Sandvik Coromant recently presented the extension of is exchangeable-head system. It offers greater flexibility from new heads, cutters and integrated tool holders with exchangeable head coupling
This fall see the expansion of Sandvik Coromant’s exchangeable-head (EH) system to include a wide assortment of solid carbide heads, indexable milling cutters, boring heads, integrated machine adaptors and different shanks.
The exchangeable head coupling is based on a self-centering screw thread for secure mounting and maximum strength and security. The coupling has a physical stop which makes it easy to feel when the head is correctly tightened and helps to not overstress the clamping. The conical portion is shaped to provide best run-out. Pre-loaded taper and flange contacts provide an optimized modular connection with extreme rigidity and strength.
These new extensions meet the requirements for long reach in large machining centres in the diameter range of 10–32 mm (0.394–1.26 inch) for milling and 1–36 mm and (0.039–1.42 inch) for boring.
The 5th Micronarc Alpine Meeting (mAm) will take place in Villard-sur-Ollon from January 19 to 21. The program is almost complete and registration is now open. A special earlybird registration fee is available – but only until December 18.
Following in the success of the first four editions, The Micronarc Alpine Meeting 2014 will continue its focus on equipment for manufacturing microproducts. This 2 day conference intends to stimulate networking and discussions in the casual atmosphere of Villars, a charming village and ski resort located at 1250 meters of altitude. A selection of invited speakers and presentations will comprise the program. A small, table-top exhibition will be conducted in parallel for those wishing to promote their company and products.
The conference will take place on a Monday and Tuesday, thus permitting participants that wish to arrive early to take advantage of the proximity to the ski lifts or simply relax for a couple of days in a laid-back alpine setting. A conference dinner on Monday evening at 1800 meters of altitude will add a touch of local charm.

After the EMO and the positive welcome of the new products in Hannover, the company will present them to the Swiss market during an open-house exhibition to take place in its headquarter in Moutier.
The EvoDeco offers a remarkable design and boasts surprising power both for spindle and counter spindle machining. We decided to focus a bit more closely on this powerhouse by studying the machined part.
EvoDeco 32 – The most powerful machine on the market
Simple in appearance, the part is made from grade 303 stainless steel, and is machined from a 32 mm bar. To realise it, the machine must make a long drill hole of 150 mm, but also narrow the outer diameter from 32 mm to 22 mm over a length of 90 mm. Tapping, flat milling and drilling are all part of the process. “The part is not dissimilar to one made by our customers from the same material; it is subject to very stringent controls in terms of dimensions. Furthermore, we wanted to adhere to market requirements; we need to work at speed and remain accurate”, reveals Arnaud Lienhart, EvoDeco 32 project manager at Tornos.
EvoDeco 32 – Fully equipped for every challenge
The machine has comprehensive basic equipment and benefits from a whole host of extra equipment developed for the Deco range, which gives it almost limitless flexibility. Mr Lienhart concludes: “To get an idea of the power of the EvoDeco 32, I would recommend that you watch the part being machined on the YouTube platform. For the purposes of the film, the part is made from brass, but our specialists would welcome the opportunity to demonstrate the power of the EvoDeco32 to you on harder materials”. http://www.youtube.com/watch?v=huUg5S35gFk
Several Swiss premieres not to be missed
From December 4 to 6, 9 a.m. to 6 p.m. visitors will be able to discover the new highlights of the product range of the Swiss Manufacturer:
Delcam has launched the 2014 release of its Delcam for SolidWorks integrated CAM system, the first version to include the Vortex strategy for area clearance. The software also includes a number of new options for turning, four-axis rotary machining and turn-mill operations, plus more strategies for two-axis finishing.
Vortex (www.vortexmachining.com), for which Delcam has a patent pending, has been developed specifically to gain the most efficient material removal from solid carbide tooling, in particular those designs that can give deeper cuts by using the full flute length as the cutting surface. It can be used for two- and three-axis roughing, three-plus-two-axis area clearance and for rest machining based on stock models or reference toolpaths.
Optimum cutting conditions
Unlike other high-speed roughing techniques that aim to maintain a constant theoretical metal-removal rate, the Vortex strategy produces toolpaths with a controlled engagement angle for the complete operation. This maintains the optimum cutting conditions for the entire toolpath that would normally be possible only for the straight-line moves. As a result, the cutting time will be shorter, while cutting will be undertaken at a more consistent volume-removal rate and feed rate, so protecting the machine.
The ability to add fillets to any sharp corners has been added; for example, for automatic deburring, without having to edit the geometry. The user simply has to specify the radius to be applied and all the sharp corners will be filleted automatically.
Turning simulation has been made more realistic with the ability to program and simulate the movements of the steady-rest that can be used to position large parts during turning and the tailstock that can be used to hold long parts on centre during machining. Collision detection against both these types of accessory is undertaken automatically.
