LEN 63C eccentric press

LEN 63C eccentric press was built in 1978 in Slovakia by Smeral Trnava. The machine is used for precision machining of workpieces such as punching, cutting and stamping. All these machining processes are performed with a high press force of 63 tonnes, which, combined with a rigid design, ensures the production of parts with high repeatability and excellent precision.

The flywheel speed and number of slider strokes are steplessly adjusted by an inverter installed in the control system. This solution makes it possible to precisely synchronise the machine with the sheet metal feeder and the decoiler. A second, factory-installed control system, on the other hand, allows the machine to maintain a constant press force at maximum reduction of speed. The machine has CE certification.

The LEN 63 C press on offer underwent an upgrade in 2023, during which a new electrical system with inverter was installed. It is possible to purchase the machine in three different variants:
– press alone
PRICE: 32 000 PLN (7500 EUR)
– press + PA sheet metal feeder (sheet metal width 120 mm, sheet metal thickness 2.5 mm)
PRICE: 40 500 PLN (9500 EUR)
– press + sheet metal feeder PA (sheet metal width 120 mm, sheet metal thickness 2.5 mm) + sheet metal decoiler 500 kg
PRICE: 42 600 PLN (10 000 EUR)
