Adding Life is a Plus with New Grade ( May. 22. 2014 )

Extending the life of inserts that perform under the stress of higher cutting conditions is of the utmost importance for TaeguTec so to further this goal the Asian metalworking giant has launched the Life grades for steel machining.

The upgraded TT8115, TT8125 and TT8135 grades with new cutting edge coating technology outperform current grades like never before and are an excellent upgrade to TaeguTec’s highly popular GoldRush line.

The Life new grades have excellent wear resistance, are stable in high-feed and speed machining conditions, and are an ideal choice for professional and amateur machinists who aim to achieve excellent surface roughness while minimizing build-up-edges.

By emphasizing productivity, the new coating guarantees longer tool life under higher cutting conditions over the currently existing ones while the improved coating surface treatment technology prevents chipping even in interrupted cutting on a wide range of applications, and simplifies both the process of predicting a tool’s life and automated machining.

Specifically under alloy steel and high hardness material machining where high temperature and pressure are a challenge, the special coating technology efficiently mitigates the impact to achieve higher productivity over conventional cutting tool grades.

After extensive internal and field testing in real world machining conditions, the newly upgraded TT8115, TT8125 and TT8135 increased tool life by as much as 120 percent on a variety of machining conditions and types of alloy steel and high hardness materials.

The most impressive result from real-world tests happened during the strenuous conditions of interrupted cutting on an alloy steel part where the feed rate was 0.15 mm/rev and a speed rate of 250 m/min. In this test, the Life TT8125 grade recorded a 20% increase in tool life.

In another test, the life of a tool treated with the Life TT8125 was increased by 100 percent while machining cast metal at speeds of 310 m/min and a feed rate of 0.3 mm/rev.

During the machining of a gear ring made from bearing steel, the internal turning procedure recorded a 66 percent increase in tool life, which equated to a 13 percent increase in productivity, while also using the Life TT8125 grade.

By increasing the cutting speed to 160 m/min while keeping the feed rate at 0.35 mm/rev and a depth of cut of 1 mm, the Life TT8125 grade recorded an increase of 33 percent in tool life and a productivity increase of 22 percent.
