Flourish Legend Teaches You Four Things to Pay Attention to in CNC Processing

If a machine is kept in the dark and humid for a long time, the sky is full of dust, oil and various other chemical liquids are corroded, and the production personnel move the machine without authorization, what problems will arise, and what problems will arise. It goes without saying that there are so many problems, not only the machining accuracy and performance of the machine will decrease, the loss will increase greatly, and the replacement frequency of parts will soar, which will increase a lot of time and cost, and our precision CNC machining machines will be easily scrapped. So today I will summarize the items that have a high probability of affecting CNC processing, and you can refer to avoidance to reduce loss.

Replacement Frequency of Parts

1. Overcut inspection of CNC machining precautions:

Over-cutting is a frequent problem, and special attention should be paid to it. The most important inspection method is to simulate the tool path once and repeat the inspection in the top view and side view. The tool path without inspection is not allowed to be machined. When the shape is milled, if the lower tool position is selecte to be small, it will also overcut, which can be avoided by changing the lower tool point.

2. Mold tolerance of CNC machining precautions:

The accuracy of CNC lathe processing parts is very strict. Only when the required accuracy can be used can it be used. To judge this accuracy, it mainly depends on its ability to control the size. If this accuracy Parts are acceptable within the specified range within which the tolerance can fluctuate, and rejected if they exceed the tolerance.

3. Clamping tool for CNC machining precautions:

Before the cutter head is installed on the machine, its taper matching position should be wiped clean with a cleaning cloth. For the tool length, use the tool tip tool setting method (in special cases, use the tool setting method in the tool), and carefully check the instructions in the program sheet when setting the tool. When the program is interrupted or the tool must be re-set, attention should be paid to whether the depth can be connected to the front. Generally, it can be adjusted by 0.1mm first, and then adjusted according to the situation. For the rotary retractable cutter head, if water-soluble cutting fluid is used, it should be maintained in lubricating oil for several hours every half month.

4. Arrangement of the processing sequence of CNC processing precautions:

When arranging the processing sequence, the basic principles must be followed, including "face first, then hole", "rough first, then fine", etc. In addition to these basic principles, you should also: process according to the centralized process of the tool, and avoid repeated repetition of the same tool Use to reduce the number of tool changes and time. For the hole system with high coaxiality requirements, after one positioning, all the machining of the hole system should be completed, and then the hole system at other coordinate positions should be processed, so as to eliminate the error caused by repeated positioning and improve the hole system. coaxiality. Choose to determine the tool point and tool change point. Once determined, it is not suitable to replace.

These are the problems that customized CNC machining should pay attention to, and they are also worthy of consideration. That's all for today's flourish legend sharing, please share in the next issue.
