Bernardo Surface Grinder BSG 60220 PLC

Bernardo BSG 60220 PLC Surface Grinding Machine with 2-axis DRO

The Bernardo BSG 60220 PLC surface grinding machine with ES-12 H 2-axis digital readout is a large industrial machine, designed for high-precision grinding of heavy workpieces up to 1700 kg. The 600 x 2200 mm table, with hardened and ground guides and Durcit-B coated counter-guides, ensures rigidity and smooth operation even under intensive loads. Longitudinal and transverse movements occur on combined V-flat guides, while the latest generation hydraulic system ensures fluid and regular translations. The Siemens PLC control with touchscreen allows programming automated grinding cycles, such as roughing, finishing, and automatic return to the initial position. With a 350 mm grinding wheel, a 7.5 kW motor, and a 5.5 kW hydraulic pump, the BSG 60220 is the ideal choice for workshops and companies that require a robust, precise, and highly productive surface grinding machine.

Frequently Asked Questions

What is the achievable grinding precision with the Bernardo BSG 6 surface grinding machine?

Bernardo surface grinding machines achieve dimensional tolerances of IT5–IT6 and surface 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 mean in the Bernardo BSG 6 surface grinding machine model?

The PLC suffix indicates that the grinding machine 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 batches of identical parts.

What grinding wheel should be used for steel vs cast iron vs aluminum?

Steel: aluminum oxide (Al₂O₃) A46K–A60K grinding wheel. Cast iron: silicon carbide (SiC) C46K–C60K grinding wheel. Aluminum: silicon carbide C46J–C60J grinding wheel 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 grinding machine require integrated coolant?

BSG and FSM surface grinding machines are equipped with an integrated cooling system — essential for precision grinding of hardened steel to avoid 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 in Italian available.
