Chiesa CNC Traveling Head Die Cutting Presses
CHIESA’s CNC Traveling Head Die Cutting Systems with 2 or 3 controlled axes are cutting robots, granting power, precision, speed & with the powerful advanced nesting software, maximize material utilization. The Chiesa F1 EDI CNC Traveling Head Press incorporates and electrically servo driven cutting head without the use of hydraulics. This ‘GREEN’ technology reduces power consumption up to 50%, eliminates all the maintenance associated with hydraulic components, and improves overall accuracy, repeatability & production throughout. In addition, to improve overall productivity & material yields, the press is equipped with either a 4 or 14 position automatic tool changing device.
Chiesa pioneered automatic die cutting and developed the first belt fed die cutting press in the late 1980’s & patented the electrically driven (no hydraulics) CNC automatic cutting press in 2006. They are considered the market leader for industrial die cutting applications – particularly for the abrasive, gasket & automotive sectors. The long experience gained in the automatic cutting industry through thousands of installations and the steady dialog with our customers helped in creating a reliable, safe, user friendly performing product.
These die cutting systems are extremely efficient. The robust structure and the quality of mechanical components allow cutting speeds beyond 100 punches per minute, with a precision of a few hundredth of a millimeter, which allows parts to be kept as close as possible, increasing the material savings & cutting belt life.
The cutting power, up to 110 tons, is kept steady even for extremely long production runs allowing these machines to cut hard materials of high thickness, in single or multiple layers, and use multiple dies or dies with long blade development.
Material Feeding Systems
There are a wide variety of modular feeding systems available for both roll & sheets in single and multiple layers including:
Cutting Belt & Feeding Clamps: Suitable to cut any type of synthetic material both in rolls and sheets, loaded both from the front or back of die cutting press; the material is moved and fixed by three independent clamps. One clamp is mobile and supports the belt in the movement of the material to grant the maximum positioning of the material(s) even for soft, elastic products, cut in single or multiple ply.
Mobile Cutting Pad & Clamps: Suitable to cut sheeted goods only, both in single & multiple layers. The sheets are loaded onto a polypropylene cutting pad with automatic movement and equipped with special clamps. The clamps allow the cutting of multiple layers without stapling.
Automatic Sheet Loading: The material is loaded onto a hydraulic platform, both in single or stapled multiple layers. A special vacuum suction cup device grips the material and positions it onto the back of the machine. The feeding system will automatically stop the machine when there is no longer material available. The sheet feed system is available on all models equipped with the cutting belt & clamps. The system can also be equipped with an automatic part unloading device.
Advanced Nesting Software
The software allows to calculate, with considerable precision, for each material consumption and time required (thus labor cost) in order to make accurate simulations of the cutting cost, enabling better production planning and more precise offers to customers. To calculate the best material optimization it is possible to use both a DXF file and a pattern obtained via die digitization. A powerful nesting algorithm quickly & precisely calculates the best possible cutting layout using either a single shape or multiple shapes.
Once the best material optimization is obtained, the graphic image of the result is displayed on the systems touchscreen monitor along with the data relating to the cost of an individual piece or the entire run, the production time, the yield etc. The cutting programs can be transferred to the press either manually (by drive) or automatically via serial connection.
