Walter USA's Accure-tec A3000 Boring Bar Features Vibration Damping
Walter USA’s Accure-tec A3000, with its vibration damping system, is designed to excel beyond 6 × Dc.
Walter USA’s Accure-tec A3000 features a vibration damping system that enables it to excel at length/diameter ratios beyond 6 x Dc. The tool is available in lengths of 6, 8, and 10 × Dc; boring bar diameters of 1.25", 1.50" and 2.00" (32, 40 and 50 mm); and Capto C6, C8 and HSK100T connections. Additional sizes and lengths are available on request. The boring bars feature QuadFit quick-change exchangeable heads. The tool is available with both negative and positive inserts.
Internal coolant delivery for optimum chip removal improves surface finish and enables counterboring and internal profiling of parts in industries such as aerospace, oil and gas, and general metalworking.
The Accure-tec A3000’s anti-vibration feature is preset at the factory for faster implementation. As such, the company says that users will not have to spend much time fine-tuning the damping function.
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.
Cutting holes by interpolating a face milling cutter may be a better process choice for many rough and even finish boring operations. Software improvements and better cutter designs allow expanding use of the versatile face mill for hole making.
