What is internal grinding?

What is internal grinding?

High-precision grinding is possible! It is mainly used for automotive parts such as gears and bearings!

"Internal grinding" refers to a machining technique for grinding the inner surface of cylindrical objects, also known as inner surface grinding or internal grinding. The object itself is rotated while the grinding wheel is also rotated and inserted into the hole for grinding. This allows for simultaneous grinding of both the hole and the end face, enabling high-precision grinding. It is mainly used for automotive parts such as gears and bearings. 【Features】 ■ Machining technique for grinding the inner surface of cylindrical objects ■ The object itself is rotated while the grinding wheel is rotated and inserted into the hole for grinding ■ Simultaneous grinding of both the hole and the end face is possible ■ High-precision grinding is achievable ■ Used for automotive parts such as gears and bearings *For more details, please refer to the PDF document or feel free to contact us.
