Frequently asked questions
How do you choose the grit size of the grinding wheels for the Bernardo DS 1 Double Grinder?
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 DS 1 Double Grinder uses Ø 175 mm wheels — check the correct format 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. An unbalanced or misshapen wheel can cause excessive vibrations and risks to the operator.
Can the Bernardo DS 1 Double Grinder mount a leather or felt disc for polishing?
Yes. Most Bernardo double grinders can mount Ø 175 mm leather or felt discs on the same shaft as the abrasive wheels — suitable for polishing metals, plastics, and wood. Check shaft compatibility with Krollit.
What is the difference between DS and DSA in the grinder range?
The DS series is the standard double grinder with an abrasive 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 working days shipping. Customer support in Italian available.
