1. 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 ensures that there is no loss of accuracy 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 reducing the surface finish and accuracy of the workpiece. 2. 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 high - quality bearing design and uses high - speed bearings to achieve high precision. - It has a dust - proof seal design to prevent cutting dust from entering the bearings, thus extending the service life. - It is specially designed for lathes in medium - speed, medium - load environments. - It has good balance performance, runs smoothly, and can effectively perform turning operations. - It is very suitable for supporting your workpiece at the tailstock end of the lathe. 3.
