The TGR-016α has received great acclaim as an NC tool grinding machine specialized in "tool edge sharpening." To prevent chipping and chipping on the cutting edge of carbide drills, a "small chamfer" is applied to make the coating less likely to peel off. Our company has been working on development with the goal of processing "with high precision," "easily," and "more quickly" using NC tool grinding machines. By introducing the machine, we eliminate the "difficulty of passing down skills" through manual craftsmanship. Additionally, the program has evolved, making it easy to shape complex cutting edge geometries. 【Benefits of Introducing the Machine】 ■ Eliminates the "difficulty of passing down skills" through manual craftsmanship ■ Resolves "variability in processing quality" caused by manual work ■ The program has evolved, making it easy to shape complex cutting edge geometries *For more details, please refer to the PDF materials or feel free to contact us.

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.
