Tint inspection is a method of nondestructive testing. It is a surface inspection method, mainly used to detect surface damage such as cracks that cannot be recognized by the naked eye, such as the detection of stainless steel near surface defects (cracks), pores, porosity, stratification, penetration and fusion defects (also known as PT inspection). It IS SUITABLE FOR INSPECTING COMPACT METAL MATERIALS (WELDS), NON-METALLIC MATERIALS (glass, ceramics, fluorine plastics) and defects (cracks, pores, etc.) on the surface of products. The basic principle of color detection: the surface of the material is coated with colorant, and the colorant penetrates the damaged part. Rinse the colorant off the surface after a period of time. The surface that has been cleaned is coated with a developer, and the damaged area can be seen clearly because the colorant has penetrated into it. The capillary phenomenon is mainly used to make the permeate into the defect, and the surface permeate is removed by cleaning agent, and the permeate remains in the defect, and the capillary action of imaging agent is used to adsorb the residual permeate in the defect to achieve the purpose of testing the defect. Pre-clean the workpiece surface Before applying penetrant inspection surface, should use cleaner clean surface clean, makes checked surface without oil, rust, chip, and other dirt lacquer layer (such as inspection of weld, on the surface of weld and weld edge should not be oxided surface scale, welding slag, spatter, etc), and then, makes the surface of the workpiece tested to fully dry. Dye penetrant After evenly spraying the surface of the treated and clean workpiece with osmotic agent, permeate it for 5-15 minutes. Cleaning and drying After 5-15 minutes of penetration, and before applying the imaging agent: (1) Use a cleaning agent to clean the permeant sprayed on the surface of the workpiece, so that the inspected surface should be clean; (2) Wipe dry with clean gauze or dry naturally at room temperature Note: when removing excess penetrant, over-cleaning or insufficient cleaning should be prevented (ensure that there is no penetrant on the surface of the workpiece). imaging After fully shaking the developing agent, spray evenly on the surface of the inspected workpiece (cleaned and dried workpiece) at a distance of 150mm-300mm, spraying Angle is 30° -40 °, and the developing time is not less than 7 minutes. To observe the 1, the observation of the trace, should be applied after the development agent, until the size of the trace does not change, about 7-15 minutes, the observation of the development should be in the application of the development agent within 7 to 60 minutes. 2, observe the trace, must be in sufficient natural light or white light. 3, the observation shows the trace, can be used by naked eye or 5- 10 times magnifying glass. 4, can not distinguish the true and false defect traces, should be the part of the second test. Results judgment and recording 1, according to the size of the trace and color to judge the size and severity of the defect. 2. If the ratio of the length and width of the defect display trace is not less than 3, it is called the linear defect trace, and the strip defect will show the linear trace. 3. If the ratio of the length and width of the defect trace is less than 3, it is called circular defect trace. Nearly circular defects such as pores, for example, will show a circular trace. 4, defect display trace, according to the need to record with photography, schematic diagram or peeling agent, etc. 5. Mark the parts where the defects on the inspected surface show traces. The inspection report includes: 1. Code name, name, material, surface state and quantity of the inspected workpiece; 2, the entrusting unit, according to the technical documents and inspection requirements; 3. Model and category of tinted flaw detection agent; 4, detection sensitivity (indicate the type of test block), flaw detection results; 5. Signature of flaw detection personnel and audit personnel; 6. Application date and report date.

