WNT combines substrate and coating technology developments in HCR1335 and HCN1345 grooving inserts

HCR1335 and HCN1345, the latest insert grades to join WNT's expanding Dragonskin range, target grooving applications where they can provide increased tool life, process security and overall performance.

Development of the HCR1335 and HCN1345 Dragonskin grades is the result of WNT's investment in substrate and coating technology. The combination allows increased cutting data to be applied across a wide range of steels, including stainless steel. HCR1335 with its high edge stability and hardwearing characteristics is suitable for difficult machining conditions, such as interrupted cutting. It can provide enhanced process security at cutting speeds of up to 220 m/min and feedrates up to 0.28 mm/rev when grooving and parting (0.3 mm/rev when side turning). HCN1435 is suggested for universal applications where the substrate and grade allow the insert to perform at elevated cutting data across a much wider range of steel materials and cutting conditions. Both insert grades are available in three single-ended styles and one double-ended, with a choice of chipbreaker. The GX double-ended inserts provide the highest versatility for parting and grooving and, depending on the chipbreaker, are suitable for thin-walled workpieces and also offer a polished geometry for stainless steel. The SX single-ended inserts are suitable for parting, grooving and copy turning, while the LX single-ended insert targets more extreme applications producing grooves up to 8 mm in width. Finally, the FX single-ended style is capable of machining a wide range of parts including those with thin walls, where its sharp geometry comes into its own, says WNT. These latest Dragonskin inserts will have available for discussion at WNT's open house at its Sheffield Technical Centre on the 23-24 January and at Southern Manufacturing 13-14 February 2013.
