Bernardo Surface Grinding Machine FSM 2550 AHD

Bernardo FSM 2550 AHD Surface Grinder

The Bernardo FSM 2550 AHD is a state-of-the-art surface grinder, designed for precise and automated grinding of flat surfaces. Equipped with automatic vertical feed with a servo motor, it offers digital adjustments for infeed, dressing, and lift-off at the end of the program, enhancing efficiency and reducing processing times. The highly stable cast iron structure, combined with an advanced hydraulic system, ensures smooth and vibration-free movements even under heavy loads. The longitudinal and transverse tables are adjustable via limit switches, and workpieces are clamped on a 250 x 500 mm electric magnetic chuck. Standard features include a 2-axis digital readout, touchscreen control, centralized lubrication, and professional accessories. With a Ø 200 mm grinding wheel powered by a 1.5 kW motor and a weight of 1100 kg, it represents an ideal solution for mechanical workshops and precision departments.

Frequently Asked Questions

What grinding precision can be achieved with the Bernardo FSM 2 surface grinder?

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

What does the "PLC" suffix mean in the Bernardo FSM 2 surface grinder model?

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

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

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

Does the Bernardo FSM 2 surface grinder require an integrated coolant system?

BSG and FSM surface grinders are equipped with an integrated cooling system — essential for precision grinding of hardened steel to prevent 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 day shipping. Customer service available in Italian.
