Chucking Is Not Necessary!?
Just Put It on the Carrier and It's Ultra-Precision!!
Machining is always performed under the best conditions and high flatness accuracy can be obtained.
Machining of the two surfaces which is the standard of hexahedron machining.

It achieves ultra-precise grinding of two surfaces, which is the standard for machining hexahedrons, in a short time.It is also ideal for machining the end surfaces of parts that require flatness accuracy in the mounting area, such as bearings, piston rings, and gears.
Setting is completed just by placing the workpiece in the carrier set on the bottom grinding wheel. There is no need to think about holding the workpiece or setting up the jig. Workpiece size can be up to a maximum area of ⌀170mm.
Non-contact oil hydrostatic bearings are used on both the top and bottom of the grinding wheel spindle. In addition, the machine body has a unique frame structure, which means that deformation caused by uneven loads is extremely small.
A constant-pressure and constant-amount complex control system is adopted to the top grinding wheel spindle. Pressure applied to the grinding wheel is always detected to control the amount of cutting and pressure. Machining in the best condition is constantly achieved.
The pressure applied to the grinding wheel is detected in real time, and the cutting pressure and cutting amount are controlled by NC.
By linking with an articulated robot (OP) that can supply and remove workpieces, unmanned operation is possible. It can also automatically supply and remove bearing spacer workpieces and ceramic workpieces.
By linking with an articulated robot, workpieces can be automatically supplied and removed.
