Beveling Depth Adjustment
1. Set the appropriate beveling depth by loosening or
tightening the adjustment handle on the upper
position (List No. 16), watching the scale on the right
side of the frame.
2. One rotation of the adjustment handle changes the
beveling depth by 1.25mm. One rotation is divided by
eight clicks, each click changes the beveling depth by
about 0.16mm. At this time, actual beveling depths of
the plates will have the characteristics in the following
drawings, according to the beveling angles. (Please
refer to the illustrated cases below)
12. It is recommended to connect the air valve(provided) to the Frame(List No. 21) for cooling
down while continuous operation.
13. Be sure to use 20 degrees insert tips only.
14. When all the parts of the machine are not assembled at a normal condition, including at
time of repairing works or replacing insert tips, be sure to unplug the power cord.
15. This machine should be used only by workers who have read this User’s Manual and
understand these safety cautions.
16. This machine should be used under the work scope suggested by the specifications.
17. Safety cautions should be kept at all times during daily works. When needed, the

Beveling Angle Adjustment
Work Procedure
Turn the End Cap (List No. 26) holding the V-block
(List No. 28, 30) by loosening 4 hexagonal cap
screws (List No. 27). Adjust the beveling angle,
watching the scale on the left side. After that, tighten
the 4 hexagonal cap screws completely. (Check
whether the beveling angle is accurate by measuring
with the goniometer after a small test beveling work.)
1. Be sure to wear safety goggles and ear protection kits at work.
2. Hold the D-Handle (List No.15) with the right hand and hold the motor switch handle
portion with the left hand while working.
3. To adjust the height of the motor switch held by the left hand of each worker, loosen the
locking bolt (List No. 13), adjust the height and then tighten it again.
4. The motor switch is designed by 2 step structure, for safety purpose. The motor is started
by pushing the red button forward. At this time, the switch is locked and set at a
continuous mode. To turn off the motor, push and release the long black switch underneath.
5. Start the motor first and then approach to the workpiece. Move the machine slowly from
the top and chamfer the workpiece from left to right.

6. Always chamfer the workpiece from left to right. Do not move the machine backward,
always move it forward.
7. Always start beveling from the edge of the workpiece. If you would like to start beveling
from the middle, you have to approach the machine to the workpiece very slowly to
prevent the damages on the insert tips.
8. The beveling speed depends on the beveling depth and beveling angles. (different beveling
quantity) It is recommended to adjust the beveling speed as per the beveling quantity. Do
not operate the machine with excessive speed.
9. It is recommended to replace the insert tips when they are worn, dull or damaged.
Excessive use may cause damages on cutter heads and the machine itself, thereby cause
shorter lifetime of the machine by the excessive power exerted on the machine.
13. When replacing the insert tips or doing repair works, be sure to separate the power cord
from the power source. In particular, never start operating the machine when the locking
bolt (List No. 13) is loosened and the frame (List No. 21) is separated.
14. When assembling parts of List No. 8, 9, 10, do it with 3mm hexagonal T-handle wrench as
illustrated below. At this time, turn the insert set screws continuously clockwise so that the
right-hand screws of the cutter body and the left-hand screws of the wedge could be
assembled together at the same time. When the inserts are completely assembled, adjust
the length of the left-hand screw or right-hand screw so that the head of the insert set
screws to be placed below the upper surface of the wedge.
For CP1000, set the inserts to be placed at the center of the cutter wedge.
For CP2100, set the inserts to be placed at the center of the two cutters facing each other.
10. Only 20 degrees insert tips should be used.
11. When replacing the insert tips, use 3mm
hexagonal T-handle wrench and tighten the
screw(Parts No.8) while pressing the tip
toward the center of the cutter, so that both
the bottom face of the tip and the seat of the
cutter are completely in contact.
12. When the screw (List No. 8) is not easily
loosened to replace the insert tips, do not
turn it with excessive power. Instead, loosen
the bolt (List No. 13), separate the whole
frame (List No. 21) and then loosen the jam
nut (List No. 11). After separating the cutter
(List No. 6), strike the insert tips with an
penetration screwdriver to remove them.
This makes the loosening work of the screws
easier to replace the insert tips.

15. Each insert tips have 4 cutting edges and could be used 4 times by rotating the inserts.
16. The insert set screw (List No. 8) is Kyocera Korea Precision’s product.
17. The insert tip (List No. 10) is Kyocera Korea Precision’s product.
.This product is coated by titanium and the part numbers are as below :
•Part No. : PP9130 SECN120308-AHA-IC
* The wearing rate of these inserts depends upon the materials to be beveled.
* Note : In case the beveling width is not so big, (less than 5C) the following insert tips could
be used for CP-1000 only.
A. KORLOY : PC9530 SEKR1203AFSN-MX
B. TaeguTec : TT8020 SEKN1203AFTN-EM
C. Kyocera : PR730 SEKN1203AFTN
18. Use of cutting oils (tapping oil, vegetable oil, etc.) could be helpful for the improvement
of the beveling speed and longer life of insert tips. In addition, by providing
compressed air by attaching air valve in the center of the frame (List No. 21), the life of
the insert tips could be longer by preventing the insert tips to become too hot.
19. When beveling the surface of a workpiece which is cut using heat, because of the
hardened surface, the life of the insert tips will be shorter.

