LP-700 Heavy-Duty Punching Machine 700 mm

Intended for all types of book and calendar punching production

Heavy-duty professional punch machine, suitable for large range of products. Maximum punching thickness per stroke for standard punching dies is 4,5 mm but custom-made enforced dies can punch paper packs up to 8 mm thick. LP-700 is similar in design to LP-500 and shows the same advantages however it has the extended width of punching for one stroke which equals to 720 mm. The LP-700 is actuated by gear-motor drive with the frequency converter allowing to control acceleration phase, working phase and shutdown phase independently what has a knock-on effect on the great precision in the breakpoint adjustment. Special mentions should be made of punching dies. Split three-part dies with thumb cut allow book block punching up to 680 mm in width as well as calendar punching up to 720 mm without the need to invest in a second die. Guides of all punching dies are made of bronze and also punch pins are made of superior high-alloy steel whereby dies durability increases threefold in comparison with steel guides and punch pins can be sharpened multiple times. Besides that dies configuration allows the quick cancellation of any punching knife, adjusting perforation depth and distance from the punching edge. Special tear-off perforation and scoring dies are also available providing range of options for using LP-700 beyond calendars producing season. The scoring die is designed with a possibility of score width adjusting up to 5.5 mm and variable geometry of scoring plates what is good for work materials of various thickness and base weight. Our engineers can design and produce punching dies with any bespoke punch patterns (e.g. rectangular, triangular, and elliptical).
