Figure 1 shows the decorative panel parts (material: Q235A) with a curved surface of R61.9_0~(+0.15)mm. It is usually milled on a milling machine using a special non-standard milling cutter, or designed and manufactured in a vertical punching machine. It was punched out. However, due to limite …
The workpiece shown in Figure 1 is often encountered in production. Grooves or raceways are formed in the inner hole or outer circle of such parts, and the diameter d is measured by a universal tool, and the measurement error is large. Figure 2 shows the special tool we used to modify the vern …
The steam turbine generator set produced by our factory has a variety of bearing tiles, and the spherical surface has a diameter of 300-650mm. This large bearing tile has a high dimensional accuracy requirement, and the spherical surface roughness is Rα0.8. When trial production, the spheri …
To ensure the machining accuracy requirements of the multi-channel valve body shown in Figure 1 (Figure 1), we designed (Figure 2) the valve body fixture. The workpiece is positioned on the indexing rotary disk 2 with an end face and an inner hole of φ70 mm, and the workpiece is clamped by …
Production of small pin, shaft and sleeve-shaped workpieces, after grinding at both ends or at one end, chamfer the outer or inner edge of the hole. The conventional positive working method is to use a lathe to clamp the three-jaw chuck, which is a thin workpiece, which is easy to deform and p …
After turning the workpiece shown in Figure 1, we quenched and re-grinded the φ60js6 outer circle and the two φ42N7 bores, resulting in high reject rate. To this end, we designed a center-mounted grinding fixture on the M1432A cylindrical grinding machine (Fig. 2). The coaxiality pass …
MasterCAM 8.X is a CAD/CAM software system based on PC platform developed by CNC Software of the United States. MasterCAM 8.X includes four modules: Design, Lathe, Mill and Wire, a powerful set of software that combines design and manufacturing capabilities. In order to transfer the automatica …
Recently, China North Industries Co., Ltd. of China Ordnance Industry Group independently innovated and delivered a good report, successfully produced 30/40 grain high-grade diamond on domestic six-sided top press. After national inspection and user evaluation, all performance indicators hav …
The φ5.64m shield tunneling machine manufacturing project undertaken by our factory has urgent tasks and short cycle. Cylinder processing is a key part in the manufacture of shields, in which the single-stage jack cylinder (inner hole φ250×1873mm, 35 steel) is solid. Forgings. Obvi …
