When a factory manufactures a washing machine, the parts shown in Fig. 1 need to process 12-φ40mm and 48-M6 holes. If one piece of wire is used to machine one piece, it takes 10~12h, and the technical requirements are high, and the quality is difficult to guarantee. We designed and manufactured

This is a very realistic discussion. Although the software market has giant companies such as CATIA, UG, PTC, etc., there is no such thing as a monopolistic desktop operating system like Microsoft's Windows, so there are a lot of forests like Solidworks, Cimatron, Powermill, Mastercam. The vario

Our factory MQ1350A cylindrical grinding machine is open when it is used for a long time, and the following faults occur in the hydraulic part. 1. When the grinding head is fast-feeding and resetting is not allowed to grind, the spark suddenly increases. The parking check finds that the grinding wh

There are usually a plurality of geometrical tolerance requirements on the crankshaft. The completed crankshaft is generally divided into factory assembly or factory assembly. Due to different assembly methods, the test methods for the tolerance of multiple measured shapes on the crankshaft will al

The gas cylinders we use are often incapable of inhaling because of the looseness of the cowhide bowl, which makes people feel inconvenient, even after the repair, it feels reciprocating. According to experience, I replaced the cowhide bowl with an O-ring (see picture), and then modified a piston t

Our factory has implemented methods such as cyclic oil change, sampling and oil change, and test tube sampling for oil change. These methods have their own shortcomings. Through practice, our factory has made the oil sample tool from the bottom of the fuel tank and oil drum, which is introduced as

The internal spline eccentric shaft on the CJ-12 tractor produced by our factory, as shown in the figure, is used to process the workpiece. In the past, we processed according to the usual method, which is difficult to correct, low in work efficiency and poor in quality. To this end, we designed an

The development speed of CNC system of modern CNC machine tools is changing with each passing day, the system work is more and more stable and reliable, and the failure rate of the system itself is getting lower and lower. However, the control system must establish the coordinate system before star

In the past, we processed the large-diameter rubber washer by clamping a round wooden board on the three-claw self-centering chuck of the lathe, and cutting the square rubber sheet larger than the outer diameter of the washer with the nail or nail to the end of the board. On the top, it is cut with

With the need of market competition, the Dongfeng Motor Co., Ltd. tool and die branch factory in the external undertaking tasks, the production of cam processing tasks increased. Since cams are a type of parts that are often used in various machines with a high degree of automation, there are many

EdiTasc is a universal CNC software for various control boards of MOVTEC. It is not only an ideal CNC software including drilling machine, milling machine, boring machine, engraving machine and machining center control function, but also a highly open development platform, which can directly contro

Based on the practice and on the basis of the general round body forming turning tool, we deduced the graphic method and calculation method for the contour design of the circular body forming turning tool for machining the inner hole, which greatly improved the design efficiency, which is as follow
