Place blocks at each end of the chuck, and using hold down clamps

positions of the cross feed selector lever.

Table Traverse Speed Setting

Table traverse speeds are set by controls #11 and #12. Control
#11 establishes the table traverse speed for grinding. This speed is
adjustable up to 125 feet per minute.

Control #12 establishes a lower range of table speeds, suitable

for table positioning during setting up. These speeds are also adjustable.

Lever #13 extending from the side of control #12 is used to

select the fast (grinding) or slow speed range after initial settings have been
made.

a diamond holder can be held

> the diamond holder can be

clamped to the table surface by means of a bolt in the tee slot of the

table.

It is good grinding practice to locate the diamond holder on the
left portion of the spindle. Then lower the grinding wheel until it touches
the diamond lightly. Cross-feed the saddle (with lever #7 in "Truing"
position) until the diamond passes beyond the edge of the wheel and then

feed down about 0. 0005" and feed the diamond back across the wheel
until it clears the opposite edge.

Repeat this procedure with

appropriate

downfeeding until, by the sound of the wheel in contact with the diamond,
it is certain that the entire face of the wheel has been dressed to the

condition required.

If a roughing operation is to be performed,

use a compara-

tively fast traverse of the diamond across the wheel face. A fine finish
requires a slower traverse.

For a finer finish, move the diamond slowly
across the wheel face without any downfeed of the wheel during the last
several passes.

Setting Table Dogs

Set the table dogs for a given table speed so that the table will
reverse a minimum distance of approximately l" beyond each end of the
work.

Cross Positioning Work to Wheel

When it is desired to bring work into position with the wheel

by cross-feed of the saddle (assuming the hydraulic

pump is running and

the table is stopped), proceed as follows:

Set cross-feed selector lever #7 in the "PICK position.

There should be no movement of the saddle because the

When the grinding wheel has worn to the point indicated by
the line on the wheel guard instruction plate which reads 11 Change Wheel

. Remove cover on back of the wheel head column, and

locate the jack-bar held in the 11 up

. Lower the wheel head until the jack-bar bottoms and

When used without table traverse (primarily in "TRUE" or

"RAPID" cross feed), the automatic cross traverse reversal does not

function. It stops the saddle, allowing time to downfeed the wheel for

truing, or for engaging the cross feed hand wheel for final positioning.

Placing the control lever in the opposite position causes cross traverse

to resume.
