Meccanodora will be showing at EM0 a bearing track grindingmachine concept, which also allows for future developments inhard turning and mill-turning. The Futura turns the workpieceupside-down for the combined machining of the spherical innerdiameter and six ball tracks of an automotive constant velocityjoint outer race. In doing sop, it offers the followingadvantages: * The machine grinds the outer/inner diameters andtracks in one clamping, so improves final quality.

* Theslide-mounted workhead picks up and deposits workpieces from andonto a conveyor.

* The workpiece is automatically indexed forball tracks machining.

* The workpiece is continuously rotatedfor the machining of the spherical inner diameter.

* Machineslides are completely isolated from the working area, so thatguideways, motors, lubrication, hydraulic and pneumatic unitsnever come into contact with chips or coolant.

The machine isdesigned to operate with: * superabrasives or CBN wheels; *toolholders suitable for hard-turning using CBN tooling and *high frequency spindles for hard-milling using CBN tooling.
