About Walter
Walter Maschinenbau GmbH traces its roots to 1919, when Richard Walter founded the company in Düsseldorf under the name Walter Montanwerke. Headquarters moved to Tübingen, Germany, in 1924, and the company spent its early decades building a reputation in precision cutting tool manufacture. A pivotal milestone came when Walter launched the world's first NC-controlled tool grinding machine, and the Helitronic Power later set a new benchmark in the field. In 2004 the machine tool division was acquired by the Körber Schleifring Group, today known as the United Grinding Group, and the business was renamed Walter Maschinenbau GmbH.
The flagship product line is the Helitronic series of universal 5-axis CNC tool and cutter grinders, designed for both production grinding and resharpening of rotationally symmetrical tools. The Helitronic Power and Helitronic Power-F are the workhorses of the range, featuring a belt-driven spindle with two spindle ends that can carry up to six grinding wheels, a heavy grey cast iron gantry design for rigidity, and ball-screw linear axes with rapid traverse speeds of 15 m/min. The Power-F variant adds a second spindle end configuration suited to flexible multi-wheel setups. Higher-end models such as the Helitronic Vision use linear and torque motors in all axes for maximum dynamics, while the Helitronic Power 400 scales the platform for high-volume production of tools up to 315 mm in diameter. The product range is complemented by the Helicheck series of non-contact CNC optical measuring machines.
Walter CNC tool grinders serve manufacturers across aerospace, automotive, medical device, precision engineering, and woodworking industries. End users include cutting tool producers grinding carbide end mills, drills, step tools, reamers, and profile blades, as well as specialist shops producing surgical instruments, dental implants, and turbine component tooling. The machines handle HSS, solid carbide, PCD, and CBN tool materials, making them relevant wherever tight-tolerance rotary tools are produced or reconditioned.
Buyers seek used Walter Helitronic machines because the heavy cast iron construction and precision spindle systems retain their accuracy over many years of service. The widespread global installed base means spare parts, Fanuc and Bosch Rexroth control components, and Walter Tool Studio software support remain readily available. Strong resale values reflect the machines' reputation for micron-level repeatability and long service life, allowing shops to acquire proven CNC tool grinding capability at a fraction of new-machine cost.

Frequently Asked Questions
What is Walter best known for in CNC machining?
Walter is best known for its Helitronic series of 5-axis CNC tool and cutter grinders, which are used worldwide to produce and resharpen complex rotary cutting tools such as end mills, drills, reamers, and profile tools. The company, headquartered in Tübingen, Germany, has been a leader in CNC tool grinding technology since launching the world's first NC-controlled tool grinding machine.
What is the difference between the Walter Helitronic Power and the Helitronic Power-F?
Both machines are 5-axis universal CNC tool grinders built around Walter's rigid cast iron gantry design with a belt-driven spindle capable of carrying multiple grinding wheels. The Helitronic Power-F features a two-ended belt spindle configuration that allows each spindle end to be loaded with its own set of grinding wheels, providing greater flexibility for multi-wheel operations without manual changeover.
Why do shops buy used Walter Helitronic CNC tool grinders?
Used Walter Helitronic grinders are sought after because their heavy cast iron construction and precision spindle systems maintain micron-level accuracy long after initial installation. The large global installed base ensures that Fanuc and Bosch Rexroth control parts, spindle components, and Walter Tool Studio software remain widely available, supporting long-term serviceability and strong resale values.
