Bernardo BSG 3060 PLC Surface Grinder
The Bernardo BSG 3060 PLC is a professional surface grinder (tangential grinder), designed for precision, stability, and automation in flat surface machining. Equipped with a Siemens PLC control with touchscreen, it allows for easy programming of grinding cycles and automatic setting of table movements. The 305 x 635 mm table, with a longitudinal travel of 765 mm and a transverse travel of 340 mm, supports workpieces up to 270 kg with a magnetic chuck. The digital servo-assisted vertical feed allows for precise adjustments from 0.005 to 0.05 mm. The Ø 350 mm grinding wheel with a 4.0 kW motor ensures powerful and consistent machining, while the advanced hydraulic system with a separate unit and heat exchanger reduces vibrations and thermal deformations. With a weight of 2375 kg, it represents a solid, reliable machine ideal for mechanical workshops and precision departments.

Frequently asked questions
What is the achievable grinding precision with the Bernardo BSG 3 surface grinder?
Bernardo surface grinders achieve dimensional tolerances of IT5–IT6 and surface roughness of Ra 0.4–0.8 µm under optimal conditions. Actual precision depends on the condition of the grinding wheel (periodic dressing), workpiece material, coolant, and operator experience.
What does the suffix "PLC" mean in the Bernardo BSG 3 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 on batches of identical parts.
Which abrasive 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 wheel—metal residues contaminate the ground surface.
Does the Bernardo BSG 3 surface grinder require integrated coolant?
The BSG and FSM surface grinders are equipped with an integrated cooling system—essential for precision grinding on hardened steel to prevent surface burns that alter the material's structure. Always use the appropriate type of coolant for the material being processed.
