Walter has unveiled its new Accure · tec anti-vibration A3000 boring bar. Unlike conventional steel or solid carbide boring bars that are often ineffective at length/diameter ratios beyond 6 x Dc, the new Accure∙tec A3000, with its patented vibration dampening system, actually excels at length/diameter ratios beyond 6 x Dc -- the point where those conventional steel or solid carbide boring bars often prove less efficient.
Available in lengths of 6, 8, and 10 x Dc and boring bar diameters of 1.25, 1.50, and 2.00 in. (32, 40, and 50 mm) with additional sizes and lengths available on request. Capto C6, C8 connections along with HSK100T connections are also offered as standards. The new boring bars feature compact, robust QuadFit precision quick-change exchangeable heads which boost versatility and decrease downtime.
Internal coolant delivery for optimum chip removal is a feature that adds to the superior surface finishes obtained by the Accure∙tec A3000. It provides for fast and productive counterboring and internal profiling of parts in industries such as aerospace, oil and gas, and general metalworking.
Users of the new Accure∙tec A3000 boring bar will not have to worry about time-consuming "fine tuning" of the dampening function, as the 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. In addition, with the new Accure∙tec A3000 anti-vibration boring bar for turning, maximum productivity is ensured by its use of Tiger·tec Silver grades.
Related Glossary Terms
Enlarging a hole that already has been drilled or cored. Generally, it is an operation of truing the previously drilled hole with a single-point, lathe-type tool. Boring is essentially internal turning, in that usually a single-point cutting tool forms the internal shape. Some tools are available with two cutting edges to balance cutting forces.
- boring bar
Essentially a cantilever beam that holds one or more cutting tools in position during a boring operation. Can be held stationary and moved axially while the workpiece revolves around it, or revolved and moved axially while the workpiece is held stationary, or a combination of these actions. Installed on milling, drilling and boring machines, as well as lathes and machining centers.
Fluid that reduces temperature buildup at the tool/workpiece interface during machining. Normally takes the form of a liquid such as soluble or chemical mixtures (semisynthetic, synthetic) but can be pressurized air or other gas. Because of water’s ability to absorb great quantities of heat, it is widely used as a coolant and vehicle for various cutting compounds, with the water-to-compound ratio varying with the machining task. See cutting fluid; semisynthetic cutting fluid; soluble-oil cutting fluid; synthetic cutting fluid.
Enlarging one end of a drilled hole. The enlarged hole, which is concentric with the original hole, is flat on the bottom. Counterboring is used primarily to set bolt heads and nuts below the workpiece surface.
Any manufacturing process in which metal is processed or machined such that the workpiece is given a new shape. Broadly defined, the term includes processes such as design and layout, heat-treating, material handling and inspection.
Machining vertical edges of workpieces having irregular contours; normally performed with an endmill in a vertical spindle on a milling machine or with a profiler, following a pattern. See mill, milling machine.
Workpiece is held in a chuck, mounted on a face plate or secured between centers and rotated while a cutting tool, normally a single-point tool, is fed into it along its periphery or across its end or face. Takes the form of straight turning (cutting along the periphery of the workpiece); taper turning (creating a taper); step turning (turning different-size diameters on the same work); chamfering (beveling an edge or shoulder); facing (cutting on an end); turning threads (usually external but can be internal); roughing (high-volume metal removal); and finishing (final light cuts). Performed on lathes, turning centers, chucking machines, automatic screw machines and similar machines.
