TOOL MOVEMENT INDICATOR
(Gage system method of parts readout)
Multiply by ratio of tool movement to type dial indicator used to ac al stone displacement for type mandrel used. For
long run production, etc. extremely fine adjustments to ratios may be made by slightly adjusting bearings to provide the
desired reading. (not normally necessary).
EXAMPLE: Using a 0.001" Shop Dial Indicator
The ratio of approximately 10 to 1 would read directly to the stone for an R series mandrel (regular). Therefore a
dial indicator numbers (not graduations) can read directly. Do not forget to compensate for stone wear. Special Direct
Reading Indicator Sets are available.
Multiply by stone movement (in bore radius or diameter) to determine movement in bore diameter to obtain parts
readout less the stone wear. Adaptable to all commercial Honing units.
EXAMPLE: Using a .001" indicator read by standard (. 010) numbers on the dial multiply by the ratio. For 10 to 1
some conventional honing units will require twice this multiple. Some will require this 3 times and some will be the multiple
divided by 3. Multiplying by 10 gives a reading directly from the numbers on the dial. Next verify the tool movement of the
stone against the change of the actual diameter of the work to be honed. Determine the ratio desired for the type of
honing unit in the spindle chuck either an exact ratio or one that compensates for the estimated stone wear (especially
useful in production honing). If production job is long and stones are of the exact same composition; the honing dial can
be used to great advantage in keeping this ratio constant. Multiply ratio by indicating reading in hundredths of an inch.
Indicator must be set to read the movement of the Feed Screwdevice at the rear of machine. The Feed Screw has
an intricate pressure control system which will maintain feed pressure against the stone by the Feed Screw. Indicator may
be set to measure this movement normally by allowing only five thousandths (. 005) play or take-up travel on feed screw
which floats depending on lateral motion for spring tension or pressure to the stone.
