Gantry surface grinding machine can complete mirror processing and grinding, especially suitable for precision machining of molds, cutting tools, connector connectors, semiconductors and other industries. At the same time, CNC products can complete the processing of cylindrical, outer circle, arc and other curves while ensuring the processing accuracy, and can achieve the multi-function of gantry surface grinder

Gantry surface grinding machine is actually also called plane grinding. Although the operation is more convenient, there are many types of processing, of course, it is necessary to cooperate with many fixtures to complete the station. Its accuracy is very high, if the grinding machine is digital, the accuracy can be guaranteed plus or minus 0.001mm. The grinding machine can process planes, positive angles, bevels, grooves, arcs, breaks, etc. The above stations can also be mixed processing (chute, bevel fault, bevel arc...) As long as it is through, it can be processed. High processing efficiency, high precision and low cost.

The outstanding advantages of gantry surface grinding machine processing are:

First, the processed parts have high precision and stable quality

The positioning accuracy and repeated positioning accuracy of the gantry surface grinding machine are very high, it is easier to ensure the consistency of the size of a batch of parts, as long as the process design and procedure are correct and reasonable, coupled with careful operation, it can ensure that the parts obtain high processing accuracy, and it is also convenient to implement quality control of the processing process.

Second, the degree of automation is high, which can reduce the physical labor intensity of the operator

The processing process of gantry surface grinding machine is automatically completed according to the input program, the operator only needs to start the knife, EDM machine to load and unload the workpiece, replace the tool, in the processing process, mainly observe and supervise the operation of the machine tool.

Third, the dimensions should conform to the characteristics of grinding machine processing

In CNC programming, the size and position of all points, lines and surfaces are based on the programming origin. Therefore, the coordinate dimensions are given directly on the part drawing, or the dimensions are quoted from the same datum as much as possible.

The control oil then pushes the main valve to reverse. The pilot valve is not reversed, and replacing the electromagnetic directional valve with an electro-hydraulic directional valve constitutes a new reversing method. The electro-hydraulic directional valve is composed of a pilot valve, a solenoid spool valve and a main valve, a hydraulic spool valve. This system controls the oil circuit by means of a pilot valve reversing switching. The direction of oil flow that controls the oil circuit does not change, the directional valve is always maintained at the original end, the direction of the main oil circuit does not change, and the workbench can always continue to move forward.

Gantry surface grinding machines with ideal control curves. The gantry surface grinding machine adopts the hydraulic transmission reversing system of electro-hydraulic proportional valve. It realizes the purpose of actively reducing the flow rate to reduce the speed and achieve smooth and impact-free commutation, and the ideal commutation can be achieved even when the working conditions change. This hydraulic transmission reversing system achieves good intelligent control of the displacement or speed of the output, so that the reversing process has a certain degree of controllability, so it has a very wide range of applications.

Hydrostatic rail hydraulic station

The gantry surface grinding machine adopts a fixed differential adjustable flow valve to adjust the floating amount of the workbench, so as to realize that the floating amount is basically the same under different load conditions, which greatly reduces the power of the main hydraulic station. The system has the characteristics of large bearing capacity, reliable and stable work, energy saving and environmental protection.

Main fuel tank

The gantry surface grinding machine has a unique structure, the temperature rise does not exceed 15 °C, and there is no need to install a cooling device on it; The system can realize shock-free commutation and smooth commutation; The power required by the main oil pump motor is only 11kw; The system has the characteristics of stable and reliable, low noise, energy saving and environmental protection.

Dynamic and static grinding head hydraulic station

The horizontal grinding head adopts the dynamic and static pressure bearing structure, which has high motion accuracy, no wear, long life, small starting power and large bearing capacity and good vibration resistance at high speed of the dynamic pressure bearing. The hydraulic station adopts constant pressure device to supply oil to the dynamic and static pressure grinding head, which has the characteristics of stable pressure, low noise and low temperature rise.

Gantry surface grinding machines have the following characteristics:

1. The gantry plane grinding machine adopts gantry layout, which consists of the bed, double column and beam to form the frame structure of the gantry. The hydrostatic guide rail used in the table and the impactless hydraulic system of the table have obtained national patents

2. The beam is equipped with drag plate and grinding head. The drag plate moves laterally along the beam guide rail, and the grinding head moves vertically along the drag plate. The steel-mounted guide rail on the beam moves in conjunction with the dovetail rolling guide block on the drag plate, making the guide rail wear-resistant and light-moving.
