Taking highly accurate and user-friendly grinding to a new level

Large CNC general purpose cylindrical grinders


Unique “floating plate” ballnut ensures repeatability
In order to provide highly accurate grinding over a long period of time, we adopt a JTEKT original type of wheelhead feed mechanism.
Accuracy of roundness and cylindricity are improved as the runout of the ball screw are absorbed.

Radius crowning traverse grinding cycle
For rolls, etc where crowning is required, a skilled operator with grinding know-how must constantly attend the machine, in some cases sacrificing productivity.

To avoid this, the GE6i features a Radius crowning traverse grinding cycle that makes it possible for Operators of all skill levels to grind a crowning shape by simple input, using the 2-axis CNC function.
