Productive Alternative to Milling Grooves

Machine shops seeking competitive gain in face grooving applications should look no further than CoroBore® 825 SL face grooving heads from tooling specialist, Sandvik Coromant US (Fair Lawn, NJ). 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 solution 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 a concern in any metalcutting operation, but it 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 mm to 1,275 mm. For smaller diameters (1.85 in to 5.91 in/47 mm to 150 mm) C6 and C8 adaptors are available, while for larger diameters (>5.91 in/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 in/0.2 mm), 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, then -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.

At last there is a high-productivity alternative to milling grooves, axial face groove machining for applications such as producing O-ring grooves has never been easier using CoroBore 825 SL face grooving technology. For applications involving other shapes, such as V-grooves for example, Tailor Made insert solutions are available.
