Tooling Line Now Includes Threading Inserts, Round Shank Holders
Tungaloy is expanding its DuoJustCut line to include threading inserts and round shank holders to further its position in small-part machining industries. DuoJustCut can now line up threading inserts for front as well as back turning operations, incorporating a highly rigid clamping method to prevent the insert from moving during high-feed machining. The SH725 PVD grade extends tool life. Even if the first cutting edge is fractured, the other cutting edge can be used thanks to its unique insert clamping method. One type of threading insert and three types of parting-off inserts are now available for use in a single holder. This feature, along with the new round shank toolholder lines, will facilitate tooling in the Swiss-type machine market.
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.
The right choices in tooling and technique can optimize the thread turning process.
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.
