What is wrong with the improper arrangement of CNC machining?

The use of CNC processing equipment for processing, high efficiency, good quality, but if the process design is not properly arranged, it does not reflect its advantages. From the experience of some CNC processing plants, there are some problems as follows:




CNC machining process is too scattered


The reason for this problem is that it is troublesome (referring to preparation time), simple programming, simplified operation processing, easy to adjust the knife with a knife, and accustomed to ordinary processing. This results in product quality (position tolerance) that is not easily guaranteed, and production efficiency does not work well.

Therefore, CNC machining technicians and operators should be fully familiar with the knowledge of CNC machining, and try more to grasp the relevant knowledge, and use the method of process concentration as much as possible to process. If it is used several times, it will naturally reflect its advantages. After the process concentration, the unit processing time increased. We arranged the two devices face to face, realizing one person to operate two devices, the efficiency was greatly improved, and the quality was well guaranteed.



CNC machining order is unreasonable


Some CNC machining operators often make the processing sequence extremely unreasonable considering some problems in preparation. CNC machining is usually processed according to the requirements of general machining process. For example, the first coarse and then fine (changing the knife), first and then the outside, the reasonable selection of cutting parameters, etc., so that the quality and efficiency can be improved.

In CNC machining, special attention should also be paid to enhancing the retrieval and commissioning of the program. After the program is input to the control system, the operator should use the SCH key and the ↑, ↓, ←, → move keys to make uncertainties and determine the search, and if necessary, modify the program to ensure the accuracy of the program.


At the same time, before the formal execution of the program processing, the program must be tested (open the amplifier) ​​to confirm whether the processing route is consistent with the design route.

What are the characteristics of the CNC turning process?

What are the characteristics of the CNC turning process? Turning is a method of cutting the workpiece on the lathe by rotating the workpiece relative to the tool. Turning is the most basic and common cutting processing method. Most workpieces with revolving surfaces can be processed by turning methods, such as inner and outer cylindrical surfaces, inner and outer conical surfaces, end surfaces, grooves, threads, and rotary forming surfaces. Common lathes can be divided into horizontal lathes, floor lathes, vertical lathes, turret lathes and profiling lathes, and most of them are horizontal lathes.

The Influence of CNC Turning and Milling Machining on Turning Efficiency

The cutting efficiency of CNC lathes will be affected by human factors, environmental factors and the machine tool itself. Let's talk about the influence of cutting amount and cutting tools on CNC lathe processing among many factors.   Reasonable cutting amount can improve the efficiency of CNC lathe. When the   laser  cutting  speed is increased by 10 times and the feed rate is increased by 20 times, far beyond the traditional cutting forbidden zone, the cutting mechanism has undergone a fundamental change.   The result of CNC turning  and milling combined processing is: the metal removal rate per unit power is increased by 30% to 40%, the cutting force is reduced by 30%, the cutting life of the tool is increased by 70%, and the cutting left on the workpiece is greatly reduced. Heat, cutting vibration almost disappeared; cutting processing has taken an essential leap. According to the current situation of CNC lathes, increase the feed per tooth, improve pr...

Machining and welding process notes for TC4 titanium alloy parts

Common welding methods for titanium and titanium alloys are as follows: Argon arc welding, submerged arc welding, vacuum electron beam welding, etc. Tungsten argon arc welding is used for thicknesses of 3 mm or less, and argon arc welding is done for 3 mm or more. The purity of argon is over 99.99%, and the content of air and water vapor in argon is strictly controlled. Currently, for TC4 titanium alloys, argon arc welding, plasma arc welding are often used for welding, but both methods need to be filled with welding material. Limitations on shield gas, purity and effectiveness increase the oxygen content of the joint, reduce its strength and increase its post-weld deformation. Electron beam welding and laser beam welding are used. The following is a description of precision welding and precautions for TC4 titanium alloy. 1. Weld hole problem Table of Contents 1.
