Valve seat machining with HNHX indexable inserts
More cutting edges for lower cost per part.
To further lower the cost per part when machining valve seats in the cylinder head, MAPAL has developed the new HNHX indexable inserts.With up to 24 usable PcBN cutting edges, they are not only particularly economical but also make the most effective use of the cutting material. Thanks to the high-quality cutting edges, the new HNHX indexable inserts allow for surface finishes greater than Ra 0.2 μm.
The newly designed machining star guarantees uniform pressure distribution when clamping the indexable insert. The development expands the range of application for valve seat tools because the clamping screw had previously prevented their use in certain valve seat diameter ranges.
