Productive Alternative to Groove Milling

The CoroBore 825 SL face grooving heads are available from Sandvik Coromant. According to the company, this rotating axial face grooving tool 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," said a company spokesperson. "This, in combination with high levels of rigidity, is intended to provide increased cutting data. Chip evacuation is a concern in any metalcutting operation but is critical when grooving because chips are more prone to being trapped inside a groove and being re-cut. As a result, through-tool coolant delivered right to the cutting edge can be enormously beneficial."

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 (1.85" - 5.91" /47-150 mm) C6 and C8 adaptors are available, while for larger diameters (>5.91" /150 mm) a dedicated face grooving head with CoroBore XL can be deployed.

The first choice insert geometries are -CM for small nose radii (<0.0078" /0.2 mm) or -TF for larger nose radii (>0.0078" /0.2 mm), and the recommended starting value for feed rate is 0.006 in/rev (0.15 mm/rev). However, if grooves with smaller width tolerances are required -GF geometry is the preferred choice. Here, a feed rate of around 0.004 in/rev (0.10 mm/rev) is the recommended starting value.

CoroBore 825 SL face grooving technology can be used for applications such as producing O-ring grooves. For applications involving other shapes, such as V-grooves, tailor made insert technology is available.
