HEAVY ROUGHING MADE LIGHTER From our overseas file comes the launch of Pramet’s chip breaker and grade for heavy roughing applications. The HR2 geometry expands Pramet’s range of single-sided inserts for machining a wide range of materials including steels, cast irons and stainless steel. Designed for rough forgings and castings, such as cylinders, shafts and large pins, the HR2 features a positive, stable geometry for improved tool life and performance. Its cutting edge design and wide peripheral land promote increased productivity, while offering reliable chip formation and evacuation at high feeds (0.7 mm/rev). This promotes a continuous production process with less machine downtime, resulting in a more cost-effective operation. The new chip breaker compliments the existing HR insert which covers semi-roughing to roughing applications. HR2 is available with a new turning grade – T9226. The versatile T9226 grade achieves impressive results in heavy roughing and peeling operations. For these applications it replaces Pramet’s existing 6630 grade. Providing high insert reliability and durability in adverse cutting conditions, the T9226 offers greater cutting edge strength. This is primarily due to a new functional gradient substrate which contains a higher amount of cobalt binding and finer grain structure. A special treatment added to the coating’s surface promotes reduced adhesion to the workpiece and resistance to the formation of heat-related cracks, resulting in greater operational reliability and longer tool life. In a recent example, machining P4 steel without coolant and in an interrupted cut operation, the T9226 grade lasted for 52 minutes, compared to a competitor grade which operated for just 25 minutes (cutting speed 55m per min, feed 0.8 mm/rev and 8mm axial depth of cut). www.dormerpramet.com MATHWORKS DOES THE WORK FOR YOU MathWorks has announced capabilities to strengthen design support for digitally-assisted RF MIMO Systems. Updates to RF Toolbox, SimRF, and Antenna Toolbox in Release 2016a, will help engineers ramp-up on RF simulation, assist in performing a first order RF budget analysis that is extendable with advanced models, and help integrate the results of RF design in system-level simulation. The introduction of RF Budget Analyzer in RF Toolbox helps engineers design RF front ends, focusing on getting started with RF modelling and simulation. This helps teams efficiently iterate between system-level specifications and implementation of architectural designs, and reduces time spent in debugging validation test benches. Engineers can now rapidly build executable specifications of the RF front-end and integrate the results of RF design into a system-level simulation. This allows for help with validation of behavior and, by facilitating sharing, supports collaboration with colleagues, suppliers, and customers. mathworks.com PRECISE WIRELESS POSITIONING A wireless-controlled hydraulic load hoisting and positioning system being introduced by Enerpac Australasia enables a single crane to precisely position heavy and unbalanced loads weighing hundreds of tonnes. The SHAS series synchronous hoist system – the latest in a growing range of SyncHoist systems developed by Enerpac for diverse industries – is a below-the-hook crane attachment operated by a single wireless controller to provide accurate, safe and cost-effective positioning of such loads without the need for multiple cranes. SHAS comprises four, double acting, push-pull cylinders connected to lifting points above the load by cables or under an optional auxiliary frame enabling accurate hoisting where space is limited. The lifting cylinders are available with 110 and 225 ton lifting capacities each, plunger strokes of 1 and 1.5 metres and capable of high precision lifting accuracy of +/- 1 mm over the full stroke. www.enerpac.com
