Description
Bernardo BSG 50160 PLC – Surface Grinding Machine with 2-axis DRO
The Bernardo BSG 50160 PLC surface grinding machine with ES-12 H 2-axis digital readout is designed for high-precision industrial grinding. The 500 x 1600 mm worktable, with hardened and ground guideways and Durcit-B coated counter-guideways, ensures rigidity, smooth operation, and long service life. Longitudinal and transversal movements are achieved via combined V-flat guideways, while the advanced hydraulic system ensures smooth translations even under heavy loads. The Siemens PLC control, with a touchscreen panel, allows for quick programming of grinding cycles, including roughing, finishing, and automatic return to the initial position. With a working capacity of up to 900 kg, a 350 mm grinding wheel, and a 7.5 kW motor, the BSG 50160 PLC represents a robust, stable, and efficient solution for workshops and companies requiring a professional hydraulic surface grinding machine.

Frequently Asked Questions
What is the achievable grinding precision with the Bernardo BSG 5 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 5 surface grinder model?
The PLC suffix indicates that the grinder is equipped with a programmable PLC control — it allows for setting automatic grinding cycles (number of passes, depth per pass, feed rate) without manual intervention during the cycle. Compared to the manual version, it reduces cycle times and produces more repeatable results for identical batches of parts.
Which grinding wheel to use 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 5 surface grinder require an integrated coolant system?
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.