Stainless steel casting is not only suitable for a variety of types, all kinds of alloy casting, and the production of casting dimensional accuracy, surface quality is higher than other casting methods, and even other casting methods are difficult to cast complex, high temperature resistance, not easy to process the casting, can be used investment precision casting. So-called investment casting process, simply be with fusible materials (such as wax material or plastic) made meltability model (referred to as "investment pattern or model), on which the coated with several layers of tailor-made refractory coating, after drying and hardening type to form a whole shell, reoccupy steam or hot water from the melt in the shell model, and then put type shells in the sand, dry sand by filling in all round its modelling, Finally, the casting shape is put into the roaster and roasted at high temperature (if high strength shell is used, the demelled shell can be directly roasted without molding). After roasting, molten metal is poured into the casting shape or shell to get the casting. The dimensional accuracy of investment castings is high, generally up to CT4-6(CT10-13 for sand casting and CT5-7 for die casting). Of course, due to the complex technological process of investment casting, there are many factors that affect the dimensional accuracy of castings. Such as shrinkage, deformation of investment casting mould materials, shell in the process of heating and cooling line quantity change, alloy of shrinkage and deformation of the casting during solidification, etc., so ordinary size although higher precision investment castings, but still need to improve the consistency (in medium and high temperature of the wax casting size consistency to improve a lot). When pressing the investment mold, the pressure mold with high surface finish of the cavity is used, so the surface finish of the investment mold is also relatively high. In addition, the shell is made of high temperature resistant special binder and refractory material made up of refractory coating coated on the investment mold, and the surface of the cavity in direct contact with the molten metal has high finish. Therefore, the surface finish of investment castings is higher than that of general castings, generally up to Ra.1.6~3.2μm. The biggest advantage of investment casting is that because of the high dimensional accuracy and surface finish of investment casting, it can reduce the mechanical processing work. Only a little processing allowance can be left for the parts with high requirements. Even some castings can only be left for polishing and polishing, so they can be used without mechanical processing. It can be seen that the use of investment casting method can greatly save machine tools and equipment and processing hours, and greatly save metal raw materials. Another advantage of the investment casting method is that it can cast complex castings of various alloys, especially superalloy castings. For example, the blade of a jet engine, its streamlined profile and cooling cavity can hardly be formed by machining technology. Using investment casting technology can not only achieve mass production, ensure the consistency of casting, but also avoid the stress concentration of residual cutting lines after machining

With the continuous development of society, people's living needs are also getting higher and higher, and the demand for aluminum casting process is also increasing. When we use and use aluminum casting process, do we understand the advantages of aluminum casting produced by aluminum casting? The advantages are as follows: 1, the product quality is good: the casting dimension accuracy is high, generally equivalent to 6~7 grade, its up to 4 grade; Good surface finish, generally equivalent to 5-8 grade: high strength and hardness, the strength is generally higher than sand casting 25-30%, but the elongation is reduced by about 70%; Stable size, good interchangeability; Die - cast aluminum thin - walled complex castings. For example, the current minimum wall thickness of zinc alloy die casting aluminum parts can reach 0.3mm; Aluminum alloy casting up to 0.5mm; The minimum cast aperture is 0.7mm; The minimum pitch is 0.75mm. 2, high production efficiency and high machine productivity, such as domestic JⅢ3 horizontal cold air die casting machine can die casting aluminum 600~700 times in an average of eight hours, small hot chamber die casting machine can die casting aluminum 3000~7000 times in an average of eight hours; Die casting aluminum mold has a long life, a set of die casting aluminum mold, die casting aluminum bell alloy, life can reach hundreds of thousands of times, even millions of times; easy Realize mechanization and automation. 3, excellent economic effect due to the precise size of die-casting aluminum, surface gloss and other advantages. Generally no longer for mechanical processing and direct use, or processing volume is very small, so it not only improves the metal utilization rate, but also reduces a lot of processing equipment and working hours, casting price is cheap; Aluminum can be combined with other metal or non-metal materials. It saves both assembly time and metal. 