Frequently asked questions
How do I choose the grit of the grinding wheels for the Bernardo Double Grinder DSA?
For roughing and heavy material removal: coarse-grit wheel (36–60). For tool sharpening and precision work: medium-grit wheel (80–120). For finishing and polishing: fine-grit wheel (150–220) or felt disc. The Bernardo Double Grinder DSA uses Ø 200 mm wheels — check the correct size before purchasing spare parts.
How often should grinding wheels be balanced?
New grinding wheels should always be checked before installation (ring test — clear sound = intact wheel). Periodic dressing with a wheel dresser maintains the correct shape and reduces vibrations. A misaligned or out-of-shape wheel can cause excessive vibrations and risks to the operator.
Can the Bernardo Double Grinder DSA mount a leather or felt disc for polishing?
Yes. Most Bernardo double grinders can mount leather or felt discs Ø 200 mm on the same arbor as the grinding wheels — suitable for polishing metals, plastics, and wood. Check arbor compatibility with Krollit.
What is the difference between DS and DSA in the grinder range?
The DS series is the standard double grinder with a grinding wheel on both sides. The DSA series adds integrated dust extraction — essential when working on materials that produce fine dust (aluminum, non-ferrous metals, wood) in enclosed environments. The DSA is quieter and keeps the work environment cleaner.
Are spare parts (wheels, supports) available?
Original spare parts available with 3–5 business days shipping. Italian customer support available.
