Frequently Asked Questions
What does the lower blade of the AK 150 P do?
The lower blade is fixed to the workbench and supports the sheet metal during cutting, opposing the movable upper blade.
Wear is symmetrical with the upper blade, but the lower blade tends to deform under the weight of the sheet metal during intensive work. Replace both simultaneously to equalize cutting pressure.
What does the AK 150 P do?
It is a pneumatic notching machine with a capacity of 150 x 150 mm at 90°, sheet metal up to 2 mm (400 N/mm²), suitable for professional workshops with continuous use.
2.2 T pneumatic cylinder, foot pedal control for intensive use. Regular replacement of original blades maintains cutting precision and quality.
Are the blades made of hardened steel?
Yes, Bernardo blades are made of high-quality hardened and ground steel.
The heat treatment increases surface hardness (typically 58-62 HRC) and resistance to deformation, even when cutting alloy steels or thick aluminum.
How do you know when they need to be replaced?
Signs include burred cuts, deformation of the sheet edge, altered noise, excessive operating effort.
For occasional use (hobby, maintenance) the knives last many years. For daily workshop use, revision every 6-12 months and preventive replacement every 18-24 months is recommended.
How is the replacement performed manually?
For manual shears and notching machines, replacement can be performed by the operator: removal of fixing screws, disassembly of the old knife, assembly of the new one with the correct tightening torque.
Important: observe the tightening torque specified in the manual (typically 30-60 Nm). Insufficient tightening causes the knife to move, excessive tightening risks cracking it. Krollit provides technical documentation.
