We would like to introduce our processing case that has achieved high-precision machining of thin-walled workpieces. Workpieces that require internal grinding often demand not only roundness and surface roughness but also runout (concentricity) relative to the outer diameter. This is particularly challenging for thin-walled workpieces, where deformation due to gripping becomes an issue. To address this, we have developed a new 2-roll 1-shoe spindle, which has been installed in our CNC internal grinding machine STG-6N, enabling high-precision machining of thin-walled workpieces.
