Big Kaiser Offers Insert Grades for Cutting Stainless Steel, Aluminum
Big Kaiser’s has released a new set of insert grades for its C-Cutter Mini, C-Centering Cutter and Fullcut Mill tool products.
Big Kaiser has released a new set of insert grades for its C-Cutter Mini, C-Centering Cutter and Fullcut Mill tool products. The new inserts are optimized to extend tool life when machining stainless steel or aluminum.
Suited for peck-drilling, ramping, and helical and shoulder milling, the Fullcut Mill is now available with the PVD-coated carbide ACP300 having nanometer-level thickness and multilayered TiAIN and AICrN film, replacing the ACZ350S for general steel applications. Another insert, the ACM300F, is designed specifically for stainless steel work, with fracture and welding resistance.
The ACM250F stainless steel grade can be used for chamfering and spot drilling with the C-Cutter Mini or C-Centering Cutter. The PVD-coated carbide insert resists welding and chipping thanks to the multilayered thin film structure made of AlTiN and TiAlCrN. The ACM250F replaces the ACZ150 used with the C-Centering Cutter.
The DS20 for aluminum/non-ferrous metals is also available for the C-Centering Cutter. Its diamond-like DLC coating is described as ultra-smooth, whose low wear coefficient and welding resistance effectively prevent burrs.
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.
Liquid coolant offers advantages unrelated to temperature. Forced air is the fluid of choice in this shop...but even so, conventional coolant can't be eliminated entirely.
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.
