Distributor for NSK linear motion products

Over the past 45 years, NSK, one of the world’s largest manufacturers of linear motion and bearing technologies, has successfully served the Benelux market.

Supplying an extensive range of linear motion technologies – including linear guides, ball screws, monocarrier and support units – NSK has established an impressive client list in the medical, semiconductor and machining industries, among others. To enhance even further the level of support available to customers, NSK has decided to transfer the distributorship for its linear product portfolio to MCA linear motion robotics, which now becomes an NSK authorised distributor.

40xD drilling now available from Floyd

Now available in the UK from Floyd Automatic Tooling is the latest addition to the CrazyDrill range from Mikron Tool: the CrazyDrill Cool SST-Inox.

Small, deep and fast characterises the new drill, which incorporates internal coolant ducts and a novel geometry and coating for the machining of stainless steels, nickel-based super alloys, and CrCo alloys.
The range includes through-coolant drills in six different working lengths: 6xD, 10xD, 15xD, 20xD, 30xD and 40xD. For machining holes between 1 and 2 mm diameter, the maximum depth available is 20xD. However, from 2 to 6 mm diameter, the entire range can be offered. In addition, there is a short pilot drill for a maximum bore depth of 3xD.
Although drills with spiral coolant ducts are already available in small diameter ranges, many such tools get into trouble with tough-elastic materials or with the poor heat conductivity of super alloys. Here, cooling through conventional round ducts is insufficient, even with high pressure. Premature edge chipping and excessive chip accumulation are typical symptoms that prevent stable drilling.
A new geometry on the CrazyDrill Cool SST-Inox provides a chip-breaking effect at the front that results in short, curved chips, while at the back, an open-flute profile facilitates the evacuation of micro-chips. There is a variant for long drills as they incorporate an open profile and polished flutes to help the easy evacuation of chips from the bore.
Performance and process stability is mainly delivered by cooling the tool via two spiral internal coolant ducts up to the drill tip, while the ducts themselves have the largest possible diameter and are teardrop shaped.

Updated tool classifications from Dormer Pramet

Tooling specialist Dormer Pramet has upgraded the way it presents product data descriptions and workpiece material groups (WMGs) across its entire assortment of cutting tools.

The company is introducing standard tooling data, such as diameters and lengths, according to ISO 13399, allowing for easier and faster exchange of information between computer systems and software. ISO 13399 features a total of 133 parameters, covering a wide range of cutting tools, helping to support manufacturing planning, machining operations and product supply.
In supporting a common language in its descriptions, Dormer Pramet will save customers and partners a significant amount of time, offering easier data gathering across its 40,000 solid and indexable tools. In addition, the company is providing a greater level of detail than ever before on its WMGs. Helping customers to find the right tool for the application and supporting the machining process, this change is also based on the commonly used ISO standard. However, it is taken a step further as it includes recommended starting values for speed and feed.
Dormer Pramet now provides three levels of data for each of its products within the newly devised WMG structure. The WMG structure features the standard ISO material definitions, based on the six coloured groups, plus additional classifications on material structure, composition, hardness and ultimate tensile strength. The newly created standard and improved WMG data has been implemented in all of Dormer Pramet’s product material published from November 2019 onwards.

HP and Rösler in co-op

The recent Formnext exhibition in Germany saw HP, a specialist in 3D printing and digital manufacturing solutions, sign a co-operation agreement with AM Solutions, the brand name under which the Rösler 3D post processing and 3D printing services divisions offer products and services.

The two companies want to jointly improve the automatic post processing of components printed with HP’s Multi Jet Fusion technology. Parallel to the start of the co-operation, the 3D printing services division of AM Solutions is expanding its digital manufacturing capabilities with the installation of its own HP Jet Fusion 5200 series 3D printer.

Enhanced aluminium roughing for aerospace

The KOR 5 solid-carbide end mill is Kennametal’s latest innovation in high-velocity aluminium roughing. Designed for maximum productivity in aerospace machining, the use of this five-flute end mill means that table feed rates can be increased by up to 66% compared with common three-flute tools.

Kennametal’s KOR 5 is aimed at removing large amounts of metal and getting it away from the work zone as quickly as possible. Design features include a tapered core, variable pitch design and a 35° helix to help eliminate chatter and tool deflection. The through-coolant tool also has a novel chip-splitter pattern that is designed to break up long chips and eliminate re-cutting, but still contribute to high surface quality.
KOR 5 has more active contact points than a two-fluted or three-fluted end mill, chiefly because the five-fluted cutter creates improved stability and eliminates chatter on even the heaviest cuts. Applying the tool with low radial engagement, but high depth of cut, results in much higher metal removal rates than traditional methods. And to assure predictable, zero pull-out performance at maximum feed rates, the KOR 5 is available with Safe-Lock shanks.
Thilo Mueller, manager for solid-carbide end milling, says: “Slotting, deep pocketing, dynamic milling – whatever your aluminium application – KOR 5 can do it faster.”
