LVD Strippit has introduced the M-series of midrange, 20-metric-ton CNC turret punch presses featuring a 51 percent larger turret capacity than previous models. Equipped with the company's energy reduction system (ERS), the punch presses consume up to 30 percent less electrical power than comparable machines, according to the manufacturer.
The 47 turret stations include three 3.5-in. autoindex stations and four 2-in. stations. Each station accepts shaped punches and dies and can be enhanced with the addition of indexable multitools to expand turret capacity and flexibility. Quick-change die holders help minimize tool changeover time.
Bidirectional turret rotation automatically selects the shortest possible route to the next punching station for fast station-to-station positioning. The machines reach axis speeds of up to 380 HPM on 1-in. centers and up to 900 HPM on 0.04-in. centers. They handle workpieces up to 49.21 by 98.4 in., with larger sheets processed using clamp repositioning. Thicknesses up to 0.250 in. are accommodated.
The Smart Clamp™ feature automatically determines exact clamp locations to help reduce setup time and ensure work clamp protection. The machines also feature a 0.984-in. feed clearance between the upper and lower turret, allowing for the production of higher forms such as lances, louvers, embossments, and card guides.
