Machine specifications should include model, machine specifications and machine main motor power. Under the premise of determining the content of the process, the choice of the model is clearer. For example, the processing of rotary parts is mainly for the selection of equipment such as lathes, turning centers, CNC grinding machines, etc.; the processing of the box should be mainly vertical or horizontal machining centers. CNC machine tool processing has been developed into a wide variety of products that can be widely selected. The simpler and better, the machine model should meet the requirements of the processing technology. For example, turning centers and CNC lathes can machine shaft parts, but a turning center that meets the same processing specifications is several times more expensive than a CNC lathe if there are no further process requirements. The selection of CNC lathes should be reasonable. In machining cavity mold parts. The same size CNC milling machine and machining center can meet the basic processing requirements, but the price difference between the two machine tools is 20% to 50%. Therefore, in the mold processing, the process of changing the tool can be used to arrange the machining center and fix a tool. An optional CNC milling machine for long-term milling. The most important specifications for CNC machine tool machining are the stroke range of several CNC axes and the spindle motor power. The three basic linear coordinate (X, Y, Z) strokes of the machine tool reflect the machining space allowed by the machine. The two coordinates (X, Z) in the lathe reflect the size of the allowable rotor. In general, the contour size of the machined workpiece should be within the machining space of the machine. For example, if the typical workpiece is a 450 mm × 450 mm × 450 mm case, then a machining center with a work surface size of 500 mm × 500 mm should be selected. The choice of a work surface that is slightly larger than a typical workpiece is considered for mounting fixtures. The machine tool table size and the three linear coordinate strokes have a certain proportional relationship. For the above-mentioned workbench (500 mm × 500 mm), the x-axis stroke is generally (700-800) mm, and the y-axis is (500-700). The mm and z axes are about 500 to 600 mm. Therefore, the size of the work surface basically determines the size of the processing space. In some cases, the workpiece size is allowed to be larger than the coordinate stroke. In this case, the machining area on the part must be within the stroke range, and the allowable bearing capacity of the machine table and the space interference of the workpiece with the machine tool exchange tool must be considered. A series of problems such as interference with accessories such as machine guards. The main motor power of CNC machine tools can also have various configurations on the same type of machine tool, which generally reflects the cutting rigidity and high-speed spindle performance of the machine. For example, a light machine tool may be 1 to 2 less powerful than a standard machine tool spindle motor. At present, the spindle speed of general machining center is (4000 ~ 8000) r / min, high-speed machine tool vertical machine can reach (20,000 ~ 70,000) r / min, horizontal machine tool (10000 ~ 20000) r / min, its spindle motor power also Doubled. The spindle motor power reflects the cutting efficiency of the machine tool and reflects the cutting rigidity and the overall rigidity of the machine tool from the other side. In modern small and medium-sized CNC machine tools, the mechanical shifting of the headstock has been used less frequently, and often the AC variable speed motor with a large power is directly connected to the spindle, and even the electric spindle structure is adopted. Such a structure is limited in torque at a low speed, that is, the output power of the speed-regulating motor is lowered at a low speed. In order to ensure a low-speed output torque, a high-power motor is required, so that the spindle machine motor of the same-standard machine tool numerical machine machine is several times larger than that of the ordinary machine tool. When there are a large number of low-speed machining on some typical workpieces of the unit, the low-speed output torque of the selected machine must also be checked. The light machine tool is definitely cheaper in price, and the user is required to comprehensively select the machine tool according to the size of his typical workpiece blank, the cutting ability (metal removal amount per unit time), the required machining accuracy, and the actual tool configuration.

The pump consists of a pneumatic motor and a hydraulic pump, which are connected together. The pneumatic motor is powered by compressed air and converts the energy from the air into mechanical motion. This motion is then transferred to the hydraulic pump, which converts it into hydraulic pressure.
The hydraulic pressure generated by the pump can be used to power hydraulic cylinders, motors, or other hydraulic devices. It is commonly used in industries such as automotive, construction, manufacturing, and mining.
One of the advantages of a pneumatic hydraulic pump is its ability to generate high pressure with relatively low energy input. It is also compact in size and can be easily transported and installed. Additionally, it does not produce any emissions or require any fuel, making it environmentally friendly.
However, pneumatic hydraulic pumps can be noisy and require a constant supply of compressed air to operate. They also have limitations in terms of the maximum pressure they can generate.
Overall, a pneumatic hydraulic pump is a versatile and efficient device that combines the benefits of both pneumatic and hydraulic systems. It is widely used in various industries for its ability to generate high pressure and power hydraulic equipment.
