1. Common problems in CNC machining

CNC machining is a high-precision, high-efficiency machining method, but in practical applications, some problems will also be encountered, such as:

（1）Too fast tool wear: Tool wear is a common problem in CNC machining, especially when machining hard materials. Too fast tool wear will lead to problems such as reduced processing quality, slowed processing speed, and shortened tool life.

（2）Insufficient machining accuracy: The accuracy of CNC machining is usually very high, but in some cases, the machining accuracy may not meet the requirements, such as vibration of the machine tool during machining, tool wear, poor workpiece fixation, etc. may cause insufficient machining accuracy.

（3）Poor machining surface quality: CNC machining surface quality is usually very good, but in some cases, the surface quality may be poor, such as vibration of the machine tool during machining, tool wear, improper setting of machining parameters, etc. good.

（4）Low processing efficiency: The efficiency of CNC machining is usually very high, but in some cases, the processing efficiency may be low, such as excessive tool wear, poor workpiece fixation, improper processing parameter settings and other reasons may lead to low processing efficiency.

2. Second, the solution to the problem in CNC machining

Solutions for excessive tool wear:

(1) Select suitable tool materials and coatings to improve the wear resistance of the tool.

(2) Control the cutting speed and feed speed during processing to reduce the influence of cutting force and heat on the tool.

(3) Keep the cutting fluid clean and sufficient during processing to reduce the influence of cutting heat on the tool.

The solution to the lack of machining accuracy:

(1) Adjust the machining parameters of the machine tool, such as cutting speed, feed speed, cutting depth, etc., to improve machining accuracy.

(2) Improve the fixing method of the workpiece and reduce the impact of machine tool vibration on machining accuracy.

(3) Choose high-precision tools and fixtures to reduce machining errors.

Solutions to poor surface quality:

(1) Adjust the machining parameters of the machine tool, such as cutting speed, feed speed, cutting depth, etc., to improve the quality of the machined surface.

(2) Select appropriate tools and fixtures to ensure machining accuracy and surface quality.

(3) Keep the cutting fluid clean and sufficient during the processing to reduce the influence of cutting heat on the surface quality.

Solutions to low processing efficiency:

(1) Adjust the processing parameters of the machine tool, such as cutting speed, feed speed, cutting depth, etc., to improve processing efficiency.

(2) Use efficient tools and fixtures to reduce processing time.

(3) Optimize the machining process to reduce cutting time and non-machining time.

Problems in CNC processing are inevitable, but by adopting appropriate solutions, the impact of problems can be effectively reduced and processing quality and efficiency can be improved.
