What Is an Internal Thread Grinding Machine?

๋‚ด๊ฒฝ ๋‚˜์‚ฌ ์—ฐ์‚ญ๊ธฐ๋ž€?

An internal thread grinding machine is a specialized machine designed to precisely grind internal threads inside components. Compared to external thread grinding, internal thread grinding is far more demanding in terms of machining conditions and precision, requiring advanced technology and highly stable equipment.

Internal thread grinding Machines are mainly used for grinding fastener components in the aerospace and defense sectors, reducer components used in humanoid robots, and ball screws, which are experiencing growing demand in the automotive industry.

The demand for internal thread grinding machines is steadily increasing in the robotics industry. This is because high-precision thread machining is essential for assembling key components such as the robotโ€™s body, joints, arms, and legs. Given the frequent vibrations and high-speed movements involved, precise fastening and high durability are critical. In addition, internal thread grinding machines are widely used for machining ball screws for precise motion control, as well as fixing components inside reducers.
