Cnc Machines

As well as laying claim to be one of the world’s fastest punching machines, CNC punch press system features ‘twin-cart’ load/unload systems resulting in a very compact automated set-up.

With up to 1,200 strokes per minute during punching operations and 2,800 strokes per minute when inscribing, the Trumatic 5000 R is one of the fastest punching machines in the world.

At the EuroBLECH trade show, Trumpf introduced many of the machines new functions that will make the automated operation and production considerably easier.

Adaptive stroke calibration – finished part with the first stamp – when it comes to stamping and forming, fluctuations in sheet thickness have a huge impact.

Now, Trumpf has a simple solution – adaptive stroke calibration.

It garantuees, also in large-scale or recurring series with small batch sizes, a consistent parts quality.

Once its recorded the finished part can now be reproduced at any time, using the same tool.

Parts can even be produced on a different machine as long as this machine has the adaptive stroke calibration feature.

With this newly patented function, the actual thickness of the sheet metal clamped onto the machine can be recorded with an accuracy of 0.03mm and the slide stroke precisely calibrated to the current sheet thickness.

Fluctuations in sheet thickness are therefore automatically compensated for.

The user has the option of making the adjustments manually as often and wherever the tool records the sheet thickness.

Measuring takes only three seconds.

The new accessory is available for new machines of the Trumatic 5000 R, Trumatic 3000 R and Trumatic 3000 L series.

Twin carts: simple automation – to load and unload sheets and finished parts parallel to the uptime, users can additionally equip their punching machines with the Trumalift SheetMaster with twin carts.

TwinCarts are an alternative to the double cart that moves on tracks.

Instead of moving on tracks, TwinCarts move on fixed guides mounted directly into the floor.

It is therefore unnecessary to install and cast running rails.

The guides come in two fixed lengths ? either 5 m for medium-sized systems or 6.5m for large-scale systems.

Since the engines for the TwinCarts are installed at the end of the guides and not, as had been the case, on the double cart itself.

It is also unnecessary to lay and install flexible cable conduits.

The drive train is made up of a shaft and toothed belts.

Since its easy to assemble the guides, TwinCarts costs are considerably lower than for the double carts, and they can generally be assembled in one to two days.

The TwinCarts are a cost-effective alternative to the individually adjustable double-cart system.

Racking cluster tooling produces precisely positioned mounting holes In electronic enclosure racks – including a protusion feature that facilitates easy installation of racks.

Mate Precision Tooling’s 19-inch Racking Cluster tooling fabricates mounting holes in electronic enclosures with a special feature that makes rack positioning fast and easy.

Designed for punching industry standard 19in enclosures, Mate’s Racking Cluster tooling consists of a punch, stripper and die assembly.

The punch is a solid cluster of three punch points on 0.625in (15.87mm) centers.

The two outer punches are 0.375in square (9.50mm) while the middle punch of the same size has a special protrusion on two sides.

When the turret press is programmed to move the sheet to be punched in 1.750in (44.45mm) increments, the correct hole pattern is punched precisely and quickly.

The center punch ‘protrusion’ feature produces a positioning and centering slot that facilitates accurate and easy installation of racks into 19-inch wide punched enclosure boxes.

Mate’s 19-inch Racking Cluster punching process is much faster than single point punching and is in accordance with international standards DIN 41494 and IEC 297.

In addition to the 19-inch enclosure hole pattern, Mate’s Racking Cluster tooling is also available in custom hole shapes and sizes for non-standard applications.

The tooling is available in multiple tooling styles including fully guided design and is available for all popular turret punch press models.

These include Amada, Finn Power, Murata Wiedemann, Euromac, Pivatic and Strippit machines.

A new tooling system for Trumpf presses combines the economy of conventional Trumpf style tooling with features that eliminate the need for alignment fixtures for tooling set-up.

Mate Precision tooling is introducing a new tooling system for Trumpf presses that combines the economy of conventional Trumpf style tooling with features that eliminate the need for alignment fixtures for tooling set-up.

Called QuickLock, the new Mate tool system features a keyed alignment ring that engages the alignment key in the punch for fast tool alignment.

The press operator performs this simple operation quickly by hand.

Tool components snap together without having to resort to off-line, time-consuming alignment tool set-up fixtures.

This reduces set-up time and maximises machine productivity.

Mate’s QuickLock Tooling Is A full-featured system Mate’s QuickLock tool system consists of precision designed and manufactured punches, strippers and dies available in two sizes.

Size 1 has a maximum die opening of 1.181 + 0.078 (30.00 + 0.80).

Size 2 has a maximum die opening of 3.000 + 0.078 (76.20 + 0.80).

Both sizes of tool use the same alignment ring, to reduce tooling inventory, increase flexibility, and maximize productivity.

Tooling is available in eleven standard shapes including: round, rectangle, oval, square, and triangle.

A comprehensive range of special shapes is also available.

The QuickLock punches are made of highly wear-resistant, high speed steel for precision punching and extended intervals between sharpening.

The hardened and ground key, designed for quick and accurate punch alignment, is located on either the shoulder or shank, depending on punch point size.

Punches also have a 1/4-degree back taper and near polished punch flanks to reduce friction, eliminate galling and extend punch life.

For extreme applications, these punches are available with Mate’s Maxima coating or Nitride treatment.

Mate’s QuickLock urethane strippers provide positive, on-the-die stripping to eliminate sheet rattle and reduce punching noise.

These urethane strippers also protect the part being punched, especially decorative materials that could be damaged by conventional metal strippers.

They are available in push-on and screw-on versions, depending on punch point size.

The QuickLock system also features dies made of exceptionally wear-resistant tool steel with optimized heat treatment for perfect balance of wear and toughness.

These QuickLock dies also have: double-cut die opening for improved accuracy; uniform clearance radii in the die corners for improved component edge quality; improved die strength with domed relief to evenly distribute punching forces.

They also have superior roundness and flatness for improved piece part quality and up to 0.059 (1.50 mm) grind life.

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.
