Large diameter anti-vibration boring bar
- December 6, 2021
Walter has expanded its Accure-tec vibration dampening boring bar line with larger boring bar diameters.
Walter’s new A3001 anti-vibration boring bar features a greater diameter, delivers improved surface finishes, and eliminates time-consuming "fine tuning."
The A3001 boring bar has been introduced in combination with the A2201 intermediate offset adaptor for larger diameter bores.
The standard A2201 is an offset adaptor for reduced radial forces and greater stability, providing more space between the boring bar and the bore wall for improved chip removal with very deep bores. With the A3001 and the A2201 Walter has increased boring bar diameters to 2.5 – 4 in. and 60 – 100 mm. Unlike conventional steel or solid carbide boring bars that are often ineffective at length/diameter ratios beyond 6 x Dc, the Accure∙tec A3001, with its patented vibration dampening system, excels at length/diameter ratios beyond 6 x D up to 10 x D — well past the point where conventional steel or solid carbide boring bars often prove less efficient.
The Accure∙tec A3001 and A3000 boring bars eliminate the time-consuming "fine tuning" of the dampening function, as the anti-vibration feature is preset at the factory, so the tool is ready for quick application. The new tool is available with both negative and positive inserts.
