CNC turret punch press with automated load

A LVD (UK) product story
Edited by the Manufacturingtalk editorial team May 3, 2006

A high speed, high productivity 200kN CNC turret punch press features automated loading and a components pick and sort system.

Shown for the very first time in the UK LVD ntroduced its high speed, high productivity Global 20 1225, a 200kN CNC turret punch press, with Automated Load - Pick and Sort System at MACH 2006, Hall 4, stand 4665.

The Global 20 1225 is part of LVD's Global 20 series of high performance turret punch presses.

The machine combines high production technologies to address the fabricating requirements of job shops and O.E.M.s around the world.

Its unique contemporary design provides a rigid base for precision punching.

Key features include large sheet processing capability, a 30-station turret with large auto-index capacity, and state-of-the-art GE Fanuc CNC control.

The Global 1225 on display at MACH2006 will feature a Robot Automated Load and Pick-Sort system for fast, cost effective cut-part unloading.

The robotic system handles cut part dimensions up to 1000 x 2000 mm with an unload time of 12s/part.

The Global 1225 processes workpieces up to 2500 x 1250mm.

Working area capacity with one repositioning is 5000 x 1250mm.

The punch press has an advanced hydraulic press drive optimized for high-speed operation.

This high-speed hydraulic system delivers up to 400 hits/min on 25mm centers and is capable of producing at 1000 strokes/min in continuous nibbling mode.

The hydraulic ram also offers the flexibility of electronic adjustments and features that take advantage of the intuitive control interaction.

Users can apply custom settings or alterations to stroke elements such as depth offset, dwell and ram speed, to further maximize machine capabilities.

Fully programmable stroke profiles and the exclusive Smart Stroke feature also maximize punching performance and provide flexibility for punching and forming applications.

Smart Stroke maximizes the productivity of the Global 1225 without operator or programmer intervention.

Smart Stroke automatically optimizes the punch cycle by determining the hover height based on material thickness and distance between holes.

The Global 20 1225 features a 30-station turret with station-to-station tool change in less than 1s.

Replaceable, hardened steel guide bushings eliminate turret tool bore wear.

The turret punch press is available with up to four dia 88.9mm auto-index stations.

Three auto-index stations are standard with the machine.

Turret capacity can be further increased with the addition of three- or eight-station indexable Multi-Tools to expand the number of auto-indexable tools.

Full Wheel tool capabilities (cutting and forming) together with thread tapping also expand turret flexibility.

The Global 20 1225 is equipped with three programmable, relocatable work clamps, which can be programmed to a position on the X carriage and individually relocated to a new position within the part program.

This reduces or eliminates 'no punch' zones.

Clamps can be spread a full 2300mm, providing the greatest sheet support in the industry.

A large 500 x 450mm Programmable Drop Door adds to the machine's productivity.

This feature can be combined with an optional CNC controlled three-bin sort system to additionally enhance throughput.

The Global 20 1225 punch press provides 0.10mm finished part accuracy and 0.05mm finished part repeatability.

The large table can be equipped with a combination of brushes and roller balls or a full brush tabletop for superior sheet support and smooth, quiet, scratch-free operation.

A state-of-the-art, PC-based GE-Fanuc control speeds set-up and provides powerful features such as diagnostics, increased program storage capacity of up to one gigabyte, and networking capability.

An innovative user interface provides graphic tooling images to aid with selections, making entering tool information easier than ever before.

Operators interact with a single graphic screen.

No tool measurements or electronic adjustments are necessary for routine punching and forming.

Maximum Productivity with Robot Automated Loading and Pick-Sort Part Handling LVD's Automated Load and Pick-Sort system increases the efficiency and throughput of the Global turret punch press with automatic cut-part unloading.

The Pick-Sort system features four independent sheet holders that are lowered to securely hold or retract the sheet according to the shape of the cut part and its position on the sheet.

A sheet sensing device detects whether the part is separated from the sheet.

The system also is protected against collisions.

Two external independent vacuum cups are available to handle unloading of larger dimensioned cut parts.

These vacuum cups are automated and positioned when required.

The Pick-Sort system converts the Global punch press into a free-standing, lights-out production cell.

Machine and robot are integrated to maximize punch press productivity.
