1. GENERAL INFORMATION
1.1. Application
The BM-18 is a beveling machine designed to bevel plates and pipes made of steel,
aluminum alloys, brass, or plastics.
Depending on the milling head, the machine allows you to bevel at the angle of
22.5°, 30°, 37.5°, 45°, 50°, 55°, or 60°. The minimum workpiece thickness is 0.08” (2
mm). The maximum bevel width is 11/16″(18 mm). A radius milling head allows you
to bevel with a radius of 2, 3, 4, or 5 mm. The minimum diameter of a hole to be ma-
chined is 1.57” (40 mm).
An optional attachment allows you to bevel pipes and a sticker protects aluminum
workpieces from scratches. A worktable fixture allows you to bevel flat bars.
The machine is designed for professional use only.

2. SAFETY PRECAUTIONS
1. Before using, read this Operator’s Manual and complete a training in occupational
safety and health.
2. Use only in applications specified in this Operator’s Manual.
3. Make sure that the machine has all parts and they are genuine and not damaged.
4. Make sure that the specifications of the power source are the same as those spec-
ified on the rating plate.
5. Do not carry the machine by the cord and do not pull the cord. This can cause dam-
age and electric shock.
6. Keep untrained bystanders away from the machine.
7. Before each use, ensure the correct condition of the machine, power source, power
cord, plug, control parts, and tools.
8. Before each use, make sure that no part is cracked or loose. Make sure to maintain
correct conditions that can have an effect on the operation of the machine.
9. Keep the machine dry. Do not expose the machine to rain, snow, or frost.
10. Keep the work area well-lit, clean, and free of obstacles.
11. Do not use near flammable materials, or in explosive environments.
12. Use only tools specified in this Operator’s Manual.
13. Do not use tools that are dull or damaged.
14. Make sure that the cutting inserts and the milling head are correctly attached. Re-
move wrenches from the work area before you connect the machine to the power
source.
15. Do not use the machine so that the milling head points up.
16. If the cutting edge of an insert is worn, turn all inserts by 90° or 180°. If all the
cutting edges are worn, install new inserts specified in this Operator’s Manual.
17. Use eye and ear protection, non-skid footwear, and protective clothing. Do not use
loose clothing.
18. Do not touch chips or moving parts. Do not let anything catch in moving parts.
19. After each use, clean the machine and the milling head with a dry cotton cloth and
no chemical agents. Do not remove chips with bare hands.
20. Maintain the machine and install/remove parts and tools only after you unplug the
machine from the power source.
21. Repair only in a service center appointed by the seller.

22. If the machine falls, is wet, or has any damage, stop the work and immediately
send the machine to the service center for check and repair.
23. If you are not going to use the machine, remove it from the work area and keep it
in a safe and dry place.
24. If you are not going to use the machine for an extended period, put anti-corrosion
material on the steel parts.

4.3. Adjusting the guide for beveling with radius
Unplug the power cord. Loosen the clamping screw and turn the sleeve to align the
surface (1) with the end of the cutting edge (2). You can also use an optional radius
insert positioner to set the guide correctly. Tighten the clamping screw. Bevel a test
edge and if necessary adjust the position of the guide again.
4.4. Preparing
Install a milling head with the cutting inserts, and set the required bevel width. Then,
use the speed dial to set the speed that matches the type of the workpiece.
Material type
Rotational speed
Aluminum, brass, plastics
Setting 6
(5850 rpm)
Structural steel of standard quality, quality steel
Settings 3–5
(3100–4500 rpm)
The speed dial allows continuous control of the rotational speed in the range of
1800–5850 rpm.

4.5. Operating
Connect the machine to the power source. Put the machine on the left as shown in the
figure. Make sure that the workpiece is stable.
To start the motor, press and hold the switch lock (1) and the ON/OFF switch (2),
and then release the lock. Wait until the speed is at the required value. With two hands
press the machine to the workpiece. Then, slowly move the machine to the edge (3)
until the tool starts cutting. Move the machine from left to right (4).
Start with making small widths (3–4 mm, 0.12–0.16″) and increase them with ex-
perience. Bevel in at least two passes. Set the bevel width to a value that will allow the
feed of 1 m/min (3 ft/min) without using too much force.
If an overload occurs, the motor stops. This can happen when the bevel width is
too large for the hardness of material or when the cutting inserts are dull. Thus, to
prevent overload, machine hard materials in multiple passes and replace the inserts
before they become dull. Also, take periodic breaks during work and keep the air vents
unclogged. This prevents motor overheating and damage to the windings.
After the work is finished, release the ON/OFF switch to turn off the motor. Then,
wait until the rotation stops and unplug the power cord.
Clean the machine with a dry cotton cloth and no chemical agents.

4.6. Replacing the cutting inserts
Unplug the power cord. Loosen the screw (1) and turn the sleeve (2) to lower it as far
as possible and get access to the milling head. Use the T15 torx screwdriver to remove
the cutting inserts (3, 4). Clean the sockets.
To change the cutting edge, remove the inserts and turn them by 90° or 180°.
Then, push them to the sockets and tighten. If all the cutting edges are worn, install
new inserts. Make sure that the bottom of each insert is in full contact with the socket
(5).
Every week clean the threads of the mounting screws for inserts and put the sup-
plied grease on the threads.

4.7. Replacing the roller
4.7.1. Replacing the beveling roller
Unplug the power cord. Remove the circlip and the roller.
To install the roller, use such a number of 1 mm, 0.5 mm, and 0.2 mm washers to
set the gap to 0.2–0.6 mm between the roller and the cutting inserts. The number of
washers needed depends on the milling head. Put all unused washers between the
circlip and the roller.

Unplug the power cord. Remove the circlip and the roller.
To install the roller, use such a number of 1 mm, 0.5 mm, and 0.2 mm washers to
keep a small gap between the roller and the cutting inserts. Make sure that the roller
turns freely.

4.8. Replacing the brushes
Every 200 work hours, check the condition of the carbon brushes. To do this, unplug
the power cord, and then remove the cap and the brush. If the brush is shorter than
10 mm (0.4″), replace the two brushes with new ones.
Install in reverse sequence. Then, let the motor operate with no load for 20
minutes.

Turn the sleeve to set ‘0’ on the scale (1). Use the 6 mm hex wrench to loosen the
rollers (2) and move them away from each other as far as possible. Put the pipe verti-
cally and put the machine onto the pipe. Press the roller (3) to the pipe and move the
rollers (4) equally to the pipe. Tighten the rollers in this position. Next, move the ma-
chine from the pipe and set the required parameters (5). Then, start the machine,
slowly move it to the pipe, and bevel in the direction (6).
