Ultra-precise vertical rotary grinderSGR-700SP

Specular finishing leveraging sub-micron ultra-precision!

SGR-700SP

Drastic energy saving effect

IE3 standard motor compliant with "Energy Saving Law"
A drastic power consumption reduction can be achieved compared to legacy products when combined with the power saving effect of the permanent electromagnetic chuck

Auto-adjusting mechanism of Grindstone grinding pressure [Patented]

Chips and damage to the grinded surface can be reduced since only the necessary grinding pressure is applied. Precision machining can be applied not only to common materials but also to hard-to-grind materials.

Proprietary three-point supporting fixed table slope regulation mechanism [Patented]

Our proprietary mechanism is used for three-point support and the contact fixing method with the table. The table slope can be precisely and reliably adjusted by a sub-micron level.

Standard equipped with a permanent electromagnetic chuck table

The permanent electromagnetic chuck requires power only when absorbing and detaching the work material and becomes "permanent magnet" after absorbing the work material. Sub-micron level ultra-precise machining can be performed since there is no heat impact on the table of the work piece.

An elevating splash-guard cover is employed [Patent pending]

The splash-guard cover (front cover) can be opened automatically to the vertical direction. It provides not only good design but also facilitates working space when opened to 240 degrees in the front of the machine. It also allows better positioning and the operator can change set-up easily.
In addition, as it opens to the front, it is easy to install other devices such as an auto supply and discharge device. Also, can be utilized for diversified purposes such as integration to the automated line.

Automatic grinding size control system (optional) [Patent pending]

The newly developed automatic grinding size control system is different from the legacy size controller in that it allows automatic grinding by specifying the dimension (in value) of the work finishing. As the system measures the dimension (thickness) of the work material and the remainder of the grindstone at the same time, work errors can be avoided and the time required for set-up change can be significantly reduced. Thus allowing a wide-range of users from beginners to experienced.

Ultra-precise grindstone feed mechanism

TYPE II is equipped with an ultra-precision mechanism that realizes the cut depth of 0.1 μ/min, one tenth of the cut depth that the standard machine can provide. Its fix abrasive grains allow ultra-precise machining and the system is suitable for not only metal but also works with rigid surface including new materials and glass.
The system has gained a good reputation by the engineering departments of universities and different research laboratories.
