The GF16S-25 by JTEKT Toyoda is a high-precision, compact CNC Crankshaft Grinding Machine designed for the high-speed and accurate grinding of small-sized crankshafts.

The GF16S series provides exceptional grinding accuracy in a space-saving compact design, making it a powerful solution for precision manufacturing of small crankshafts. It is a CBN crankshaft grinder that achieves high levels of precision and speed through its advanced engineering.

A core feature is the adoption of a Direct Drive (DD) wheel spindle. This system reduces the weight and lowers the center of gravity of the wheelhead compared to traditional belt-drive systems, which significantly improves the wheelhead’s ability to follow complex movements for high-accuracy grinding. This patented performance is further bolstered by the TOYODA STAT BEARING and a floating plate system, ensuring long-term, stable accuracy by eliminating bearing wear.

The machine is capable of process integration, allowing for both outer diameter grinding and shoulder grinding to be combined into a single, efficient process. This consolidation improves cycle time and overall productivity. Operators control the machine with the advanced Toyoda GC70 controls.
