CNC punch and shear saves metals costs

The built-in shear on a CNC punch press has gained popularity, since steel prices started to rise steeply, as the technique can save typically 10% in material consumption.
A new model in the Finnish-built range of combination turret punching and right angle shearing machines from Finn-Power, marketed under the ‘Shear Genius’ brand name, has been introduced to the UK by Press and Shear Machinery, Tamworth.
Designated SG6, the compact cell can machine larger sheet up to 3000 x 1500 mm without repositioning.
Higher productivity results from 30 rev/min rotation of the 20-station turret, an indexable forming option, and 150m/min table positioning in each axis, facilitated by a double ballscrew drive in Y and a high precision rack and pinion in X.
The concept of a built-in shear has gained popularity in recent years, particularly since steel prices started to rise steeply, as the technique results in savings of typically 10% in material consumption compared with traditional machining methods.
Other characteristics of integrated shearing are high quality edge finish, high sheet utilisation, and easy programming leading to short set-up times.
Stroke depth is automatically adjusted for maximum shearing speed.
In the new Shear Genius, sheet squaring is fast as it takes place on the machine table; no auxiliary table is needed.
Accuracy has been improved by the new actuation mechanisms for X and Y movement and by the introduction of an optional programmable fourth clamp.
There is also the option of a large work chute.
Fast, servo electric loading of sheets up to 200kg minimises idle times and double sheet checking is integrated into the gripper.
After machining, automatic component sorting and stacking may be performed by a variety of modular Finn-Power solutions.
There exists also the ability to transfer parts robotically to a bending cell or a press brake, allowing an even higher degree of automation.
Thus Shear Genius SG6 combines 300kN hydraulic turret punching and optional forming and tapping with high-quality shearing for separating the components rapidly, coupled with many automation possibilities.
Unlike in laser cutting, only electrical and compressed air supplies are required, while edge quality is more than sufficient for the vast majority of jobs.
There are very few components that cannot be produced economically.
