CNC Precision Metal Machining Precautions and Features

　　Things to watch out for CNC Precision Metal Machining:

　　Before each program is processed, it is necessary to strictly confirm whether the tool is consistent with the program.

　　2. When installing the knife, confirm the length of the tool and whether the selected cutter head is suitable.

　　3. Do not open the door during the operation of the machine to avoid flying the knife or flying the workpiece.

　　4. If the knife is found during the machining process, the operator must stop immediately, such as pressing the “Emergency Stop” button or the “Reset Button” button or turning the “Feed Rate” to zero.

　　5. It is necessary to keep the same area in the same workpiece in the same workpiece to ensure the accuracy of CNC machining center operation rules when the tool is connected.

　　6. If CNC Precision Metal Machining Supplier finds too much machining allowance during the machining process, it must use the “single-section” or “pause” to clear the X, Y and Z values and then manually mill it and then shake it back. Zero" lets it run on its own.

　　7. During operation, the operator must not leave the machine or check the operation status of the machine regularly. If you need to leave in the middle, you must specify the relevant personnel to check.

　　8. Before the light knife is sprayed, the aluminum slag in the machine tool should be cleaned to prevent the aluminum slag from sucking oil.

　　9. In the roughing procedure, use an air blowing as much as possible, and in the light knife program, spray oil.

　　10. After the workpiece is off the machine, it is necessary to clean the deburring in time.

　　11. At the time of leaving work, the operator must make a timely and accurate handover to ensure that the subsequent processing can proceed normally.

　　12. Before shutting down, ensure that the magazine is in the original position, and the XYZ axis stops at the center position, and then turn off the power and main power on the machine operation panel.

　　13. When you encounter a thunderstorm, you must immediately turn off the power and stop working.

　　The ultra-precision part processing method is characterized by extremely fine control of the amount of surface material removed or added. However, in order to obtain the precision of ultra-precision parts processing, it still relies on sophisticated processing equipment and accurate restraint system, and uses ultra-precision mask as an intermediary. For example, the plate making of a very large scale integrated circuit is exposed to a photoresist (see photolithography) on the mask by an electron beam, so that the atoms of the photoresist is directly polymerized (or decomposed) under electron impact, and then The polymerized or unpolymerized portion is dissolved with a developer to form a mask. Electron beam exposure plate making requires ultra-precision processing equipment with a table positioning accuracy of ±0.01 μm.

　　Ultra-precision part cutting

　　There are mainly ultra-precision turning, mirror grinding and grinding. Micro-turning is carried out on a super-precision lathe with a fine-polished single-crystal diamond turning tool. The cutting thickness is only about 1 micrometer. It is often used for the processing of spherical, aspherical and flat mirrors of non-ferrous materials with high precision and high appearance. Components. For example, an aspherical mirror with a diameter of 800 mm for processing a nuclear fusion device has a maximum precision of 0.1 μm and an appearance roughness of Rz 0.05 μm.

　　Ultra-precision parts special processing

　　Ultra-precision parts processing accuracy is nanometer, and even when the atomic unit (atomic lattice distance is 0.1-0.2 nm) is targeted, the ultra-precision part cutting method can not be adapted, and it is necessary to use special precision parts processing method, namely applied chemistry. Energy, electrochemical energy, thermal energy or electrical energy, such that the energy exceeds the joint energy between the atoms, thereby removing the adhesion, joint or lattice deformation between some of the external parts of the workpiece to achieve the purpose of ultra-precision machining. Among these processes are mechanochemical polishing, ion sputtering, and ion implantation, electron beam exposure, laser beam processing, metal evaporation, and molecular beam epitaxy.
