Kenner metal tools bring easy deep hole boring machining. Walking into any mechanical processing factory, you have the opportunity to experience such a scene: the high-frequency whistling sound generated by deep hole boring, the noise generated by vibrating the knife is unbearable, and we quickly put on earplugs. Machine operators have been plagued by this problem since lathe inventor Henry Maudslay first clamped a piece of steel material on a chuck and bored it, and it becomes more serious when the workpiece material is stronger and more difficult to machine.

But now the situation has changed. Kennametal's latest vibration-damping boring tool system to solve the vibration tool problem can allow machine tool operators in all processing plants to say,» I need it.» This new boring tool system uses Kennametal's most efficient anti-vibration device, and provides a variety of indexable tool head and tool shank sizes.

Into the field of anti-vibration performance

Sam Eichelberger, a turning product development engineer, knows this very well and is also a member of the in-house vibration damping device development team.» The most important feature about this new boring bar product is its plug-and-play performance,» he said.» There is no need to make any adjustments-you just open the product package, install it on the turret, and start boring.»

Kennametal's new vibration-proof boring tool system uses a variety of improved technologies to achieve plug-and-play performance. A variety of replaceable bits are available, including threaded interface types and lever clamping types, with positive and negative rake angle configurations.

But more importantly, it can make the processing plant a quiet place to work. Avoiding the appearance of vibrating knives can significantly extend the service life of the tool, not to mention its positive effect on the surface accuracy of the workpiece. When the tool is used for a longer time, greater cutting force, higher feed rate and cutting speed, and greater depth of cut that many industry experts previously thought could not be achieved can be used.

Eichelberger is one of those experts. He listed some of the characteristics of this product, it is these characteristics make this anti-vibration boring bar product is easy to use, but also very efficient products. These features include a toothed, bolt-on interface design at the working end of the boring bar, which provides a secure grip on a wide variety of indexable boring head types and sizes.

Even better, these boring heads themselves are also designed in a simple way, with shorter length and lighter weight, which can provide better stability and ensure better performance of boring bar products. These products also have internal cooling performance, which can accurately direct high-pressure coolant to the areas where the coolant is most needed. This ensures convenient chip control and optimal cooling of the cutting site.

The most important point is its internal damping device. Eichelberger said,» This boring bar product has both anti-vibration performance and maintenance-free performance. Inside the boring bar there is a centroid block supported by a pair of elastic support devices, which is filled with damping fluid. The centroid block vibrates at a predetermined frequency during processing, which weakens the natural frequency vibration of the boring bar, thereby achieving the damping performance of the boring bar. No need to worry about the wear of the parts, and no need to worry about adjusting the settings-as Sam mentioned, you only need to install it, and then don't worry about the rest.»

The anti-vibration boring bar has excellent performance in deep hole boring processing up to 10XD aspect ratio. Eichelberger explained that this product is much better than the deep hole boring performance of solid carbide or heavy metal boring bars. Internal and customer tests have shown that the surface finish performance of this product is comparable or in most cases better than the competitor's» Quiet boring bar» products, while more aggressive cutting parameters can be used in a variety of applications.

Of course, the performance of the boring bar is closely related to its clamping method on the machine tool. Kennametal has solved this critical problem by providing tool holders that match the machine tool turrets and special reducer sleeves.» That's the purpose of this product, says John Gable, Global Product Manager at Kennametal.» This is a product with the best stability and vibration reduction.»

All machine operators who have experienced the confusion of how to adjust the center height will be satisfied with the ease of installation of this product.» There is a reference plane at the location of the cutter head where the visual angle gauge is installed,»Eichelberger indicate.» All you have to do is turn the bar until the angle returns to zero and then hold it firmly.»

Considering the high cost of such a boring system, users will also be very satisfied with its replaceable head design, because it can be replaced in the event of head breakage without damaging the boring bar itself. Users of Kennametal's old boring system will find that these new cutter heads can be well matched when using joints.

» Our inch boring bar series diameter sizes range from one inch to four inches, and the metric boring bar system diameter sizes range from 25 mm to 100mm,»Gable said.» There are also many types of replaceable bits, from the positive rake angle insert type of threaded interface for super finishing to the negative rake angle clamping groove insert type for heavy roughing. This boring bar product is designed to have leading performance in harsh working conditions, which is the characteristic of this product.»
