4. Choosing A Groove Type
Before grooving a lens you must decide what type of groove is needed. Lift the setting table and
set the control settings on the underside in accordance with the desired groove type.
7
Amcon Auto Groover
A. Center Groove – Used for plus lenses or thin lenses with uniform edge thickness.
The Center Groove setting is the most commonly used method for plus lenses. In this mode,
the groove is automatically centered between the front and rear surfaces of the lens.
1.
Lift the setting table (Fig. 1) and plug the coupling pins into the lower two holes
marked “C”. Lower the setting table.
2.
Install the center pin between the guide arms.
3.
Adjust the groove locator to the center.
8

B. Front Curve Groove – Used for high minus lenses with high cylinder curves.
High minus lenses, particularly when combined with strong cylinders look best when the
groove is based on the front curve of the lens. The groove should be close and equidistant to
the front surface but not less than 1.0 mm. Use Fig 2B and proceed as follows.
1.
Lift the setting table (Fig. 1) and plug the coupling pins into the “F” and left “C”.
Lower setting table.
2.
Remove the center pin and let it hang.
3.
Chuck up the lens, lower it on to the lens acceptor (Fig. 1) and allow it to rotate until
the thinnest part of the edge is directly on the lens acceptor.
4.
Turn the groove locator so that the lens edge moves over the slot to the position that
will cut the groove at the distance from the front edge that you desire.

C. Rear Curve Groove – Used on Executive Bifocals.
This setting is seldom used for normal lenses but it is very useful if you are attempting to
groove a lens that has an interrupted lens edge such as those found on Executive Bifocals.
Use Fig. 2C as a guide when setting up the machine.
1.
Lift the setting table (Fig. 1) and place the coupling pins into the “R” and right “C”
positions. Lower setting table.
2.
For a normal lens simply use the same operating procedure as above for a front curve
groove only setting the groove locator knob to the left.
3.
If grooving a lens with an interrupted edge, adjust the left guide arm to place the
lens so the groove is set at the desired position.
4.
While pressing gently on the right side of the machine head, (Fig. 1) lower the setting
table to the desired groove depth and then turn on the lens switch (Fig. 1). Hold the
right guide arm away from the front surface of the lens so that the interrupted lens
edge does not catch on the right guide arm.

5. Grooving A Lens
After your Amcon Auto Groover has been set up for the desired type, use the following
instructions to groove the lens.
NOTE: If you wish to create a deep groove on a hard glass lens, first set the depth dial to half of
the final depth and after the lens being grooved has made one revolution (approx. 40 seconds),
adjust the depth dial again to the final depth for another revolution of the lens.
1.
The depth dial should be set to zero, both switches in the off position. (See Fig. 1 for
location of controls.)
2.
Place the sponge between the two upright plastic septums directly under the setting
table. Use the accessory plastic syringe to wet the sponge liberally with tap water (no
other coolant is needed). Do not add too much water.
3.
Lower the setting table to its operation position and chuck-up the lens approximately
in the center. Tighten the chuck knob finger-tight plus a quarter-turn. Always make
sure that the front of the lens faces to your right.
4.
Open the guide arms and gently lower the lens between the two nylon guide rollers
onto the lens acceptor.
5.
Check to be sure everything is set correctly, then turn the lens switch to the ON
position. Allow the lens to rotate about a quarter-turn and check to see that it is
snugly between the rollers.
6.
Turn on the cutter wheel switch.
7.
Turn on the depth dial to the setting you prefer.
11

8.
After approximately 40 seconds, the sound from the cutter will change indicating that
the lens is finished. Turn off the cutter wheel switch and then the lens switch and
raise the machine head.
CAUTION: Before grooving glass lenses you must first refer to the safety rules and regulations
in your area for glass lenses.

6. Adjustments
Groove Position Adjustment When Using The Center Groove Mode
This is a fine adjustment of the position of the groove produced in the center curve mode.
To move the groove to the rear face of the lens, turn the adjusting knob clock-wise. (Fig. 4) to
move the groove to the front face of the lens, turn the adjusting knob counterclockwise. (Fig. 4)
Depth Adjustment
To check that the “0” position is correct, set the depth dial to “0” and see whether the cutter
wheel protrudes above the surface of the lens acceptor. If it isn’t, adjust the zero adjuster screw
located at the end of the setting table. (Fig. 1).
Removal Of The Setting Table
To remove the setting table (Fig. 1), insert a small diameter metal rod into the hole that is located
on the right side of the setting table shaft. This is a two piece screw design, screw the end point
of the shaft into the body of the main shaft.

7. Maintenance
Water Drain
The Amcon Auto Groover has a small drain located in the front wheel well (Fig. 1). A plug is
installed in this drain to prevent accidental spills. We strongly recommend permanently
removing this stopper so that you never accidentally allow too much water to accumulate, which
could lead to bearing failure. Bearings are not warranted against damage from exposure to
water.
Sponge
Wash the sponge frequently to rid it of entrapped particles and wet it liberally before each use.
Change the sponge when it appears worn. At the end of each day’s use, take the sponge out and
rinse it thoroughly.
Slide Shaft
Clean the slide shaft frequently with a clean cloth and occasionally place a small a small dab of
white grease on the shaft surface to make sure that the machine head moves side-to-side freely at
all times (Fig. 1).
Replacing the Cutter Wheel
To replace the cutter wheel, first unplug the power cord and put a narrow rod in the hole of the
shaft and then undo the Phillips wheel lock screw.
14
Amcon Auto Groover
CAUTION: The cutter wheel must be replaced correctly (Fig. 3) so that it fits into the slot of the
lens acceptor (Fig. 1)
Replacing Chuck Rings
Open the lens chuck and remove the left chuck followed by the right chuck (Fig. 1). You can
then remove the chuck rings easily and snap in a new pair.
Replacing Carbide Motor Brushes
1.
Turn the machine up side down and remove the 3 recessed Phillips head screws and
remove bottom cover.
2.
Roll belt off pulley.
3.
Check to see if the brushes need changing by removing the front brush. To remove
the front brush, unscrew the black Phillips head screw cap on the side of the motor
housing. Pull the spring out. If the carbide tip on the end is short replace it.
4.
To remove the back brush, detach the motor from the mounting bracket by removing
the two nut screws. Unscrew the black Phillips head screw cap on the motor housing
and remove. Pull the spring out and replace with a new brush.
5.
Reinsert black Phillips head screw caps and remount motor housing to the mounting
bracket.
6.
Replace cover and 3 recessed Phillips head screws.
