A famous institute, years of tests on the field and advanced technology are the basis of its high quality and reliability. Thanking to their unique features, the Series DWS machines are considered as a landmark in their field of quarrying. The electronic feed control system, which guarantees constant and uniform motion, has been studied to increase diamond wire efficiency A central rack ,maintenance free ,is positioned on the rail: this system allows to avoid mud deposit and slip risk. The special feed system, gears on steel cylinders, permits a correct positioning of the machine even on sleepslopes. The aluminum flywheel, directly connected with the motor to minimize the powerlacks, can rotate on 360 degree which make any kind of cut. The lateral translation is 30 cm per side. The same system allows making two vertical cuts at a max distance of 160cm,without moving the machine. The horizontal cut can be made without leaving any steps.
