Vibration Dampening Boring Bar Features Greater Diameter Capabilities

Walter USA 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. It provides for fast, productive counterboring and internal profiling of parts in industries such as aerospace, oil and gas and general metalworking.

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" and 60-100 mm. Unlike conventional steel or solid carbide boring bars that are often ineffective at length/diameter ratios beyond 6xDc, Walter’s Accure∙tec A3001, with its patented vibration dampening system, is said to excel at length/diameter ratios beyond 6xD up to 10xD.

The vibration dampening system is preset at the factory, eliminating the need for fine-tuning of the dampening function prior to use, the company says. The new tool is available with both negative and positive inserts.

Complementing the A3001, Walter offers Capto C6, C8 and HSK-T 100 connections, and QuadFit precision (± 0.002 mm) quick-change exchangeable heads for decreased downtime and boosted versatility.

Walter’s other existing A3000 anti-vibration boring bar product line offerings do not require the A2201 intermediate adaptors, and cover a diameter range of 1-2" and 25-50mm; they are also offered with Capto C4, C8 and HSK-T 63-100 connections.
