Should consider various Machining parts after machining, heat treatment and ancillary procedures, process routes in the preparation of the three co-ordination must be considered reasonable arrangement order. Arrangements for processing the order, including a number of elements such as: 1. Sequence of machining processes of the arrangements in principle; 2. Arrangements for heat treatment; 3. Arrangements supporting processes. Spindle bearing applications to adapt to the spindle lathes with ordinary box, which in mass production, the selection of rough gray iron casting material, the spindle bearing line of the manufacturing process used to concentrate the form of the production process to create the main considerations: 1) the use of high efficiency special equipment and process equipment, high production efficiency; 2) to reduce the number of the fixture is easy to ensure that the surface between the positional accuracy, but also reduce the auxiliary time; 3) less the number of industrial processes, the number of machine tools, operation and production workers in the area can be reduced, saving manpower and material resources, but also simplify production planning and organization. In the production and processing in the processing stage but also the division of the processing components in order to ensure the quality and rational use of equipment, manpower, spare parts are often impossible to complete the process in a fully processed, and the whole process must be classified as roughing, semi - three stages of finishing and finishing. Spindle bearing manufacturing process there are still some areas in which improvements need in order to meet the requirements of high productivity and improve the level of machining accuracy and assembly, which must constantly improve.
