For ceramic materials, due to their special physical and mechanical properties, initially they can only be processed by grinding methods. With the development of mechanical machining technology, various processes similar to metal machining can now be used for CNC ceramic machining.

Identification method of ultra-high molecular weight polyethylene Machininguhmw-pe is a polymer compound, which is difficult to process, and has super wear resistance, self-lubricity, high strength, stable chemical properties, and strong anti-aging properties, so it is distinguished between true and false polymers. When polyethylene, we must pay attention to its several characteristics, the specific identification method is as follows:

In the process of machining copper, the crystallization characteristics of copper alloys with different compositions are different, the casting performance is different, and the casting process characteristics are also different. Tin bronze: The crystallization characteristic is that the crystallization temperature range is wide and the solidification area is wide. Poor fluidity in casting performance, easy to produce shrinkage, not easy to oxidize. The process is characterized by directional solidification (sequential solidification) of thick-walled parts, and simultaneous solidification of complex thin-walled parts and general thick-walled parts. Aluminum bronze and aluminum brass: The crystallization characteristic is that the crystallization temperature range is small,

The performance of chipped stainless steel materials in stainless steel machining services is poor. In the actual cutting of chips, there are mainly the following problems: For the problem of work hardening, work hardening is mainly manifested in the following three aspects: First, due to the greater plasticity of stainless steel materials and strong deformation, when deformation occurs, the lattice Produce a larger strengthening factor. The second is the cutting problem. During cutting, austenite becomes martensite due to stability problems, and the hardness of martensite is too high. The third is that it will be affected by temperature when chopped. It has

The surface, shape and performance obtained by post-processing on the original form of stainless steel are suitable for industrial stainless steel products. Such as: commonly used machining flat plate, slitting, and then surface treatment, wire drawing, sand blasting, frosting, mirror surface, color coating, filming. Further in-depth machining includes laser, shearing, bending, grooving, stamping, welding, polishing, etc. Stainless steel coil Stainless steel coil slitting: divided into small coils on the basis of large stainless steel coils, generally used for pipe production, or stamping products, gaskets, parts, etc. Stainless steel slit Stainless steel flat plate: the large steel coil flat out the corresponding required

The service life of Swiss CNC punch press molds depends on factors such as reasonable mold structure, high manufacturing accuracy, good heat treatment effect, correct selection of punch presses, and mold installation accuracy of punch presses. For the neglected links, the following points should be noted: (1) The mold should be strictly inspected before installation and use, remove dirt, and check whether the guide bush of the mold and the mold are well lubricated. (2) Regularly check the turntable of the punch and the mounting base of the mold to ensure the coaxial accuracy of the upper and lower turntables.

Difficult tool unloading in CNC machining centers is one of the common faults, but due to its complicated structure, involving electrical, mechanical, pneumatic, hydraulic, etc., any failure of a loop link will cause machine tool unloading failure. This article takes the maintenance case of a VC1055 CNC machining center as an example, analyzes the common fault characteristics of tool unloading according to the spindle structure and principle of the CNC machining center, and discusses the repair of the faulty CNC machine tool according to the fault characteristics for reference. 1. Fault characteristics There is a VC1055 CNC machining center, which

The metal cutting process can produce the following three types of oil mist The oil mist is generated in different ways, and the particle diameter range is also quite different. Under normal circumstances, the oil mist produced by the mechanical atomization process mainly exists in the form of droplets, and the diameter of the droplets has a wide range, usually 2 to 10um. The oil vapor generated by evaporation will also form a very small diameter condensate suspension during the condensation process, and the particle size is usually below 2um. Purification principle of machine tool oil mist purifier The design

Advantages of brass  machining products

Method 1: Degreasing treatment. Wipe with absorbent cotton soaked in solvent. After removing oil, wipe with a clean cotton cloth several times. Commonly used solvents are: trichloroethylene, ethyl acetate, acetone, methyl ethyl ketone and gasoline. Method 2: Chemical treatment in the following solution after degreasing: concentrated sulfuric acid 27.3 (mass fraction, the same below), potassium dichromate 7.5, water 65.2, immersed at 60～65℃ for 10～30min, taken out, rinsed with water, and dried Or dry below 80℃. Or wash in the following solution and then dry: phosphoric acid 10, n-butanol 3, water 20, this method is suitable for phenolic-nylon glue, etc., the

The emergence of superplastic forming technology provides a new technical approach for the formation of certain titanium alloys with superplastic properties.Forming plan includes: forming device, mold material mold structure, heating method, charging method, wall thickness control and protective measures, etc. The main factors that should be considered in determining the forming plan are:
