The LVD/Strippit Global 20 turret punch press shown for the first time at a European exhibition provides a combination of high productivity, large sheet capacity and an increased turret size with additional auto-index stations. The Global 20 will be demonstrated with full automatic sheet loading and unloading, part sorting and picking. Based on a bridge frame construction to maintain high orders of stiffness, the Global 20, now available from LVD (UK) of Marlow, delivers axis positioning speeds of 110 m/min.

It includes the flexibility of a 30-station turret with less than one second station to station index time and a choice of three or four auto-index positions.

The machine uses GE Fanuc 180i PC-based control and drives package.

The Global 20's modern design creates an ideal punching machine platform to process work pieces up to 2500 mm by 1250 mm and 6mm thickness without repositioning to an accuracy of +0.10mm and repeatability of +0.05mm.

A servo-driven hydraulic ram is fully programmable, has a 200kN punching force, is capable of producing 800 strokes/min and provides high flexibility for punching and forming applications.

The incorporation of Strippit's patented Smart Stroke, maximises productivity without operator or programmer intervention.

With Smart Stroke, the punching cycle is optimised through automatic determination of the hover height of the ram based on material thickness and distance between holes.

Turret configurations for thin or thick style are available, each with replaceable hardened steel bush guides to reduce wear.

Three 88.9mm Auto-Index stations are included as standard with the option of a fourth for higher tool capacity.

Tooling flexibility can be further enhanced with inclusion of three, eight or 30 station Multi-Tools.

In addition, indexable Multi-Tools can be used to expand the number of auto-indexable tools.

Choice of brush, ball transfer or 50:50 ball/brush tables are available giving improved sheet support and quiet operation.

The three programmable work clamps, included as standard, can be individually programmed to a position on the X-carriage and relocated to a new position within the part program.

This feature virtually eliminates 'no punch' zones.

A programmable work chute of 450mm by 500mm is included.
The PC-based GE-Fanuc 180i control considerably reduces set up times and being Windows based provides powerful features such as diagnostics, increased program storage and networking.
