GENERAL
The ANR-275 Hone has been designed to hone bores
from 2.50 to 21.00 in. (64 - 533 mm) diameter.
NOTE:
For light work in bores larger than 10 in.
(254 mm) in diameter.
INSTALLATION
The Remote-Feed Hones are designed for use in a
rigid installation, such as a drill press or a honing
rig, where part to be honed and power source are
rigidly fixed
(see Figure 1)
. The ANR-275 is
equipped with two Universal Joints which allow
the honing head to align itself with the workpiece.
POWER SOURCE
Use heavy duty electric drill in a honing rig, or drill
press
(see Figure 1)
. To establish optimum rpm for
your application, divide 800 by the hole diameter in
inches.
Example: 800 + 4" = 200 (rpm); or divide 20,000
by the hole diameter in Millimeters.
Example: 20,000 + 100mm = 200 (rpm).

HONING OIL
Use a continuous and ample flow of Sunnen
Industrial Honing Oil to ensure accurate, fast honing
and freedom from galling or scratches. Do not
dilute the oil. Do not use lubricating oil, cutting oil,
or water soluble oil; consistent results cannot be
expected unless the full-strength recommended oil
is used.
ASSEMBLY OF STONES AND GUIDES
1. Pull back Release Ring and tilt hone body as
shown
(see Figure 2)
.
2. Pull the ANR-210 Pinion all the way out.
3. Place the racks of the stone and guide assemblies
in holes marked "X" as shown.
4. Put ANR-2l0 Pinion back in place.
5. Pull back Release Ring, line up hone body, and
allow Release Ring to return to engaged position.
CAUTION
Do not mix used stones and guides from different
sets - the guides will be either too tight or too loose,
causing chatter, poor cutting, or other undesirable
results.
TO HONE HOLE
To hone workpiece, proceed as follows
(see Figure
3)
:
1. Place hone in work.
2. Expand stones by rotating handwheel in a
counterclockwise direction (opposite to direction of
hone rotation). When hone contacts wall of work,
back handwheel off one-half turn clockwise.
CAUTION
Hone must rotate in a clockwise direction (as viewed
from power source end).
3. Start hone rotating in work in a clockwise
direction and apply very light stopping pressure to
handwheel as hone is stroked through length of bore.
4. Localize honing in any tight spots and gradually
lengthen stroke as bore becomes straighter.
5. As bore diameter gets larger and stones become
loose, a light braking on the handwheel will keep
the stones cutting.
STROKING
Stroke the hone fast enough to produce a crosshatch
pattern in the hole. At the end of each stroke the
stones should extend approximately one inch (25mm)
out of the cylinder.

FIGURE 2, Assembly
Standard Sunnen Tooling and Procedures will satisfy all ordinary honing requirements. If problems are encountered, they can usually be solved by following procedure suggested below. For detailed information on difficult or unusual honing problems contact your local Sunnen Field Engineer or Sunnen Customer Service Department in St. Louis, Missouri, USA.

For long or repetitive production runs, it may be economical to choose a stone slightly harder or softer, coarser or finer. If the stone wears out too fast, use a harder stone; if it Goes not cut, use a softer stone.)
