1 CNC grinding machine for micro tools CNC precision for tool diameter 0.5 to 12.7 mm Whether for medical technology, electronics, automotive engineering or aerospace, there s no end in sight for innovations in micro technology. In these markets small tools are necessary for precision manufacturing of the smallest of parts such as injection moulds, toothed gears, spindles, contacts and much, much more. This is why WALTER has designed the which offers the best premise for precise grinding results for tools from diameter 0.5 up to 12.7 mm. Grinding in Motion

2 for micro tools Production and/or regrinding with integrated robot loader (FANUC Robot) Enrich your range of services with the With the, WALTER extends your product range for the production and regrinding of the smallest diameter tools. The achieves precise grinding results for the production of tools from diameter 0.5 up to 12.7 mm and for re-grinding of tools from diameter 2.5 up to 12.7 mm. As an automatic 6-axis CNC machine, the is ideally equipped to carry out the complete processing of complex geometries for micro tools in a single clamping operation. All six axes are equipped with linear or torque drives and high-resolution direct measuring systems: a customised dynamic concept for precision micro grinding. With an A axis workhead speed of 1,000 rpm, the can accomplish precise cylindrical grinding operations, particularly for multi-step tools.

3 Innovative WALTER grinding technology WALTER portal design The with mineral cast machine bed has been especially designed for this application range. The CNC machine offers you optimum vibration damping, insensitivity to temperature fluctuations, drive dynamics and, ultimately, grinding precision. Tool shank steady rest Long, small diameter workpieces are guided on a hydraulically operated tool shank steady rest with fine adjustment enabling concentric running off the workpiece of 1 µ during the grinding process. Integrated robot loader (FANUC Robot) The grinding cycles for micro tools are normally short, making the time required for tool changing a very important consideration. The utilises a 6-axis robot loader integrated in the machine thus reducing the loading time to a minimum. Capacity up to 1,500 tools. Adaptive Control As the removal rate increases, the feed is automatically reduced, and vice versa. Depending on the tool type, you can save up to 30% of time used. Grinding wheels also last longer, as they are used consistently. Fanuc control system uses the 310i, Fanuc s newest control system, giving the best possible reliability and availability. Automatic positioning and measuring system Heli-Probe Collects important tool parameters and positions the tool as quickly as possible. Prerequisite for productivity. 2 3

4 Standard equipment for the highest performance in precision and flexibility X C X CNC controlled X axis With the X axis, the tools are automatically pre-positioned for grinding over the centre of rotation of the C axis. This means that only short axis traverse paths are required and high precision is achieved. 3 grinding spindle heads With 3 grinding spindle heads for up to 12 grinding wheels, the is designed for flexibility in application. This is of paramount importance for micro tools and tools with complex geometries.

WALTER grinding software The easy way to create a tool The latest version of the grinding software Helitronic Tool

This is a requirement for efficient grinding processes without restriction for tool design.

Thanks to the 3D-simulation the grinding result can be checked und optimized at the design stage if necessary.

5 WALTER grinding software The easy way to create a tool The latest version of the grinding software Helitronic Tool Studio from WALTER is even more powerful and simplifies the grinding of complex tool geometries. This is a requirement for efficient grinding processes without restriction for tool design. Helitronic Tool Studio This WALTER software works according to the WYSIWYG principle and represents a whole new level of programming simplicity. Machining and movement sequences for both highly complex, rotationally symmetric special and standard tools can be developed with minimal time outlay. The tool that you see on screen matches in every detail the tool your machine is producing. Thanks to the 3D-simulation the grinding result can be checked und optimized at the design stage if necessary. The Wizard technology uses the parameters you define to guide you quickly and reliably to the tool you require. Helitronic Tool Studio automatically adds all the remaining parameters. Further key information of Helitronic Tool Studio is the path optimised calculation of all axis movements as well as the collision check prior to production. This feature helps to support the zero-effect-philosophy. 4 5
