẹ 56% dipo ipilẹṣẹ (ọpa 20).
2. Nozzle Positioning Ipa
Awọn nozzles angled (15° si imọran ọpa) ṣaṣeyọri awọn iṣeto radial nipasẹ:
● Dinku ikojọpọ ooru nipasẹ 27% (data igbona)
● Gbigbe igbesi aye ọpa nipasẹ 30% (awọn wiwọn aṣọ)

1. Key Mechanisms
●Sisilo Chip:Ga-titẹ coolant fi opin si gun awọn eerun, idilọwọ awọn tun-Ige.
●Iṣakoso Ooru:Itutu agbaiye agbegbe dinku iparun iṣẹ-ṣiṣe.
2. Awọn idiwọn to wulo
● Nilo awọn iṣeto CNC ti a ṣe atunṣe (agbara fifa igi 50 ti o kere ju)
● Ko ṣe iye owo-doko fun iṣelọpọ iwọn kekere
Ipari
Ṣiṣapeye titẹ coolant ati titete nozzle ni pataki ilọsiwaju ipari dada titanium. Awọn olupilẹṣẹ yẹ ki o ṣe pataki:
● Igbegasoke si ≥80 bar coolant awọn ọna šiše
● Ṣiṣe awọn idanwo ipo nozzle fun ohun elo irinṣẹ pato
Iwadi siwaju sii yẹ ki o ṣawari itutu agbaiye arabara (fun apẹẹrẹ, cryogenic + MQL) fun awọn ohun elo ti o nira-si-ẹrọ.
