steel-inlaid guide rail wire cutting machine finish is composed of two elements, one is the size of a single discharge corrosion pit, its RZ is usually between 0.05μ-1.5μ, which is secondary to the cutting finish. The second is the convex and concave stripes caused by commutation, its RZ is usually between 1 μ-50 μ, and it is possible to be larger than 0.1MM, which is the most important factor in the finish of steel-inlaid guide rail wire cutting machine. At the same time, it is accompanied by black and white stripes, giving people a strong visual impact.
It is easier to control the pit size caused by a single discharge by reducing the energy of a single pulse. Only the single pulse energy is small to a certain extent, resulting in a thicker workpiece cutting, or even a non-spark state of only short circuit and no discharge, which is similar to the fine specification in EDM, resulting in extremely low efficiency and unstable processing with poor chip removal ability. Moreover, the RZ caused by the discharge pitting is not in the same order of magnitude as the RZ caused by the commutating fringe, so it is most important to control the RZ accompanying the commutating fringe. The accuracy of the guide wheel and bearing, and the constancy of the tension in the up and down running cause the inconsistent motion track of the silk up and down. This mechanical factor is the main reason for the commutation.
Take the following measures to improve the finish to some extent:
1. Properly reduce the pulse width and peak current, that is, reduce the size of the pit.
2, the guide wheel and bearing to maintain good accuracy and smooth operation, reduce the silk shake, silk jump, so that the silk trajectory to maintain a line of displacement to minimize.
3, the wire to maintain the appropriate tension, and adjust the guide wheel and feed block, so that when the wire up and down, the tension in the working area remains unchanged.
4, the silk should not be too tight, the water should not be too new, the new water is certainly beneficial to the cutting efficiency, but the cutting finish is not new water *.
5. Add a splint on each side of the thin workpiece so that the commutation stripes are buffered within the range of the splint.
6, XY movement is stable, accurate, good fidelity with movement, and non-blocked crawling is also extremely important.
7, maintain a stable loose frequency tracking.
8, the appropriate amount of cutting again or multiple cutting, in the case of a small amount of cutting the cutting surface sweep, dimensional accuracy and finish will have a beneficial effect, even sweep three times, will basically remove the commutation fringe, as long as the machine repeatedly positioning accuracy is high, the appropriate amount of progressive processing, will make the cutting surface finish increased by one to two orders of magnitude, The effect is similar to slow walking wire, and the time is not too much, which is one of the strengths of fast walking wire cutting machine.

With the rapid development of society, every day can come into contact with a variety of packaging products, such as cartons, bags, etc., these are custom Others products Printing. Due to the improvement of living standards, the quality requirements of color box packaging are getting higher and higher, and there are also some problems. When custom Others products Printing, it is necessary to unify the overall color of the packaging box when printing the background color. At this time, if there are different colors, even the printing of the entire packaging will fail. What is the reason for this? Let's answer the following questions:
First of all, there are many different colors of the ink used, in order to solve the color difference of the offset printing ink on the plastic film, the offset printing ink should be used with relatively stable quality and small color difference. For printing products, try to use the same manufacturer of ink and printing products, and try to use the same batch of ink produced by the same manufacturer, some special color box packaging boxes need to be printed with spot color, so you need to adjust the ink once.
The second is that the ink circulation is not smooth, the ink circulation system is used to keep the ink circulation smooth, in order to ensure the convenience of adding diluents and new ink, the ink has good quality and fluidity.
Third, the printing speed is inconsistent with the ink drying speed, the printing speed and the ink drying speed will directly affect the inking rate of the color box packaging, so the change of the printing speed and ink drying speed will cause the change of the ink color on the color box packaging.
If the Printing quality is not good, it is easy to reduce the grade of the entire product, so if the product quality is poor due to poor printing quality, this is actually a pity, if the above three problems are solved, then there will be no color difference problem.

With the development of the manufacturing industry, the production level of the machinery industry continues to improve, people's requirements for CNC machine tools are getting higher and higher. Full Automatic Hydraulic Machine is a kind of machine tool mainly controlled by digital program, which aims to convey digital instructions to the electronic control system to achieve accurate adjustment of motion control. The basic construction includes the headstock, cutting bed, positioning system and hydraulic control system, in which the headstock is responsible for transferring power to the tool, the horizontal and vertical axes are responsible for rotating the workpiece to various angles, the positioning system is responsible for positioning and position detection, and the hydraulic control system is used to drive and control various workflows.
The workflow mainly includes:
1. Boot link: After boot, it is necessary to carry out self-check function to confirm that the components are connected and work normally. In addition, it is necessary to set various parameters such as tool radius, number of workpieces, rotation direction, etc.
2, processing link: the processing of the workpiece is divided into multiple steps, such as: select the appropriate tool, processing depth and parameters, rotation direction, cutting speed and so on. According to the set processing program, the control system starts the servo drive to control the motor on each shaft, and locates and controls it through the computer instruction. The CNC system controls the servo system of the machine tool to run automatically according to the preset program, including feed, tool change, machining and other processes. In the process, the spindle rotates quickly and at high speed, ensuring efficient cutting.
3, feedback and adjustment: the CNC system will detect the status and position of the workpiece in real time, while collecting the relevant information in line with the processing, and automatically adjust the processing according to the feedback results to ensure the processing accuracy and consistency.
4, complete the processing task: wait until the completion of the operation, through manual inspection and quality detection, and finally ensure that the workpiece meets the design requirements. If the machining is not qualified, the operator will formulate appropriate adjustment measures and re-process.
