Description
Bernardo BSG 80160 PLC Surface Grinder with 2-axis DRO
The Bernardo BSG 80160 PLC surface grinder with ES-12 H 2-axis digital readout is a professional machine for the precision grinding of large workpieces up to 2000 kg. The 810 x 1600 mm table with hardened and ground guideways and Durcit-B counter-guideways ensures rigidity and smooth movement. Longitudinal and transverse movements occur via V-flat guides, while the advanced hydraulic system guarantees smooth translations even under heavy loads. The Siemens PLC control with touchscreen allows for programming automated grinding cycles, including roughing, finishing, and automatic return to the home position. The 500 mm grinding wheel, the powerful 18.5 kW motor, and the massive structure with an annealed base and thick reinforcements make the BSG 80160 PLC ideal for heavy industrial applications and high-precision machining.

Frequently Asked Questions
What grinding precision can be achieved with the Bernardo BSG 8 surface grinder?
Bernardo surface grinders achieve dimensional tolerances of IT5–IT6 and roughness 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 "PLC" suffix in the Bernardo BSG 8 surface grinder model mean?
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) without manual intervention during the cycle. Compared to the manual version, it reduces cycle times and produces more repeatable results on series of identical parts.
Which grinding wheel to use for steel vs. cast iron vs. aluminum?
Steel: A46K–A60K aluminum oxide (Al₂O₃) wheel. Cast iron: C46K–C60K silicon carbide (SiC) wheel. Aluminum: C46J–C60J silicon carbide wheel with abundant lubrication. Do not mix different materials on the same wheel — metal residues contaminate the ground surface.
Does the Bernardo BSG 8 surface grinder require 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 business days shipping. Customer support available in Italian.