4, aluminum castings are being used in the process of its advantage in (explanation: can overwhelm the other side of the favorable situation) is quite significant, the use of the product domain, occupies a large part of the auto industry, especially now the auto industry especially pay attention to the light of the properties of aluminum castings can get more extensive application in automobile industry, The density of aluminum castings is actually lighter than that of iron castings and steel castings, and the strength of aluminum castings is relatively large in the process of use. 5. The weight of aluminum casting is relatively light, but its products can bear relatively high weight. In the process of design, the structural weight of the casting can be effectively reduced, so such equipment is widely used in industry, transportation machinery and power machinery. 6, in the chemical industry, the aluminum (Al) castings are widely used in the certain degree, main is to use when making use of the thermal conductivity, aluminum alloy and pure aluminum in the aluminum castings made after can be used in the chemical production of heat exchange device (type: hybrid power machinery and surface type and has good heat conduction performance of the parts. Non-ferrous metal casting accounts for a large share of the use of non-ferrous metal materials (sometimes nearly half), forming a large and complex series of cast alloys. Non-ferrous alloy casting, in the non-ferrous metal alloy, copper alloy, aluminum alloy, magnesium alloy, zinc alloy and so on can be used for casting. 7. The density of aluminum (Al) castings is smaller than that of cast iron and steel, and the specific strength is higher. Non-ferrous metal casting non-ferrous metal smelters often supply metal ingot with certain chemical composition for the subsequent process of preparation of various alloys; Smelters and processing plants are also often separate. Therefore, under the condition of accepting the same load, the selection of aluminum alloy castings can reduce the component of the layout, so in the aviation industry and power machinery and transport machinery production, aluminum castings are widely used. 8. Aluminum castings have outstanding casting functions. Because the melting point is low, it can widely choose metal mold and pressure casting casting methods, in order to improve the content quality of castings, scale accuracy and appearance of smoothness and production power. 9. Because of the large latent heat of condensation on aluminum castings, under the same component conditions, the condensation process of liquid aluminum is continuously much longer than that of cast steel and cast iron, and the discharge fluidity is excellent, which is conducive to the casting of thin wall and disorderly layout of the castings.

There are 10 points you have to note when you are designing the products to make by CNC machining. 1. Thinnest Wall Thickness The wall thickness of the design can`t be too thin. The recommended minimum size is following: Metal:0.8mm Plastic:1.5mm Studies have shown that wall thickness is proportional to the stiffness of the material, therefore lowering the wall thickness would also lower the stiffness of the material hence reducing achievable accuracy as a result of inevitable vibrations during machining. Generally, the sheet metal fabrication is the most suitable manufacturing method for the products with wall thickness less than 6mm. 2. Avoid the design that can`t be CNC machined. Not every feature is machinable. Unnecessary elements would just make designs challenging to produce, similar to thin walls. When designing for CNC machining, having knowledge of the machine`s capabilities is frequently advantageous because it will assist you create design that the machine can produce. Curved holes are an illustration of a feature that is impossible to process and cannot be made by CNC mills, lathes, or drills. However, electrical discharge machining (EDM) may be employed if this characteristic is required for your design, along with additional features that are difficult to be machined. 3. Tolerance requipment Tolerances should not be used excessively. Designers are expected to allow for dimension tolerances where necessary. However, it should be noted that excessive tolerancing would only increase machining time and cost. Because different CNC machines have different tolerance standards, if your dimensions do not have tolerancing, the machine will use its standard tolerance for such dimensions. Tight tolerances should be specified only when absolutely necessary to save time and money. Maintaining homogeneous tolerancing is also important because it reduces machining time. Tianhui tolerance standard is based on [ISO 2768-mK". 4. Don`t design extraneous aesthetic elements. Some features, as stated in the aforementioned ways to improve CAD designs, are only cosmetic and cannot be machined efficiently. Before removing parts for cosmetic reasons, consider the amount of material to be removed and the process to be used. As a designer, you should always ask yourself, [What process would this feature require?" or [Is it a 5-axis or a 3-axis machining process?" You can improve your design by focusing on the accuracy of necessary features rather than aesthetics, because aesthetics can be achieved through post-machining processes such as electro-polishing. 