A REVOLUTIONARY CHARGING SYSTEM

Diamond Products is a leading specialist in the manufacture, assembly and sale of diamond tools and equipment for industrial applications. RAISING THE STANDARD contractors to achieve a wider and more evenly polished concrete and granite surface area. According to Diamond Products director Brian Clark, the triple head plan- etary polisher is designed to grind and polish granite, marble, engineered stone and concrete counter tops and stairs. “It utilises three 100 mm polishing or grinding pads, to achieve a perfectly flat and shiny surface,” he says. The Diamond Products triple head planetary polisher is capable of operating in wet or dry conditions, and comes standard with a dust extraction system. It is driven by a powerful 1 200 watt Makita variable speed grinder. Clark indicates that the variable speed control revolutions ensures optimal speed for diamond grinding and polishing in numerous applications. “This solution is ideal for refurbishing marble and granite table tops and floors, as well as worn staircases and landing areas,” he continues. The Diamond Products triple head planetary polisher has a grinding and polishing width of 200 mm. It is easily-ma- noeuvrable, as it weighs just 9 kg, while the Makita variable speed grinder weighs only 3 kg. The combined solution is also highly cost-effective. > The company launched its triple head planetary polisher at The Totally Concrete Expo to enable

Bosch kicked off the Wireless Charging System locally by

launching the GAL 1830 W charger and the GBA 18 V 2.0 Ah MW-B 18 volt lithium-ion battery onto the market. Bosch Power Tools SA senior brand manager Juergen Lauer explains that the Wireless Charging System is based on contactless energy transfer technology.

tools in that class. “What’s more, the excep- tionally robust charging stations no longer have contact points, and are therefore durable against water, dust and dirt.” The first components of the system Bosch will begin the new era of the Wireless Charging System with the GAL 1830 W Profes- sional charger and the GBA 18 V 2.0 Ah MW-B Professional battery. The GAL 1830 W Profes- sional is compact and currently the smallest charger available on the market for 18 volt lithium-ion batteries. As with the battery, it also features ‘Wireless Intelligence’ – an electronic system which ensures communication between charger and battery – which starts the charging process and adapts it to the current state of the battery. Lauer notes that this ensures that the battery is always optimally charged in every temperature range, in addition to having a longer lifespan. The Bosch GBA 18 V 2.0 Ah MW-B Profes- sional is a compact 18 volt battery which combines the advantages of the new tech- nology with those of the previous system. This 2.0 Ah battery has a charge level indicator and is equipped with the tried-

electric toothbrushes and cell phones, an alter- nating magnetic field is generated in the trans- mitter using a coil. The receiver also contains a coil which is penetrated by the alternating magnetic field. “This induces a voltage and generates a current flow,” he reveals. With the Bosch Wireless Charging System, this means that the charger emits a magnetic field which is received by the battery and trans- formed into charging current. However, the power transferred is more than 50 times greater than that used in ordinary electric toothbrushes (one watt), in order to reach the same charging times as those provided by conventional power tool battery chargers. Advantages Professional trade people who use cordless tools are mobile, but always have to schedule time and remember to charge the energy source. Semi-industrial applications, such as furni- ture manufacture, the electrical industry and vehicle construction, are particularly reliant on cordless tools. Lauer indicates that contactless energy transfer is especially beneficial in these stationary applications. “It is considerably more

cost-effective than conven- tional charging systems, as it eliminates the need for a second battery or expen- sive industrial charging stations. It also offers greater ease-of-use and productivity, as the batteries stay in the tool and can be parked on the charging station during every work interrup- tion to charge. The result is that the tools are always ready to be used,” he continues. According to Lauer, the Bosch Wireless Charging
