This product family is a 3-piece parting/grooving assembly system that consists of a single-edge insert, parting blade and blade holder. They offer excellent operating rigidity, and a broad parting or grooving depth range. You can follow the steps below to select the assembly to suit your application:
1. Insert Selection: Select sing-edge parting insert from the single-edge insert group based on desired cutting edge width (S) (or W for parting blade in Step 2). For parting application, cutting edge width may not be as critical as other parameters explained in the following steps.
2. Blade Selection: Blade is holder of parting/grooving insert. Once an insert is chosen, go to the parting blade group to select appropriate parting blade to match the insert. ΦD(max) is an important parameter that indicates the maximum parted workpiece diameter or the deepest groove to be machined. There are 2 size groups of blades in terms of Height (H) and length (L): one group has H and L of 4.331” and 1.024”, and the other 5.906” and 1.260”.
3. Parting Blade Holder Selection: After a parting insert and blade are chosen, go to the blade group to select an appropriate parting blade holder. There are two sizes of the blade holders in terms of total length (L): 3.386” and 4.331”. As a rule of the selection, QZS_-26 blade holders (L=3.386”) match QE_ -26N blades, and QZS_ -32 blade holders (L=4.331”) match QE_ 32N blades. Then among different variations, choose the one that has an appropriate cutting height (H).
You may need to go through a couple of iterations to optimize and finalize your selection. Contact customer service if you have any questions.
