We send all of our honing out to a outside vendor, considering purchasing a new Sunnen MBB1660 basic honing machine, mostly to help with cycle time on jobs. all job shop work tightest tol's are +0/-.0005. Finishes in the RA32-RA16 range. Materials mostly nitralloy 135, carbon steel,cast iron and occasional bronze and stainless. Typical job shop work, quantites from 1-10 pcs mostly. Mostly Bushings & clevis thru holes .50 dia - 3.0" dia, lg usually around 1"-6" max. What would be the cons to this particular machine for this type of work, seems to be the only size sunnen offers in the budget and tooling will be purchased on a job by job basis
