OTT-JAKOB Spanntechnik, a German manufacturer of tool clamping systems for lathes, milling machines and grinders, has launched a spindle clamping force measuring device, the Power-Check Micro. A key component for preventative maintenance, it has been introduced alongside the established Power-Check 2 and Power Check Magazine, which determine the pull-in force with which a tool holder is held in a large diameter spindle taper, whether it is HSK (up to 160), BT (30, 40 or 50), SK, CAT or another type.
In contrast, the Power-Check Micro is designed to perform an equivalent job for more compact HSK E15, E16 and E20 spindle interfaces, which are mainly found on small, precise machine tools intended for high-speed cutting. Such machining platforms are typically utilised in the dentistry and jewellery sectors, as well as for the production of small parts used in electronic and medical products, precision components in aerospace and automotive engineering, and small tools and dies.
These pull force measuring units are exclusively available in Britain and Ireland through sole sales agent Gewefa UK. The company points out that the new device is pertinent to nearly all micro-manufacturing applications, where there is a growing emphasis on process reliability, condition monitoring, preventative maintenance and quality assurance.
The latest drawbar force monitoring system is of compact design, measuring just 48.8 x 43 x 41.5 mm and weighing approximately 200 g, making the unit suitable for use in constrained working areas. Mains-independent, power arrives courtesy of two replaceable lithium batteries capable of up to 1000 hours of continuous operation.