How to bevel outside diameters of pipes
1. The sizes of the diameters which could be handled by this machine is more than 6 inches.
(150A) It is also possible to handle outside diameters of round plates with this machine.
2. When you do the beveling work with shorter pipes, it is easier for you to erect the pipes
and do the work by putting the Chamfer-Pro on top of the pipes. For longer pipes, you
can do the beveling work by laying down the pipes and do the work on top of the pipes,
by rotating the pipes.
However, if the pipe is very long, you cannot do the work in an easy and fast way. In these
cases, you can do the beveling work in an easy and fast way if you use our exclusive pipe
beveling machines MP0020(Manual Pipe Beveling Machine) or AP1020(Automatic Pipe
Beveling Machine).
3. When you do the beveling work by erecting the pipes, install the Roller Guide (List No. 31-
33, optional item) on the left-hand side groove of the Large Plate of the V-Block (List No.
30) and set the Roller Guide to be positioned inside of the pipes. After that, put the
Chamfer-Pro on the pipe and fix the Roller Guide on the appropriate spot of the groove of
the Large Plate, so that the machine could rotate easily along the circumference of the
pipes. The purpose of this is for the easier beveling work and the beveling depth should
be set below zero (0) level at this time, which means doing the test without turning on the
switch of the electric power.
4. When you do the beveling work by erecting the pipes, you should set the intended
beveling angles to be 90 degrees minus beveling angle on the scale. That is to say, if you
would like to do 30 degrees beveling, set the angle 90 degrees minus 30 degrees = 60
degrees. If you want 37.5 degrees beveling, set it at 90 degrees minus 37.5 degrees = 52.5
degrees.

How to convert from CP-2100 to CP-1000
1. Purpose
When you would like to chamfer thin steel plates, (less than 7mm thick) it is
recommended to convert from CP-2100 to CP-1000 to save working time since CP-1000
requires only 6 inserts, while CP-2100 requires 12 inserts.
2. Difference of CP-1000 and CP-2100
The difference of CP-1000 and CP-2100 is the difference of number of cutter heads.
CP1000 has one cutter head while CP2100 has two cutter heads.
Other specifications like motor performance and frames are the same for both CPs.
3. How to convert
In order to convert from CP-2100 to CP-1000, loosen the bolt (List No. 13) and remove
frame (List No. 21) and List No. 12, 11 and 6 parts in sequence. After that, assemble Shim
(List No. 7-1) first and then reassemble List No. 6, 7-2, 11, 12 and 21 parts in sequence
and tighten the bolt (List No. 13).
5. When you do the beveling work by laying down the pipes, disassemble the Large Plate
(List No. 30) and Small Plate (List No. 28) from the End Cap (List No. 26) and change the
positions and assemble them again. After that, install the Roller Guide (List No. 31-33) on
the Large Plate (List No. 30) and do the beveling work. When you do the beveling work by
laying down the pipes, you should set the intended beveling angles by setting the same
degrees on the scale of the machine. That is to say, if you want 30 degrees beveling, set
the scale at 30 degrees.
6. To secure the stability of the beveling work, if needed, you can put another Roller Guide
(List No. 31-33) on the groove of the right-hand side of the Large Plate of the V-Block (List
No. 30).
7. As per the size of the diameters of the pipes, you can install the Roller Guides either on
the left side only or on both sides. The positions of the Roller Guides could be either
inside or outside of the pipes, as per the sizes of the diameters.
8. When you start the beveling work, do the test beveling first, which means that start with
shallow beveling and then increase it to the intended beveling depth.
9. In order to prevent damages of the insert tips, always approach the machine slowly to the
workpiece in the beginning.
Chamfer-Pro User’s Manual - 11 - AHA Industrial Co / www.ahaind.com

Usage of Built-in Speed Controller
1. Purpose
The Chamfer-Pro motor has a built-in speed controller that can be operated from
level 1(1800 RPM) to level 6(5850 RPM) speed without load. (Depending on load
amount when beveling)
To longer the life of the inserts, the RPM can be adjusted according to the type of
materials to be beveled for efficient beveling, and especially for the stainless steel.
2. How to use
a. Adjust the appropriate RPM by referring to the speed indication attached to the
motor body.
b. When you bevel stainless steels, it is recommended to set the Speed Controller
from level 1 to 3 as per the actual load.
c. At higher level of speed, the beveling speed is faster but the wearing rate of inserts
are faster, while at very lower level, wearing rate of inserts are slower but beveling
speed is slower and may cause vibrations on the machine.
d. Stainless steels with higher tensile strengths (STS 304, STS 310, STS 316, etc.) have
faster wearing rate of the inserts.
Chamfer-Pro User’s Manual - 12 - AHA Industrial Co / www.ahaind.com

