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/
