CNC Machine X Ball Screws
Ball screws are used in applications that require precise linear motion with minimal friction and high efficiency. Ball screws that applied to cnc machine can help to accurate movement of machine tools, ensuring precise cutting and shaping of materials.
What Granville Supplies
Granville supplies the original genuine HIWIN ball screws and developed our own ball screws, since 2008, we sales the factory warranty linear system parts, under the backup from Taiwan, we gradually became the top seller of Hiwin in the East of Asia. Knowing the market price difference, together we provide the best solutions for customers.
Ball screws
The product is mainly through the screw mechanism to convert the rotary motion into linear motion, so as to achieve the precise positioning of the table or cutting movement. Internal ball circulation as a transmission medium, the sliding friction of the screw and nut into rolling friction, thus significantly reducing transmission power, improve product accuracy, extend product life, the product is mostly used with linear slide rail, is a modern industrial equipment widely used products.
