Yes, I use a center cutting endmill. Yes the tool is sharpened properly. And yes, I am going t change the brand of endmill this week to Guhring, a good german brand.
Since the work piece rotates on the 4th axis and the endmill rotates in the z axis and the piont of contact between the endmill and the workpiece is a curved mass of metal(rotating), the resultant is probably producing this anomaly?
Will try out all your suggestions and give feedback.
