Separator™ Machining Guidelines Definitions and Guidelines • If 0° lead angle is mandatory, 1. Width of cut (W) = width of the insert. use the narrowest possible cut-off insert and blade. This 2. Lead angle = 0° (neutral); 4°, 5°, 12°, 18° (RH or LH). will minimise the centre stub or cut-off bur length. Decrease the feed rate to maximum 0,05mm or less at the point where diameter equals insert width. Reduce bur of cut-off faces: • On tubing-type parts that • Use lead angle-type inserts (Figures 1 and 2).

This will enable thechamfering operation to actuallyInternal chamfer line up separate the part from the bar (see Figure 4). Note the part may drop onto the chamfering bar, which, in this case, will act Figure 1 like a catcher for the part. Insert selection left-hand lead centre stub bur part Improve surface finish of cut-off faces: (stock) (stock) • Use insert with 0° lead angle. • Increase coolant flow or improve application technique, as shown in Figure 5. cut-off to centre tube cut-off • Decrease the feed rate near the break-through point of the cut. • Check that the grooving tool is set at the correct angle. Left-hand lead insert leaves centre stub or bur on partand produces clean stock surface.• Use blades with the greatest possible face height and smallestpossible cutting width.

Figure 3 Figure 5 Above centre Preferred method for applying coolant • Mount cut-off tool upside down. This enables gravity to remove chips and avoid cutting the chips twice. Another benefit of mounting the tool upside down is preventing chips from wedging max 0,10mm(.004") between the tool insert and the groove side walls, which galls the side wall surfaces.
