The precision grinding performer, TGR-250, polished at the peak of technology.
The TGR-250 is a state-of-the-art tool grinding machine that achieves a high level of precision. Previous tool grinding machines had various challenges. In particular, the drive for the A-axis and C-axis, which are the rotating axes, used gears, making it impossible to avoid a decrease in grinding precision due to backlash. As the years of use increased, regular maintenance was required, including periodic adjustments for backlash to address deterioration, and replacement was necessary when wear progressed. The TGR-250 has newly adopted direct drive motors for the A-axis and C-axis, achieving an astonishing backlash of "0". This has dramatically improved the potential of the tool grinding machine.

basic information
【Features】 ○ Standard Equipped with Rotary Encoder The rotating axis is equipped with a rotary encoder as standard, achieving high indexing accuracy at speeds below 0.001 degrees. Additionally, by eliminating vibrations from gear impacts, we have succeeded in obtaining precise and smooth movements. The roughness of the processed surface has also improved, realizing an unprecedented level of grinding precision. ○ Grinding Wheel Spindle Adopts a built-in type with 18.5KW. It not only ensures stable grinding but also allows for high-precision finishing surfaces. Furthermore, the use of a cam-type grinding wheel changer has significantly improved responsiveness. ○ Confirmation with 3D Simulation Before grinding, you can confirm the completed image in 3D visuals. No complicated operations are required. It can be used by anyone with a simple one-click operation. ● For other functions and details, please download the catalog or contact us.
