Gasbarre delivers 750 ton multi-action press Gasbarre Press Group has installed a 750 ton multiaction powder compaction press to compact complex multi-level parts for automotive and lawn and garden industries. Gasbarre’s machine features three floating lower levels with selective ejection, a floating die platen, and a pneumatic dual upper punch system with top punch hold down. Each level of the press is independently controlled
and is displayed digitally for easier adjustment and precise control. The stationary platen includes 1-1/2 in of motion with adjustable counterforce for powder transfer. The core rod is hydraulically driven for enhanced controllability and increased stripping force. The press includes a servo-controlled filler shoe system giving precise function control through a touch-screen operator interface.
The press can compact parts for garden accessories.
Bearings incorporating wireless technology SKF has launched SKF Insight, wireless technology that can be integrated into SKF bearings. The technology allows the bearings to communicate their operating conditions continuously, using an integrated, self-powered package containing sensors and data acquisition electronics. The technology can sense RPM, temperature, velocity, vibration, load and other features.
“These innovations are set to revolutionise condition monitoring for bearings, especially in critical machinery and technically challenging applications,” said Tom Johnstone, SKF president and CEO. The technology has taken three years to develop following extensive R&D work. Previously, condition monitoring techniques could only monitor damage after it has
Self-sharpening saw tip improves efficiencies Ceratizit has developed CTDIA02, a carbide saw tip with a layer structure that enables it to self-sharpen and ensure high surface quality on the workpiece, even at a cutting performance of 250 km. The various layers allow the cutting edge radius to remain the same during the entire sawing operation. This is possible thanks to the self-sharpening effect. In this way, the cutting edge is not honed but only slightly changes its position, remain-

ing consistently sharp. In one example, cutting an MDF particle board, the saw tip cut 250 km, surpassing the performance of conventional equivalents. The special layer structure also protects the PCD against edgechipping. This, together with the consistent edge radius, provides a uniform quality of the cut workpiece surface even when the cutting length is increased. Compared to high-quality carbide saw tips, operation costs are even reduced by around 60%.
occurred. Now, SKF says that it can monitor bearing damage from the first microscopic effect as it is happening, and with this information, customers can take remedial action to reduce the reason for damage in the bearing – adding lubricant, mitigating transient overloads, etc. In addition, by monitoring the load directly on the bearing, SKF Insight makes it possible to measure the load
the bearing actually experiences rather than what is was designed for. This valuable information can be routed back into the design phase to improve both the system and bearing design. The bearings can communicate through each other and via a wireless gateway, forming a “mesh network.” SKF Insight is currently under trial with customers in the energy, railway and metals markets.
Non-ferrous roughing tool for better chip management SGS Tool Company, a manufacturer of round solid carbide cutting tool technologies, has added a new series of roughing end mills to its S-Carb product line. The new series 43 Chip Breaker encourages load reduction and offers improved chip management during aggressive aluminium and non-ferrous machining. The flute shape facilitates the rapid movement of the large volume of chips created during aggressive machining.
The ‘tombstone’ cam cap component.
The chip breaker disrupts the chip flow along the cutting edge, resulting in smaller and more controlled chips, while preventing builtup edge and reduced power consumption.
