Sandvik Coromant introduces CoroBore 825 SL face grooving tool
1 min read
Sandvik Coromant says its rotating axial face grooving tool CoroBore 825 SL offers a productive alternative to milling grooves for those operating in, or serving sectors such as pumps and valves, hydraulics and the pulp and paper industry.
The CoroBore 825 SL uses a standard SL32 blade and CoroCut 1-2 inserts, but features through-coolant capability for enhanced chip control. This, in combination with high levels of rigidity, allows increased cutting data. Chip evacuation is critical when grooving because chips are more prone to being trapped inside a groove and being re-cut, so coolant is delivered right to the cutting edge.
CoroBore 825 SL face grooving heads offer radial fine adjustment for presetting purposes and are available for diameters from 47 to 1,275 mm. For smaller diameters (47 to 150 mm) C6 and C8 adaptors are available. A dedicated face grooving head with CoroBore XL can be deployed for diameters over 150 mm.
First choice insert geometries are -CM for small nose radii (below 0.2 mm) or -TF for larger nose radii (over 0.2 mm) – the recommended starting value for feedrate is 0.15 mm/rev. For grooves with smaller width tolerances -GF geometry is offered with a recommended starting value feedrate of 0.10 mm/rev.
Sandvik Coromant adds that while CoroBore 825 SL face grooving technology makes producing O-ring grooves easier than ever before, Tailor Made insert solutions are available for other shapes, such as V-grooves.
