ONE 5‐Axis Flexible Tool & Cutter Grinding Machine With Numroto Tool Design Software

Strausak, a leading machine tool manufacturer based in Biel, Switzerland, extends its global position in the field of multi‐axis CNC grinding by launching the brand‐new model ONE 5‐axis flexible tool & cutter grinding machine with Numroto tool design software for the grinding of rotary and stationary cuƫtng tools in small and large batch production, for custom cuƫting tools as well as for resharpening. 


This model has been designed so that any options can be upgraded and retrofitted at any time during the life of the machine. 

Thermal stability and Cpk process capability index: 

The thermal stability is exceptionally high due to an innovative machine design and a rigid 5‐axis configuration. Field tests have demonstrated an unusually high Cpk process capability. This is of particular importance when grinding short‐run custom tooling where accuracy and “first‐tool‐good” are critical. 

Linear motors: 

Linear motion technology is included in this machine which ensures outstanding surface finishes both on radius and other primary reliefs as well as flute finish. Linear motors also reduce the footprint of the machine. 

Synchronous grinding spindle: 

The highly efficient synchronous spindle, running at max. 40% power draw or less, does not release any heat into the machine or into the grinding process. This greatly helps with a consistent grinding process and keeping the thermal stability. 

Numroto software: 

This software platform offers the user high‐performance tool design and intuitive programming for an unlimited range of applications. 


This machine presents the smallest possible footprint among any tool grinder with a 32 mm (1.1/4”) capacity, without any compromise in rigidity, sturdiness and power for production grinding. 

Strausak produces scalable and modular grinding equipment: 

Any option can be retrofitted on site after delivery to help the owner to stay competitive in a dynamic and unpredictable environment. These are some of these scalable options: 

  • Upgrade to 32 hp synchronous grinding spindle 
  • Upgrade to 8‐position or 12‐position wheel changer 
  • Upgrade to 8‐position collet sleeve changer 
  • Pick‐and‐place loader with Rollomatic cassette systems 
  • High‐speed Staubli robot with Rollomatic cassette systems 
  • Automatic cassette magazine to extend the autonomous production grinding 
  • Wide range of collets and adjustable clamping systems 
  • V‐block shank guidance 
  • Retractable tool support, traveling steady rest, Arobotec steady rest 
  • Manual and automatic tailstock 
  • High‐speed spindle with 3‐position automatic grinding pin changer 
  • Onboard wheel dressing 
  • Automatic wheel sticking 

Included in the machine are some of the following opƟons: 

  • 4‐position automatic wheel changer 
  • Tool probing 
  • Wheel probing 
  • Quick‐change collet system 
  • Ergonomic design of control panel with verƟcal height adjustment

Related Glossary Terms

  • collet


    Flexible-sided device that secures a tool or workpiece. Similar in function to a chuck, but can accommodate only a narrow size range. Typically provides greater gripping force and precision than a chuck. See chuck.

  • computer numerical control ( CNC)

    computer numerical control ( CNC)

    Microprocessor-based controller dedicated to a machine tool that permits the creation or modification of parts. Programmed numerical control activates the machine’s servos and spindle drives and controls the various machining operations. See DNC, direct numerical control; NC, numerical control.

  • dressing


    Removal of undesirable materials from “loaded” grinding wheels using a single- or multi-point diamond or other tool. The process also exposes unused, sharp abrasive points. See loading; truing.

  • grinding


    Machining operation in which material is removed from the workpiece by a powered abrasive wheel, stone, belt, paste, sheet, compound, slurry, etc. Takes various forms: surface grinding (creates flat and/or squared surfaces); cylindrical grinding (for external cylindrical and tapered shapes, fillets, undercuts, etc.); centerless grinding; chamfering; thread and form grinding; tool and cutter grinding; offhand grinding; lapping and polishing (grinding with extremely fine grits to create ultrasmooth surfaces); honing; and disc grinding.

  • grinding machine

    grinding machine

    Powers a grinding wheel or other abrasive tool for the purpose of removing metal and finishing workpieces to close tolerances. Provides smooth, square, parallel and accurate workpiece surfaces. When ultrasmooth surfaces and finishes on the order of microns are required, lapping and honing machines (precision grinders that run abrasives with extremely fine, uniform grits) are used. In its “finishing” role, the grinder is perhaps the most widely used machine tool. Various styles are available: bench and pedestal grinders for sharpening lathe bits and drills; surface grinders for producing square, parallel, smooth and accurate parts; cylindrical and centerless grinders; center-hole grinders; form grinders; facemill and endmill grinders; gear-cutting grinders; jig grinders; abrasive belt (backstand, swing-frame, belt-roll) grinders; tool and cutter grinders for sharpening and resharpening cutting tools; carbide grinders; hand-held die grinders; and abrasive cutoff saws.

  • shank


    Main body of a tool; the portion of a drill or similar end-held tool that fits into a collet, chuck or similar mounting device.

  • steady rest

    steady rest

    Supports long, thin or flexible work being turned on a lathe. Mounts on the bed’s ways and, unlike a follower rest, remains at the point where mounted. See follower rest.
