Re: [CAD_CAM_EDM_DRO] Bar stock

Happy Christmas, thanks very much for the replies, I understand what you
mean now. Does this mean rough turned stock would be more accurate? Are the
grinder wheels on centreless grinders continually adjustable? If I was to
grind huge loads of stock quite heavily the wheels would wear away and the
stock wouldn't be very accurate so do they move in as they wear away?
