To overcome various machining challenges and boost productivity,
Seco has introduced new toolholders, PCBN inserts, round carbide inserts and extra-long solid-carbide drills. For example, Seco’s new X-tra Long solid-carbide drills accommodate hole depth from 40xD to 60xD, while offering enhanced versatility and ‘15% greater tool life than other extra-long solid-carbide drills’.
Seco says they achieve fast, reliable performance in steel, stainless steel and cast iron, as well as good performance in Inconel, titanium, and hardened steel on standard machining centres. Furthermore, these drills feature a tool geometry and coating designed to eliminate chipping and sudden breakage while minimise flank wear and centre wear — and they maintain specified drilling depth after up to three reconditioning cycles.
Meanwhile, two new grades of PCBN inserts have been introduced for high-volume production in industries such as automotive, with CH1050 designed for finishing and CH2581 for semi-interrupted cuts. CH1050 features Seco’s ‘nanolaminate PVD coating’ for high levels of surface quality requirements; it also offers a high-accuracy edge preparation via a new grinding process. CH2581 offers process stability and reduced tool breakage via a grade specifically designed for semi-interrupted cuts, while its high-accuracy edge prep and next-generation Seco PVD coating accommodate fast speeds.
While many round turning inserts suffer from poor chip control, Seco’s MF2 chip breaker on RCGT/RCMT inserts has been designed to ensure good chip control at high speeds and feeds, such as encountered with ‘dynamic turning’. Seco says its chipbreaker geometry and strong insert shape provide reliable performance in tough operations, with materials ranging from ‘smeary’ low-carbon steels to stainless steels, titanium, and heat-resistant super alloys.
Meanwhile, for optimum surface finishes with Seco-Capto MTM JETI toolholders for general ISO turning, the company has used its 3-D printed coolant clamp to deliver high-pressure cutting fluid directly to the cutting edge; and with a range of single-screw coolant clamp options for specific applications and depths of cut, these toolholders provide fast set up and indexing, making chip control less of a challenge on 45deg B-axis multi-tasking machines.
Furthermore, Seco-Capto MTM JETI toolholders allow for the use of ‘shorter tooling’ with greater reach, less overhang and reduced collision risk.
