With the rapid development of high-tech and independent innovation, the application of CNC machining is becoming increasingly common. So, what are the common CNC machining methods?
1. Flat face parts: When selecting the technical circuit, two key criteria should be considered: machining precision and machining efficiency, for commonly used geometric shapes operated by computer gongs and CNC lathes (such as computer gongs and planers).
2. Plan outline parts: When using electronic computers to process plan outline parts, attention should be paid to: inner and outer drilling direction manipulation: tangential drilling, leaving indentations on the surface of the workpiece; Level the cut and level the surface of the workpiece. One time approximation method selection: When using a computer-controlled lathe with parallel line and arc-shaped tool radius compensation to process irregular curve contours, as long as parallel lines or arc-shaped fine lines are used to approximate the machining contour (this deviation is called deviation one time approximation), the workpiece error should be within the standard range and the number of pieces should be small.
3. Three dimensional contour parts; When processing three-dimensional contour parts, the following aspects should be considered: taking into account the strength and surface quality of the workpiece: after the workpiece is subjected to stress, the compressive strength is low, and the surface quality is best. Considering the tool radius compensation effect of CNC lathes: when machining the distorted surface of flat beams, if the CNC lathe is three-axis linked, a high-efficiency ball cage turning tool should be used; If the CNC lathe is 4-axis linked, the most efficient inner hole cutting can be applied.
4. Rotary wheel line parts: The machining of rotating parts is usually carried out using CNC lathes or CNC grinders on computers. What should be noted in this process? Considering the high efficiency of machining: When machining on the lathe edge, the machining capacity is usually relatively large, and an effective mechanism for rough machining should be established to improve machining efficiency. In specific program writing, it is generally not recommended to use the loop system command (otherwise there will be too many tool connections under the working tool rate). A stronger approach is to use precision machining to remove raw materials as early as possible and then proceed with boring. Considering the compressive strength of the sharp blade: Low strength CNC blades are commonly used for machining small grooves near the computer lathe bed. The above four methods are commonly used by precision parts processing companies for CNC machining. Which one is better? This is also based on the necessity of enterprises to pay attention to relevant issues when processing different parts.
