Horn USA has introduced its proven Supermini tool holder system with face clamping as a set, thereby responding to customer requests for different tooling system heights.
As a result of the design of the Supermini, clamping is not carried out via the lateral surface of the cutting insert but via a clamping wedge on the face. This results in a greater holding force on the insert and thus high rigidity of the entire system.

Blue Photon’s adhesive workholding solves problems associated with current workholding devices. The technology allows the user to hold parts and most materials without clamping. It also offers fixture design and engineering for milling, turning, grinding, electrical discharge machining (ECM), electro-chemical machining (EDM), 3D printing, laser, inspection, and assembly applications, including aerospace, additive, robotics, and medical machining.
Blue Photon Grip Pallets are designed to simplify how parts are loaded, reduce scrap and increase spindle uptime.
Available in 150, 225 and 300 mm square pallets, the Grip Pallets are designed for quick change and adhesive workholding of complex and hard-to-hold parts for EDM, grinding, inspection, laser and milling operations.
The pallets can hold parts securely, providing increased machining access on five to six surfaces while using standardized fixturing systems already in place.
Blue Photon’s grippers are inserted into new external inserts, designed specifically for the Grip Pallets. The external inserts are available for use with small, medium and large grippers. The new inserts allow for simple installation of the grippers at the required height for maximum holding power.
The 150-mm square pallet is available in aluminum and steel with a 52-mm pattern for a quick change receiver that will hold up to nine grippers. The 225-mm square pallet is available in aluminum and steel with a 96-mm pattern for a quick change receiver that will hold up to 21 grippers. The 300-mm square pallet is available in aluminum with a 96-mm pattern for a quick change receiver that will hold up to 33 grippers.
Each Grip Pallet includes two handles with multiple color choices and four spacers, with a 25.4-mm standoff that allows for the recommended nominal of 1-mm joint thickness between gripper and part.
Optional clamp studs are available for both 52 mm and 96 mm patterns for 5th axis, Jergens, Lang and Mate systems. Part can be removed with a ¼ turn twist of the gripper or hot-water soak. Residual adhesive is removed by using a handheld steamer or a hot-water soak and a light peeling action.

As seen at IMTS 2022. Dorian Tool’s Jet-StreamTM Thru Coolant Cutting Tools use a patented thru-coolant locking clamp which is precisely aimed to direct high pressure, high velocity coolant exactly onto the cutting edge of the carbide insert, from a short distance of 1⁄4”.
This controlled Jet-Stream coolant, directed onto the insert chip interface (right under the chip and over the insert cutting edge) will dissipate the generated heat very effectively as well as lubricate the cutting edge of the insert, causing the chips to hydroplane over the insert surface instead of adhering to it. As a result, the insert will operate at a constant low temperature, with a clean and undamaged cutting edge, changing the way metal is cut.
Higher speeds and feeds can be achieved, with a better surface finish, tolerance control and machining performance.
The insert life is extended up to 200%.
It's that time of year for IMTS!
Here's a preview of some of the products that are going to be featured during the International Manufacturing Technology Show September 12-17. You can see all of these new products and talk to the manufacturers in the Tooling & Workholding Systems Pavilion in the West Building Level 3.

Supermini Set. Horn USA is featuring the Supermini tool holder system with face clamping as a set, in response to customer requests for different tooling system heights. With this holder variant, clamping is not carried out via the lateral surface of the cutting insert but via a clamping wedge on the face. This results in a greater holding force on the insert and thus high rigidity of the entire system. This increases repeatability when changing the insert and provides better utilization of the available space. This is a big time saver on Swiss-type lathes, as the user can change the cutting insert without removing the tool holder.
New carbide grades for system DAH8 - Horn USA is expanding its range of carbide grades for its DAH milling system to enable its use for machining a wider range of materials. The new grades SC6A and IG6B complement the tool system for high-feed milling. The SC6A grade is suitable for machining the ISO M material group, as well as ISO S materials as a secondary application. Horn has developed the IG6B grade for machining the ISO P group, while it is also suitable as a multipurpose grade for other material groups.

At IMTS 2018, HORN USA presented two new developments in the area of whirling processes.
The JET Whirling System is the first whirling tool to feature an internal coolant supply. This whirling system offers optimized cooling directly at the cutting edge and was developed by HORN USA in conjunction with W&F Werkzeugtechnik.
Another innovation is the High-Speed Whirling Technology, which delivers high levels of productivity. In this process, the speeds have been specially adapted so that preturning and thread whirling can be carried out in parallel using a single work operation.
Through the JET Whirling process, HORN USA is demonstrating its expertise in the area of thread whirling. As part of a collaboration with W&F Werkzeugtechnik in Großbettlingen, experts from both companies have jointly developed a whirling system with an internal coolant supply.
By cooling the cutting edges directly, this system enables long tool life to be achieved. What’s more, when used in conjunction with the stable whirling unit, the system achieves better surface quality on the workpiece. Thanks to the patented W&F interface with its coordinated contact system for the tapered and planar surfaces, the whirling head boasts a high changeover accuracy and is easy to change with just three screws. The internal coolant supply reduces the risk of chip build-up between the cutting inserts.
It takes less than a minute to change the whirling head on the whirling unit interface. This interface offers a radial and axial run-out of 0.003 mm. The maximum speed is 8,000 rpm. The whirling heads are available with type S302 triple-edged indexable inserts or with type 271 double-edged inserts. The cutting edges are available with diameters of 6 mm, 9 mm and 12 mm. The interfaces for adapting the whirling unit are available for all standard Swiss-type lathes.
HORN USA is proud to present another new technique in the form of high-speed (HS) whirling. This technology is being exhibited in collaboration with machine manufacturer Index-Traub. High-Speed whirling boosts productivity significantly by performing the turning and whirling operations in parallel. With this technique, the speed is high enough for a turning process to be carried out prior to whirling.
The turning tool, which is located upstream of the whirling tool, reduces the volume of material that would otherwise have to be removed by the whirling tool. This enables longer tool life to be achieved and improves surface quality. The whirling heads are very similar to conventional ones. The only difference lies in the geometry of the cutting inserts. Single-start and multi-start threads can be produced using just one cutter unit.
Highly Productive Technique
Thread whirling is generally used in the production of bone screws. In this application, the whirling head rotates at high speed as it travels over the slowly rotating workpiece. The whirling head is set for the required lead angle of the screw. The workpiece is fed axially and as this happens the whirling tool cuts the thread.
Due to the high level of screw quality required, special attention must be paid to precision and surface quality when it comes to whirling tools. In addition, special materials are used for bone screws to ensure that the body is able to tolerate them when they are implanted. These include stainless steels, titanium, or cobalt-chromium alloys, although the disadvantage of these materials is that they are difficult to machine.
Therefore, expertise and experience are required if these materials are to be machined productively. For instance, the carbide substrates, coatings, and cutting edge geometries all have to be tailored to the application concerned.
HORN USA offers further whirling technologies in addition to its JET Whirling and High Speed Whirling solutions. Of these, the most universal technology is the standard whirling method. The whirling head can be connected to any whirling unit. For faster whirling head and insert changes outside of the machine, HORN USA has developed a modular whirling system.
Thanks to the precision interface, there is no need to readjust the whirling head once it has been removed from the machine. In addition, the spacer rings make it possible to adapt the whirling tool to different interfaces. With HORN USA Turbo-Whirling, high productivity is a sure thing. The cutting division between the roughing and finishing inserts reduces the load on the whirling tool’s profile cutting inserts. As a result, the system offers faster process times and lower tool costs.
