What are the options for computer gong processing based on the principle of fine benchmark selection? What are the options for computer gong processing based on the principle of fine benchmark selection? The following editor will explain to you: (1) The φ32H7 hole restricts four degrees of freedom, and the bottom surface restricts one degree of freedom. This solution has a reference misalignment error for the size of 4±0.1mm, and the positioning pin is slender and has poor rigidity, so it is not it is good. (2) The bottom surface restricts three degrees of freedom, and the φ32H7 hole restricts two degrees of freedom. This solution can be realized by setting the workpiece on a long diamond pin. The three design requirements are all referenced. The high-speed computer gong processing only φ32H7 hole The parallelism error of the bottom surface will affect the parallelism of the two holes in the vertical plane, which should be restricted when boring φ32H7 holes. (3) The bottom surface restricts three degrees of freedom, and the K surface restricts two degrees of freedom. This program uses the principle of unified reference for machining two holes. The fixture is relatively simple. The design dimension 4±0.1mm standard coincides; the process standard of the dimension 51±0.1mm is the center line of hole φ32H7.

Because the acceptance of the CNC machining center directly affects the factory’s equipment being put into use, the general factory acceptance standard is to directly perform the workpiece processing test. In fact, after the workpiece processing test, it can basically be determined that the key parts of the processing center meet the standards. There is no problem under normal use. What about the spindle performance inspection of the cnc machining center? Choose low, medium and high speeds. The main shaft performs 5 consecutive forward and reverse rotation starts, and then stops the operation to verify the flexibility and reliability of its action. At the same time, check whether the power display on the load meter meets the requirements. Manual data input can be used to gradually increase the spindle speed from low speed to allowable speed. Check whether the speed is normal, the general allowable error should not exceed ±10%. While checking the spindle speed. Observe whether the noise, vibration, and temperature rise of the spindle are normal. The temperature rise of the spindle after 2 hours of high-speed operation is 15"C. 3. In order to check the flexibility and reliability of the spindle movement, the spindle can be stopped exactly and operated continuously for more than 5 times.

Aluminum alloy is a widely used material in the industrial industry. It plays a great role in aviation, aerospace, automobiles, and machinery. The density of aluminum alloy is low, but the strength is relatively high, which is close to or exceeds that of high-quality steel, and has good plasticity. It can be processed into various profiles with excellent electrical conductivity, thermal conductivity and corrosion resistance. It is widely used in industry and its usage is second only to steel. The production range of aluminum alloy is quite huge, allowing you to meet the needs of any industry. Issues that should be paid attention to in the aluminum alloy CNC machining process: (1) Determine the machining content of the CNC machining center, determine the installation base surface, machining base surface, machining allowance, etc. of the workpiece, and arrange for the purpose of giving full play to the efficiency of the CNC machining center Processing procedure. (2) For complex parts, due to thermal deformation during processing, internal stress after quenching, deformation of parts after being clamped, etc., it is difficult to complete all processes after one clamping.
