What does the acceptance of precision CNC machining parts include? Specifically, including acceptance requirements and acceptance procedures, etc., today we will introduce the content of the two parts of acceptance requirements and acceptance procedures, as follows.
CNC machining is a kind of lathe developed on the basis of ordinary lathes. Compared with ordinary lathes, it is widely used in mechanical parts due to its strong adaptability, high CNC machining accuracy, high CNC machining efficiency and reduced labor intensity. in production.
CNC turning accuracy refers to the degree of conformity between the actual geometric parameters of the workpiece surface after machining and the expected geometric parameters, and the higher the degree of conformity, the higher the CNC machining accuracy.
In order to avoid the above-mentioned collision, the operator should give full play to the functions of the five senses when operating the machine tool. Observe the machine for abnormal movement, sparks, noise, rattling, vibration, and burnt smell. If any abnormal situation is found, the program should be stopped immediately, and the machine tool can continue to work after the machine tool problem is solved.
When we use CNC machining, we often find that the outer circle of CNC machining parts has a taper phenomenon, which makes the diameters at both ends of the workpiece size inconsistent, which exceeds the tolerance range. So, what is the reason for the taper of the outer circle of CNC machined parts? How can we solve the problem of the taper of the outer circle of CNC machined parts?
Turning, milling, planing, grinding, drilling, boring, the highest precision of these machines and the tolerance levels achievable by various CNC machining methods are here.
CNC machining can be divided into two types according to the machining accuracy, namely rough machining and finishing. Usually, rough machining is performed first, and then finishing is performed, which can effectively improve the machining accuracy of the workpiece.
What to do if there are too many burrs when milling aluminum parts with CNC machining? Burrs will not only reduce the machining accuracy of CNC machined aluminum parts, thereby affecting the performance of the parts, but also increase the cost of CNC machining.
