In industrial production, precision parts processing is the most commonly used means and method, and in this area of technology, the first thing to consider is the quality and structure of the parts themselves. No matter what processing method is used, it will not help if inferior parts are selected. Therefore, the processing quality of precision parts is an important part of precision parts processing. When it comes to components, it is an important product in many mechanical equipment. Components are the basic elements that make up a machine. Machinery usually includes one or more transmissions (eg, motors, internal combustion engines, steam engines) for receiving external energy.
Complete the execution part of the mechanical production function (such as the tool in the machine tool), transmit the motion and power of the prime mover to the transmission part of the execution part (such as the gear and screw transmission mechanism in the machine tool), and ensure the detection of the coordinated work of various parts in the machine And the control system (such as the numerical control system in the machine tool) (that is, the machine is composed of the driving part, the transmission part, the execution part, and the measurement and control part). Then disassemble the machine to get various parts.
Precision parts are the basic elements of a machine, which can be classified into two categories: one is the parts (such as gears, shafts, etc.) Parts (such as bolts, propellers, etc.) that are only used in the machine are called special parts; in addition, parts composed of certain parts that work together can also be combined, called parts or assemblies. (e.g. coupling, reducer, etc.)
It is of course very important to master the knowledge of precision parts processing, because if one of the operations goes wrong, it will definitely affect the quality of the product, so in some details, the above problems are very important, let's understand Knowledge of precision parts processing.
1. Ensure stable and reliable processing performance of cutting tools
When machining on a CNC machine tool, the cutting performance and life of the tool should be stable and reliable, and the tool should be changed regularly or the life of the tool should be managed by the control system. The same batch of CNC tools should not have a large difference in cutting performance and life. , Avoid frequent shutdowns to change tools or 2. A large number of processed workpieces are scrapped.
Guaranteed longer cutting tool life
The blade should have a high service life, and the coated blade with good performance and wear resistance should be selected and the cutting amount should be reasonably selected.
3. Avoid tool loss
To ensure the reliability of chip breaking, chip rolling and chip removal, a chaotic chip breaking system will bring great harm to automated production, causing the blade to fall off and causing various degrees of wear and tear.
4. Ensure the transition of the tool state
Ensure quick gear changes, blade changes, and automatic tool changes.
5. Adjust the knife position scientifically and reasonably
It can quickly and accurately adjust the size of the tool processing parts, the initial positioning point of the tool, etc.
