Bernardo Flat Grinder FSM 3060

Bernardo FSM 3060 Surface Grinder

The Bernardo FSM 3060 is a professional surface grinder designed for precise grinding of flat surfaces, ideal for mechanical workshops, production departments, and precision machining. The machine is built with a flat V-longitudinal guide and a double V-transverse guide, ensuring smooth movements and constant stability. The spindle is supported by preload axial and radial bearings, free of play, to guarantee accuracy and reliability. It features an advanced hydraulic system with a heat exchanger, which reduces vibrations and thermal loads, keeping the table smooth even under load. Standard features include a 2-axis digital display, a 300 x 600 mm permanent magnetic chuck, a centralized lubrication system, and numerous accessories. With a Ø 300 mm grinding wheel driven by a 4.0 kW (1440 rpm) motor, it offers high performance and great stability thanks to its 1330 kg weight.

Frequently Asked Questions

What is the achievable grinding precision with the Bernardo FSM 3 Surface Grinder?

Bernardo surface grinders achieve dimensional tolerances of IT5–IT6 and roughness Ra 0.4–0.8 µm under optimal conditions. The actual precision depends on the condition of the grinding wheel (periodic dressing), the workpiece material, the coolant, and the operator's experience.

What does the "PLC" suffix mean in the Bernardo FSM 3 Surface Grinder model?

The PLC suffix indicates that the grinder is equipped with a programmable PLC control — it allows setting automatic grinding cycles (number of passes, depth per pass, feed rate) without manual intervention during the cycle. Compared to the manual version, it reduces cycle times and produces more repeatable results on batches of identical parts.

Which grinding wheel to use for steel vs cast iron vs aluminum?

Steel: Corundum (Al₂O₃) A46K–A60K grinding wheel. Cast iron: Silicon carbide (SiC) C46K–C60K grinding wheel. Aluminum: Silicon carbide C46J–C60J grinding wheel with abundant lubrication. Do not mix different materials on the same grinding wheel — metal residues contaminate the ground surface.

Does the Bernardo FSM 3 Surface Grinder require integrated coolant?

BSG and FSM surface grinders are equipped with an integrated cooling system — essential for precision grinding of hardened steel to avoid surface burns that alter the material's structure. Always use the appropriate type of coolant for the material being processed.

Are spare parts and grinding wheels available?

Original spare parts available with 3–5 business days shipping. Customer support available in Italian.
