Abstract: A key duplicating machine includes: a support structure, a front operational area which is accessible by the operator and which is removably covered and separated, at least partially, from the external environment by a covering and/or protection crankcase movable with respect to said structure of support. At least one key cutter and/or another cutting element, and at least one terminal (12) for locking a key, are housed in the front operational area, a rear containment area, covered and separated from the external environment by a casing mechanically fixed to the support structure, and a control and command unit having a mechanism for moving said crankcase for covering and/or protecting the front operational area, the crankcase being configured to be mounted on a fixed structure of the duplicating machine so as to be able to be moved with respect to the fixed structure.

Abstract: A key-cutting machine includes: a support structure; a front operational area which is accessible by an operator; at least one milling and/or cutting unit which is positioned in the front operational area and which includes at least one end mill, and/or another cutting member, to carry out a bitting processing of a key. The key-cutting machine also includes at least one clamp, which is positioned in the front operational area, to hold the key to be machined, so that a face of the key to be engraved is arranged substantially horizontally. The key-cutting machine also includes a device for engraving at least one face of the head of said key, said device being positioned inside the front operational area of said duplicating machine; and at least one pair of engraving tools mounted on a support unit. Each engraving tool includes cutting sections for engraving a corresponding face of a key.
