Steady Rest
For precision tool support. 25mm of travel allows for the rest to drop down and out of the way for automated loading and unloading.
The Star Cutter NXT CNC 5-axis tool and cutter grinding system provides a large grind zone that enables manufacturers to run both small and large diameter tools, yet is packaged in a cost-effective compact footprint. The NXT leverages the heritage of Star Cutter’s previous grinding machines’ capability reimagined in a modular design that offers easily configurable options at a competitive price point.

For precision tool support. 25mm of travel allows for the rest to drop down and out of the way for automated loading and unloading.
Optimize your production with the addition of an optional, FANUC 200iD interfaced with our NXT to handle all loading and unloading of blanks to finished tools.
Optimize space in the automation pallet bay as it holds two full pallets and two unload pallets. As an example, capacity on .375" tool blanks is 260 pieces.
Handle a variety of applications with the up to 5-station wheel changer. Loads wheel packs and coolant manifolds for quick changeover and maximum uptime.
Ideal for applications from tool regrinding through large tool production. Two sizes for optimized torque and power — 28kW at 20,000 RPM or 15kW at 24,000 RPM for smaller diameter wheels.
Auxiliary W-axis runs parallel to the Z-axis and is independently servo-controlled. Allows for programmable positioning of tool supports as well as a follow steady-rest option for fluting support.
Optional 12,000 RPM wheel dresser offers renewed cutting action for producing and maintaining precision contours on grinding wheels.
Standardized platform decreases lead times while enabling quick adaptation to specific customer application requirements
Multiple wheel change options
Handle tool regrinding to large production
Programmable positioning of tool supports
Standard and extended length tooling rails to accommodate various tool lengths
Eliminates backlash, friction effects and drive vibration as compared to ball screws
Compact design to save on floor space

NXT grinders feature the lastest Flexium + CNC solution with NUMROTO, a comprehensive software package for producing and resharpening a wide range of tools. Even the most complex shapes can be easily programmed and executed.
A complete NUMROTO solution includes many functions to manufacture or regrind a tool as efficiently as possible. With functions such as 3D simulation, extensive and precise probe cycles for tools and wheels, in-process wheel dressing, job control, creation of elevation drawings, adaptive grinding and more, the system can be expanded per user needs.

Based on current Windows systems, NUMROTO can be integrated into the company network. Central storage and administration of part programs and extended back-up functions are therefore easy to implement.


To serve the medical grinding community, Star Cutter and Hexagon Manufacturing Intelligence have an exclusive partnership where ESPRIT CAM software is pre-packaged to run the Star Cutter 5-axis software right out of the box. ESPRIT is a high-performance CAD CAM system for CNC programming, optimization and simulation. Well known for its machine-optimized, edit-free G-code (toolpath), ESPRIT leverages a digital twin simulation platform to model the finished part, tools, and CNC machine. AI-based algorithms eliminate manual data input and provide machine operators with greater assurance of what will happen on the shop floor. The result – simplified programming, increased tool life and utilization, reduced cycle times and improved productivity.
This packaged solution is perfect for manufacturers of complex medical tooling, such as hip rasps, rotary files, bone files and drills, etc. ensuring that your machine will launch quickly and keep running at top efficiency.
Star SU delivers world-class gear cutting tools, advanced coating technologies, and engineering expertise that help manufacturers improve precision, productivity, and performance. Driven by decades of innovation and global expertise, we engineer complete solutions that support the evolving demands of gear manufacturing worldwide.
