Frequently Asked Questions
Which machine are these blades for?
They are original Bernardo spare parts for the MTM 1250, a motorized guillotine shear.
The MTM 1250 has sheet metal capacity up to 4 mm, length 1250 mm, and is intended for professional workshops. Similar to MTA models with greater thickness capacity.
The MTM 1250 is motorized: does it have double-edged blades?
Yes, Bernardo MTA/MTM/MTE/MTR motorized shears feature double-edged upper and lower blades made of hardened steel to maximize operational life.
When one cutting edge wears out, the blade can be rotated to use the opposite edge, effectively doubling its service life before complete replacement.
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.
How often should blades be replaced on a motorized shear?
On motorized shears used for production, replacement depends on cutting cycles: typically every 200,000-500,000 strokes on mild steel.
Wear indicators: increased burr, sheet edge deformation, altered noise, drop in dimensional precision. For MTE/MTR with double-edged blades, rotate before replacing.
How is replacement performed on a motorized shear?
Replacement requires a qualified technician: disconnect power, remove guards, disassemble knives with torque wrenches, calibrate blade gap.
The blade gap (clearance) must be set according to sheet metal thickness (typically 5-8% of thickness). Incorrect calibration results in burrs or machine blockage. Krollit provides technical support.
