Fast CNC turret punch press makes its
debut
A turret punch press with higher acceleration and faster sheet positioning, will be shown at MACH 2006, along with CNC press brakes and an inspection machine for checking flat products.
A turret punch press from Finn-Power will be launched, called C6 Compact, capable of punching, nibbling and forming sheet up to 8mm thick over a 3m by 1.5m working area The new construction of the axes allows higher acceleration and faster sheet positioning than has been achievable in the past

Sheet metal punching FMS has two cells
Britain's leading ride-on garden machinery manufacturer, Countax, has installed a GBP1 million sheet metalworking cell in a purpose-built extension to its Oxfordshire factory.
Tube benders need little programming experience
Minimal programming experience is needed to operate the new PC-based 'IMS' control system fitted to the latest Italian-built hydraulic tube bending machines from Pedrazzoli.
Increased operating speed up to 150m/min is promoted by a rack and pinion in the X-axis and a double ballscrew in Y-axis.
Control system is a Siemens Sinumerik 840D.
Standard features are brush tables, central lubrication and PCS - a patented programmable clamping system that automatically prevents them from traversing to an unwanted position.

Laser profiling machine offers linear motor speed
Believed to be the only laser profiling machine to use low-friction linear motors on axis drives, it is able to accelerate at 2G and position within +/-25 micron.
With PCS and an optional third clamp, dead zones can be completely eliminated, allowing 100% utilisation of the material.
Digital punch control, 300kN ram force and 20 station turret (allowing for the possibility of over 120 tools in the turret) ensure versatile, high performance.
Maximum punch diameter is 89mm.
An optional 500mm x 500mm work chute with conveyor retrieves parts directly to a pallet.
The loading device is equipped as standard with sheet separation, double sheet detection and sheet squaring functions.
The C6 turret punch press is also available as an Express unit with automatic loading and unloading and may be connected to all Finn-Power flexible manufacturing systems.
* Press brakes - three Baykal press brakes will be in evidence at the show.
The Turkish-built machines encompasses electronically balanced CNC press brakes, mechanical torsion-bar models and upstroking machines as well as variable-rake guillotine shears and hydraulic swing-beam shears.
Despite having a good price advantage, the machines are of good quality, utilising component parts such as Bosch Rexroth hydraulics, Heidenhain encoders and Delem controls.
* Box folders - for the production of box-type sheet metal components, a range of folding machines employing electromagnetic rather than conventional mechanical clamping of the sheet is marketed by Press and Shear under a sole agency agreement with the Tasmanian manufacturer, Magnetic Engineering.
Magnabend 1250 model will be on show with six tonnes clamping force and 1250mm x 1.6mm capacity.
The machine design is open-ended with unlimited throat depth, allowing the production of large, complex components.
Even aluminium or other non-ferrous materials may be processed, as the magnetic clamping force passes through them and pulls the clamp bar down onto the sheet.
In essence, the machine is a long electromagnet with a steel clamp bar located above it.
The only power needed for operation is a 240V, single-phase supply.
At the press of a button, a sheet metal workpiece is clamped between the bar and magnet.
Operator Safety is enhanced by a two-handed electrical interlock that ensures a safe pre-clamping force is applied before full clamping occurs.
A bend is formed around the front edge of the bar by manually pulling the handle, which when returned to its original position automatically releases the clamping force.
Magnetic clamping means that bending loads are taken exactly at the point where they are generated; forces do not have to be transferred to support structures at the ends of the machine.
This in turn means that the clamping member does not need much structural mass, so it can be made more compact and does not obstruct the bending operation.
Indeed, the thickness of the clamp bar is determined only by the requirement for it to carry sufficient magnetic flux, and not at all by structural considerations.
* Flat components inspection machine - new also at MACH will be a Planar measuring machine manufactured by InspecVision, Northern Ireland, intended for inspecting and reverse engineering flat components produced on power presses, laser or plasma profiling machines, turret punch presses, water jet cutting machines or routers.
Unlike other systems on the market, the inspection machine has no moving parts, allowing it to be sold at an extremely competitive price.
Amortisation periods of less than two years are easily achievable.
Absence of moving parts also avoids wear and the need to recalibrate the machine periodically.
It is almost impervious to vibrations and can be installed on the shop floor, even adjacent to a punching machine.
Manufacturers may therefore carry out first article inspection in seconds, reducing scrap and downtime.
As the system measures a component in less than one eighth of a second, it can be integrated into a high-speed, automated production line, if required.
Available in five models with table sizes from 2.85m2 to 0.35m2, accuracies ranging from +/-0.025 to +/-0.1mm.
A useful feature is the ability to digitise a printed drawing in seconds by converting it automatically into a DXF file, enabling the part to be manufactured on a CNC machine.
The system even includes optical character recognition (OCR) and neural networks to extract text and dimension layers from the drawing.
To create an accurate DXF manually can take hours, or even days.
* CNC bending machine - completing the exhibits will be a horizontally-acting, CNC bending machine from the Swiss manufacturer, Stierli-Bieger.
