Cov txuj ci

1. Profile Roughing: Tshem tawm cov khoom raws lub workpiece profile.
2. Pocket Roughing: Siv los tsim cov kab noj hniav lossis cov hnab ris hauv cov khoom ua haujlwm.
3. Lub ntsej muag Milling: Tshem tawm cov khoom ntawm qhov chaw tiaj tus.
4. Adaptive Clearing: Cov cuab yeej cuab tam niaj hnub no txhim kho cov khoom tshem tawm thaum txo cov cuab yeej hnav.

CNC Finishing yog dab tsi?

Txhais

CNC xov yog qhov xaus ntawm cov txheej txheem machining, qhov twg lub workpiece yog fine-tuned kom tau raws li qhov ntev ntawm qhov tolerances thiab ua tiav qhov yuav tsum tau ua tiav zoo.

Lub hom phiaj

1. Dimensional raug: Xyuas kom meej tias qhov kawg qhov ntev ua raws li cov kev kam rau ua.
2. Nto Zoo: Ua tiav du, aesthetically txaus siab, thiab functional nto finishes.
3. Yam tsawg kawg nkaus tshem tawm: Tshem tawm tsuas yog cov khoom seem uas tshuav tom qab roughing.

Yam ntxwv

• Siab Precision: Cov cuab yeej thiab cov txheej txheem tsom rau qhov tseeb thiab qhov tseeb ntawm qhov chaw.
• Slower Cutting Parameters: Tsawg tus nqi noj, ntiav txiav, thiab cov cuab yeej finer yog siv.
• Saib Kom Paub meej: Xws li kev ua haujlwm me me los kho cov yam ntxwv thiab cov npoo.

Cov txuj ci

1. Contour tiav: Rau qhov tseeb profileing ntawm ntug thiab contours.
2. Ua tiav Pass Milling: Ua tiav du, tiaj tus.
3. Chamfering thiab Deburring: Ntxiv cov ntsiab lus zoo rau cov npoo thaum tshem cov burrs ntse.
4. Polishing thiab Buffing: Txhim kho nto aesthetics ntxiv, yog xav tau.

Qhov sib txawv tseem ceeb ntawm CNC Roughing thiab Finishing

Kev siv ntawm CNC Roughing thiab Finishing

CNC Roughing Applications

1. Prototyping: Tsim cov duab ntxhib nrawm los ntsuas cov tswv yim tsim.
2. Loj Qhov Chaw Tsim Khoom: Ua tau zoo shaping loj workpieces nyob rau hauv aerospace los yog automotive industries.
3. Tuag thiab Pwm Ua: Npaj cov txheej txheem ntxhib ntawm cov pwm los yog tuag.
