Machines and Devices
Core Cutting Lines
Our core cutting lines and stacking systems are made to meet your specific requirements. From standardized lines up to customized solutions, we understand your requirements and provide the best suitable solution. Innovative solutions guarantee highest flexibility and output.
Depending on the expected machine output and core design we do offer 5 different type of cutting lines. While most machines are designed to produce 45° step lap (mitre) cores we also offer highly efficient machines for 90° (but lap) core design or shunt core production lines. The cutting lines can be combined with different stacking systems.
Stacking Systems
The type of stacking system really makes the difference. While the cutting line is responsible for the production of highly accurate sheets within smallest possible tolerances, the stacking system defines the necessary work to assemble a core afterwards. A simple stacking solution usually requires more manual handling for the manual stacking process. The better the stacking accuracy the faster the final E-stacking process will be. Tuboly-Astronic does offer solutions for the entire range from simple roof stacking up to full automated log stacking or complete automated E-stacking of the core.
The type of stacking solution does also have impact on the overall machine performance. Let us know your core design and expected production output and we can do a calculation in order to propose the most economic overall solution for your specific demand.
Core Manufacturing & Core Cutting Lines
These sophisticated, high-quality core cutting lines – combined with an innovative stacking solution – play a key role in efficient core production.
Compact machines for 250/450/650 mm width
The CCC line is our economical and cost-efficient solution for the production of standard core shapes. The machines can be combined with simple or sophisticated stacking systems and are therefore perfectly suited for core production start-ups or when existing capacities need to be extended.
Modular machines for 450/650/850/1000 mm width
The CCM line can be used for almost all core shapes. The modular design guarantees the highest possible flexibility and thus secures the value of the investment for many years. Additional modules can also be added later.
High speed machine for 350 mm width
The CCH lines are designed for highest possible output quantities. The machine has been optimized for the trimming of two or three limbed cores. Four hole punching tools, a V-punching tool and a cutter tool are equipped with an automatic positioning system for stop point reduction.
90° cutting machines 250 / 350 mm width
The CCR machines are made for an efficient production of 90° cut core sheets for reactor, choke or but lap cores.
Shunt reactor core machine for 500 mm width
The CCS line is particularly suited for radially stacked sheets shaping a round choke core. Complete choke cores can be produced if the line is combined with a stacking robot. Complementary equipment allows the additional cutting of 90° sheets used in choke cores.
Stacking Systems
Degree of automation, flexibility, stacking precision and output quantities – these are the parameters essential for the choice of a stacking system.
Besides our standard concepts, we also design customer-tailored solutions.

Distribution transformer cores (250/350/450 mm)
Conveyor stacking system
The economical CSB stacking system places the cut sheets in multiple stacking bins. This concept ensures safe unloading of the cut sheets without having to interrupt production.
Versatile and efficient two level stacking system
The CSC2 concept is highly efficient and multifunctional. Stacking on two levels ensures large output quantities as well as high stacking accuracy. The controlled timing belts allow the simultaneous production on two levels of multiple stacks placed side by side or behind each other.
5 stacking positions inline with stacking pins
The CSD(M)5 stacking system is the perfect solution when finished laminations need to be stacked. The three limbs and two yokes are stacked in consecutive order and placed side by side at extremely high speeds. The system allows 5-pin stacking positions for the production of multiple stacks next to or behind each other. Our premium solution comes with a height monitoring and compensation system.
Inline E-Stacking systems for open or closed top yoke
The CSEC stacking system automatically produces precisely stacked two and three limbed cores. Stacker and stack production are integrated in the core cutting line. This concept provides the highest degree of automation.
Our solution allows placement of top and bottom core yoke.
Robot E-stacking system for open or closed top yoke
The robot E-stacking solution was developed to produce small distribution cores in an efficient and automated way at investment costs which guarantee a fast return on your investment. The robot E-stacking system is installed inline to our 250 mm cutting line. The cut sheets are pre-stacked in a pre-stacking station on two levels. The robot with its gripper is than stacking the complete book on stacking pins on a stacking table with quick exchange feature for shortest possible set-up time. All our E-stackers can stack standard or asymmetric yokes.
The system convinces by its performance and flexibility in arrangement of the different modules. It can be a one robot solution, extended by an additional log stacker or a two-robot solution.
Power transformer cores (650/850/1000 mm)
Pick and place stacking system
Our CSP1/2 is a simple but flexible system for the production of power transformer or distribution cores. Due to its timing belt system it is possible to stack multiple logs behind each other. The system is available as a one level or two level version with two or four grippers.
Versatile and efficient two level stacking system
Our CSA2 stacker stacks the cores in a most versatile, efficient and space-saving manner. The sheets are stacked on two levels ensuring large output quantities as well as high stacking precision. Our solution is tailored to the production of large power transformers. The precision-controlled timing belts enable the production of multiple stacks placed next to each other on two levels.
Versatile and efficient stacking system with two stations inline
The CSI2 stacking system consists of two stations installed in tandem. This versatile and efficient solution guarantees high stacking precision and large output quantities. Our solution is tailored to the production of large power transformers. The precisely controlled timing belts allow the consecutive production of multiple stacks per level.
Inline E-Stacking systems for open or closed top yoke
The CSE(C) E-stacking system is designed for the automatic production of two and three limbed cores and is installed inline to the core cutting line. This concept provides the highest degree of automation unmatched by other core stacking lines. All our E-stackers can stack standard or asymmetric yokes.
With our CSE type it is possible to stack the E-core with closed bottom yoke while the top yoke is placed separately.
With our CSEC type it is possible to stack the E-core with closed bottom and top yoke or the top yoke placed separately.
