Tungaloy is introducing the WavyJoint PCBN inserts, an innovative PCBN brazing technology for higher productivity in hard turning operations.

Hardened steel parts are gaining broader acceptance in today's automotive industry to meet the requirements of downsizing for less emission and energy. Manufacturers are seeking cost-effective solutions to improve productivity and machining efficiency. PCBN inserts are an effective solution to turn hardened steel parts.

However, a PCBN tip brazed with a conventional brazing technology is prone to detach, or debraze, from its carbide base insert when turned dry at a large DOC. Therefore, the operator has to use multiple, small cutting depth passes. The WavyJoint PCBN insert can significantly improve machining efficiency, enabling hard turning in a single pass at a large DOC and at a high feed rate.

At a glance:

Innovative brazing method allows for a large DOC, up to 1.6 times that of conventional PCBN inserts.

Larger PCBN mass of the cutting tip enhances thermal stability during deep and dry cutting.

Capable of a DOC up to 0.8 mm. Fewer turning passes for higher efficiency.

Reduced risk of debrazing allows for dry and interrupted cutting at a large DOC.

Reduces premature insert failures caused by thermal fatigue often seen in wet cutting.
