Guillotine shear is a remarkable cut used in many of the buildings we are in today and in steel constructions. It is also called “Double-sided” because of its double blade for guillotine cutting, which is a widely used cutting method. Manual guillotine cutting in the past has emerged as a successful equipment for the creation of a standard and efficient product by being included in the computerized working system, with the CNC technology taking its place in production. In guillotine cutting, two moving knives cut the pieces placed between them and thus the process is carried out. Thanks to the cutting gap adjustment, blade adjustment and back gauge adjustment in guillotine shear cutting, the operator has the chance to prepare the desired product without error.
