Dragon Gate milling machine is referred to as Longmen milling, which is a door -style frame and a horizontal long bed.The dragon door milling machine can be used to process the surface at the same time, and the processing accuracy and production efficiency are relatively high. It is suitable for the plane and slopes of large -scale workpieces in large -scale production and large -scale production.How to safely operate Longmen milling? How to repair the fault of Longmen milling machine?
Longmen milling machine performance characteristics
Longmen milling machines have sufficient rigidity, high efficiency, convenient operation, simple structure, and comprehensive performance.
Its specific performance characteristics are different according to the types, models and manufacturers, and have a lot to do with the technology used.Taking the SK series three -axis Dragon Gate milling as an example, its performance is characterized by:

Dragon Gate milling machine operating procedure
1. Clamp the work of the work.Use a general wrench to not add a tube to avoid slipping the injury.
2. The tool must be clamped, otherwise it is not allowed to drive.
3. Before work, check the operation of the machine tool transmission and install the barbed baffle to operate.
4. Milling various workpieces, especially when coarse milling, should start slowly cutting.
5. When the mobile workbench and blade frame, the fixed screw should be released first.
6. When loading and unloading, you should use a copper hammer or mallet to prevent the knife from flying out of the injury.
7. In cutting, it is not allowed to change and adjust the tool, and it is forbidden to touch or measure the workpiece by hand.
Dragon Gate milling machine repair
Dragon Gate Milling Term Rail Repair: Most of the machine tool guide rails are made of steel or cast iron. Such a guide rails are scratched and they should be repaired, otherwise the scratches will be expanded and even affects the use of machine tools.In the long -term use of the machine tool guide rail and other friction, due to different degrees of friction between the two contact surfaces, the friction sub -surface is worn to varying degrees of wear, which will affect the processing accuracy and production efficiency of the machine.The repair of machine tools and other wear areas usually uses metal plates and polymer materials inlaid or replacement. It not only requires a large amount of accurate processing and manufacturing, but also often requires manual scraping on the processing surface.long.
Solution: Use the international advanced high -molecule 2211F metal repair material to repair the Dragon Gate milling machine guide rail scratching. It only takes a few hours to restore the guide rail scratches and put it into use.Practice has proved that this method is simple to operate, save time, repair quality, and low cost.Using its unique adhesion, excellent pressure resistance, oil resistance, and abrasion resistance can provide a long -term protective layer for components, which can effectively solve the problems that cannot be dismantled due to the problems that cannot be solved by traditional maintenance methods.The performance of the equipment has been improved, the cooperation of the components has been improved, the normal operation of production is guaranteed to the greatest extent, saved a lot of time and funds for customers, and provided long -term and good guarantees for the normal operation of enterprise equipment.
Repairing principle: The polymer composite material is a material made of polymer polymer, metal or ceramic ultra -fine powder, fiber, etc., and compounds under the action of curing agents and solidification promoters.Various materials have grown up and supplemented with each other, producing synergistic effects, making the comprehensive performance of composite materials better than the original component material.With strong adhesion, mechanical properties, and chemical corrosion resistance, etc., it is widely used in the repair of mechanical wear, scratching, concave pits, cracks, leakage, sand eye for casting, and various chemical storage tanks of metal equipment, Chemical anticorrosive protection and repair of reaction tanks and pipelines.
Reunion technology:
1. Use oxygen-acetylene flame to bake the site (master the temperature to avoid surface annealing), bake out the oil on the metal surface of all year round, and bake until there is no spark.
2. Treat the scratching site with the surface of the corner grinding machine, polish the depth of more than 1 mm, and polish the groove along the guide rail.The drilling holes at both ends are deepened and the stress is changed.
3. Wash the surface with dehydrated cotton dipped acetone or water -free ethanol.
4. Apply the uniform 2211F to the scratching surface; the first layer should be thin, uniform and all overwrite the scratch surface to ensure the best bonding of the material and the metal surface, and then apply the material to the entire repair site. Repeat repeatedlyPressing to ensure that the material is filled with and reaches the required thickness, making it slightly higher than the surface of the rail.
5. It takes 24 hours to achieve the performance of the material completely under 24OC. In order to save time, the temperature can be increased by the halogen tungsten lamp. The temperature will be shortened by half of the temperature, and the best curing temperature will be 70oC.
6. After the material is solidified, use fine millstones or scrapes to repair the materials higher than the surface of the track, and the construction is complete.
Thermal deformation
Reason: Under the influence of the heat source inside and outside, the components of the Dragon Gate milling machine will deform varying degrees of heat, causing the relative motion relationship between the workpiece and the tool to be broken. For the dragon door milling machineControlled, the effect of heat deformation is even more serious.
In order to reduce thermal deformation, the following measures are usually used in the structure of the dragon door milling machine.
1: After controlling temperatures, after taking a series of measures to reduce thermal source, the heat deformation will improve.However, it is usually very difficult to completely eliminate the internal and external heat sources of Longmen milling machines, or even impossible.Therefore, it must be controlled by good heat dissipation and cooling to reduce the effects of heat sources.Among them, the more effective method is to force cooling at the heating site of the dragon door milling machine. It can also be consistent with the temperature of each point of the Dragon Gate milling machine at the low temperature part of the dragon gate milling machine, which can reduce the warning deformation due to temperature difference.
2: Reduce the main thermal source of thermal deformation when the heat of the heating dragon door milling machine, should be separated from the host as much as possible from the host.
3: The improvement of the spindle box for the main axis box of the dragon door milling machine should try to make the thermal deformation of the spindle occur in the vertical direction of the cutting tool.This can reduce the effect of the spindle thermal deformation on the machining diameter to a minimum.In terms of structure, the distance between the center of the spindle and the ground should be reduced as much as possible to reduce the total amount of thermal deformation. At the same time, the temperature rise of the main axis box should be consistent, and the tilt of the spindle is avoided.
4: Under the same heating conditions, the dragon gate milling mechanism has a great impact on thermal deformation.For example, the single -pillar mechanism used by Longmen milling machines may be replaced by the double -pillar mechanism.Due to the left and right symmetry, except for the translation of the vertical direction after the heating of the double -column mechanism, the deformation of other directions is very small, and the axis movement of the vertical direction can easily use a coordinate correction amount to compensate.