5. Create cavities that have precise depth-to-width ratios. When designing cavities, you can improve your design by considering the depth to width ratio. Too deep cavities would result in the tool hanging, deflection, chip evacuation difficulty, and tool fracture. Cavities should have a maximum depth of four times the cavity`s breadth and should not be higher than six times the tool`s diameter. For example, the cavity that is 15 mm wide shouldn`t be any deeper than 60 mm. 6.When designing internal edges, add radii. Considering the form of the milling tool, designing interior sharp edges is difficult. It is crucial to include radii to interior edges in your design because the majority of cutting tools are cylindrical and cannot machining sharp internal edges. Internal edges that don`t put the tool under excessive stress must be designed in order to prevent tool wear and tear. A decent general rule of thumb is to increase the radius by 130 percent of the milling tool radius in order to achieve this. If the radius of your milling tool is 5 mm, it is advised that you increase all of your internal angles by 6.5 mm. The tool would experience less strain and cut more quickly with the added radius. 7. Thread Length Thread minimum size is M2 ; M6 or larger recommended The internal thread is cut with a tap, and the external thread is cut with a tool. Taps and tools can be used to cut threads to M2. CNC thread tools are common and preferred by machinists because they limit the risk of tap breakage. CNC thread tools can be used to cut threads to M6. 8. Avoid designing features that are too small. Because the minimum tool diameter on most CNC machines is 2.5mm, any feature smaller than 2.5mm would be difficult to machine. Too small features would necessitate the use of a special tool, increasing machine costs and time. As a result, small features should be avoided unless absolutely necessary. 9. Standard-sized holes The drill diameter recommended standard size: any diameter greater than 1 mm will work. Use a drill or end milling cutter to machine the hole. The dimensions of drill bits are standardized (metric and imperial units). Reamers and boring tools are used for finishing holes that require tight tolerances. For smaller than ⌀20 mm, standard diameter is recommended. 10. Text and lettering Recommended font size is 20 (or larger) with 5mm lettering. Embossed text is preferred for engraved text because removed material is less. The sans-serif font (such as Arial or Verdana) that is at least 20px in size is recommended. Many CNC machines have pre-programmed routines for these fonts. The above 10 points are very import for How to Design Parts for CNC Machining.

Tianhui Machine is a professional precision machining factory in China and will tell how to produce handwheels on this article. Our headquarter factory is at Ningbo City, Zhejiang Province. And we have a branch factory at Chizhou City, Anhui Province. So that we can have enough production capacity for all our new and old customers. We produce various metal cnc machining parts, machining from casting blanks, forging blanks, raw material, tube, etc. The main material is stainless steel, carbon steel, alloy steel, aluminum, cast iron. All according to customer`s drawings. Verified with ISO/TS16949 certification. Now, let me introduce how do we produce handwheels. Handwheel is a very simple product, the main process is by sand casting and cnc machining. Firstly, we produce the casting blanks by sand casting process. Secondly, after casting of the handwheels finished, we manufacture the main assemble dimensions by cnc machining. Thirdly, we send the handwheels to do electro plating after cnc machining finished. Then do final inspection and package. We protect products with good package, so that goods will not be damaged. Welcome to contact with us for more information.

There are 7 distinctive characteristics of sand casting you have to know if you are working in machinery industry. The strength of chemically hardened sand mold is much higher than that of clay sand mold, and after being made into sand mold, it is hardened to a relatively high strength and then demolded, and no repairing is required. Therefore, the mold can more accurately reflect the size and contour shape of the pattern, and it is not easy to deform in the subsequent process. The obtained casting has high dimensional accuracy. Because the viscosity of the binder and hardener used is not high, it is easy to mix with the sand particles. The sand mixing equipment is light in structure, low in power and high in productivity, and the sand processing part can be simplified. The mixed molding sand has good fluidity before hardening, and the molding sand is easy to be pounded during molding, so a large and complicated molding machine is not required. When modeling with chemically hardened sand, pattern materials such as wood, plastic and metal can be selected according to production requirements. The content of binder in chemically hardened sand is much lower than that of clay sand, and there is no powdery auxiliary material in it. If the original sand with the same particle size is used, the gap between sand particles is much larger than that of clay sand. In order to avoid metal infiltration between the sand grains during casting, the surface of the sand mold or core should be coated with a good quality coating. The chemical hardening sand with water glass as the binder has low cost and no odor in the working environment during use. But this kind of casting mold is not easy to disintegrate after pouring metal; the used old sand cannot be directly recycled and must be regenerated, and the regeneration of sodium silicate sand is more difficult. The cost of chemically hardened sand with resin as a binder is higher, but the casting is easy to separate from the molding sand after pouring, the workload of casting cleaning is reduced, and most of the used sand can be recycled and reused.
