Frequently Asked Questions
Which machine are these knives for?
They are original Bernardo spare parts for the PTS 650, a small motorized shear.
The PTS 650 has a sheet metal capacity of up to 1.25 mm (400 N/mm²), a length of 650 mm, and is intended for craft workshops and maintenance departments. Foot pedal control, 0.75 kW motor at 400 V, micrometer stop.
The PTS 650 is motorized: does it have double-edged blades?
Yes, Bernardo motorized shears MTA/MTM/MTE/MTR mount double-edged upper and lower blades made of hardened steel to maximize operational life.
When one edge wears out, the blade can be rotated to use the opposite edge, effectively doubling its lifespan 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 for production, replacement depends on the cutting cycles: typically every 200,000-500,000 strokes on mild steel.
Indicators of wear: increased burr, deformation of the sheet metal edge, altered noise, decreased 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: power disconnection, removal of guards, disassembly of knives with torque wrenches, calibration of blade clearance.
Blade clearance must be set according to the sheet metal thickness (typically 5-8% of the thickness). Incorrect calibration produces burrs or jams the machine. Krollit provides technical support.
