How to True up the table/box? | Page 2 | The Hobby-Machinist
MadModifier - Latinrascalrg1's approach might be the easiest if the table is out consistently in all positions. I would allow use, further testing, and make some of the setups easier. A very interesting problem. Based on the geometry of the machine, it looks like either or both of the up/down or cross ways could be worn enough to allow some "sag".

GRINDING FEEDS AND SPEEDS
The wheel speed, in terms of peripheral speed, is commonly in the range of 5,500 to 6,500 fpm (about 30 to 35 m/sec). High-speed grinding, operating at about twice that speed, is used on specially built surface grinding machines only, which are designed generally for abrasive machining and require appropriately manufactured grinding wheels.
