Description
Bernardo BSG 2040 PLC Surface Grinding Machine
The Bernardo BSG 2040 PLC is a professional surface grinding machine (tangential grinding machine) equipped with a Siemens PLC control with touchscreen, allowing intuitive programming of simple and repeatable grinding cycles. The advanced hydraulic system with a separate unit and heat exchanger ensures smooth table movements even under heavy loads, reducing vibrations and thermal deformation. The 200 x 500 mm table, with a longitudinal travel up to 560 mm and a transverse travel up to 240 mm, allows processing of workpieces up to 180 kg with a magnetic chuck. The vertical feed is servo-assisted and digital, with resolutions up to 0.005 mm. Includes a 2-axis digital display, 200 x 460 mm magnetic chuck, Ø 200 mm grinding wheel, cooling system, and central lubrication. A robust machine (1640 kg) that combines automation and precision, ideal for mechanical workshops and production departments.

Frequently Asked Questions
What is the achievable grinding precision with the Bernardo BSG 2 surface grinding machine?
Bernardo surface grinding machines 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 mean in the Bernardo BSG 2 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.
Which abrasive wheel should be used 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 — metallic residues contaminate the ground surface.
Does the Bernardo BSG 2 surface grinding machine require an integrated coolant?
BSG and FSM surface grinding machines 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.
Spare parts and grinding wheels available?
Original spare parts available with 3–5 working days shipping. Customer service available in Italian.
