Walter (Waukesha, WI) has expanded its Accure∙tec anti-vibration boring bar line with the addition of the A3001 boring bar in combination with A2201 intermediate offset adaptor for larger diameter bores.
The standard A2201 is an offset adaptor for reduced radial forces, greater stability and provides 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.
Of prime importance is the fact that users of the Accure∙tec A3001 or A3000 boring bars will not have to worry about time-consuming "fine tuning" of the dampening function, as its patented 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.
