Using the following example we would like to illustrate the economic efficiency of the HBM edge milling machines. A metal sheet is chamfered according to the following data, in order to calculate the arising expenses. Kindly consider that the values taken as a basis refer to the expenses valid in European countries. |

Since the working of profile plates should also be examined as, just the following working options have
been compared:
| Type of machines | tool inserted |
|
angle grinder, 2,3 kW |
Grinding disc Ø 180mm |
|
CNC machining center, 25 kW |
Milling head 45° with inserts |
|
Hand-held bevelling machine HBM 15, 1,8 kW |
Milling head 45° with inserts |

MGS edge milling machines: economic and effective regarding bevels and radii.!
The bevel results were satisfying in all tests. The absolutely best quality was achieved by the CNC machine whilst the fastest
working with very good quality has been attained by our edge milling machine HBM 15. The work with the angle grinder
was inadmissible since it was extremely hard, long lasting and accompanied by extreme stress due to noise and dust.
| The fasted, most effective and thus most economical working on bevels at metal sheets was achieved by our edge milling machine HBM 15 |
