Grooving Tools Come in Three Styles for Different Industries
Arno Werkzeuge USA introduces its SA series of cutting tools and inserts for grooving and parting-off or cutoff operations. The modular grooving system, using a single toolholder, can be transformed into different tool variants by changing the support blade and clamp. Enabling different operations with one tool, this grooving system provides chip removal in all three main cutting directions. The SA range also features precision-ground two- or three-edged cutting inserts in various designs, shapes and types to maximize cutting performance, speed and efficiency.
The series comes in three unique systems—monoblock, modular and blade-style—to accommodate the requirements of machining operations in aerospace, plastics and medical industries. The company says the SA series provides a cost-effective solution for radial grooving as well as parting off of diameters ranging to 5.512" (140 mm). The SA monoblock holder is used with a range of double-sided inserts including the Arno SA16, SA17, SA24, SA35 und SA40 in widths of 0.059", 0.079", 0.118", 0.157", 0.197", 0.236", 0.315 " and 0.394" (1.5, 2, 4, 5, 6, 8 and 10 mm).
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.
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.
