The GF32Mi-63 by JTEKT Toyoda is a high-precision, single-wheel CBN Crankshaft Grinding Machine designed for the accurate and highly productive grinding of medium-length automotive and industrial engine crankshafts.

The GF32Mi series represents the latest generation of crankshaft pin grinders, offering a potent combination of high speed and high accuracy. This model features an extended capacity with a Distance Between Centers of 24.8 inches (630 millimeters).

The machine’s superior performance is driven by a single linear motor wheelhead that operates on a static pressure slideway. This high-response wheelhead feed mechanism minimizes motion loss and backlash, contributing to an exceptionally accurate and high-quality grinding surface. Its sturdy construction, including a 3-point support bed, is designed to provide high rigidity, reduce thermal displacement, and maintain long-term steady machining precision.

Core accuracy is guaranteed by JTEKT’s foundational technologies: the patented TOYODA STAT BEARING and a floating plate, which ensure stable operation and eliminate bearing wear. The machine is controlled by the reliable Toyoda GC50 controls, which simplify operations like wheel replacement and support flexible machining with a rich selection of grinding methods. The GF32Mi-63 is an excellent choice for manufacturers requiring high-volume, high-precision finishing of crankshaft main journals and pins.
