PRODUCT REVIEWS
Greater control of stamping process
As an exhibition premiere, Bruderer presented its new-generation B3 control for BSTA automatic stamping presses at Blechexpo 2025 in Stuttgart, Germany, this October. The manufacturer has integrated numerous new functions into it.
“ The process control has been improved and the operation simplified, in line with current user-centric standards. The futureproofed control system also enables seamless connection of a wide range of peripheral devices, including those from third-party suppliers, and supports open data exchange with machines, production control systems and IIoT applications via OPC-UA interfaces,” confirmed the Swiss stamping specialist.
According to Bruderer, this makes stamping processes easier, faster and more reliable to control.
Fully integrated solution
The B3 control system has been newly designed from scratch. It incorporates the experience gained from more than 5,000 installed B and B2 control systems.
At Blechexpo 2025, it was shown integrated into a stamping line consisting of a BSTA stamping press, a BSV servo feed unit and a new BSP lamination stacking control. The B3 control system’ s operation panel allows all functions to be operated and controlled centrally, including those of connected peripheral devices.
“ The 21-inch touchscreen with tile view has a user interface which can be individually configured to suit each user and allows direct access to all functions of the stamping press and peripherals. Thanks to its modular design, the B3 control is simple to operate and yet scalable, which means that it can be set up for simple stamping processes as well as more complex operations. Whether it is rotor-stator production( with the help of the new BSP lamination stacking control) or the complete production of connectors, the B3 is ideally suited to a wide range of functions and requirements,” confirmed Bruderer.
The B3 control system features a rolebased access system with predefined user rights, which helps to reduce operating errors. Stamping tool, press force and position are controlled in the main operating window. Additional envelope monitoring displays changes in individual modules in real time, enabling stamping faults to be detected more quickly.

“ For the first time, the monitoring of stamping tools, slides and indexing stations can be automatically programmed at the touch of a button using an intelligent parameterisation system. Previously, this had to be programmed manually. The B3 control system will be available on new BSTA stamping presses from 2026. Existing Bruderer automatic stamping presses can be upgraded from mid-2026. The tried-andtested B2 control system will continue to be supported,” added Bruderer.
BSP lamination stacking control

Bruderer also presented its BSP lamination stacking control for rotor-stator production at Blechexpo 2025 in Stuttgart.
“ The BSP control system enables short set-up times, high process reliability and flexible configurations. Even complex stacking strategies can be implemented easily thanks to its intuitive operation. Developed in close cooperation with customers, the control system has been tailored to the requirements of rotor-stator production and has been extensively tested in practice,” it told ISMR.
“ The BSP lamination stacking control is a highly productive solution for the growing market of lamination stacking for electric motors and transformers and is integrated fully with other products made by us,” it added.
The lamination stacking control is based on the technology of the B3 machine control and is operated via a 21-inch touchscreen. A freely configurable start screen with tile layout, role-based access rights and clear control logic, as well as programming of sheet metal shapes for later reuse, make it intuitive and easy to use. Up to eight parallel programme channels enable the implementation of a wide range of lamination stacking strategies. Diagnostic and statistical functions support process analysis, while exportable parameters facilitate use in IIoT environments.
Key benefits of the BSP system include components“ that configure themselves at the touch of a button for rapid and reliable set-up.” Up to six freely programmable indexing stations can be set up via plug-and-play; motors are automatically detected, parameterised and monitored. The‘ automatic ramp time’ function adapts movements to the stroke speed, shortens tool set-up times and reduces tool wear.
“ The slide control is set up automatically, eliminating the need for manual adjustments and minimising sources of error. The maximum of 32 slides can be arranged and connected with short connection cables. They each have two inputs and outputs that calibrate themselves automatically and correct themselves if necessary. Tool monitoring for up to 32 channels is also taught in automatically,” explained Bruderer.
The BSP offers control options for indexing stations, slides and stamping tools, as well as position monitoring for up to eight channels with envelope monitoring and limit value consideration. A patented strip thickness measurement system with integrated stack height adjustment is featured.
“ The strip thickness measurement system, which operates inline in the BSV feed, precisely detects fluctuations in material thickness with an average accuracy of ± 0.01mm and compensates for them automatically. In addition, the stack height adjustment ensures that the end products maintain a consistent height, regardless of material tolerances,” said Bruderer. n
