Bernardo Flat Grinding Machine BSG 60160 PLC

Bernardo BSG 60160 PLC Surface Grinder with 2-Axis DRO

The Bernardo BSG 60160 PLC surface grinder with ES-12 H 2-axis digital readout is designed for precision grinding operations on large and heavy workpieces. The 600 x 1600 mm table, equipped with hardened and ground guideways with Durcit-B coated counter-guideways, ensures rigidity, stability, and long service life. Longitudinal and cross movements are achieved via V-flat guideways, while the modern hydraulic system guarantees smooth feeds even under loads up to 1300 kg. The Siemens PLC control, with a touchscreen panel, allows for rapid programming of automated cycles: roughing, finishing, and automatic return to the home position. With a 350 mm grinding wheel, a 7.5 kW motor, and a massive cast iron structure, the BSG 60160 PLC is a reliable and high-performance machine, ideal for companies and workshops requiring top-level grinding.

Frequently asked questions

What grinding precision can be achieved with the Bernardo BSG 6 Surface Grinder?

Under optimal conditions, Bernardo surface grinders achieve dimensional tolerances of IT5–IT6 and 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 BSG 6 Surface Grinder model?

The PLC suffix indicates that the grinder is equipped with programmable PLC control — it allows for 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 grinding wheel should be used for steel vs cast iron vs aluminum?

Steel: Alumina (Al₂O₃) grinding wheel A46K–A60K. Cast iron: Silicon carbide (SiC) grinding wheel C46K–C60K. Aluminum: Silicon carbide grinding 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 BSG 6 Surface Grinder require an integrated coolant?

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.

Are spare parts and grinding wheels available?

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