Generally, the accuracy of  Precision Machining  is affected by many factors, such as casting structure, material, mold making, shell making, roasting and pouring. Any part or unreasonable operation will change the shrinkage of castings, resulting in deviation of casting dimensional accuracy with requirements. 1. The impact of casting structure: casting wall is thick, its shrinkage rate is big, on the contrary, the shrinkage is small. 2. The impact of casting materials: the higher the carbon content in material, the smaller line shrinkage rate. 3. Mold on the shrinkage of casting, shell materials and shell calcination will impact accuracy of  Precision Castings . 4. The impact of casting temperature: the higher the pouring temperature, the greater the shrinkage, otherwise, the shrinkage is small, so the pouring temperature should be appropriate.

Automatic Lathe is a high performance, high precision, low noise pass-knife automatic lathe, through the cam to control the processing of  Automatic Lathe Machining . It suitable for cooper, aluminum, iron, plastic and other  Precision Machined Parts  processing. 1. Before working according to regulations lubricate the machine, check whether the handle in place or not, and open the trial run for five minutes to confirm that all normal before operation. 2. Chuck should be fastness, wrench can not stay in the chuck when starting up. 3. Workpiece and tool clamping to be solid, cutter arbor should not be stretched too long. Turn knife and stop the machine to prevent tool and chuck collision, or cut hand. 4. When workpiece is running, the operator can not stand on the workpiece, the body do not rely on lathes, feet do not step oil pan. 5. High speed cutting, chip breakers and retaining screen should be used. 6. Prohibit high speed anti-braking, and parking smooth....

CNC Turning  is a high precision, high efficiency, automated machine tools, it is the largest use in domestic, covering the widest range of a CNC machine tools. CNC turning has a wide range of processing performance, can be processed linear cylinder, diagonal cylinder, arc and various threads. Selecting suitable CNC turning should keep to the following principles: 1. Pre-preparation: determine the typical parts of process requirements, processing workpiece volume, proposed  CNC Lathe . Process requirements are mainly parts of structural size, processing range and accuracy requirements. 2. Machine tool accessories and tool selection: machine tools accessories, parts and supply capacity, tools is important for CNC lathes. Select the machine, need to consider the matching of tools and accessories carefully. 3. Focus on the control system identity: choose the control system from the same manufacturer is convenient to the maintenance. 4. According to the performance-cost r...

CNC Milling  is multitudinousness, there are some basic operating matters to pay attention: 1. When you into the workshop to practice, put on the overalls, big cuffs to be tight, female wear helmets and braids into the cap. Do not wear sandals, slippers, high heels. Note: gloves are not allowed to operate the machine. 2. Do not move or damage the warning signs installed on the machine. 3. Do not place obstacles around the machine, keep the work space large enough. 4. Work which need two or more people together to complete, should pay attention to mutual coherence. 5. Do not allow the use of compressed air cleaning machine tools, electrical cabinets and NC unit. 6. We should practice in the specified machine and computer. Without permission, other machine tools equipment, tools or electrical switches shall not touch.

Micro Machining  is machining small workpieces. Micro machining often used in medical devices field and electronics field, it generally performed in a special shop dedicated to small parts or  Precision Machining . 1. When processing the small size, due to its small size, the accuracy must be represent with the absolute value of size, that is, the size which take out a piece of material, then introduce the concept of processing unit size. 2. The microscopic mechanism. The biggest difference between general processing and micro processing is the size of the chip. The metal material is generally composed of fine grains, the grain diameter is several microns to hundreds of microns. General process can ignore the size of grain, their mechanism is different. 3. Micro machine take separating or combining atoms, molecules as processing objects, electron beam, mechanic beam, particle beam as processing base, using deposition, etching, sputtering, evaporation and other means for...

CNC Turning  is a high precision and high efficiency automated machine tools. Equipped with multi-station turret or power turret, it has a wide range of processing technology performance and can processed various complex parts and kinds of compensation functions. CNC lathe plays a good economic results in the mass production of complex spare parts. In order to ensure the work accuracy of lathe bed CNC lathe and prolong its service life, it is necessary to carry out reasonable maintenance work timely for the CNC lathe. Lathe maintenance is good or bad, affect the workpiece processing quality and production efficiency directly. After the CNC lathe running 500h later, it need A class maintenance. Slant bed CNC lathe maintenance work five priority to operators, maintenance workers to cooperate. When Maintenance, you must cut off the power firstly, and then maintain it according to the contents and requirements.

CNC Milling  except has the characteristics of ordinary milling machine, there are following features: 1. Strong adaptability and good flexibility for parts processing, it can be processed complex shapes or difficult to control size of the parts, like mold parts, shell parts. 2. CNC milling can process mathematical model described in the complex curve parts and three-dimensional surface parts. 3. It can be processed parts that once fixture positioning, need for multi-channel processing. 4. High precision processing, stable and reliable processing quality. Numerical control device pulse equivalent is 0.001mm, high precision CNC system can up to 0.1μm, in addition, CNC machining can avoid the operator’s operational errors. 5. High degree of automation reduce the operator’s labor intensity. This is conducive to production management automation. 6. High production efficiency, CNC milling do not need special fixtures or other special process equipment generally, only need t...

Injection Molding  is the most commonly manufacturing process for plastic parts, it manufactured various products, which vary greatly in their complexity and size.  Plastic Injection Molding  process need an injection molding machine, raw plastic materials and a mold. The plastic is melted in the injection molding machine, then injected into the plastic mold, it cools and solidifies in to the final part in there. Injection molding used for thin-walled plastic parts for various applications, the most common is plastic shell, which is a think-walled enclosure, on the interior often require many bosses and ribs. These shells are widely used in various products including consumer electronics, household appliances, automotive dashboards, etc. Injection molding is also used to produce everyday commodity, like tooth brush, small type plastic toys. Many Medical Device Components are also manufactured by injection molding. Quick-turn injection molding use standard parts product...
