CNC parts processing needs to pay attention to three major problems

2023-07-19

CNC Machining is a very convenient and effective manufacturing technology, which uses computer numerical control (CNC) technology to control machines and tools that process various materials and items. What problems do you need to pay attention to in parts processing?

First, spare parts CNC machining CNC tool selection:

The CNC machining quality of spare parts of product parts depends to a large extent on the control of CNC tool quality. According to the methods of acoustic material monitoring, milling time control, stop inspection during milling, surface layer analysis of product parts, etc., it can distinguish all normal damage conditions and abnormal damage conditions of CNC tools in the whole process of automatic milling. The milling cutter should be solved immediately according to the production and processing regulations to prevent production and processing quality problems due to the inability of CNC tools to be properly handled.

Second, CNC spare parts processing process:

When monitoring roughing, the main consideration is the rapid removal of excess capacity from the surface layer of the product. In automatic production processing, CNC tools automatically carry out milling production according to the predetermined milling motion path according to the set feed amount. At this time, the actual operation staff should pay attention to observe the change of milling load in the automatic production and processing of the entire spare parts processing process, and adjust the feed according to the bearing capacity of the CNC tool to make full use of the comparative efficiency of the CNC machine tool.

(1) After the CNC machining center is powered on, it is necessary to check whether the switch buttons and indicator lights are normal, and if there is an abnormality, it should be shut down immediately and reported to the maintenance personnel.

(2) Before formal processing, the coordinates of the machining center should be returned to zero, and the machine should be idle for more than 15 seconds before it can be officially operated.

(3) In order to simplify positioning and installation, CNC machining centers have relative processing origins in no positioning surface, and have accurate coordinate dimensions.

(4) During installation, ensure that the stroke of the machining workpiece is within the stroke range of the spindle.

(5) When installing the workpiece, ensure that the workpiece is installed tightly, but also pay attention not to be too tight and cause the loss of positioning accuracy.

Third, CNC parts milling sound monitoring:

Usually at the beginning of automatic milling production processing, the sound of CNC tool milling product parts is relatively stable, continuous, and light-paced, and the movement of CNC machine tools is relatively stable. In the whole process of production and processing, due to the hard point of the product parts, the destruction of CNC tools, CNC tool clamping, etc., resulting in unstable production and processing, the expression is the transformation of milling sound, the impact sound between CNC tools and product parts, and the vibration of CNC machine tools. During this time, the feed and milling standards should be adjusted immediately, and when the adjustment effect is not obvious, the CNC machine tool should be interrupted to check the condition of the CNC tool and the product part.
