Due to the constantly changing demands of customers, the pressure to manufacture short batches flexibly and quickly has grown. As a result, new innovative solutions are needed to improve productivity and flexibility.
The emergence of servo-electric technology has improved the speed and accuracy of machines, while dramatically reducing energy consumption and operation costs. Increased punching speeds, combined with higher axis accelerations and speeds, have increased the productivity of the Prima Power punch/shear units by approximately 25% every five years.
The latest Prima Power Shear Brilliance cell has become compact and easier to install, and its improved performance has made it significantly more productive. Other factors that have improved its productivity include automation in material handling, increased tool capacity, and the development of the control system and actuators. It is also possible to attach the cell to a manufacturing line
Shear Brilliance
Finn-Power Oy introduced the first Shear Brilliance cell utilising linear servo technology in 2000. Even at that time, the cell had an exceptional performance and technical design.
The latest Prima Power Shear Brilliance cell has become compact and easier to install, and its improved performance has made it significantly more productive. Other factors that have improved its productivity include automation in material handling, increased tool capacity, and the development of the control system and actuators. It is also possible to attach the cell to a manufacturing line.
Improved performance with a carbon-fiber structure
More efficient use of the work area provides increased benefits, such as processing longer sheets with the same setting. The work area consists of a carbon-fiber coordinate table, nearly eight meters long, that positions the sheet.
With carbon fiber the weight of the structure was reduced by approximately 70%. This lightness has a significant effect on the performance, energy-efficiency, actuators, and surrounding structure of the machine
Carbon fiber is a material that enables a light but rigid structure for an axis movement that is longer than before. A combi machine, which is able to punch and shear long sheets in a combined working area without repositioning and has a larger working area and improved performance, brings benefits that are evident both in productivity and quality.
The capability to process sheets of more than three metres in length, a stroke mechanism of 1,300 strokes per minute, and a structural acceleration of 2 g are performances that cannot be achieved with steel structures in machines of this size category. The solution was carbon fiber that has been used in the manufacturing of the Shear Brilliance cell’s coordinate table.
With a carbon-fiber-reinforced composite structure, it was possible to reduce the mass of the coordinate table, which moves the sheet during processing, from a 700 kg steel structure to a 225 kg carbon-fiber structure. In other words, the weight of the structure was reduced by approximately 70%. This lightness has a significant effect on the performance, energy-efficiency, actuators, and surrounding structure of the machine.
Energy efficiency and ergonomics
The lightness of the structure also reduces energy consumption, which is in line with the Prima Power Green Means® social responsibility philosophy. The power consumption is only 8 kW, the smallest in the world in this machine category.
With the latest programs, the cell is easy and logical to use. Programming is carried out easily with 3D CAD models.
