Higher efficiency in shaft grinding

Grinder Setup Time-Saver Package

Packaged functions useful for shaft grinding!
For highly accurate dimensional control of all outside diameters and dramatic reduction of setup change times.

More efficient shaft applications with Okuma's uniquely packaged grinding solutions

Achieving dimensional control of multi-step outside diameters

By NC positioning the wide range sizer, the measuring positions and diameters can be automatically changed by the program.
Providing setup time savings and highly accurate machining of multi-step OD parts.

By NC positioning the wide range sizer, the measuring positions and diameters can be automatically changed by the program.

Achieving all OD grinding in one chucking

A chucking jig is not required because the center hole friction drive is dual-center driven from the headstock and tailstock.
Since driver setup changes aren't required, and all ODs can be ground without a part flip, setup time savings and process-intensive grinding are possible.

Drive fixture becomes unnecessary with center hole friction drive with dual drive of headstock and tailstock

Workpieces of different lengths can be supported with no setup change

Workpiece support length and thrust can be automatically changed with the programmable NC tailstock.
Movement of the tailstock itself and thrust adjustment due to differences in workpiece length are no longer needed, and reduced setup time can be achieved.

Workpiece support length and thrust can be automatically changed with the programmable NC tailstock.
