Hi,
We are honing some aluminum cylinders on our MBB-1660 Sunnen honing machine. Following the instructions from the manual we are getting some bellmouthing in the order of 5-10 microns on either end of the part. Have spent a fair bit of time trouble shooting but the problem persists.
At this point we will use the truing sleeve/true the stones, then run about five parts at 5 micron bellmouth. As we get to 15 or 20 parts the bellmouth gets to be about 10 microns at either end which we cannot accept.
I've heard that using this machine properly will yield nearly perfect bores. Would love to hear advice from those experienced honers out there!
Not sure if this is important but we are achieving .3 micron surface finish which is our target.
thanks,
Joey
