Tools such as drills, milling cutters or thread rolls must have precisely defined surface structures and rounded edges for optimum machining results. A surface finish after grinding is therefore essential for high-quality tools.
Drill bits, milling cutters, indexable inserts, roller burnishing tools (knurling and thread rolls)
Defined edge rounding and polishing
Material-independent (HSS, chrome etc.)
Cutting edge rounding indexable insert
HSS, 15x15 mm
Cutting edge rounding 0.02 mm
Cutting edge rounding end mill
Hard metal, 70x12 mm
Cutting edge rounding 0.012 mm
Polished clamping bolt
Stainless steel, 30x25 mm
Task: descaling, polishing to Ra 0.5 µm
By drag grinding, brushing or blasting, the edges of tools can be rounded in a defined way and the surface roughness can be reduced. This means that higher feed rates can be used for longer tool life.
