The vibration is when the carriage hits the left side to return back to the right is the way I am understanding your concerns. There is a small amount in those units when they switch direction, try slowing down the travel speed so it doesnt hit so hard. The first thing I would do is use a machinist level, maybe two and level the unit so it completely solid on the floor. Not your regular carpenters level, a good machinist level. That unit will do 6500 knives and it shouldn't take more than 10 to 15 minutes to do a touch up grind. You may also want to look at a CBN wheel for that unit, but to takes hours for a used knife for a 6500 tells me the stone must be loading up. The CBN will not require dressing and works great for worn knives, can grind harder, and last longer. Best part is there is a lot less movement of the carriage in and out because the stone does not wear like your typical rock wheel. Also you can call Foley, it's been awhile for me but I think there is an adjustment in the control box that can be made to regulated how hard it hits. You might be able to find it in your manuals as well. Major key is, being solid on all fours and perfectly level, and you can only get there through a machinist level. Some may not agree with it, but I learnd it the hard way and from one of the best in the business, Jim Soullier. I use them for my lathe, Mill, and all my reel grinding equipment. If you want it to run right, it has to be setup right. Not saying yours isn't, but thats the starting point for it all.
