FLX Tool Grinder

The Star FLX 5-axis tool and cutter grinding system has been designed with a focus on flexibility, accommodating a wide range of applications while enabling users to modify features to exactly match their grinding needs. Additionally, the FLX has automation and wheel change features that make it well-suited for high-volume, lights-out manufacturing.

Suited for a variety of applications, including:

End Mills
Drills
Boring Bars
Form Cutters

The Star FLX 5-axis CNC tool and cutter grinder allows manufacturers to run both small and large diameter tools, yet is packaged in a cost-effective and extremely compact footprint. Leveraging Star Cutter’s expertise in grinding machine design, the enhanced features of the FLX enable faster and more efficient manufacturing that fits today’s move toward unmanned production.

NUMROTO Software

FLX grinders feature the latest FlexiumPro CNC solution, which is 10 times faster than previous generations. This comprehensive software package offers the ability to manufacture or regrind a wide range of tools as efficiently as possible.

FlexiumPro retains and extends all behavioral and functional aspects of NUM’s Flexium+ system including a reduction in power consumption, a smaller electrical panel footprint and improved data security. As in previous versions, FlexiumPro provides control of up to 32 axes and/or spindles, 3D simulation, extensive and precise probe cycles for tool and wheel, in-process wheel dressing, job control, creation of elevation drawings, adaptive grinding and more.
