CBD No. /2, 3 GM_DL DIA RB
Endmill HSS No. /2, 3, 4 GM_E2~4 CBN RB
CBD No. /2, 3, 4 GM_E2~4 DIA RB
Tap HSS No. /2, 3, 4 GM_DL CBN RB
CBD No. /2, 3, 4 GM_DL DIA RB
Reamer HSS No. /4, 6, 8 GM_DL CBN RB
CBD No. /4, 6, 8 GM_DL DIA RB

Outstanding operability

The GriStar Multi features easy operation with the easily viewable graphical display.

The machine employs collet chuck for clamping the tool, which makes tool grinding simple.

In addition, the machine has an offset compensation function that automatically measures the tool and compensate for the error to a minimum.

Faithful reproduction of the cutting edge

With GriStar Multi Evolution, you can set the tool data by yourself, such as the drill 1st relief, 2nd relief angle or the tip shape and so on.

Not only can they be made into the exact same shape as the new one, but they can also be made into an original shape suitable for the work.

Instant starting without programming

The GriStar Multi Evolution is capable of storing 5000 items of data for each tool. And the stored tool data can be easily retrieved.

It is also possible to manage the data by dividing it into folders according to its use, so the efficiency of data retrieving can be dramatically improved.

In addition, the tool installation is using the one chuck method, so it can be completed easily and in a short time without using other special tools.

Use contact type block stylus for high-precision

The measurement accuracy supports the high-precision of grinding. The GriStar Multi Evolution uses the block stylus in touch probe for high accuracy and high-speed measurement.

Faster and more accurate measurement of the cutting edge is now possible.




Improve functionality by software upgrades

Upgrading software, such as improving cutting methods and adding new functions, can be accomplished simply by importing digital data from a USB instead of replacing the control board.

You will be able to take advantage of the latest features even after the equipment is installed.
