Driven tools form a further core area of EWS. More than 8,000 different tools are available at short notice. In addition to standard products like axial and angular heads, EWS offers swivel units, slot broaching tools, multiform tools and multi-spindle machines. There is just no limit. The tool clamping systems range from the classic collet chuck holder to Weldon and hydro extension to Capto, KM, ABS and HSK. The applications range from classic CNC lathes to highly complex turning milling centers. The rapid change system EWS-Varia has set a standard for a flexible modular system. With its safe handling and short change-over times, EWS-Varia ranks among the most successful systems in the market. This was impressively confirmed by the Innovation Award awarded by the German state of Baden-Württemberg in 2006. "Made in Germany" is of course guaranteed by EWS also for these tool systems.

Unloading machine Multi-3000 remove The Multi-3000 remove is an electro-pneumatically controlled automatic unloading machine. It is the ideal complement to the bar feeder Multi 3000 or the Multi 3000SL. With the Multi 3000 remove it is possible to unload finished parts from sub- or main spindle. The bars are unloaded by unloading tube, pneumatic gripper or also by collet chuck. After unloading, the bars are placed on a prism. From the prism the parts are transported to a deposit. A light barrier monitors the unloading process. The coating of the depositing surfaces enables a particularly gentle handling of the finished parts. Even parts such as piston bars can be unloaded without a scratch. The unloading tube is made of POM material. This also ensures gentle handling. Loading can be done via the main spindle and unloading via the sub spindle. It is also possible to load via the sub spindle and unload via the main spindle. Compatible with almost all types of lathes.

The SGS (Spindle Growth System) 4701 displacement measuring system is developed for high speed milling machine applications. Due to high machining speeds and the heat generated, the linear thermal expansion of the precision machine tool spindle needs to be compensated for in order to keep the tool in a defined position at all times. The SGS sensor measures the expansion of the spindle caused by thermal and centrifugal force. The measurement takes places typically on the labyrinth-ring. As well as the linear expansion, the temperature of the sensor is detected and output.These measurement values are fed into the CNC machine tool as correction values, compensating for any positioning errors.

UP milled parts are components that due to their geometric shape can only be produced with 4- or 5-axis machines with high-frequency spindle. The MM machines, developed by LT Ultra, make it possible to produce the parts economically and quickly.

The basis of short bar loader Multi 3000SL was developed in Switzerland. It was specially designed for turning machine types with a large distance between machine cover and spindle end. The bar feeder is supplied as standard with a Z-axis sliding unit to ensure free access to the Spindle Liner. This makes it easy to change the spindle insert tube. The Bar Loading Magazine is manufactured in Germany with first-class materials and components. The MULTI-3000SL guarantees long-term reliability. It impresses with its service and environmentally friendly design. It is also a fully electric and servo-controlled magazine. Due to the easy access to all parts it is extremely user-friendly. It is very simple to understand and therefore easy to operate. Due to the well thought-out design, set-up and changeover is possible within 2-5 minutes. The patented lifting mechanism guarantees an impact-free and fast loading cycle.

The automatic feeding of tools from the tool magazine to the machining spindle is implemented in modern machining centers with the aid of a tool changer. At the same time, this device is used to return tools to the tool magazine. Reducing non-productive times is an important criterion for increasing the efficiency of machining centers. The chip-to-chip time is directly positively influenced by a fast tool change, i.e. a short tool change time.
