Frequently asked questions
What can the UWS 350 sharpen?
HSS drill bits, end mills, disc cutters, and cutting tools within the dimensional limits of the model.
Sharpening capacity is limited by grinding wheel diameter and angular adjustment. For carbide tools (HM), verify CBN/diamond 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 machine rigidity and guide quality. Models with fine calibration allow angular adjustment to the tenth of a degree.
What type of grinding wheel is supplied?
Corundum grinding wheel for standard HSS sharpening. For HM, a CBN or diamond wheel needs to be purchased separately.
Krollit supplies original Bernardo replacement grinding wheels with delivery times of 3-5 working days.
Does it have a cooling system?
Professional grinding 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 grinders are installed on a robust workbench, while column models require floor mounting for stability.
