Frequently Asked Questions
What can the UWS 300 sharpen?
HSS drill bits, end mills, disc cutters, and cutting tools within the model's dimensional limits.
Sharpening capacity is limited by the grinding wheel diameter and angular adjustment. For carbide (HM) tools, check CBN/diamond grinding wheel compatibility.
What sharpening precision does it offer?
Bernardo professional models allow sharpening 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 sharpening. For HM, a CBN or diamond grinding wheel needs to be purchased separately.
Krollit supplies original Bernardo replacement grinding wheels with delivery times of 3-5 business days.
Does it have a cooling system?
Professional sharpening machines offer manual drip cooling or a dedicated pump.
Cooling prevents tempering of the tool during sharpening and maintains the hardness of the edge. It is essential for delicate sharpening.
How much does the machine weigh?
See the "Weight" data in the technical table: professional models weigh from 50 to over 200 kg.
Benchtop sharpening machines are installed on a sturdy bench, while column models require floor mounting for stability.
