A. A lathe center is a tool ground to a point, used to precisely fix a workpiece on the axis. Its included angle is 60 degrees. The main purpose of the center is to ensure the concentricity of the machined workpiece; this helps to reduce accuracy loss when the workpiece is transferred between different machining processes. A part can first be turned on a lathe, then sent for quenching and tempering treatment, and finally ground on a cylindrical grinder using the center for positioning. The center is also used to support longer workpieces because the cutting force during machining may cause excessive bending of the workpiece, thereby affecting the surface finish and accuracy of the workpiece. B. Features: - The conical part is made of T10 steel, with a quenching hardness of 55 to 60 Rockwell hardness (HRC). The main body is made of 40Cr steel, with a quenching hardness of 45 to 50 Rockwell hardness (HRC). - It adopts a bearing design and uses high - speed bearings to achieve a certain level of precision. - It has a dust - proof seal design to prevent cutting dust from entering the bearings, which may extend the service life. - It is designed for lathes in medium - speed, medium - load environments. - It has relatively good balance performance, runs smoothly, and can perform turning operations. - It is suitable for supporting your workpiece at the tailstock end of the lathe.
