With its X•treme Evo Plus drill, Walter is launching a new tool in the DC180 Supreme product range. Krato•tec coating technology for drilling and reaming tools now extends the market potential of these solid-carbide drills. This is credit to the WJ30EZ grade – developed in-house at Walter – with an AlTiN multi-layer coating that enables the drills to reach high cutting speeds. It also makes the drill suitable for universal use in all ISO materials from groups P, M, K, N, S and H.

When compared with alternative products, the DC180 Supreme has a tool life that is up to 50% longer, reports Walter. The drill with internal coolant channels is for use with emulsions, oil and MQL. Its geometry incorporates a straight cutting edge that gives it a high level of stability and process reliability. Walter offers the DC180 Supreme with a diameter from 3 to 20mm for a diverse range of applications.

As standard, Walter is introducing the DC180 Supreme in dimensions of 3xD in accordance with DIN 6537 short and also 5xD following DIN 6537 long to its range. The tool specialist can also offer special tools with intermediate sizes and step drills upon request with short delivery times via its Walter Xpress service.

Walter Xtreme Evo Plus drills from the DC180 range are part of the Supreme product line for large-quantity production runs and heavy-duty drilling operations. Thanks to its long tool life, high productivity and high wear resistance in demanding applications, Walter says that the DC180 Supreme reduces costs and is suitable for difficult machining operations.

Kyocera Corporation is introducing new CVD coating materials, CA115P and CA125P, for turning insert grades used in automotive and industrial steel machining. The new coating technologies achieve a high level of wear and fracture resistance, resulting in a long tool life. In addition, Kyocera is launching a PMG chip breaker, which covers a range of machining applications, along with the new insert grades.

The new CA115P and CA125P insert grades – the main grades for external and internal turning for steel machining – have a newly developed coating and carbide substrate. According to Kyocera, the coating achieves the industry’s highest level of uniformity in alumina crystal orientation through the company’s proprietary crystal-forming technology during the CVD process, which helps to ensure outstanding wear resistance.

By combining this ultra-uniform alumina layer with a proprietary TiCN layer and new carbide substrate offering greater high-temperature strength, the insert grades achieve higher wear resistance and fracture resistance, as well as long tool life and stable machining. In addition, the PMG chip breaker supports various machining conditions, from medium machining to roughing, making it possible to consolidate tools and deliver productivity improvements.

CA125P grades support a wide range of machining conditions, from continuous to heavy interrupted machining, and are highly versatile main grades. CA115P grades are for high-efficiency machining in continuous to light-interrupted machining, contributing to productivity improvement through long tool life and stable machining.

Kyocera’s new PMG chip breaker achieves smooth chip evacuation in medium roughing. In addition, the low-cutting-force design of the cutting edge suppresses crater wear on the rake face, which enables lasting chip evacuation.

Groove, cut-off and gear milling are just three processes that the circular interpolation milling system from Horn now performs even more productively following the introduction of a range of tools with nine cutting edges. The system can be used from an inside diameter of 8 mm for the precise boring of grooves down to 0.25 mm wide, or for milling splines. Standard tools and special variants are available.

Smaller diameter circular interpolation mills from Horn were previously available with exchangeable heads having a maximum of six teeth. Three extra cutting edges offer higher material removal rates, raising productivity by shortening cycles and, at the same time, extending tool life. In addition, the cutters run more quietly and with less vibration compared with tools having fewer teeth. Consequently, the dimensional accuracy and surface finish of components see improvements.

Horn stocks the nine-edged milling systems M911, M913 and M928 in widths from 1.5 to 3 mm. Maximum milling depths are 3.5, 4.5 and 6.5 mm respectively. The cutter heads are available with different coatings to suit the material in cut. Due to its mass, the solid-carbide tool shank ensures vibration damping during milling. Horn designed all variants of the shank for internal coolant supply.

Business has been growing so quickly for Italian medical implant manufacturer Permedica that it can barely keep up with demand. However, a new strategy for its CNC department, in partnership with Seco Tools, has started to make a notable increase to its productivity.

“One of our machines could not operate at night due to the programming and the kinds of tools we were using,” explains Permedica sales manager Federico Perego. “The material was overheating, which was stopping the machine and meant that it couldn’t be programmed to operate automatically during the night.”

He continues: “Seco were always very direct in relation to the issue and in proposing a better solution. They didn’t make a promise they couldn’t keep, and they didn’t just try to sell us tools. Instead, they helped us to solve what was an important issue.”

One of the Seco Tools Italy team working with Permedica, manufacturing transformation manager Matteo Foglietta, says: “We were able to address swarf issues that were a big problem for the night shift. So Permedica has gained not only more productivity in terms of a shorter cycle time, but also an increase in machine capacity during the unmanned nightshift. This is also thanks to the global competence from our innovation hub that we can bring to the customer side through local and technical expertise here in Italy.”

Perego estimates that this initial success has helped to increase Permedica’s productivity by more than 40%. Now further initiatives, including the installation of tool vending machines to help with warehouse management, are underway.

“So far, we’re very satisfied,” says Perego. “There are still headaches to solve, but I hope we can continue with this great start and achieve important things together because there is a lot of complexity in our business, and we need many resources to support this. Permedica is reacting to the help being provided by Seco by placing more orders for tools, so it’s a win-win relationship.”
