2. Occasionally the cutting pressure used in the truing operation may not be right for honing the parts. It may be
necessary to reset the cutting pressure, depending on the part (material, length of part, roughness of hole, etc.). The
pressure should be just enough to produce good cutting action.
Note: Too heavy pressure can cause excessive stone wear; too light a pressure occasionally may result in stone
glazing instead of cutting. The cutting pressure control should not be moved more than a very slight amount at a time until
the most efficient pressure is established.
3. Turn motor ON and direct the oil stream on the honing unit so that the flow of oil will enter the hole being honed.
Depress foot pedal slowly until lever arm hits stop screw. At the same time proceed to stroke the part forward and back on
the honing unit. Be sure to overstroke each end of stone by 1/4 to 1/2 the hole length. Reverse the part on the honing unit
frequently and be sure that spindle is stopped before putting work on or taking it off the stone. Hone for feel and continue
to gage the hole size. Advance feed dial for amount of stock to be removed, hone in and gage. Repeat if necessary until
desired hole size is reached.
4. Hone each part (if several identical parts are to be honed), working for a feel and a timing. This will in a short
time become very easy. Diameter will, of course, be undersize by amount that stone wears. Therefore, advance feed
knob as necessary to compensate for the stone wear.
5. With a little practice you will soon be able to estimate very easily and accurately how much stone feed-up is
needed.
