Click to edit any feature from one screen to create specials, saving time and aggravation. instant 3D simulation of what you’ll grind.

The right auto-loading solution for you, regrinding or production

Whether it’s an ECo-loader for 20-165 tools, a disk loader for 60-120 tools, or a production loader for hundreds of tools, we have the right automation solution for you. And all systems allow you to mix tool types and sizes.

Maximum rigidity and minimal axis travels

Walter’s patented 3D gantry design has proven to be the optimal solution for tool grinding. The grinding spindle rides on a massive cross slide secured by a closed backwall.. A large C-axis under the workhead makes the rotary motion needed to complete a tool in one setup, eliminat-ing the need for a rotary spindle axis and resulting in the most rigid concept possible

SmartProbe automates K-land and other setup challenges

The SmartProbe automatically measures features like fl ute depth, fl ute length, rake angle, radial angle of end teeth, and spiral lead to greatly reduce the setup time for regrinding and minimize operator error. it even digitizes multiple cutting edges for regrinding variable and multi-helix endmills.

Fanuc control & drives for rock-solid reliability

Fanuc controls and drives have the lowest failure rates in the world. Plus there are more service locations and part supplies are guar-anteed for 20 years. Plus most operators and maintenance personnel are very familiar with Fanuc. Strict separation of the CnC and the PC virtually eliminates the risk of viruses and sys-tem crashes. Precision in the nanometer range.

Some of the many reasons the Helitronic is by far the world’s most popular CnC tool grinder

Adaptive Control cuts cycle times up to 30%

The machine automatically adjusts the feed rate to maintain optimum load on the wheel without sacrifi cing quality, fi nish, or wheel life. The result is the shortest possible cycle times, maximum wheel life, and extended unmanned operation.

Internal Measuring System (IMS) main-tains endmill quality over a long production run without human intervention

Compares measured tool values with nominal values to calculate offsets for wheel wear. Maintains tool accuracies in the range of +/- 0.0003” on diameter and fl ute depth and +/- 1° on rake angle. Automatically re-calibrates by touching off several points on a chrome ball on the workhead, so it’s always accurate, regard-less of temperature fl uctuations.

Integrated wheel dressing and opening removes need for human intervention during long production run

Auto-loading tools does little good if you have to stick the wheel frequently or if the wheel breaks down. Walter machines can automati-cally maintain a free-cutting wheel, whether its diamond or CBn, with the dressing stick mounted to the workhead in the upper right. integrated dressing automatically maintains the form of vitrifi ed CBn wheels.

Wheel changer extends and optimizes automation

Grind longer unmanned. Automatically switch between different tool types. Mix carbide, HSS, and other tool materials. You can use up to 12 wheel sets on a Vision machine or 8 on a Power and the wheel change time is under 10 seconds.

Helitronic Tool Studio grinding software combines incredible flexibility with ease of use

Tool Studio makes it easy to design and manufacture complex or unique cutting tools. With Tool Studio, you model the tool with an interactive 3D graphic – changing any feature. When you like what you see, send it straight to the machine because the grinding program has already been written in the background! To maximize productivity, do all the setup on an office PC. Simply transfer the file to the grinder when you’re ready to make real tools.

See the complete machine, including workholding, and the grinding sequence. Check for—and eliminate—collisions. See the full 3D simulation on the machine control in real time.

The Tool Wizard shows only the relevant parameters and guides you quickly and reliably to a finished tool

“What You Model Is What You Grind” Every change appears instantly in a high- resolution 3D graphic and automatically rewrites the grinding program in the background. Watch your grind in real- time on the machine control – so clear and accurate it’s like you’ve turned the coolant off in the machine.

Unlimited flexibility Add any number of grinding operations per tool, mix and match operations, and change any individual feature to create geometries of any complexity. Everything – including simulation – is within one software package and most everything is changeable: Variable helix...Variable rake...Variable core...Variable land width...

Wizards offer easiest way to make standard tools For standard tool families, Wizards show only the relevant data, minimizing the data input required. The software then uses a database built on decades of WALTER tool grinding experience to complete the grinding program with astounding speed. At the same time, more proficient users can take a standard tool as the basis for more complex designs by adding new operations.

Tool Studio makes it easy to grind features like a “ski-fl ute” within the main fl ute, creating an aggressive rake at the cutting edge without compromising core strength Click to edit anything from one screen—

Saves time and aggravationSimply clicking the 3D graphic lets you see anything relevant to that part of the tool: grinding parameters, operations, wheel data, a 2D cross section, a profi le view, and a complete machine view. You can even snap the wheel to the current position or turn the operation on and off. You don’t have to hunt through separate windows and menus. You can optimize tool holding positions for maximum rigidity, simulate custom workholding, and detect and eliminate collisions.

Plus you can measure tool features from this central screen, try new design ideas, and check the results instantly—before grinding any real tools.

Auto-loader for up to 504 tools

The optional integrated loader automatically loads and unloads up to 504 tools, paving the way for multiple-shift operation with minimal manning. Plus you can prepare, program, and install up to two new pallets while the machine grinds tools from the “in process” pallet. This maximizes productive machine time for improved profitability. (The number of pallets you can use depends on tool length.) Choose from a “classic” gripper system with three smaller diameter ranges and a high capacity or a “one-range” system that handles tools from 1/8 to 1” in diameter without changing grippers. Tool change takes only seconds, because one gripper pair removes the finished tool and and a second pair loads a new blank into the workhead on the same trip into the machine. The grippers travel back and forth on a rigid cross slide, allowing for fast yet accurate handling. You can program the vertical pickup point for each tool in a pallet in any sequence to accommodate different tool lengths, flute lengths, tool types or chuck mounting positions. You can also program the loader either at the machine or on an office PC using an Excel spreadsheet.

The double gripper for fast exchanges between blank and finished parts in a position. The pallets are programmed in-process. You can load up to 3 cassettes with blanks or tools.

Helitronic Power – Flexible production and re-sharpening of metal- and woodworking tools

Integrated wheel dressing and opening removes need for human intervention during long production run

Auto-loading tools does little good if you have to stick the wheel frequently or if the wheel breaks down. Walter machines can automatically maintain a free-cutting wheel, whether its diamond or CBn, with the dressing stick mounted to the workhead in the upper right. integrated dressing automatically maintains the form of vitrified CBn wheels.

All WALTER loading systems accommodate tools of different sizes and types in any order you choose. Each can be used with different workholding options, depending on tolerances and the diameters you need to mix in a batch. You can also setup and program loaders while the machine grinds tools. And because the loaders are simple, rigid, fully integrated with the grinder, and CnC controlled, travels are short and tool changes are quick.
