Go with constant infeed,

so? What the hell is this, a blog?
stfu.

And if you feed at an angle across the work (as you suggested)
then your exit canbe (at best) at full wheel width of cut.
This means that you are either missing much of the stock
entirely or are cutting in triangular patches .. IOW at 50% ..
which is no better then indexing only on one end of the passes.

It's hotter, wears the wheel more, and takes longeer. But don't let any
of
those silly things stop ya.
lol

I wonder how much you know about grinding,
productive or otherwise.

Well, your way I guess you would pick up the first pass instantly, as
opposed to a gradual lead-in across that first pass.

"Question was about crossfeed."

Is this a blog?



However, grinding with a constant infeed will spread the wear out between
the face and the bottom front of the wheel,

How so? Have a pic of your intended geometry & application, including
vectors? Sounds like apples & grapefruit (or bricks).

Too technical for me.



allowing you to take BIGGER
infeeds and use faster long feeds and take deeper cuts to easily make up
that first leading pass and then some.

"face and the bottom front"?
"first leading pass"?

You should be in politics.
First leaning pass is the one that starts at one coraer and makes its way
to the other end of the table
at the full value of the crossfeed?
There, that sounded tekky.



Grinding this way will allow most flat grinding to be done on a finer
harder wheel, which will get even less wear, and the same finish for a
bigger stopovers.

That takes a lot more $$ time, right?
Perhaps you want to restate some of this?

Same finish for bigger stepovers....hmmm, sounds like a money maker?
even less wear...............................hmmmm, sounds like a money
maker?

One of us is very confused.



But like always depends on the application and available resources.

Well thank you for not pasting the whole "magazine" article.

First of all....I shouldn't have posted stfu. Those are universal fighting
words. I apologize.
As far as grinding goes however there are no rules. There is no best
"universal" way. If you have a grinder that can plunge a 2" wide wheel .300
deep in one pass ice cold, then by all means...plunge grind. If all you have
is coarse soft wheels, then by all means, infeed at each end of the stroke.
For the equipment that guy described, for general flat grinding I suggest
a constant infeed, and go up one grit and one hardness than you normally
use.

(dont paste links here, im too lazy to click and read magazine articles)
