Notching Machines for Lamination
The notching machine are designed for applications in the electric machine industry for the stator and rotor laminations by notching single or multiple slot patterns. Ideal for the production of laminations in small lots (including prototypes), or large diameter laminations (for example, wind turbine generators). In these cases, they can replace mechanical presses for progressive or compound blanking. The notching machine can cover a large range of diameters and working cycles by adjusting the spindle/slide unit on the fixed frame, adapting it to the size of the blank to be machined.
Galbiati Group has designed and manufactures an innovative notching machine for blanking laminations with the spindle directly driven by the crankshaft. This provides high precision over time as there is no backlash induced by transmission gears. The fixed spindle center guarantees maximum efficiency thanks to the automation of loading and unloading operations, regardless of lamination diameter .
The machine is controlled by a Siemens Sinumeric 4-axes Numerical Control which provides maximum flexibility for machining cycle management resulting in higher productivity. The CNC can set and control the mechanical release of punch penetration from 2 to 4 mm.
The notching machine’s control panel has a simple, user-friendly interface and allows the user to set a series of parameters for quick custom machining. The following parameters can be set on the control panel:
* Notching speed
* Number of slots
* Slide position with respect to the centre of the indexing spindle
* Angular position for cycle start
* Blank centering adjustment
* Angular compensation to offset blank thickness variations
* Speed reduction at end of the notching cycle
* Machining cycles can be stored and recalled
* Activation of special machining cycles, such as conical or skewed stacks, enlarged slots, etc .
* Alarms and diagnostics
Galbiati notching machines are equipped with advanced alarm and diagnostic systems that are extremely user-friendly. Generally speaking notching machines are preferred when the production volumes of laminations do not justify the investment for a mechanical press.
