Frequently Asked Questions
What can the industrial DS 400 S / 400 V grind?
Stainless steel, aluminum, metal alloys and (in some models) also wood with appropriate abrasive belts.
For each material, a specific belt grit is used: 60-80 for roughing, 120-180 for finishing, 240+ for pre-polishing.
What abrasive belt sizes does it use?
See "Belt dimensions" in the technical table: typically from 75x2,000 mm to 150x2,500 mm.
Belts are consumables: Krollit supplies original Bernardo belts in various grit sizes to optimize the finish.
Is the belt speed adjustable?
Professional models offer Vario or multi-step speeds (typically 4-8 steps).
High speeds (>20 m/s) for stainless steel and finishing, low speeds (<10 m/s) for wood and soft materials to avoid burning.
Does it have integrated dust extraction?
Professional models offer a dust extraction port for grinding dust.
Dust extraction is essential for stainless steel (respirable dust) and for wood (fire risk from sparks). Check the connection diameter for connection to a centralized system.
How much does the machine weigh?
See "Weight" in the technical table: typically 50-200 kg for bench and column models.
Column models require floor mounting, while bench models are installed on a sturdy bench of adequate size.
