A rotary atomiser bell cup comprising a bell portion for spraying media in use and a hub portion via which the bell portion is rotatingly drivable in use, wherein the hub portion is a machined metal portion and the bell portion has been built up on the hub using an additive manufacturing process.
A method of manufacturing a rotary atomiser bell cup comprising a bell portion for spraying media in use and a hub portion via which the bell portion is rotatingly drivable in use, the method comprising the steps of:
- making the hub portion using machining;
- and
- building up the bell portion on the hub using an additive manufacturing process.
A method of manufacturing a rotary atomiser spindle including a bell cup comprising a bell portion for spraying media in use and a hub portion via which the bell portion is rotatingly drivable by the spindle in use, the method comprising the steps of:
- making the hub portion using machining, the hub portion having an interface portion for mounting to the spindle which interface portion comprises a datum;
- building up the bell portion on the hub using an additive manufacturing process;
- machining the bell cup relative to the datum after the additive manufacturing process;
- and mounting the bell cup to the remainder of the spindle for rotational drive.
