The adoption of the main axis movement method achieves high precision and high efficiency.
The cutting axis (X-axis) and the table axis (Z-axis) have been designed as independent structures. This eliminates any displacement of the X-axis due to the vertical movement of the Z-axis, achieving high-precision machining with a straightness of 1μm/300mm. It comes standard with an ATC (Automatic Tool Change) for 6 tools. The tool switching via the ATC device allows for processing of inner diameters, outer diameters, and end faces with a single chuck. The TVG-35C-2S, TVG-60C-2S, and TVG-90C-2S are equipped with a continuously variable indexing turret as standard, enabling highly efficient various complex machining. 【Specifications】 [TVG-60C] ○ Installation dimensions (width × depth × height) 2,700 × 2,500 × 3,770 mm ○ Maximum outer diameter of workpiece that can be chucked 600 mm ○ Maximum inner diameter of workpiece that can be ground 600 mm ○ Maximum weight of workpiece that can be chucked 1,000 kg ○ Spindle rotation speed up to 300 min-1 *For more details, please contact us or download the catalog.

Company information
The history of Toyo Eitech Corporation dates back to 1929. It began manufacturing grinding machines as a division of Toyo Kogyo Co., Ltd. (now Mazda Motor Corporation), which would later become an automobile manufacturer. The manufacturing technology for machine tools developed within the automobile industry has since received high acclaim in various leading industrial sectors. In particular, the internal grinding machines have been highly regarded, and today, the company is widely known as "Toyo of Internal Grinding," having grown into a manufacturer with a top-class market share in Japan.
