The invention discloses a machining technology for round disks. The machining technology comprises the steps that firstly, a material is cut through a laser cutting machine, so that the shapes of the products are formed primarily through cutting according to a drawing size; secondly, the cut products are located and machined through a milling machine, and eight small round holes with the diameter being 1.5 mm are drilled at the position 2 mm away from the outer edge of each cylinder with the diameter ranging from 29.50 mm to 29.40 mm; thirdly, the products cut by the milling machine are located and machined, and four small round holes are drilled at the position 8 mm away from the outer edge of each cylinder with the diameter ranging from 29.50 mm to 29.40 mm; fourthly, stress treatment is conducted on the machined round disks; fifthly, deburring is conducted on the machined round disks, the surfaces of the machined round disks are polished, and the surface roughness of each round disk reaches Ra 3.2; sixthly, the round disks are inspected and put in storage, wherein during inspection and spot check, the appearance and the size are inspected, 10 round disks are selected for appearance inspection, and six round disks are selected for size inspection. By the adoption of the machining technology for the round disk, production requirements can be met, the precision and the strength of the produced round disks are improved, the produced round disks meet requirements, the defective rate is reduced, and production cost is reduced.
