Frequently Asked Questions
What can the 230 V grind?
HSS drill bits, end mills, disc cutters, and cutting tools within the dimensional limits of the model.
Grinding capacity is limited by the grinding wheel diameter and angular adjustment. For carbide tools (HM), verify CBN/diamond wheel compatibility.
What grinding precision does it offer?
Bernardo professional models allow grinding with tolerances of ±0.02 mm on the cutting angle.
Precision depends on the machine's rigidity and the quality of the guides. Models with fine calibration allow angular adjustment to a tenth of a degree.
What type of grinding wheel is supplied?
Corundum grinding wheel for standard HSS grinding. For HM, a CBN or diamond wheel is needed, purchased separately.
Krollit supplies original Bernardo replacement grinding wheels with delivery times of 3-5 business days.
Does it have a cooling system?
Professional grinders offer manual drip cooling or a dedicated pump.
Cooling prevents tempering of the tool during grinding and maintains edge hardness. For delicate grinding, it is essential.
How much does the machine weigh?
See the "Weight" data in the technical table: professional models weigh from 50 to over 200 kg.
Benchtop grinders are installed on a sturdy workbench, while column models require floor mounting for stability.
