At this year’s EMO exhibition in Hanover this September, Schwäbische Werkzeugmaschinen (SW) is presenting the new Sfix system (Smart Fixture). Sfix is capable of automatically assembling modular clamping fixtures for workpieces, enabling efficient and precise clamping even for small batch sizes.

“Especially outside the automotive industry, we see great potential for optimisation in medium- and small-series production, which requires greater flexibility and modularity from manufacturers,” says Michael Kreuzberger, product manager at SW. “To address this, our new Sfix system transforms clamping technology: through automation, it enables higher productivity even in production lines with smaller batch sizes.”

The Sfix system offers a solution to one of the machining industry’s biggest time wasters: the clamping of small- to medium-sized product series. Sfix provides a flexible solution to this challenge: it automates the assembly of the appropriate clamping technology for each workpiece – and provides users with a virtually unlimited number of clamping fixtures for a one-time investment. At the core of the system is SW’s patented Sfix plate, which features retractable pins that allow for flexible positioning of components. Various clamping modules can then be attached to these pins to build the individually required fixture.

The advantages of the Sfix system extend beyond its modular mechanical design: in the so-called S-cell, which SW is presenting at its EMO booth, the clamping fixture is assembled quickly and fully automatically. The cell is equipped with all necessary clamping components and workpiece carriers as well as a robot. Users only need to define the clamping points within the CAD model and configure the fixture set up.

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.
