Small Inserts Reduce Cost
Iscar’s Flashturn Eco line includes small-sized Isoturn inserts said to provide decreased cost per cutting edge.
Iscar’s Flashturn Eco line includes small-sized Isoturn inserts said to provide decreased cost per cutting edge. The inserts are available in a range of geometries, corner radii, chipformers and Sumo Tec carbide grates. WNMG 33, WNMX 34, CNMG 33, CNMX 34, SNMG 33, DNMG 33, TNMG 33 and TNMX 34 geometries are available. The inserts are generally thicker than standard inserts in the same sizes, therefore increasing durability while running at feed rates similar to the larger inserts, the company says.
The 3/8" inscribed circle inserts with WNMG 33 geometry, for example, can cover turning applications in depths of cut ranging from 0.03" to 0.12". According to the company, this range accounts for about 75 percent of turning applications, and the insert is capable of handling these applications with reduced costs over the ½" inscribed circle insert size.
With macros and canned cycles resident in the CNC on most contemporary turning centers, single point turning of OD threads can seem like almost a default process decision. However, for numerous applications, OD thread rolling has inherent advantages as an alternative to cutting threads.
The more common twist drill point geometries often are not the best for the job at hand. By choosing the best point for the material being drilled, it is possible to achieve better tool life, hole geometry, precision, and productivity.
To make the transition to hard turning, you'll need to switch from carbide to CBN inserts, but that is easier (and more economical) than you might think. It's making the jump to much higher surface speeds that might scare you off. It needn't. Here's why.