1. Purpose
When you do the beveling work, you need to
do the work by sticking the Big Plate of the V-
Block (List No. 30) to the workpieces. However,
the surfaces of the workpieces may not be
smooth enough to do the beveling work
because of bad surface smoothness, rusts and
dirt. In these cases, the friction between the V-
Block Plate and workpieces become very big,
thereby making it difficult to do the beveling
work. This optional item, Roller Plate, enables
easier and faster beveling work by decreasing
the friction.
Usage of Roller Plate
2. The differences between standard V-Block Plate and Roller Plate
The total length of standard V-Block Plate is 224mm. When you chamfer both edges of
workpieces, it is needed that minimum 112mm of the workpieces should be contacted to
the V-Block Plate. In the meantime, the total length of the Roller Plate is 264mm and it is
needed that minimum 264mm of the workpieces should be contacted to the V-Block
Plate.
3. Other aspects of Roller Plate
In order to achieve even beveling results on both edges of the workpieces, it is
recommended to install extension plates (approximately 140mm) on both edges of
workpieces to stabilize the Roller Plate, as illustrated below, thereby enabling even
beveling results and better workability.

4. Using Supplementary 1t plate of the Roller Plate
In order to supplement the above 2 and 3 explanations, by using 1t supplementary
plate with the Roller Plate, the beveling work on both edges of the workpieces could be
much easier. Since the difference of height of the rollers of the Roller Plate and
workpieces is 1mm, by inserting supplementary 1t plate to the Roller Plate at the starting
point and ending point of the work, you can improve the stability of the beveling works.

Chamfer-Pro User’s Manual - 14 - AHA Industrial Co / www.ahaind.com

1. Purpose
a. When the workpieces are thick and beveling
quantities are big, it is not easy for the workers
to press the beveling machine continuously. If
you use Roller Clamp, the beveling work
becomes much easier and much more
convenient.
b. At times of K type welding or X type welding,
you need to chamfer the downside of the
workpieces. However, if the workpieces are very
long and big, it is not easy to turn upside down.
In these cases, this Roller Clamp enables the
beveling work from downside without reversing
the workpieces.
2. How to install
Remove the Big Plate of the V-Block (List No. 30)
and install Roller Plate instead on that spot.
Remove Small Plate (List No. 28) and install
Clamp instead on that spot.
3. How to use
a. Adjust beveling Depth Adjustment Handle (List
No. 16) so that the beveling value is set at less
than zero (0) level. Widen the distance of the
Roller Plate and the roller of the Clamp by
turning the Roller Height Adjustment Handle of
the Clamp anticlockwise. After that, stick the
whole Roller Clamp to the workpiece completely
and turn the Roller Height Adjustment Handle
clockwise so that roller is stuck to the workpiece.
Keep on turning the handle clockwise so that the
roller could be completely stuck to the workpiece
by the power of the spring inside.

b. Turn on the switch of the motor of the beveling machine and set the beveling value by
turning the beveling Depth Adjustment Handle (List No. 16) and do the beveling work.
c. If you would like to do the beveling work as explained in item 1-a above, you need to
put the Roller Plate on the upside and put the Clamp on the downside. At this time, the
Roller Height Adjustment Handle faces bottom and the beveling work should be done
from left to right.
d. If you would like to do the beveling work as explained in item 1-b above, you need to
put the Roller Plate on the downside and put the Clamp on the upside and the Roller
Height Adjustment Handle should face upward. The beveling work should be done from
right to left.
4. Other aspects of Roller Clamp
a. When you do the beveling work using Roller Clamp, it is possible for you to do the
work of the starting point and ending point of the workpiece only when you install the
supplementary extension plates which can be connected to the edges of the workpiece.
(Please refer to the example cases we explained in number 3 item of Roller Plate in
page 12)
b. When it is difficult for you to install the supplementary extension plates explained in 4-
a. above, you can do the beveling work of the starting point and ending point by using
1t supplementary plate as explained in item 4 of Usage of Roller Plate. However, this
method could be applied only to normal beveling done from upside explained in 1-a,
the Purpose of Roller Clamp and cannot be applied to downside beveling explained in
1-b above.
c. When you do the beveling work using 1t supplementary extension plates explained in
4-b above, you need to have the roller of the Clamp not to be touched to the
workpiece.
