Bollina slitting lines for electrical transformer industry are specifically designed to process grain-oriented (GO) and non-grain-oriented (NGO) silicon steels for transformers, electric motors and other high-efficiency applications.
Cutting quality is essential in this sector. Dimensional accuracy, burr control and recoiling quality directly affect the performance of the final product. Every line therefore incorporates dedicated solutions designed to ensure the highest quality standards.
Mechanical design and automation are developed entirely by Bollina, allowing each line to be customised to the customer’s specific production requirements.
Technology Designed for Maximum Quality
The lines use a pack assembly system with circular knives, rubber rings and high-precision calibrated spacers. The slitting shafts are machined to extremely tight tolerances to ensure perfect tooling alignment and consistent cutting quality, even at maximum production speeds.
The entire line is optimised to achieve:
• Minimal burr formation
• High dimensional accuracy
• Excellent cut-edge quality
• Precise, stable recoiling
• High productivity while maintaining the highest quality standards
