Outstanding operability
The GriStar SP is a user-friendly machine by its easy-to-view screen operation and ease of tool installation.
Also, the fully automatic grinding system ensures stable accuracy.

Instant starting without programming
The GriStar SP is capable of storing data from over 10,000 items of tools. And the stored tool data can be easily retrieved with a screen touch.
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.
5-axis simultaneously control
5-axis grinding simultaneously control enable accurate positioning of works, and makes it possible to perform special types of grinding that were only possible with skilled workers.
The 5-axis control allows grinding to be completed with a minimum movement line, also reduces the grinding time.
Use contact type block stylus for high-precision
The measurement accuracy supports the high-precision of grinding. The GriStar SP 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.
Higher work efficiency
The efficiency of the work time from mechanical design to completion of the work is of great benefit to the companies. With GriStar SP, you can easily retrieve the stored tool data and install a tool with one touch, which dramatically reduces the time from set-up to preparation.
When grinding a large variety of products or small lots, productive and a significant machining time difference can be made depending on work efficiency. It’s exactly a profitable tool grinding machine.
Even in narrow places
The GriStar SP has about 1/3 of the occupied area of a competitor’s grinder, remarkedly reducing the interference with other machines and problems with movement lines.
When replacing an existing machine, such as a grinder, the extra space allows for an efficient flow line.
