What determines the accuracy of hydraulic presses

Cutting accuracy is an important part of measuring the effectiveness of hydraulic press processing, but laser cutting accuracy does not depend on the equipment itself, but is composed of many factors, mainly including.

1, the size of the laser beam through the spot after focusing

The smaller the spot of the focused laser beam, the higher the cutting accuracy, especially the smaller the slit, the smallest spot can be up to 01mm. head hydraulic press allows a maximum eccentricity of 40mm for concentrated load under nominal pressure of 500T. too much eccentricity makes the column easy to strain or other undesirable phenomena. 315 tons hydraulic press reduces mass and saves material. For typical parts such as automobile engine bracket and radiator support, the hydraulic formed parts are 20% to 40% lighter than the stamped parts; for hollow stepped shaft type parts, 40% to 50% weight can be reduced. Hydraulic press manufacturers improve strength and stiffness, especially fatigue strength, such as hydraulically formed radiator support, its stiffness can be increased by 39% in the vertical direction and 50% in the horizontal direction.

2, hydraulic press table alignment accuracy can determine the cutting repeatability

The higher the accuracy of the table, the higher the cutting accuracy.

3, the greater the thickness of the workpiece, the lower the accuracy and the larger the cutting slit.

Because the laser beam is conical, the slit is also conical, so 0, 3MM thick stainless steel than 2MM thick slit is much smaller.

4, the workpiece material has a certain social impact on the accuracy of laser cutting process.

Similarly, the cutting accuracy of stainless steel is higher than the cutting accuracy of aluminum, and the cutting surface is smoother.

Hydraulic press manufacturers processing size error is a common fault in the process of CNC machine tool shear processing. This failure not only affects the production efficiency, but also increases the production cost. The main reasons for processing size error are as follows:

1, the signal line is not normal. At this time we need to replace the control signal line.

2, equipment and computer system grounding leads to bad. At this time we need to ground the equipment and computer well.

3. Computer operation is not normal. In this case, you need to repair or replace the computer.

4. The computer's operating system is faulty or infected with a virus. Need to reinstall the operating system or virus detection.

5. The application software is not working properly. This requires reinstallation of the software and the driver software of the motion control card.

6. The power supply system power supply is unstable or by interference signals. At this time we need to remove the interference signal by adding a voltage regulator or.

7. The processing program is not prepared correctly. It is necessary to check and repair the processing program.

8. The processing parameters are not set correctly. Please reset the correct processing parameters.
