The first one is the cooperation between the tool holder and the spindle. Because the measurement gap occurs during clamping, sometimes there are chips or dirt on the taper shank. Therefore, the positioning of the taper shank will be different every time. Therefore, the imbalance between the tool and the tool holder should be measured before or during use, or the tool can be replaced or moved to reduce the imbalance. Moreover, the above points should be repeated frequently to check the accuracy of the blade to achieve balance.
        The second point is to choose high-quality blades and tool holders, use short blades and lighter blades as much as possible, and regularly check the blades and tool holders to check the degree of wear between them to see if there is any deformation sign. Another point is the technical requirements of blade imbalance, that is, the cutting force and the balance of the machine tool are also key factors in the process of use. To find the best balance method, you can choose different unbalance values ​​for trial operation several times. For example, you can start from the unbalance value slowly decrease until the balanced blade is repeated several times to further improve the work quality.
        When cutting at high speed, we should choose a tool system composed of a symmetrical tool and a tool holder as much as possible. If there are different tool systems, we can first heat the tool holder to expand its empty space. Was clamped. In fact, the most important point for high-speed cutting is to find the best method and the best state to fix the blade. The purpose of this is to make the blade less active.

        The paper cutter is used to handle the paper cutting needs in the late printing. From the development of mechanical machines to tape-controlled machines, to the development of microcomputer program control, color display, full-image operation guidance visual processing and computer-aided cutting external programming and editing production data, the cutting system makes the production preparation time shorter. The cutting precision is higher, the labor intensity is lower, the operation is simple and safe.
        The cutter's optimized heavy-duty frame design, precision processing, stable performance, and durability; the cutter uses new high-integration and high-stability components, and the original electronic knife position indicator line to ensure the reliable operation of the cutter; touch key panel , Two-handed interlocking device, automatic reset function to ensure absolute safety. The use of high-speed steel blades is sharp and durable; the unique fault self-detection function makes your operation more handy! In the field of paper cutting, regardless of quality or appearance, the products produced by our company have always been in a leading position in similar domestic industries. High cutting performance, suitable for cutting labels, carbon paper, hardcover books, etc.

        The new blade of the paper cutter or the blade that is not more than 20mm sharpened, hang the two holes of the blade on the upper knife pin when using the knife, and use the second row of holes to fix it with the knife bed.
       When the blade is sharpened more than 20mm, use the first row of holes to fix it with the tool bed, and at the same time, fix the spare parts: two pads between the tool bed and the blade, and use M6 screws to fix it. Use 20mm pads on both sides. Also check that the pad must be below the sliding surface of the knife bed.
        Between each 20mm, adjust the adjustment nut of the drawbar of the cutter bed and adjust the height of the cutter blade to meet the requirements.
        During the use of the blade, in order to make the machine work more flexible, you can often apply paraffin or talc powder to the blade edge. Since talc powder and paraffin can reduce the friction between the two contacting objects and can make the cutting smoother, this can be extended. The service life of the blade edge.
        The blade is the main part of the cutting, and its sharpening angle and sharpness have a great influence on the cutting accuracy. For different varieties and different materials, the sharpening angle is different. In general, when cutting hard paper, to overcome the larger cutting resistance, the blade sharpening angle should be larger (between 22 and 25 °), if a blade with a smaller blade angle is used for cutting at this time Hard paper, because of the thin blade of the blade, cannot overcome the cutting resistance of larger paper, deform the blade, and cause insufficient cutting at the lower part, which affects the cutting quality. Generally, when cutting soft or thin paper, the angle of the blade should be between 16-21 °.
        The sharpness of the blade edge is also a factor that affects the cutting accuracy. According to the difference between the cut product and the working time, the number of grinding times of the blades is different. Generally, the continuously cut blades need to be replaced with new sharpened blades within 2-3 hours. In specific use, you should determine a reasonable number of blade sharpening times according to your own cut products.
        If the unsharp blade is still in use, it will cause damage to the machine (such as the safety bolt is easy to break), shortening the life of the machine.

         In the paper processing industry, we know that it has a lot of influence on the quality of paper cutting. One of the more important is that the pressure of the hydraulic paper cutter will also affect the quality of the paper.
        Especially when the hydraulic paper cutter is in operation, its pressure must not change at will, otherwise it will affect the cutting quality of the paper product. Why does the pressure of the hydraulic paper cutter affect the paper products?
        This is mainly because the transmission power of the hydraulic equipment of the hydraulic paper cutter is relatively large. Wide range of speed regulation, excellent balance performance, high degree of automation, easy operation and many other advantages, so it is used by the majority of paper processing manufacturers. When using this kind of equipment, if the pressure is set incorrectly, it will affect the paper product. For example, excessive pressure will cause the paper product to compress and deform, and the pressure will be too small to reduce the cutting accuracy. Therefore, when using the hydraulic paper cutter, the pressure of the equipment must be adjusted reasonably.
        Of course, there are a variety of paper cutters capable of pressure control on the market. Compared with manual adjustment, the pressure accuracy of the program-controlled hydraulic paper cutter is more accurate. This is also one of the mainstream products in the paper processing industry equipment market.

        The ordinary hydraulic paper cutter will not slip if the oil pipe is not leaking. There are three cases of electric:
        First, with an electromagnetic clutch, when the knife holder returns to the top, the clutch will pull in, ejecting the mechanical arm with a hook, locking the knife holder (hanging, a mechanical mechanism) to prevent the knife holder from falling off. If this is the case, check the clutch action and mechanical mechanism here to see if there is a problem.
        Second, the lower knife motor itself has a brake (brake). At the rear of the motor, this situation should be the brake (brake) is not working. Check whether the brake of the motor is defective, and then make a judgment to see if it needs to be replaced?
        Third, the mechanism without knife lock and without brake, completely rely on the photoelectric sensor or limit switch to control the position of the tool holder stop, so the stop position will not be very accurate. Once the sensor fails, either the machine will not move, or it will be The non-stop movement is quite dangerous.
