Frequently Asked Questions
What sanding width does it offer?
See "Max sanding width" in the technical table.
For panels wider than the nominal capacity, sanding in multiple passes with precise alignment is required.
What is the minimum and maximum thickness it can process?
See "Min.–max. workpiece thickness" in the technical table.
For thin workpieces, the use of anti-vibration supports is recommended to maintain uniform pressure.
Does it have multiple sanding stations?
Professional models offer 2-3 stations with different grits for roughing and finishing in a single pass.
Multiple stations reduce processing times and standardize finishing quality.
What power supply does it require?
Typically 400 V three-phase for professional models.
Check the capacity of the electrical line and the presence of a dedicated residual current device.
How much does the machine weigh?
See "Weight" in the technical table: industrial models weigh from 500 to over 1500 kg.
Machines above 800 kg require industrial flooring and handling with a forklift during installation.
