New press brakes series with high tonnage
The development of electric press brakes with spindle drive continues. CoastOne Oy (Finland) has introduced the first machines of the new Bull series.
Two versions are now available:
Bull12 are 100 Ton press brakes with a bend length of 1300 millimeters, and Bull15 are 150 Ton press brakes with a bend length of 1600 millimeters.
Bull series is a solution when high tonnage is needed with superior accuracy.
High precision O-frame with Taylor made ball screws makes Bull-series superior solution for high accuracy bending works. Bull is an optimal solution with a small footprint and high tonnage. Bull is an optimal solution with a small footprint and high tonnage.

Compare Coast One Electric Press Brakes to Hydraulic Press Brakes
 |  | |
| CoastOne Electric Press Brakes | Traditional Hydraulic Press Brakes | |
| Motor | Direct-drive system with servo-electric motors and ball screw(s) | Hydraulic motor, pump and fluids |
| Efficiency | The Average power consumption of CoastOne electric press brakes is 1-3 kW. It consumes less electricity, conserves energy -only use energy when in motion. Est. 20 to 30 percent more energy efficient | Traditional hydraulic press brakes run hydraulic pumps and heating fluids all day. These can be less efficient and expensive to run and maintain. |
| Accuracy | CoastOne Offers an extreme accuracy of 0.000079 inches! Also known as 1 micron! | Accuracy and repeatability can only reach up to 0.0004" |
| Speed | CoastOne electric press brakes have a faster output with a direct positioning system. Machines determine position using rotary encoders on servo motors. No hydraulic fluids. Therefore, no extra time to “decelerate” hydraulic ram to position | Fast approach speed, but slower ram accelerations and "decelerations" due to use of hydraulic fluid |
| Noise pollution | Electric press brakes are silent when not in motion. While in motion, the only sound heard is the servo-motor(s) spinning ball screw(s) | Hydraulic press brakes are constantly running hydraulic pumps while the machine is on. |
| Green | Often much lower energy consumption. Fully- electric press brake means there is no oil. CoastOne press brake runs off only 24V when not in motion. | Often hydraulic press brakes use more energy than fully- electric press brakes due to the hydraulic pumps constantly running when the machines are turned on. Excess oil from hydraulic systems needs disposal. Oil needs to be added/changed |
| Safety | Ergonomics have been incorporated into the design process to keep your operators safe and comfortable to help maximize their productivity. CoastOne press brakes all come standard with a fully-integrated LazerSafe system to protect the operator. Ram will not “drift” with a direct-drive press brake and ram safety spring. | Hydraulic press brakes can act differently, depending on the time of day/temperature of the oil. It is very important to make sure the machine comes with safety systems. Ram must always be "blocked" when not in use, due to the possibility of ram "drift." |
| Save Money | CoastOne electric press brakes typically consume less energy. The lack of hydraulic oil eliminates expensive oil changes, spare parts, valves and maintenance expenses common to hydraulic press brakes. | Hydraulic press brakes need oil and filter changes and inspections. They can have seal and line leaks, require oil disposal and have more frequent machine shut-downs. Also, due to oil viscosity fluctuations, you are more likely to create more scrap on hydraulic press brakes than on a direct-drive press brake such as CoastOne machines. The angle you get at the start of the day will be the same angle when you shut the machine down for the night. |
