Walter USA Adds PCD Inserts to Its Cut GX Grooving Series
Walter USA has added polycristalline diamond (PCD) grooving inserts to its Walter Cut GX grooving system.
Walter USA has added polycristalline diamond (PCD) grooving inserts to its Walter Cut GX grooving system. These straight-edge (F1) and full-radius (M1) geometries are designed for grooving in aluminum and titanium alloys, enabling high cutting speed, lengthening tool life and improving surface quality in grooving, parting and recessing operations. The inserts are said to be ideal for aerospace, medical device and automotive applications.
The wear-resistant WDN10 PCD grade provides high hardness, a low coefficient of friction and minimal heat distortion for high-speed machining of nonferrous materials.
The GX24-WDN10 inserts feature chipbreaker geometry, laser-marked ISO and ANSI corner-radius designation, and widths ranging from 0.078" to 0.118" (2 to 8 mm).
Creating threaded holes in titanium alloys calls for proper techniques based on an understanding of both the properties of these materials and the peculiarities of the tapping process.
Running rotary milling cutters at the proper speeds and feeds is critical to obtaining long tool life and superior results, and a good place to start is with the manufacturer's recommendations. These formulas and tips provide useful guidelines.
One of the most common methods of tapping in use today on CNC machines is 'rigid tapping' or 'synchronous feed tapping.' A rigid tapping cycle synchronizes the machine spindle rotation and feed to match a specific thread pitch. Since the feed into the hole is synchronized, in theory a solid holder without any tension-compression can be used.
