    Onze bestelling voor meerdere PLC-eenheden en HMIs is accuraat uitgevoerd en met verbazingwekkende snelheid verzonden. Sinds de integratie ervan is de communicatie van ons besturingssysteem robuuster. We zijn onder de indruk van de logistiek en de solide prestaties van deze componenten. Een probleemloze ervaring in alle opzichten.

    We hadden een stille spindelmotor nodig voor een gevoelige testomgeving. De unit die we kochten werkt fluisterstil en behoudt een constante draaimoment. De kwaliteit overtreft die van sommige bekende merken die we hebben gebruikt, voor een fractie van de prijs. Uitzonderlijk voor gespecialiseerde toepassingen.
