CNC (Numerical Control Machine Tool) is the abbreviation of Computer numerical control, which is an automatic machine tool equipped with a program control system. The control system can logically process the program with control codes or other symbolic instructions, and decode it, so as to make the machine tool move and process the parts. component: The host machine is the main body of the CNC machine tool, including the machine body, column, spindle, feed mechanism and other mechanical parts. It is a mechanical part used to complete various cutting processes. The numerical control device is the core of the numerical control machine tool, including hardware (printed circuit board, CRT display, key box, paper tape reader, etc.) and corresponding software, used to input digital part programs, and complete the storage of input information and data Transformation, interpolation calculation and realization of various control functions. The driving device, which is the driving part of the CNC machine tool actuator, includes the spindle drive unit, the feed unit, the spindle motor, and the feed motor. Under the control of the numerical control device, it realizes the spindle and feed drive through the electric or electro-hydraulic servo system. When several feeds are linked, the processing of positioning, straight line, plane curve and space curve can be completed. Auxiliary devices, some necessary supporting parts of index-controlled machine tools, are used to ensure the operation of CNC machine tools, such as cooling, chip removal, lubrication, lighting, monitoring, etc. It includes hydraulic and pneumatic devices, chip removal devices, exchange tables, CNC turntables and CNC indexing heads, as well as cutting tools and monitoring and testing devices. Programming and other ancillary equipment can be used to program and store parts outside the machine. Operation and maintenance Design engineers are thankless jobs. They never stop spending energy to constrain tolerances and improve accuracy to fight failures and downtime. They have improved the design accuracy to about 1 micron year after year. They are perfectionists. But when the tools are not properly balanced, their thorough and careful attention to detail produces waste. Machining parts with unbalanced tools is similar to shooting your own feet. The tool will wear out normally after performing the design task. However, the tool designed to perform that task is assumed to be well-balanced. If you use an unbalanced tool for this job, you are introducing new levels of wear, not only for the tool and spindle but also for the parts to be executed. Imbalance can have several effects: it can introduce additional vibrations to the spindle and its components, it will wear the tool irregularly, it can reduce the life of the tool and reduce the quality of the finished product. Appropriate accuracy = better balance In addition to the correct maintenance and handling of high-quality tool holders, it is importan...

What is Gravity Casting: Gravity casting refers to the process of injecting molten metal into a mold under the action of the earth's gravity, also known as casting. The generalized gravity casting includes sand casting, metal casting, investment casting, lost foam casting, mud casting, etc. The narrow gravity casting refers specifically to metal casting. The molten metal is generally poured into the gate manually, and the product is obtained by filling the cavity, exhausting, cooling, and opening the mold by its own weight. The process flow is: smelting, casting filling, exhaust, cooling, mold opening, heat treatment, and metal processing. Die casting introduction: Pressure casting is divided into two types: high pressure casting and low pressure casting. High pressure casting is a casting method in which molten alloy liquid is poured into a press chamber, the cavity of a steel mold is filled at high speed, and the alloy liquid is solidified under pressure to form a casting. The main characteristics of high pressure die casting that distinguish it from other casting methods are high pressure and high speed. ①The molten metal fills the cavity under pressure, and crystallizes and solidifies under higher pressure, the common pressure is 15-100MPa. ②The molten metal fills the cavity at a high speed, usually 10-50 m/s, and some can exceed 80 m/s, (the linear velocity of the cavity through the inner gate-the inner gate speed), so the molten metal The filling time is extremely short, and the cavity can be filled within about 0.01-0.2 seconds (depending on the size of the casting). The process of low-pressure casting is as follows: in a sealed crucible (or sealed tank), dry compressed air is introduced, and under the action of gas pressure, the molten metal enters the sprue along the riser pipe and rises smoothly through the inner runner. Enter the cavity and maintain the gas pressure on the liquid surface in the crucible. Until the casting is completely solidified. Then the gas pressure on the liquid surface is released, and the unsolidified molten metal in the riser pipe flows back to the crucible. Reopen the mold and take out the casting. It can also be said that low-pressure casting is a compromise between high-pressure casting and gravity casting. - https://www.desuautomatic.com/

The water supply system required for equipment testing consists of a hot water system and a cold water system, both of which usehigh-performance water pumps, andlt adopts fully automatic frequency conversion control, only need to manually set the water pressure value on the man-machine interface and turn on the water pump switch. Among them, the refrigeration system has two functions of cooling and auxiliary heating. When the temperature is high, the refrigeration is turned on, and vice versa. , Turn on auxiliary heat (auxiliary heat when the water temperature is low in winter). 1. The heating system provides the hot water temperature required for the test, and the refrigeration system provides the cold water temperature required for the test. The cold and hot water temperatures can be easily set and are automatically controlled by a thermocouple and PLC. The temperature control accuracy can reach ±2°C; 2. The cold water pump water supply system provides the cold water pressure required for the test, and the hot water pump water supply system provides the hot water pressure required for the test. Both the cold and hot water pressures are controlled by constant pressure frequency conversion. The closed-loop control principle is adopted and 0.5 is installed in the pressure test pipeline. The high-precision pressure sensor detects the pipeline pressure value in real time, and converts it into a 4-20mA signal and transmits it to the PLC signal acquisition module. The PLC outputs the corresponding signal to the frequency conversion according to the preset program and the pressure value set by the touch screen. Through the conversion of the output frequency of the inverter, the control of the constant pressure value of the output water pressure of the pressure water pump is realized: 3. The cold and hot supply and return water valve system is controlled by the PLC system. Through the touch screen parameter setting and the PLC built-in program, the alternate supply function of cold and hot water to the test sample can be realized, and the cold and hot water can be recovered separately. The circulating water can be reused after reheating or cooling to achieve the purpose of water saving and energy saving; 4. Drive device: The pressure used in the life test is automatically controlled by an air cylinder, and the drive head is equipped with soft materials to ensure that the pressing surface of the test sample is in flexible contact, and the effect of protecting the product is obtained; 5. Tooling and fixture: use the standard water tank required by JC987-2005: 400X175X300 (mm), the water tank has a hole inside, and the size of the hole can be changed to facilitate the realization of the joint, and obtain products of different specifications within the requirements of the test standard; 6. The electronic control system adopts PLC and touch screen, which can set the total test times, the test ratio of large/small gears, the pressing hold time, the stop water...

The difference between sand blasting machine and shot blasting 1. The working principle is different: Shot blasting uses a high-speed rotating impeller to throw small steel shots or small iron shots out to hit the surface of the part at high speed, so the oxide layer on the surface of the part can be removed. Sandblasting is a method of using compressed air to blow out the quartz sand at high speed to clean the surface of the part. 2.Different materials used The steel shots and iron shots used in shot blasting are not actually shots. To be precise, they are small steel wires or small steel rods. They only look like shots after a period of use. The so-called sandblasted sand is just river sand, which is no different from that used for construction, except that the sandblasted sand is screened, contains less mud, and has a particle size specification. Of course, some industries are also different. For example, real steel shot is used for shot blasting in the shipbuilding industry, and metal ore (not river sand-quartz sand) is used for sand blasting. 3. Different functions: The main function of sandblasting is to remove rust and scale on the surface, such as parts after heat treatment. Shot blasting has many functions. It not only removes rust and surface oxides, but also improves surface roughness, removes machining burrs of parts, eliminates internal stress of parts, reduces deformation of parts after heat treatment, and improves surface wear resistance of parts. Pressure capacity, etc. 4. Different materials used: The steel shots and iron shots used in shot blasting are not actually shots. To be precise, they are small steel wires or small steel rods.
