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, opposite 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 processing. Replace both simultaneously to even out the 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 control for intensive use. Regular replacement of original blades maintains cutting precision and quality.
Why a specific set for stainless steel?
Stainless steel knives are made of higher quality hardened steel, with specific heat treatment to withstand the high stresses of stainless steel cutting.
Stainless steel is 1.5-2 times more resistant to cutting than mild steel. Standard knives would wear out quickly. Stainless steel-rated knives have a hardness of 60-65 HRC and resist heating and deformation.
How do you know when they need to be replaced?
Signs include burr cutting, sheet edge deformation, altered noise, excessive effort during activation.
For occasional use (hobby, maintenance) knives last many years. For daily workshop use, revision is recommended every 6-12 months and preventive replacement every 18-24 months.
How is manual replacement performed?
For manual shears and notchers, replacement can be performed by the operator: removal of fastening screws, disassembly of the old knife, assembly of the new one with the correct tightening torque.
Important: respect the tightening torque indicated in the manual (typically 30-60 Nm). Insufficient tightening causes the knife to move, excessive tightening risks cracking it. Krollit provides technical documentation.