Improved support for machines with four-axis rotary tables allows two- or three-axis operations to be wrapped around the rotary axis.
And much more with editing toolpaths and extra strategies for two-axis finishing, more efficient machining and safe programming.
With its EcoCCore system now superseding the previous 81C/P equipment series, Dürr Ecoclean is setting new standards in solvent-based part cleaning. This is due to a one-third increase in product throughput and load weight which yields a marked reduction of per-unit cleaning cost.
Moreover the new machines are equipped for improved cleaning performance, superior process reliability and significant energy savings. Designed to use non-halogenated hydrocarbons and modified alcohols, the EcoCCore also boasts superior ease of operation, less space demand and a translucent design.
Innovative technology for optimized cleaning quality
A major step towards improved cleaning quality lies in the new preliminary steam degreasing process. Here the oil-containing distillate is not passed into the flood tank as usual but is directed straight into the distilling system. This minimizes oil deposits in the flood tank and an undesirable oil enrichment of the solvent. The result is an enhanced degreasing performance that will be found particularly beneficial with parts to be coated or laser-welded after cleaning.
High process reliability thanks to ease of operation
Operating the EcoCCore machine is made simple, fast and safe by the new 7″ color display based on self-explanatory pictographs. Process tracking and maintenance, are rendered intuitive and more convenient by the integrated part visualization system. An optional full visualization capability can be integrated above the control panel.
Smart and attractive machine design
The design of this equipment, honoured with the 2013 Design Award of the state of Baden-Wuerttemberg, is striking not least due to the integral loading system and its all-round enclosure made of safety glass. Moreover, the universal EcoCCore machine requires around 5 percent less floor space than its 81C/P predecessor.
The mechatronic Schunk EGP 25-speed gripper for small components is the smallest electric gripper with integrated electronics on the market, and even more convincing it also has the best stroke to closing time ratio.
With a maximum stroke of 3 mm, it only takes 0.03 s for its fingers to close, thus offering optimal prerequisites for minimal cycle times. The tiny, power dense gripper weighs just 100 g and has a gripping force of 7 N. It is suitable for rapid handling of workpieces up to 35 g in friction-fit clamping.
Wear and maintenance-free
Brushless and thus wear- and maintenance-free servomotors as well as a powerful junction roller guide guarantee a high level of efficiency and make the gripper into a dynamic and high-performance expert for demanding pick & place applications. Since it is based on the platform of the tried and tested pneumatic Schunk MPG-plus gripper for small components, it comes with a bundle of additional advantages. In many cases, users can transfer the sensor systems used in the Schunk MPG-plus to the Schunk EGP-Speed, and easily convert existing systems from pneumatic to electrical operation.
Control of the Schunk MPG-plus can be analog, digital direct, or via a sensor distributor. Just like the Schunk MPG-plus, the Schunk EGP-Speed takes screws on the side or at the base, which increases its flexibility within a system design. In order to increase the dynamics and the energy efficiency of higher-level systems, the gripper housing consists of a special high-performance aluminum. In addition, the design is rigorous in eliminating superfluous materials. The electronics are built in the interior to save space. The pick & place expert fulfills protection class IP30 and fits seamlessly in the program for modular high performance assembly from Schunk.
Gibbs and Associates, developer of GibbsCAM® software for programming CNC machine tools and a Cimatron company, today announced availability of its new 5-Axis Porting option for GibbsCAM.
The new software provides a specialized interface optimized for the machining processes and cutting tool motion required to machine tubular openings that change shape and curvature from one end to the other. The Porting option complements GibbsCAM 5-Axis by enabling easier and faster programming of port-like openings through a condensed interface that provides toolpath options and machining strategies optimized for machining such open shapes. Designed to accommodate the motorsports industry, where engine performance is frequently increased by optimizing flow through ports, manifolds and throttle bodies with specialized machining, the 5-Axis Porting option can increase the efficiency of programming and machining any parts with openings that change profile and curvature from end to end.
Features of GibbsCAM 5-Axis Porting Option
The software can automatically detect the spine curve through the port and properly align the toolpath. Using available tool reach, the software can split upper and lower operations automatically by maximum tool reach, midpoint or user selected percent of reach, ensuring proper toolpath blending between upper and lower sections. Machining strategies include roughing, rest roughing, and spiral and plunge (along) finishing. To maintain tool rigidity, 5-Axis Porting maintains 3-axis machining (3 + 2 mode) as far into the port as possible until 5-axis simultaneous motion is required. Tool tilting is automatically calculated for optimal angles, without the need to split surfaces or create tool axis control splines, producing smooth, gouge free 5-axis motion. Users may choose to machine only the top of a port, only the bottom, or both sides, in a single operation.
In addition to ease and speed, the GibbsCAM 5-Axis Porting option generates a cleaner, more efficient toolpath for faster machining and higher quality parts.
