Bernardo Surface Grinder BSG 2040 MC

Bernardo BSG 2040 MC Surface Grinder

The Bernardo BSG 2040 MC Surface Grinder is a compact and precise tangential grinding machine, ideal for grinding small surfaces and quick machining operations. Thanks to its professional quality spindle bearings, it ensures smooth and vibration-free operation. The hardened and ground guideways ensure precise movements of the longitudinal table and the double V-shaped cross table. The high-strength grey cast iron structure guarantees stability and durability. Included are a 200 x 400 mm permanent magnetic chuck, a centralized lubrication system, and a 55-litre coolant device, ensuring safe and continuous operations. The machine comes complete with a 2-axis digital readout ES-12 H, LED light, protective covers, and balancing accessories. With compact dimensions and a weight of 850 kg, it represents a reliable and efficient solution for mechanical workshops and precision departments.

Frequently asked questions

What is the achievable grinding precision with the Bernardo BSG 2 surface grinder?

Bernardo surface grinders achieve dimensional tolerances of IT5–IT6 and surface 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 in the Bernardo BSG 2 surface grinder model mean?

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 identical batches of parts.

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

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

Does the Bernardo BSG 2 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 prevent surface burns that alter the material's structure. Always use the appropriate type of coolant for the material being processed.
