1. GENERAL INFORMATION

1.1. Application

The BM-21S Beveling Machine is designed to mill edges of plates and pipes made of

stainless steel. The machine allows beveling sheet edges and edges of pipes with

diameters from 150 mm (6’’) to 300 mm (12’’) at the angle of 0 to 60° and with the

maximum bevel width of 21 mm (13/16’’). The machine contains dampers to reduce

vibrations.

When equipped with an optional guide, the machine allows working on pipes with

diameters over 300 mm (12’’).

2. SAFETY PRECAUTIONS

1. Before beginning, read this Operator’s Manual and complete proper occupational

safety and health training.

2. The machine must be used only in applications specified in this Operator’s Manual.

3. The machine must be complete and all parts must be genuine and fully operational.

4. Theelectricalsupplyspecificationsmustconformtothose specifiedontheratingplate.

5. The machine must be plugged into a properly grounded (earthed) socket-outlet.

6. Never pull the power cord as this may damage it and result in electric shock.

7. Untrained bystanders must not be present in the vicinity of the machine.

8. Before beginning, check the condition of the machine and electrical installation,

including power cord, plug, control panel components, and milling tools.

9. Keep the machine dry. Exposure to rain, snow, or frost is prohibited.

10. Keep work area well lit, clean, and free of obstacles.

11. Never use the machine in the vicinity of flammable liquids or gases, or in explosive

environments.

12. Never use dull or damaged tools.

13. Use only tools specified in this Operator’s Manual.

14. Mount the cutting inserts and the milling head securely. Remove adjusting keys

and wrenches from the work area before connecting the plug to the power outlet.

15. If the cutting edge of an insert is worn, rotate the insert in the socket by 90° or, if

all edges are worn, replace with new insert specified in this Operator’s Manual.

Always replace or rotate all inserts at the same time.

16. Before every use, inspect the machine to ensure it is not damaged. Check whether

any part is cracked or improperly fitted. Make sure to maintain proper conditions

that may affect the operation of the machine.

17. Always use eye and hearing protection, respiratory protective devices, non-skid

footwear, gloves, and protective clothing during operation. Do not wear loose

clothing.

18. Do not touch moving parts or metal chips formed during milling. Prevent objects

from being caught in moving parts.

19. After every use, remove metal chips from the machine, especially from the milling

head. Never remove metal chips with bare hands. Clean the machine with a cotton

cloth without using any agents.

SM-BM-21S

20. Maintain the machine and tools with care. Cover steel parts with a thin grease

layer to protect them against rust when not in use for any extended period.

21. Maintain the machine and replace parts and tools only with the power cord

unplugged from the power outlet.

22. Repair only in a service center appointed by the seller.

23. If the machine falls on a hard surface, from height, is wet, or has other damage

that could affect the technical state of the machine, stop the operation and

immediately send the machine to the service center for inspection and repair.

3. STARTUP AND OPERATION

3.1. Preparing

3.1.1. Adjusting the bevel width and angle

Before starting, set required bevel width and angle. First, with power cord unplugged

from the power outlet, set the milling head penetration to zero. To do this, loosen the

lever (Fig. 2) and rotate the adjusting knob to decrease the penetration of the milling

head into the workpiece by setting the indication ‘0’ on the width pitch.

Fig. 2. Adjusting the bevel width and angle

All safety precautions must be closely observed.

To change the angle of the bevel, use the supplied 6 mm hex wrench to loosen

two side screws. Then, turn the guide in a way to set the required angle on the angle

pitch and tighten the screws afterward.

To adjust the bevel width, use the adjusting knob, proceeding as described before.

The width pitch is only an estimate, because the bevel width varies with angle. For

example, for the angle of 10° the maximum width ‘b’ (Fig. 1) is approximately equal

18 mm (11/16’’), while the width pitch indicates 9 mm (6/16’’). Increasing the

penetration at this angle will distort the bevel. The maximum bevel width (b ≈21 mm,

13/16’’) is obtained for the angle of 45°. The demanded bevel width for the required

angle must be determined experimentally by gradually increasing the milling head

penetration into the workpiece.

3.1.2. Using cutting fluid

Before beveling stainless steel, cover the edges of the workpiece with the supplied oil

in the manner shown in Fig. 3.

3.2. Operating

After setting the bevel width and angle, plug the machine into a properly grounded

power outlet. Then, place the machine vertically on the right side of the workpiece as

shown in Fig. 4 in a way that the milling head does not touch the working edge.

Fig. 4. Machine prepared for work on metal plates

Turn on the power, which will illuminate the power switch (Fig. 5). Then, turn on

the motor using the motor ON switch, press the guide to the plate, and slowly move

the machine close to the edge. Bevel by sliding the machine to the left. Beveling is

performed according to the counter-rotation. The proper feed direction is shown in

Fig. 4. The direction of the milling head rotation is indicated on the motor disk under

the milling head cover.

SM-BM-21 Operator’s Manual

SM-BM-21S

Fig. 5. View of the control panel

The feed rate will depend on the profile and composition of the workpiece. You

can bevel the majority of steels capable of being welded in just one pass.

It is recommended that bevels wider than 12 mm (1/2’’) be accomplished in at

least two or three passes. In this case you use less effort and the process takes less

total time than for beveling in single pass.

To obtain the maximum bevel width (21 mm, 13/16’’) in two passes, the first pass

should be 14 mm wide (9/16’’), whereas for three passes the first one should be

12 mm wide (1/2’’) and the second one 16 mm wide (5/8’’).

If the feed is too fast, the red overload lamp illuminates, indicating motor overload.

Further increasing of the load will trigger the safety circuit and shut down the motor.

In this case, move the tool away from the beveled edge, toggle power switch to

position ‘0’, and after the red lamp turns off, turn on the power again. Operating with

the maximum permitted load (the red lamp flashing) is allowed, but the motor

temperature must not exceed 85°C (185°F). This type of motor can work under high

temperatures, but long-lasting overheating can permanently damage motor windings.

Therefore, after longer working under full load (up to 1 hour), stop the motor to cool it

for 10–15 minutes. Do not cool the motor by running it without load as it will become

heated even faster than when working with load.
