Kennametal announces breakthrough spindle connection

Spindle connection helps deliver maximum machine tool power for maximum metal removal in titanium and hard alloys. The spindle connection is the interface between the machine tool’s spindle and toolholder. As such, this vital component has to provide the torque and bending load capacity compatible with the machine-tool’s operating specifications.

Kennametal’s robust KM4X100™ spindle connection provides three times greater bending moment resistance for improved milling, turning, and holemaking.
Kennametal’s robust KM4X100™ spindle connection provides three times greater bending moment resistance for improved milling, turning, and holemaking.

When machining high-strength materials like titanium and other alloys, cutting forces generate bending moments that may exceed the interface’s limits prior to reaching the machine tool’s torque threshold. By combining high clamping force and optimized interference levels, Kennametal’s new KM4X100™ provides a robust connection, extremely high stiffness, and bending load capacity for greatly improved performance in machining high-strength alloys and other materials.

To use machines at full capacity
“In most cases, the tool-spindle connection determines how much material can be removed on a given operation,” says Doug Ewald, director, global product management, tooling systems at Kennametal. “This is because this interface must withstand high loads and yet maintain its rigidity. With the ongoing advances in cutting tools and machining centers, a spindle connection like KM4X 100™ that makes the best utilization of available power possible is an important consideration to investigate early in production planning.”

A few assets
By using three-surface contact for improved stability and optimized clamping force distribution and interference fit, KM4X100™’s engineering results in three times the bending moment resistant capacity compared to other tool systems. This means:

  • Shops can leverage KM4X-equipped high-performance machine tools to increase speeds and feeds in difficult machining applications, thus gaining the full productivity potential from the machine tool.
  • Often, a smaller KM4X connection such as a KM4X100™ will provide the same or better cutting performance of a larger connection.
  • KM4X systems can be applied on multi-tasking, turning, machining centers and transfer machines in manual, semiautomatic, or fully automatic mode.

Ceramic insert delivers productivity boost in cast iron milling

CC6190, a new ceramic insert grade for CoroMill 490, promises 2-3 times greater productivity against cemented carbide insert grades in cast iron and hardened steel due to the potential for higher cutting speeds.
Sandvik_Ceramic
Any manufacturer involved in automotive part machining or general engineering will benefit from the use of CoroMill 490 with CC6190 ceramic inserts. A superior performance and enhanced precision are assured in applications that include the milling of engine components such as valve bodies, crankshafts and gearbox housings.

2-3 times higher productivity
Designed and manufactured by Sandvik Coromant, CC6190 offers 2-3 times higher productivity than cemented carbide grades, while the insert design with parallel land delivers exceptional surface quality. It is aimed at the medium-to-light roughing of grey cast iron components, as well as nodular cast iron and compacted graphite iron (CGI) parts.

Improved tool life
In finishing trials on a valve body made from SS0125 cast iron, quality requirements included a surface finish of 1.0 Ra and flatness of 0.03 mm. At identical cutting data, CoroMill 490 with CC6190 inserts achieved 40% greater tool life over a comparable competitor tool. Similarly, another test showed a 20% boost in tool life when roughing a workpiece manufactured from GG25 grey cast iron.

The considerable potential of high-precision micro-machining

At a time when it is possible to manufacture tools with a diameter of 0.02 mm which are not only reserved for niche sectors, high-precision machining of the smallest parts is more than ever the key to innovation in electronics or in medical engineering. Leading experts in micro-machining met to discuss requirements to which each link in the value production chain is subject.

The circle of experts (from left): Roland Gerlach, Sales Director at Schaublin, Martin Ruck, Product Developer at Zecha, Arndt Fielen, Sales Director at Zecha, Jörg Schwartz, Director of Schwartz Tools and more, Hans-Joachim Günther, Product Manager at Tornos, and Michael Urnauer, Key Account Manager at Hommel+Keller Präzisionswerkzeuge.

High-precision machining of exotic materials, including in the smallest diameters, without losing sight of the issue of profitability, does not depend on a single factor for its success. On the contrary, it is the harmonious interaction between the machining centre, the tool mounting system and the tool itself that enables the supplier to satisfy the requirements of the customers. And optimum results are achieved when the specialists in the field come together to address the vital questions and challenges of micro-machining, with a view to constant improvement of the overall concept.

Expertise network
Together, Schaublin GmbH – which manufactures high-precision turning centres and clamping devices, Schwartz Tools and more – an expert in turning tools, as well as Zecha Hartmetall-Werkzeugfabrikation GmbH – on the strength of nearly 50 years of tradition in the development of tools for micro-machining, constitute a genuine expertise network in micro-machining. They have all long since established themselves as trustworthy contacts through the various trade fairs in the world of small-size parts. Other companies are also involved, in particular during the seminars, such as Hommel+Keller Präzisionswerkzeuge GmbH, the world leader in knurling tools, and the Swiss company Tornos S.A., which manufactures single- and multi-spindle turning machines, as well as machining centres for highly complex precision parts. As Arndt Fielen, Sales Director of Zecha Hartmetall-Werkzeugfabrikation GmbH, explains: “Dialogue with the manufacturers enables us to build up a unique wealth of knowledge, so that together we can cover the complete range of micro-machining. For our respective customers, this results in optimised products, processes and services. Thanks to the active and productive exchanges that we have set up, we are able to resolve the most complex tasks.”

Studer announces a revolution in thread grinding

Special grinding machines have previously been the first choice for technically complex external and internal threads with large pitches. This will now change with the introduction of an A-axis on the Studer S41 and S22 cylindrical grinding machines. Thanks to the new A-axis it will be possible to grind recirculating ball screws, thread gauges or thread rolls with large pitches perfectly in the future.

The new A-axis on Studer's S41 and S22 universal grinding machines is revolutionizing thread grinding on universal cylindrical grinding machines.
The new A-axis on Studer’s S41 and S22 universal grinding machines is revolutionizing thread grinding on universal cylindrical grinding machines.

Studer is revolutionizing thread grinding on cylindrical grinding machines with the new A-axis on the Studer S41 and S22 cylindrical grinding machines. Whereas users previously had to take recourse to high-investment special grinding machines in order to grind recirculating ball screws or worms for example, these can now be ground on the Studer S41 and S22 grinding machines. This is made possible by a newly integrated A-axis, which has been available as an option since September 2013. This is a big step towards efficient complete machining in a single clamping.

Not new – just different
Thread grinding on Studer grinding machines is not new. The Thun grinding machine manufacturer has been proficient in this process since 1997 and has perfected it in recent years. The difference in the new process with A-axis: Studer previously used axis-parallel thread grinding processes. Around 75 percent of all desired thread types can be covered with this process, but for the remaining 25 percent a tilting grinding wheel (A-axis), adapted to the thread pitch angle, is necessary.

Decisive advantage
Erhard Kämpf, Head of Form and Thread Grinding highlights the advantages of universal machines: “The decisive advantage over special machines is that these are universal cylindrical grinding machines. Not only can they perform thread grinding perfectly, but they can also – depending on the grinding head variant (S41) – perform complete machining operations. In other words, the workpieces are completely manufactured in a single clamping. This means that in most cases the process is more precise on the one hand, and quicker on the other.”

Two A-axes for the S41
Productivity is the catchword when it comes to cost effectiveness. The S41 scores double points here: It can even be equipped with two A-axes. A huge advantage for high-productivity applications: one grinding wheel can be used for rough grinding (from solid) and the second can be used for fine grinding.

Threads which could previously only be produced with special grinding machines can now be ground on the Studer S22 and S41.
