Frequently Asked Questions
What does the upper blade of the HA 220 do?
The upper blade is the moving part that descends onto the sheet metal to produce the cut, as opposed to the fixed lower blade.
It is the blade subject to greater wear due to repeated movement. For series production, it must be monitored frequently: anomalous sparks and burred cuts are the first signs of needing sharpening.
What does the HA 220 work with?
It is a manual angle notcher for angles up to 220 x 220 mm. Greater working capacity for angles compared to the HA 200.
Suitable for metal structural work for series production. Regular knife replacement maintains cutting quality on angle profiles.
Why a specific set for stainless steel?
Stainless steel knives are made of superior quality hardened steel, with specific heat treatment to withstand the high stresses of cutting stainless steel.
Stainless steel is 1.5-2 times more resistant to cutting than mild steel. Standard knives would wear out quickly. Stainless-rated knives have a hardness of 60-65 HRC and resist heating and deformation.
When should knives be replaced for intensive use?
For continuous use (8 hours/day), a review every 6 months and preventive replacement every 12-18 months are recommended.
Wear indicators: burred cut, deformation of the sheet metal edge, altered noise during cutting, excessive effort during operation. Keep a spare set in stock.
How is the replacement performed manually?
For manual shears and notchers, 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 indicated in the manual (typically 30-60 Nm). Insufficient tightening causes the knife to move, excessive tightening risks cracking it. Krollit provides technical documentation.
