At present, the tapping method must be installed in different sizes of die plates to meet the needs of the work, which brings inconvenience to the operator. To this end, a retractable plate holder was designed (see photo). As long as the two screws are adjusted, 4 to 5 different dies can be in.......
The large number of applications of CNC machine tools has greatly improved the manufacturing capacity of the manufacturing industry and the quality level of the products. However, most of the operators of CNC machine tools are transferred by the operators of ordinary machine tools. Only a smal.......
The "tool" of a wire cutting machine is a wire, the material is molybdenum, commonly known as molybdenum wire. The melting point of molybdenum is very high (2622 ° C), second only to tungsten (3410 ° C), but the elongation of molybdenum is 8 times that of tungsten. Therefore, m.......
Electric spark cutting is a method of forming a linear electrode. Because it simplifies the processing of molds (especially complex molds) and shortens the production cycle, it is widely used in the mold manufacturing industry. However, due to the gap between the structural design, manufacturi.......
The M7475B surface grinder is a circular electromagnetic table, a vertical grinding head, and a high-efficiency grinding machine that uses a grinding wheel end face for grinding. In the course of use, it is easy to encounter fatigue wear when the electromagnetic suction cup and the withdrawal s.......
Our factory needs to use a large number of hexagonal punches (Figure 1). In order to efficiently process this hexagonal punch, a high-efficiency fixture was designed and manufactured (Fig. 2). The inner hole and the hexagonal punch tail circle Φ20mm are clearance fit, and the gap is 0.005~0.......
With the needs of urban coal gasification construction, the specifications and varieties of gas pipes have been increasing, and the original pipe cutting machines have not adapted to the needs of production development. We designed and manufactured a multi-type pipe cutting machine (semi-autom.......
The commonly used graded carbide indexable inserts are laser-treated and tested in the laboratory. The surface roughness is reduced and the quality is improved. This is especially true when turning stainless steel. First, the test situation Select the commonly used YT15, YG6, YW1 three brands .......
Our factory produces a series of internal thread parts in large quantities. The thread has a screw length of 20mm or more and requires 100% inspection. When the parts are machined with internal threads on the lathe, it is necessary to measure the threaded plug gauges several times, which consu.......
Turning spheres are often encountered in the machining of metal parts. In the processing tasks we undertake, a number of spheres are designed with a sphere of φ14=_(-0.160)~(-0.060)～φ24=_(-0.117)~(0.005)mm. To this end, we have designed a relatively simple knife row that has been .......
The part of our factory producing 35 steel grade 10 M8 ~ M24 nut is: 镦 shape → normal fire → reaming → tapping → quenching → tempering. Since the national standard of 6H thread does not specify the amount of deformation after thread quenching and the re.......
When we cut the ring magnet (Fig. 1) into a sector magnet (Fig. 2), it can only be cut with a diamond grinding wheel because the workpiece is brittle. For this purpose, we have designed the clamp (Fig. 3). In use, the workpiece 4 is placed on the pressure seat 7, and then the pressure cover 3 .......
