Frequently Asked Questions
What does the top blade of the HA 200 do?
The top blade is the movable part that descends onto the sheet metal to produce the cut, opposed to the fixed bottom blade.
It is the blade subject to greater wear due to repeated movement. For series production, it should be monitored frequently: anomalous sparks and cutting with burrs are the first signs of necessary sharpening.
What does the HA 200 process?
It is a manual angle notcher for angles up to 200 x 200 mm. Manual lever operation with hardened steel blades.
Suitable for metal structural work and locksmith workshops. Regular replacement of the knives maintains cutting quality on angle profiles.
Are the blades made of hardened steel?
Yes, Bernardo blades are made of high-quality hardened and ground steel.
Heat treatment increases surface hardness (typically 58-62 HRC) and resistance to deformation, even when cutting alloy steels or thick aluminum.
When to replace knives for intensive use?
For continuous use (8 hours/day), a review every 6 months and preventive replacement every 12-18 months is recommended.
Wear indicators: cutting with burrs, deformation of the sheet edge, altered noise during cutting, excessive effort during operation. Keep a spare set in stock.
How is the replacement carried out manually?
For manual shears and notchers, replacement can be performed by the operator: remove fastening screws, disassemble the old knife, assemble the new one with the correct tightening torque.
Important: observe 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.
