The impact of the financial crisis has brought down the demand for the tool market, but for big-name manufacturers such as Kenner and Sandvik Coromant, the sluggish demand does not seem to affect their steady development. Such a deep anti-crisis ability is naturally cultivated by many factors. The most important thing to ignore is the superior technical background and unique technical know-how.
In this article, we will focus on the progress and characteristics of several companies in the field of turning.
Kennametal
Kennametal has introduced the Beyond range, a complete line of new high performance turning products, including 11 materials. Thanks to its high material removal rate and long tool life, “Customers can use Beyond tools to select a wide range of cutting parameters while increasing tool life and increasing productivityâ€. Ujjwal (UJ) Baid, senior product manager at Kenner, said: "After this technology, field trials in many places have shown that production efficiency can be increased by 30% to 300%." ​​For example, KCP40, a type used for steel parts Processing the new Beyond material, the cutting speed and depth of cut in the test increased by 10% to 20% compared to its competitors.
“We investigated a wide range of materials and applications,†said Chuck McNerny, global product development manager at Kennametal. “Each category is specifically optimized for substrate characteristics and coating thickness depending on its application. Compared to previous products, it has increased production efficiency and expanded the range of applications."
All Beyond inserts are coated with CVD (Chemical Vapor Deposition), but CVD coatings tend to cause residual tensile stress. Beyond inserts have a post-coating finish on all surfaces to reduce tensile stress, which improves coating adhesion and reduces microcracking. “The cutting edge wear is more even and stable, which improves tool life and is more stable,†said Kent Mizgalski, Kenna Metal Global Lathe Systems Engineering Manager. “Another factor in improving the Beyond range of tool applications and using higher cutting speeds is that the smooth surface reduces friction. Together with the correct geometry, we have both chip control and tool life in both laboratory and in-situ machining. There has been a lot of progress."
Kennametal is recognized by APQC as one of the top five best practice partners for improving and improving the front-end efficiency of new products and innovative services
According to reports, on December 22, 2008, Kennametal announced that it has been rated by the US Productivity and Quality Center APQC as one of the five best practice partners to improve and improve the front-end efficiency of new products and innovative services. The latter is a non-profit organization that is an internationally recognized leader in benchmarking, knowledge management, measurement and quality programs. In a survey of companies that have been successful in developing new products in the United States, Kennametal's ACE (competing competitive advantage) world-class product development process and best practices in the early stages of innovation are fully recognized. In fact, this is the fifth time Kenner has won the organization's award.
Sandvik Coromant
ChristerRicht from Sandvik Coromant said that in order to process heat-resistant superalloys with relatively high production efficiency, the corresponding processing strategy must be carefully prepared. Since at least 50% of the processes for machining such parts are turned, the basic principle should be based on the appropriate cutting edge cutting method.
For example, in many cases, Xcel inserts are the best choice for semi-rough/finishing operations. This type of blade combines the advantages of a small main angle of the square insert with the strength of the cutting edge and the flexibility of the diamond insert in the direction of the cutting. It is especially advantageous to use a Xcel blade rough step.
The 4Xcel insert is an innovation that takes the turning of heat-resistant superalloys to new levels of performance, with advantages including better tool accessibility, slowing groove wear, reduced radial cutting forces and constant chip thickness.
Heat-resistant superalloys (HRSA) have some unique properties, such as excellent high temperature strength, good toughness and corrosion resistance, making them a steam turbine, jet engine, chemical and food equipment, medical devices, etc. The only choice for these parts. But these attributes, combined with their extremely poor machinability, also mean that their machining is quite difficult – especially when high efficiency is required. ChristerRicht recommends that the blade should be cut with a relatively small lead angle (45 degrees or less).
