The Star NXT Tool Grinder
Small Footprint Machine with a Large Grind Zone
The NXT generation of tool grinding has arrived. The NXT Tool Grinder is a small footprint machine, with a large grind zone. The machine has the ability to run small and large diameter wheels, has easily configurable options, combined with the efficiency and stability from previous Star tool grinders.
Learn more about the engineering process that went into developing the NXT in Star Cutter News.

The three available spindle options support all needs ranging from light duty manufacturing to heaving fluting and all-purpose manufacturing.
A large grind zone, that provides the ability to run small and large diameter wheels.
The NXT offers both standard and extended length tooling rails, which allows for the use of rail mounted steady rests and tailstocks at various tool lengths.
Robot gripper: capable of holding tools from 5 to 32mm in diameter. Optional gripper fingers available for gripping sizes below 5 mm and above 32 mm.
Optional 12,000 RPM wheel dresser: for manufacturers who intend to produce and maintain precision contours in grinding wheels
What the market has been asking for
With the introduction of the Star NXT CNC tool and cutter grinder, manufacturers now have what the market has been asking for: a small footprint machine, with a large grind zone, that provides the ability to run small and large diameter wheels. The NXT combines the best aspects of our previous machines, with a modular design that offers easily configurable options and a competitive price
point. With industry leading NUMROTO software on a machine manufactured and supported in the USA, the NXT is the smallest and most capable CNC tool and cutter grinder on the market.

The GDS μGrind Chuck
This automatic blank clamping system lets you virtually eliminate both radial and axial runout without special tools or skill. Interchangable collets from 3 to 20 mm allow you to change diameters in seconds and maintain a 2µm repeatability. The Star Applications team has tested this with our automation package, and found repeatability of the TIR and clamping length between blank loads to be less than 2µm as advertised . . . sometimes even less than 1µm!
