The GE4i-100 INTER is a high-accuracy, production-focused Internal Diameter Grinding Machine from JTEKT Toyoda. It is engineered to deliver exceptional precision for grinding the internal bores of components in high-volume manufacturing environments.
GE4i-100 INTER
The GE4i-100 INTER is a dedicated High Accuracy Internal Cylindrical Grinding Machine that brings JTEKT Toyoda’s core precision technologies, typically reserved for external grinding, to the internal machining process.
The machine’s foundation is built for superior stability and positioning accuracy, incorporating the patented TOYODA STATº BEARING and floating plate ball nut technology. This ensures maximum rigidity for the grinding spindle, resulting in long-term dimensional accuracy and superior finish quality on internal surfaces.
The GE4i-100 INTER is configured for medium-sized precision parts, offering a Swing Over TableØ12.6″ (320 mm) and a Workpiece Length capacity of 39.4″ (1,000 mm). It is primarily specified for Machining I.D. up to Ø5.9″mm), making it an essential tool for manufacturers requiring precision internal features on sleeves, housings, and other critical components. It is also capable of handling a Maximum Grinding Diameter o11.8″ (300 mm), allowing for combined internal and external grinding operations.
The GE4i INTER features internal grinding specifications with the same patented Toyoda Stat Bearing and floating plate ball nut technology of external grinding to ensure high accuracy and positioning.
