Tungaloy's BXA20 T-CBN Inserts Resist Fracturing and Wear
Tungaloy has added 22 shapes and geometries to its BXA20 line of coated T-CBN inserts designed for hard turning operations.
Tungaloy has added 22 shapes and geometries to its BXA20 line of coated T-CBN inserts designed for hard turning operations. The inserts include wiper geometries and WavyJoint technology to address a broader range of hard part turning needs.The company says that the products are suited for a variety of applications.
The BXA20 insert has a nano-multilayered physical vapor deposition (PVD) coating twice as thick as conventional grades and coated on a polycrystalline cubic boron nitride substrate, adding wear and fracture resistance to the grade.
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.
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.
