Automatic cutting machine explains the composition of hydraulic cutting machine

How is the high precision of the automatic cutting machine achieved?
1. Processing procedures
The main surfaces of the guide column are the inner cylindrical surface the outer cylindrical surface. The processing procedures are: inner cylindrical surface: drilling-rough boring-semi-rough boring-rough grinding-fine grinding; for the outer cylindrical surface: rough turning-semi-finishing turning-rough grinding-fine grinding.
2. Electroplating hard chrome
After electroplating chrome, the mold workpiece have the following advantages:
1. The surface is flat, smooth easy to demold, to ensure the smoothness flatness of the product.
2. It will rust, there will be no rust spots.
3. The original parts are less deformed during the plating process, the surface chrome plating can enhance the hardness (HR65 above), high temperature resistance up to 500, corrosion resistance, acid resistance, wear resistance.
4. If the size of the part is in place, you can add a few c chromium to achieve the size.
5. According to the characteristics of the product, achieve visual three-dimensional effects to ensure the stable surface quality of the product.

3. Key technologies measures taken
1. The main surface is the inner cylindrical surface, with high dimensional tolerance small surface roughness Ra value. Measures taken: Divide the processing stages, the process route adopts: drilling-rough boring (expansion)-semi-finishing boring (reaming)-rough grinding-fine grinding-grinding; control the cutting amount; fully cool.
2. Since the dimensional tolerance of the outer cylindrical surface is high the surface roughness Ra value is small, the measures taken are: the requirements for the division of processing stages, selection of machine tools, control of cutting amount are the same as those for the inner cylindrical surface processing. In addition, the process route is: rough turning-semi-finishing turning-rough grinding-fine grinding.
1. Mechanical part of hydraulic cutting machine: It consists of the fuselage, working mechanism stroke adjustment device. The gantry hydraulic cutting machine also includes a saddle moving feeding device an automatic feeding device.
2. Hydraulic system of cutting machine: It consists of a hydraulic pump, a cylinder, a pressure valve, a directional valve, a filter, a fuel tank, a pressure gauge.
3. Electrical control part of the cutting machine: including electrical control circuits composed of components such as switches, relays, contactors.
