Applying the technology cultivated in mass production of precision parts to general-purpose internal grinding machines! Introducing our processing examples.
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 (coaxiality) 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 equipped our CNC internal grinding machine STG-6N, which we manufacture and sell, with a newly developed 2-roll 1-shoe spindle, enabling high-precision machining of thin-walled workpieces. 【Case Overview】 ■Challenges - Susceptible to deformation due to gripping ■Results - Uniform wall thickness relative to the reference workpiece's outer diameter - Dramatic improvement in coaxiality of the inner diameter relative to the outer diameter after machining - Reduced deformation of the workpiece due to gripping, leading to expected improvements in roundness *For more details, please refer to the PDF document or feel free to contact us.
