Walter Helitronic rotary eroding and grinding machine

Creating Tool Performance, a member of the UNITED GRINDING Group HELITRONIC VISION DIAMOND 400 L Two-in-one, high-performance rotary eroding and grinding machine WALTER KÖRBER SOLUTIONS Grinding Eroding Laser Measuring software Customer Care Walter Maschinenbau GmbH WALTER has produced tool grinding machines since 1953. With the introduction to the market of the HELITRONIC series for the complete machining of rotationally symmetrical tools, WALTER became the leader of the world market. Today, our product range is supplemented by fully automated CNC measuring machines in the HELICHECK series for contact- less complete measurement of tools and production parts. Walter Maschinenbau GmbH is part of the UNITED GRINDING Group within Körber AG, which has significant financial strength and well-tested processes. Together with our sister company, Ewag AG, we consider ourselves to be a supplier of systems and solutions for the complete machining of tools and can offer a wide range of products, including grinding, rotary eroding, laser machining, measurement, and software. Our customer focus and our global sales and service network of company- owned locations and employees have been appreciated by our customers for decades. WALTER HELITRONIC VISION DIAMOND 400 L The HELITRONIC VISION 400 L at a glance Application: The machine Eroding and grinding of rotationally symmetrical tools Optimized low-vibration solid mineral cast, gantry-type construction for metalworking and woodworking industries Linear X, Y, Z axes with linear drives For production and/or regrinding Rotating A, C axes with high torque motors Fully automated, complete machining in a single clamping cycle Twin-driven spindle with two ends or belt-driven spindle with one end Materials include PCD, CBN, HSS, carbide, cermet, ceramic or motor spindle with one end Up to three rotation electrodes on one spindle end and up to three grinding wheels on the other spindle end or a total of six grinding wheels Three-stage eroding process for the highest quality finish FANUC, the global standard for control equipment Various loading systems Numerous efficiency options HELITRONIC VISION DIAMOND 400 L with Top loader and Electrode/grinding wheel changer, right uncompromising in productivity and precision Optionally available also as a version with ball screw drive HELITRONIC VISION DIAMOND 400 WALTER HELITRONIC VISION DIAMOND 400 L Software HELITRONIC TOOL STUDIO, CAD/CAM software for design, programming, simulation, and production HELITRONIC TOOL STUDIO with license erosion Walter Window Mode WWM optional Numerous software options to extend the system's performance and to increase its efficiency HELITRONIC VISION DIAMOND 400 L with the Robot loader 25 left and Electrode/grinding wheel changer, right options, the ultimate configuration for high performance WALTER With the three-stage eroding procedure, the HELITRONIC VISION DIAMOND 400 L sets new benchmarks for quality for PCD tools. It is an economic investment for both the production and resharpening of PCD/CBN tools in the diameter range of up to 315 mm. It is possible to save time by machining complex geometries in a single clamping cycle. The combination of eroding and grinding provides a real step forward in terms of flexibility and quality. Furthermore, thanks to its two-in-one principle, the HELITRONIC VISION DIAMOND 400 L can be used as a grinding machine for the production and resharpening of carbide tools. The changeover from PCD to carbide tools is on the fly, since it is possible to automatically change between PCD and carbide tools and back again. WALTER HELITRONIC Innovative WALTER eroding and grinding technology Motor spindle option The powerful single-ended directly driven motor spindle is equipped with a liquid cooling system. Up to three electrodes/grinding wheels can be mounted per adapter. In combination with the electrode/grinding wheel changer, up to 24 adapters (72 electrodes/grinding wheels) can be used in the grinding process. The result is the highest levels of efficiency and productivity. Optionally available upon request only also as a motor spindle with 24,000 rpm. Belt-driven spindle with two spindle ends standard Belt-driven interchangeable spindle option The double-ended, belt-driven spindle is driven by a powerful motor. Each end of the spindle can take up to three electrodes/grinding wheels. The interchangeable belt-driven spindle with one spindle end is eminently suitable for optimal utilization in combination with an electrode/grinding wheel changer system. This high-performance drive features the same capacity properties as the motor spindle. Powerful single-ended motor spindle with up to 33 kW peak power Belt-driven spindle with two ends and up to six electrodes/grinding wheels for automatic changing of electrode/grinding wheel sets (optional) Belt-driven interchangeable spindle Automated work table option Grinding wheel dresser option This option can be equipped with up to two upper slides: one with automatic traverse and one fixed. This way, long tools can be supported by a moveable steady rest and/or a tailstock. The surface quality and tool precision are enhanced as a result. Sharpening stone holder option With the permanently installed sharpening stone holder, WALTER enables the automatic opening of the wheel bond during production. The HELITRONIC TOOL STUDIO software controls the process and enables the operator to open the bond at the appropriate time according to the grinding wheel condition. Other options Automatic grinding wheel measurement Automatic, electrical measurement For even more efficient production. Normally, the machine operator corrects the grinding wheel data in the production process manually so that the geometry of the tool can be maintained at the nominal dimension. With the automatic grinding wheel measurement, the wear on the bond of the grinding wheels can be determined automatically via tactile measurement, exactly documented and compensated for. The measurement is carried out during the production process. Diameter and length of the grinding wheel can be measured and compensated for. This means that the operator always has the optimum grinding wheel data at the desired time. Furthermore, the user can monitor the grinding wheel wear and thus influence the production process and optimize it. The probe for the tactile measurement is fitted on the tool carrier and is mounted in place of the electrical dresser. Automatic positioning and measurement Integrated Measuring System 1MS system Helic-Probe standard With the integrated 1MS measurement system, Helic-Probe records important tool parameters such as the outside diameter, rake angle, and core diameter. A perfectly positioned tool in the shortest space of time. This is the best precondition for quick and accurate grinding, quality, and productivity. Calibration standard values, by thermal growth or wheel wear Calibration consists of a calibration ball and software. It is used to automatically calibrate the X, Y, and Z axes of the machine with a loaded arm. The calibration frequency can be freely chosen in the loader program. Machines without a loading system can be calibrated manually

New benchmarks for tool design in PCD tools with HELITRONIC TOOL STUDIO What you see is what you grind. This is the motto for grinding with the HELITRONIC TOOL STUDIO. If one would like to describe the advantages of License Erosion in a single sentence, then the best choice would be: What you can grind, you can also erode. Thanks to the wizard technology, the operator needs only a few mouse clicks for the production of a perfect PCD tool: Design, program- ming, simulation, and production. Milling cutter with PCD veins WALTER HELITRONIC VISION DIAMOND 400 L FINEPULSE TECHNOLOGY New standard, new benchmark FINE PULSE TECHNOLOGY Improvements can be seen with the naked eye The new FINE PULSE TECHNOLOGY eroding concept sets new standards in terms of the surface quality, cutting edge quality, and process reliability of PCD tools. The basis for this is the new liquid-cooled generator with an increased pulsation frequency. It is now installed as standard in all Two-in-one eroding and grinding machines from WALTER. The difference to the other tools on the market can even be seen with the naked eye on the most common PCD types with 10 μm grain size. A tool produced with FINE PULSE TECHNOLOGY on a WALTER eroding machine shines on its free surface, similar to a polished ground tool.
