Norma E
Double head cutting-off machine with manual movement of the mobile head and position detection by means of an absolute magnetic band. The rotation of the cutting units on the vertical axis (45° to the left and right) and the inclination on the horizontal axis (45° internal), with manual adjustment, allow combined cuts even at intermediate angles.
Technical data
Included
Available
Mobile unit positioning
Positioning of the mobile unit is done manually by turning the handling handwheel, and position detection is done by the direct measuring system with absolute magnetic strip. When the mobile head reaches the correct position for the cut to be made, the operator is notified by a green warning light located next to the handwheel.
Control
The control panel, installed on a support sliding on bearings along the front side of the machine, allows correct mobile heads positioning in accordance with the required cutting schedule. The interface uses a 7” touch-screen and fully personalised software and is packed with bespoke functions that are unique to this machine. The machining cycle can be optimised by creating cutting lists, thereby reducing scrap and cycle times for parts loading-unloading.
Heads rotation
In addition to tilting with respect to the horizontal plane, the two cutting units rotate with respect to the profile support square. This movement allows positioning from -45° LH to + 45° on the vertical axis in relation to the 90° cutting position, including intermediate angles. This allows compound cuts to be made by combining tilting and rotation of the cutting unit.
Heads tilting
The two cutting units, assembled on the relevant carriages, consist of a blade holder unit that can be positioned, with respect to the profile support surface, with 90° to 45° tilting towards the inside. The intermediate tilting angles can be set by means of a manual adjustment system, which allows a wide range of compound cuts to be performed in combination with the rotation of the cutting units. The two cutting units are equipped with mechanically-controlled local protections of the machining area.
Horizontal and vertical vices
The machine has pneumatically controlled horizontal and vertical vices, equipped with a low-pressure device that eliminates risks to the operator by allowing high-pressure clamping only when in a safe condition. Vice position can be manually adjusted to ensure that the profile is correctly clamped in the machine.
Manual intermediate support
The manually adjustable intermediate support is extremely useful for loading and unloading workpieces; it also provides support for the bar, preventing it from deforming when cutting particularly long workpieces with very flexible profiles. A plastic roller is mounted on the intermediate support which, properly positioned, provides perfect support for the profile. The intermediate support can be removed when not needed.
