Ce este finisarea in oglinda?
Finisarea in oglinda (mirror finishing) este procesul de obtinere a suprafetelor cu rugozitate extrem de scazuta, cu caracter reflectorizant, prin prelucrare CNC de precizie ultra-inalta. Noua tehnologie Hartford permite obtinerea acestor suprafete direct pe centrul CNC, eliminand operatiile de post-procesare manuala.
De ce conteaza finisarea de suprafata
- Rezistenta la coroziune: suprafetele mai netede reduc suprafata de atac a agentilor corozivi
- Durabilitate: finisajele fine reduc concentratorii de tensiune si oboseala materialului
- Performanta optica: esential pentru instrumente optice si sisteme laser
- Igiena: suprafetele netede sunt mai usor de curatat si sterilizat in echipamente medicale

Sistemul MGPS
MGPS (Micro-Level Precision Machining System) controleaza parametrii de prelucrare la nivel de micrometru, compensand vibratiile, variatiile termice si uzura sculei pe durata sesiunilor de pana la 64 de ore.
Aplicatii industriale
- Instrumente optice: lentile, oglinzi, prisme, componente laser
- Automotive si aerospational: componente de estetica si protectie anticorecie
- Echipamente medicale: suprafete igienice pentru implanturi si instrumente chirurgicale
- Matriterie: suprafetele matritelor de injectie cu cerinte estetice
What Is Mirror Finishing?
Mirror finishing is the process of obtaining surfaces with extremely low roughness and a reflective character through ultra-high-precision CNC machining. Hartford's new technology allows obtaining these surfaces directly on the CNC center, eliminating manual post-processing operations.
Why Surface Finish Matters
- Corrosion resistance: smoother surfaces reduce the attack surface for corrosive agents
- Durability: fine finishes reduce stress concentrators and material fatigue
- Optical performance: essential for optical instruments and laser systems
- Hygiene: smooth surfaces are easier to clean and sterilize in medical equipment
