Frequently asked questions
What does the lower blade of the HA 200 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 processing. Replace both simultaneously to equalize cutting pressure.
What does the HA 200 work with?
It is a manual angle notching machine for angles up to 200 x 200 mm. Manual lever operation with hardened steel blades.
Suitable for metal fabricators and blacksmiths. Regular replacement of 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.
The 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 is recommended every 6 months and preventive replacement every 12-18 months.
Wear indicators: burr cutting, sheet edge deformation, altered cutting noise, excessive effort during operation. Keep a spare set in stock.
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: 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.
