G20242R/L grooving blades can be supplied as left- and right-handed variants, in both standard and contra versions. The contra design is particularly useful when grooving in the immediate vicinity of the machine spindle, when the tool shank traditionally reduces available clearance.
G2012-P toolholders with through-coolant are now also available in shank diameters of 12 and 16 mm, complementing the existing 20 and 25 mm versions. The smaller sizes will prove especially suited to use on multi-spindle autos, for example.
Walter Cut-SX tools feature precisely-matched grooving inserts and insert holders, a ‘rounded’ positive locking insert shape with form-fit underside and a sturdy top clamp.
Compared to conventional inserts, Walter Cut-SX offers significantly increased process reliability because a positive locking insert cannot be ‘lost’ during machining – such as when the insert is pulled from the holder when the workpiece and bar separates during part-off.
In addition to these standard tools, Walter GB also offers a new clamping system that holds out the promise of tool life increases of up to 30%, plus greater process reliability for grooving and roughing slots in large components.
For example, in the machining of turbine shafts of up to three metres diameter by 15 metres long - where slots of up to 100 mm wide and deep are required - a widely-used approach is to apply a 19 mm wide grooving insert and to progressively open up the slot in steps of 8-10 mm. With Walter’s stable clamping system, slots can be expanded by up to 18 mm in each pass and the improved chip breaking from these innovative geometries enables swarf to be generated cleanly and reliably, leading to improved process reliability.
