Features

Changing the Concept of Rotary Grinding.
Unparalleled Ultra-Precise and Ultra-Efficient Rotary Grinder.

1.Hydrostatic Rotary Table for Accurate and Efficient Surface Machining

The rotary table guideway employs a unique non-contact NAGASE original hydrostatic mechanism to restrict table top surface deflection to the submicron during table rotation. In addition, the height of the table travel line does not change even when the table rotation speed changes so that high flatness is achieved.

2.Suitable for Simultaneous of Many Pieces and Grinding Large Workpieces and Ceramics.

Chuck sizes from ⌀500 to ⌀800 mm are available for simultaneous grinding of a large number of small parts and machining of medium-sized parts. Ideal for machining ceramic materials such as electrostatic chucks.

3.Higher Grade Machining Quality by Grinding Wheel Spindle Incorporating an Ultra-Low Vibration Motor

The NAGASE original ultra-low vibration motor (rotational vibration below 0.05μm) is employed in the grinding wheel spindle as a drive motor. Combined with the ultra-rigid body structure, it can be used for both ultra-efficient machining and ultra-precise mirror machining.


4.Shape Machining and On-Machine Measurement Can Be Performed at Will.

In addition to flat surfaces, can also freely perform shape machining that involves synchronizing table feeding and the vertical axis.
On-machine measurement by touch probe (OP) is also available.

5.Dresser to Ease Cutting of Hard-to-Cut Materials

In addition to single-point dresser, double cup-truer (OP) and orthogonal rotary dresser (OP) can be mounted. Supports grinding of hard-to-cut materials such as carbide and ceramics, as well as mirror surface grinding.

6.Finishing of Workpiece ID and OD Is Possible

Vertical head (OP) enables internal/external grinding.
The byte holder (OP) enables cutting.
