Notching machine refurbishment
Control and automation
Updating control systems enables more precise and efficient processes. The implementation of automation technologies can increase productivity and improve user-friendliness.
Material supply and removal
Improving material supply and removal systems can help to make the production process smoother and more efficient.
Quality control
The implementation of modern quality assurance systems, such as image processing technologies and special sensor technology, can monitor and ensure the quality of the stamped parts
Spare parts management
Updating obsolete components and switching to more modern electronic components in electrical engineering can play an important role in the modernisation of grooving presses. This is particularly important if the old components are no longer available or are difficult to procure. New electrical components are generally not only more efficient, but also available on the market for many years.
Sound insulation
Noise protection is an integral part of our die-cutting modernisation solutions. Our soundproofing booths can be flexibly configured as stand-alone systems or as part of a fully automated production line, allowing us to significantly minimise noise pollution.
// Application example
notching machine refurbishment
Comprehensive overhaul and modernisation of the existing NN20 grooving machine.
General project scope

Questions and answers
Normally, a tool change on a grooving press takes less than 10 minutes.
A grooving press produces rotor and stator laminations for electric motors and generators using the single grooving process.
The stamped metal sheets are assembled into packages and then wound or moulded and assembled into a motor or generator.
Slot punches are used to manufacture electrical laminations (stators and rotors) for electric motors.
A single groove is punched into a circular sheet using a punching tool.
The sheet is then fed through a feed device (dividing head) by one division – the punching process is repeated.
Depending on the pitch, between 30 and 100 punching operations are carried out per sheet until the finished sheet is produced. This takes place at a stroke rate of 600 to 1200 punching operations per minute.
The production of sheet metal using the single grooving process is considerably cheaper and more flexible compared to a mould with a complete cut.
As a rule, the grooving press is operated at 600 to 1200 strokes per minute. This depends on the size and complexity of the component.
We currently offer grooving punches in a range of 5 – 20 tonnes punching force.
Slot punching at the highest level and maximum precision and output. The patented design of the grooving press enables high rigidity and optimum conditions for good automation.
Thanks to the drive technology used, there are no more wearing parts on the grooving press.
We offer customised solutions for the mechanical and electrical modernisation of old grooving presses. In addition, existing grooving presses can be retrofitted with our automation concepts.
Depending on the size and degree of automation, the output of our systems is between four and ten sheets per minute.
It usually takes around 10 months from ordering to delivery of a grooving machine. We often have a demonstration machine in-house that is available at short notice.
The grooving machine has a modular design and is very easy to maintain, as the grooving machine no longer has any wearing parts.
Hagel Automation specialises in the design and construction of slotting machines and the entire automation process. Hagel Automation supplies efficient, modern and highly precise slotting machines.
The costs depend on the required punching force, the equipment and the degree of automation of the grooving press. We are able to prepare a quotation for any application at short notice.
Approx. 4000 to 7000 kg.
Production of electrical sheets for motors and generators for wind power, hydropower and drive technology.
A single groove is punched into a circular sheet using a punching tool.
The sheet is then fed through a feed device (dividing head) by one division – the punching process is repeated.
Depending on the pitch, between 30 and 100 punching operations are carried out per sheet until the finished sheet is produced. This takes place at a stroke rate of 600 to 1200 punching operations per minute.
Currently, sheet metal with a diameter of 35 mm to 1300 mm is processed on grooving machines. The current trend is towards larger diameters of up to 1800 mm.
