  • EDM Machining
        What's EDM Machining  Electrical Discharge machining is a Electrochemical machining method that use  the flash discharge of electric pulse to remove small particles from the surface of the workpiece.Thee processing principle is to utilize the high-temperature and high-pressure effects of electrode discharge and through repeated arc discharge corrosion,gasification and dissolution of metal electrodes and materials on the workpiece. During arc discharge corrosion, high temperatures and pressures are released, removing the material.The rule is to form an arc discharge between the workpiece and the electrode, discharge at the bottom of the contact between the electrode and the workpiece, and generate a thermal deposition process, which then processes the workpiece.     Characteristic of Electrical Discharge Machining    •Processing high hardness metal materials and material that is difficult to cut   •Extremely high machining accuracy and good surface quality, because of utilizing the effects of arc discharge corrosion, gasification and dissolution.   •Low temperature, without thermal deformation.   •CAD/CAM and CNC Technologies can be used to achieve digital control of machining , improving the level of machining automation.   •Achieve precise scratches and avoid damage that may cause hidden disputes.     Some Main Influence factors of EDM Machining   ⇒Qualit of the working fluild is one of the key factor affecting machining accuracy.   ⇒Electrode material and working current intensity can affect the processing effect, so metal materials with strong corrosion resistance are usually chosen   ⇒Workpiece materials are very important. Hard materials sush as tungsten alloys,steel, diecasting part can be processed by EDM machining. Soft materials are difficult to machine   ⇒Accuracy control of pulse time is the main parameter of Electrical discharge machining.   ⇒Shape ,Size, Surface finish and Machining accuracy of part will also affect the machining effect.   Some Typical application area of EDM Machining   Electrical discharg machining has high machining accuracy and efficiency, it also needs to pay attention to many details. In practical applications,appropriate parameter adjustments and equioment selection are required for differnt processing objects and requirements to achieve the best processing effect.EDM has many applications ,such as aviation ,aerospace, automobile, mold, electronics, medical equipment and watches .   •Mold manufacturing: EDM can accurately depict the complex curve and angle of the mold, and can realize precision micro machining and 3D machining,especially for the machining of some difficult and large molds. The processing method can greatly reduce the processing time of the mold, while also improving the accuracy and surface quality of the mold.   •Mechanical Manufacturing:EDM can process tiny holes, precise slits and other unique structural forms, which have an important impact on the performance of manufacturing mechanical devices. EDM can also process steel,stainless steel, alloy steel and other high hardness materials ,which can meet the processing requirements that can't be met by some traditional cutting methods in the field of mechanical manufacturing.   •Aerospace Field: The core parts of aeroengines need precise manufacturing that often involve high temperature, high pressure and other high strength effects, EDM can help to manufacture more  appropriate parts, thus improving the safety and reliability of aerospace equipment.   Electrical discharge machining can also be used for metal drilling and cutting , which is beyond the traditional machining methods.

  • wire cutting
    What's  Wire cutting ? Principle of Wire cutting: Using moving fine metal wires( molybdenum wire) as electrodes, workpiece is formed by pulse spark discharge cutting Using fine molydenum wire as a tool electrode for cutting, the wire storage cylinder causes the molybdenum wire to move forward and backward alternately, and the processing energy is supplied by pulse power supply. Pour the working fluid medium between the electrode wire and the workpiece. The workbench moves servo feed according to the Spark gap according to the predetermined control program in the two coordinate directions of the horizontal plane, so as to synthesize various curve tracks and cut the workpiece into shape Classification of wire cutting: ----Fast wire cutting, speed is 6-12mm/s ----Medium wire cutting, frequency conversion and multiple cutting functions on the basise of fast wire cutting ----Slow and high precision wire cutting, speed is 0.2mm/s Some Features of each  wire cutting      Speed  Precision Tolerance Surface Roughness Fast  Wire cutting  Fastest  lowest  +/- 0.01mm Medium Wire cutting Medium Medium +/- 0.005mm Slow and Precision Wire cutting slowest Highest +/- 0.002mm ⇒Characteristics of wire cutting technology     -Capable of procesing conductor an semiconductor materials with high hardness, high strength,high brittleness and high toughess   -Process of small irregular holes, narrow gaps and complex shaped parts   -Surface of workpiece is less affechted by heat-suitable for processing heat-sensitive materials; machining accuracy i high because of the conecntration of pulse energy in a very small range   -Electrode wire don't directly contact workpiece and has no macroscopic cutting force, which is beneficial for processing low stiffness workpieces   -Due to the narrow cutting seam generated during processing, the actual amount of metal erosion is very small, the material utilization rate is high ⇒Processing Scope of Wire Cutting Technology   -Machining of stamping dies,Including the processing of large,medium and small punch dies, such as convex molds, concave molds, fixed plates and unloading plates   -Processing of family cavity molds,powder metallurgy molds, bending molds,wire drawing molds.   -Processing templates, formming tools   -Processing fine irregular holes, narrow gaps and complex shaped parts,such as micro holes and narrow gaps in irregular hole spinnerets,jet components, laser devices, electronic devices   -Processing various special materials and structural parts, such as electonic devices, instruments, electric motors, clocks,as well as gears,thin shell devices   - Cutting of various conductive materials, especially rare and precious metals;Cutting off various special structural parts       Some Reasons For Affecting the surface roughness of Wire Cutting   The factors that directly affect the surface roughness of wire cutting mainly include electrode wire factors, electrical parameter factors, mechanical factors and workpiece factors:   ⇒Influence of Electrode Wire Factors   -Wire speed: Wire speed for fast wire cutting is 9-11m/s. If speed is too high, it will affect the smoothness of molybdenum wire operation. To ensure the surface quality of the processing ,wire speed should be reduced a much as possible   -Length of Molybdenum wire : Under constant processing conditions, increasing the effective working length of wire can reduce the number of commutations of the molydenum wire, reduce the shaking of the wire, promote the stability of the procesiing process and improve the surface quality of the processing   -Tension of Molybdenum wire: The discharge of wire cutting is 0.01mm.If wire is too loose and can't ensure a stable discharge gap during operation, it will cause unstable processing and poor surface roughness of the workpiece. Before processing, check whether the tightness of molybdenum wire is suitable. If it is too loose, tighten the wire.   ⇒Influence of Electrical Parameter Factors   -Selection of electrical parameters such as pulse width and processing peak current: The power supply used in discharge machining is a pulse power supply which is an important factor affecting the surface roughness of the machining. The surface roughness value increases with the increase of processing peak current, pulse width and pulse interval.During the processing, electrical parameters should be reasonably selected based on the processing situation.   -Feed Rate of Workpiece :During discharge machining,if the feed rate is adjusted too fast or too slow, it can cause frequent short circuits or open circuits, making the machining unstable and causing unstable stripes or surface erosion on the workpiece surface.   ⇒Influence of Mechanical Factors   -Positioning accuracy and sensitivity of the worktable: The movem...

  • Plastic 3D Printing
    Plastic 3D Printing Processes The three most established plastic 3D printing processes today are the following: Fused deposition modeling (FDM) 3D printers melt and extrude thermoplastic filaments, which a printer nozzle deposits layer by layer in the build area. Stereolithography (SLA) 3D printers use a laser to cure thermosetting liquid resins into hardened plastic in a process called photopolymerization. Selective laser sintering (SLS) 3D printers use a high-powered laser to fuse small particles of thermoplastic powder. used deposition modeling (FDM), also known as fused filament fabrication (FFF), is the most widely used form of 3D printing at the consumer level, fueled by the emergence of hobbyist 3D printers. This technique is well-suited for basic proof-of-concept models, as well as quick and low-cost prototyping of simple parts, such as parts that might typically be machined. Consumer level FDM has the lowest resolution and accuracy when compared to other plastic 3D printing processes and is not the best option for printing complex designs or parts with intricate features. Higher-quality finishes may be obtained through chemical and mechanical polishing processes. Industrial FDM 3D printers use soluble supports to mitigate some of these issues and offer a wider range of engineering thermoplastics or even composites, but they also come at a steep price. As the melted filament forms each layer, sometimes voids can remain between layers when they don’t adhere fully. This results in anisotropic parts, which is important to consider when you are designing parts meant to bear load or resist pulling. FDM 3D Printing Materials ABS for Many colors PLA PA12+CF TPU SLA 3D Printing Stereolithography was the world’s first 3D printing technology, invented in the 1980s, and is still one of the most popular technologies for professionals.  SLA parts have the highest resolution and accuracy, the clearest details, and the smoothest surface finish of all plastic 3D printing technologies. Resin 3D printing is a great option for highly detailed prototypes requiring tight tolerances and smooth surfaces, such as molds, patterns, and functional parts. SLA parts can also be highly polished and/or painted after printing, resulting in client-ready parts with high-detailed finishes. Parts printed using SLA 3D printing are generally isotropic—their strength is more or less consistent regardless of orientation because chemical bonds happen between each layer. This results in parts with predictable mechanical performance critical for applications like jigs and fixtures, end-use parts, and functional prototyping. Common 3D Printing Applications Additive manufacturing can be leveraged for both rapid prototyping and production in aerospace, medical, automotive, and other large industry sectors. Examples of typical parts, include: Form and fit prototypes Housings and enclosures Engine components Medical devices           Jigs and fixtures Fue injectors         Snap Fits           Heat exchangers and heat sinks Surgical Instrumentation
